Biological effects of naturally occurring and man-made fibres: in vitro cytotoxicity and mutagenesis in mammalian cells. (1/97)

Cytotoxicity and mutagenicity of tremolite, erionite and the man-made ceramic (RCF-1) fibre were studied using the human-hamster hybrid A(L) cells. Results from these fibres were compared with those of UICC Rhodesian chrysotile fibres. The A(L) cell mutation assay, based on the S1 gene marker located on human chromosome 11, the only human chromosome contained in the hybrid cell, has been shown to be more sensitive than conventional assays in detecting deletion mutations. Tremolite, erionite and RCF-1 fibres were significantly less cytotoxic to A(L) cells than chrysotile. Mutagenesis studies at the HPRT locus revealed no significant mutant yield with any of these fibres. In contrast, both erionite and tremolite induced dose-dependent S1- mutations in fibre-exposed cells, with the former inducing a significantly higher mutant yield than the latter fibre type. On the other hand, RCF-1 fibres were largely non-mutagenic. At equitoxic doses (cell survival at approximately 0.7), erionite was found to be the most potent mutagen among the three fibres tested and at a level comparable to that of chrysotile fibres. These results indicate that RCF-1 fibres are non-genotoxic under the conditions used in the studies and suggest that the high mesothelioma incidence previously observed in hamster may either be a result of selective sensitivity of hamster pleura to fibre-induced chronic irritation or as a result of prolonged fibre treatment. Furthermore, the relatively high mutagenic potential for erionite is consistent with its documented carcinogenicity.  (+info)

Chrysotile, tremolite and fibrogenicity. (2/97)

Recently published analyses have shown that the risks of mesothelioma and lung cancer in Quebec chrysotile miners and millers were related to estimated level of fibrous tremolite in the mines where they had worked. An analysis has therefore been made of radiographic changes in men who in 1965 were employed by companies in Thetford Mines where the same question could be examined for fibrogenicity. Of 294 men who met the necessary requirements, 129 had worked in six centrally located mines, where the tremolite content was thought to be high, 81 in 10 peripheral mines where it was thought to be low and 84 in both. The median prevalence of small parenchymal opacities (> or = 1/0) in chest radiographs read by six readers was higher among men ever than never employed in the central mines (13.6% against 7.4%), despite the fact that the mean cumulative exposure was lower in the former (430 mpcf.y vs 520 mpcf.y). After accounting by logistic regression for cigarette smoking, age, smoking-age interaction and cumulative exposure, the adjusted odds ratio for central mine employment was 2.44 (95% lower bound: 1.06). Together with other surveys of asbestos miners and millers, this study suggests that amphibole fibres, including tremolite, are more fibrogenic than chrysotile, perhaps to the same extent that they are carcinogenic, though the data available were not sufficient to address the latter question.  (+info)

Environmental exposure to tremolite and respiratory cancer in New Caledonia: a case-control study. (3/97)

A case-control study on respiratory cancers was conducted in New Caledonia (South Pacific), where a high incidence of malignant pleural mesothelioma had been observed. The disease pattern suggested an environmental exposure to asbestos. The first results showed that, in some areas, tremolite asbestos derived from local outcroppings was used as whitewash (locally named "po"). All cases diagnosed between 1993 and 1995 (including 15 pleural mesotheliomas, 228 lung cancers, and 23 laryngeal cancers) and 305 controls were included in the study. Detailed information on past or present use of the whitewash, residential history, smoking, diet, and occupation was collected. The risk of mesothelioma was strongly associated with the use of the whitewash (odds ratio (OR) = 40.9; 95% confidence interval (CI): 5.15, 325). All Melanesian cases had been exposed. Among Melanesian women, exposure to the whitewash was associated with an increased risk of lung cancer (OR = 4.89; 95% CI: 1.13, 21.2), and smokers exposed to po had an approximately ninefold risk (OR = 9.26; 95% CI: 1.72, 49.7) compared with women who never smoked and had never used the whitewash. In contrast, no association was noted between exposure to po and lung cancer risk among Melanesian men, probably because of lower exposure levels. Among non-Melanesians, the numbers of exposed subjects were too small to assess the effect of exposure to po. There was no indication of elevated risks for the other cancer sites.  (+info)

The quantitative risks of mesothelioma and lung cancer in relation to asbestos exposure. (4/97)

Mortality reports on asbestos exposed cohorts which gave information on exposure levels from which (as a minimum) a cohort average cumulative exposure could be estimated were reviewed. At exposure levels seen in occupational cohorts it is concluded that the exposure specific risk of mesothelioma from the three principal commercial asbestos types is broadly in the ratio 1:100:500 for chrysotile, amosite and crocidolite respectively. For lung cancer the conclusions are less clear cut. Cohorts exposed only to crocidolite or amosite record similar exposure specific risk levels (around 5% excess lung cancer per f/ml.yr); but chrysotile exposed cohorts show a less consistent picture, with a clear discrepancy between the mortality experience of a cohort of xhrysotile textile workers in Carolina and the Quebec miners cohort. Taking account of the excess risk recorded by cohorts with mixed fibre exposures (generally<1%), the Carolina experience looks uptypically high. It is suggested that a best estimate lung cancer risk for chrysotile alone would be 0.1%, with a highest reasonable estimate of 0.5%. The risk differential between chrysotile and the two amphibole fibres for lunc cancer is thus between 1:10 and 1:50. Examination of the inter-study dose response relationship for the amphibole fibres suggests a non-linear relationship for all three cancer endpoints (pleural and peritoneal mesotheliomas, and lung cancer). The peritoneal mesothelioma risk is proportional to the square of cumulative exposure, lung cancer risk lies between a linear and square relationship and pleural mesothelioma seems to rise less than linearly with cumulative dose. Although these non-linear relationships provide a best fit ot the data, statistical and other uncertainties mean that a linear relationship remains arguable for pleural and lung tumours (but not or peritoneal tumours). Based on these considerations, and a discussion fo the associated uncertainties, a series of quantified risk summary statements for different elvels of cumulative exposure are presented.  (+info)

Amphibole fibres in Chinese chrysotile asbestos. (5/97)

Ten chrysotile bulk samples originating from six Chinese chrysotile mines were studied for amphibole fibres. Five of the mines operate on ultramafic rocks whereas one exploits a dolomite-hosted deposit. The asbestos fibre content in lung tissue was examined from seven deceased workers of the Shenyang asbestos plant using these raw materials. The bulk samples were pretreated with acid/alkali-digestion, and thereafter, scanning and transmission electron microscopy, X-ray microanalysis, selected area electron diffraction and X-ray powder diffractometry were used to identify the minerals. Sample preparation of lung tissue involved drying and low-temperature ashing. All of the bulk samples contained amphibole fibres as an impurity. The amphibole asbestos contents were between 0.002 and 0.310 w-%. Tremolite fibres were detected in every sample but anthophyllite fibres were present only in the sample originating from the dolomite-hosted deposit. In comparison, anthophyllite (71%), tremolite (9%) and chrysotile (10%) were the main fibre types in the lung tissue samples indicating faster pulmonary clearance of chrysotile fibres. The total levels ranged from 2.4 to 148.3 million fibres (over 1 microm in length) per gram of dry tissue, and they were consistent with heavy occupational exposure to asbestos.  (+info)

Erionite bodies and fibres in bronchoalveolar lavage fluid (BALF) of residents from Tuzkoy, Cappadocia, Turkey. (6/97)

OBJECTIVES: The high incidence of malignant mesothelioma in some villages of Cappadocia (Turkey) is due to environmental exposure to erionite fibres. The aim was to evaluate the fibre burden in bronchoalveolar lavage fluid (BALF) from inhabitants of an erionite village and compare it with Turkish subjects with or without environmental exposure to tremolite asbestos. METHODS: Ferruginous bodies (FBs) and fibres were measured and analyzed by light and transmission electron microscopy (TEM) in the BALF of 16 subjects originating from Tuzkoy. RESULTS: FBs were detected in the BALF of 12 subjects, with concentrations above 1 FB/ml in seven of them. Erionite was the central fibre of 95.7% of FBs. Erionite fibres were found in the BALF of all subjects, by TEM, and these fibres were low in Mg, K, and Ca compared with erionite from Tuzkoy soil. The mean concentration of erionite fibres in BALF was similar to that of tremolite fibres in Turks with environmental exposure to tremolite. The proportion of fibres longer than 8 microm in BALF represented 35.6% for erionite compared with 14.0% for tremolite. The asbestos fibre concentrations in erionite villagers was not different from that in Turks without environmental exposure to tremolite. CONCLUSION: Analysis of BALF gives information about fibre retention in populations environmentally exposed to erionite for whom data on fibre burden from lung tissue samples are scarce. This may apply to exposed Turks having emigrated to other countries.  (+info)

Dustiness of different high-temperature insulation wools and refractory ceramic fibres. (7/97)

Recent regulations are encouraging the replacement of older types of man-made mineral fibre by more soluble and, thus, less biopersistent compositions. In order for there to be any health benefits from this policy and to gain maximum benefit from such substitutions, the use of the new materials should not increase exposure. The work reported here was undertaken to investigate the use of new high-temperature glass insulation wools in place of refractory ceramic fibres (RCF). Airborne fibre levels occurring during the manufacture of both RCF and calcium magnesium silicate wools (CMS) were compared using measurements of genuine workplace exposure from a routine monitoring operation on the same plant. Exposures during use were compared in one customer facility where RCF and CMS blankets were used for the same task. Further comparisons were made in a laboratory test of dustiness using a "shaking box test". For some manufacturing tasks there are only a few workplace samples and there are few opportunities for genuine comparisons with both RCF and CMS in identical uses. However, both materials produced very similar exposure levels during manufacture, use and in the laboratory test. The novel magnesium silicate fibre was significantly dustier in the laboratory test.  (+info)

p53, p21 and metallothionein immunoreactivities in patients with malignant pleural mesothelioma: correlations with the epidemiological features and prognosis of mesotheliomas with environmental asbestos exposure. (8/97)

The aim of this study is to investigate immunoreactivity for p53, p21 and metallothionein in diffuse malignant pleural mesothelioma (DMPM) and to determine the relationships between the age, sex, asbestos exposure time, survival of DMPM patients with environmental asbestos exposure and immunoreactivity to p53, p21 and metallothionein. Sixty-seven histopathologically-confirmed DMPMs, 38 of whom had environmental and 29 had occupational asbestos exposure, were included. The tumour tissue samples were immunostained with antibodies against p53, p21 and metallothionein. Epidemiological data and the survival times for the DMPM patients with environmental asbestos exposures were obtained from hospital records. Thirty-three per cent of the DMPMs were positive for p53, 35% for p21 and 52% for metallothionein. There was no statistical difference between the histological subtypes of DMPM in terms of immunoreactivity for p53, p21 and metallothionein. For p21 and metallothionein there was a statistically significant difference between the exposure characteristics: patients with environmental asbestos exposure had shown more immunopositivity. There were statistically significant differences between age groups and between asbestos exposure times for metallothionein, and between asbestos exposure times and p21. The patients with positive immunostaining had longer exposure times and were older than those having negative immunostaining. The differences between survival of the patients were not statistically significant in terms of the immunohistochemical results for p53, p21 and metallothionein.  (+info)

Environmental exposure to silicate compounds such as silica and asbestos has been associated with increased autoimmune responses and the development of autoimmune disease in humans. Residents of Libby, MT have experienced significant asbestos exposure due to an asbestos contaminated vermiculite mine near the community over several decades. Residents have developed numerous asbestos-related diseases as well as increased autoimmune responses. However, the exact mechanism by which Libby amphibole asbestos generates autoimmune responses is unclear. To elucidate a possible mechanism for asbestos induced autoimmunity, the cellular effects of Libby amphibole asbestos were characterized in vitro using a phagocytic murine macrophage cell line, which are characteristic of alveolar macrophages. Our results indicate that Libby amphibole asbestos generates oxidative stress in murine macrophages similar to crocidolite asbestos. However, Libby asbestos induces distinct cellular effects compared to crocidolite asbestos
Libby, Montana, a small town nestled in the northwestern corner of the state, is a humble town, a great destination for anglers and hunters. What many people don't know about Libby, is the lurking danger hanging over the heads of the 3,000 or so Libby residents. Located nearby is an old vermiculite mine that has created a health hazard dealing with asbestos. The old mine was used for acquiring vermiculite, that was used for insulation, shingles, and other construction materials. Imbedded in the vermiculite is a form of asbestos that was released into the air when the vermiculite was processed, creating an abundance of the fibers released into the atmosphere around Libby. The health risk, amplified by human activity, has always been a health hazard due to natural geologic deposits of vermiculite containing asbestos, in and around the Libby area.

Tremolite is a member of the amphibole group of silicate minerals with composition: ☐Ca2(Mg5.0-4.5Fe2+0.0-0.5)Si8O22(OH)2. Tremolite forms by metamorphism of sediments rich in dolomite and quartz. Tremolite forms a series with actinolite and ferro-actinolite. Pure magnesium tremolite is creamy white, but the color grades to dark green with increasing iron content. It has a hardness on Mohs scale of 5 to 6. Nephrite, one of the two minerals of the gemstone jade, is a green variety of tremolite. The fibrous form of tremolite is one of the six recognised types of asbestos. This material is toxic and inhaling the fibers can lead to asbestosis, lung cancer and both pleural and peritoneal mesothelioma. Fibrous tremolite is sometimes found as a contaminant in vermiculite, chrysotile (itself a type of asbestos) and talc. Tremolite is an indicator of metamorphic grade since at high temperatures it converts to diopside. Tremolite occurs as a result of contact metamorphism of calcium and magnesium rich ...
Gunter takes exception to a recent legal definition of asbestos; but there is more to that story. For over 70 years, the fibrous amphibole that is a major-not trace-constituent in the Vermiculite Mountain vermiculite deposit near Libby, Montana, was called tremolite, sodium-rich tremolite, or sodic tremolite by everyone including the mineralogists and geologists who studied the deposit. During the 1970s, the names of the regulated asbestos minerals, including tremolite asbestos, were entered into the U.S. Code of Federal Regulations. As recent court proceedings have revealed, company geologists, owners, and operators of the vermiculite mine near Libby understood that the asbestiform amphiboles in the mine fell under those regulations. In 1978 and 1997, committees of the International Mineralogical Association published new recommendations for amphibole nomenclature. Based on this new system of nomenclature, most of the amphibole minerals at the Libby mine were reclassified as winchite. When ...

We conducted experiments to examine the effect of amphibole-forming hydration reactions on mineral fabric development and the strength of mafic rocks. Both hydrostatic and general shear deformation experiments were conducted on powdered basalt with added water at lower continental crust conditions (800 °C, 1 GPa). Amphibole that formed under hydrostatic conditions exhibits a random lattice-preferred orientation (LPO). In contrast, amphibole formed during deformation exhibits both a strong shape-preferred orientation (SPO) and LPO with a [001] maximum aligned subparallel to the shear direction. Plagioclase in both hydrostatic and deformed samples shows a very weak to random LPO. At low effective strain rates (10−5 s−1 to 10−6 s−1), the stress exponent is ≈1-1.5, consistent with deformation accommodated by diffusion creep. The correlation of the SPO and LPO coupled with the rheological evidence for diffusion creep indicates that the amphibole fabric results from oriented grain growth ...

Anthophyllite is an amphibole mineral: ☐Mg2Mg5Si8O22(OH)2 (☐ is for a vacancy, a point defect in the crystal structure), magnesium iron inosilicate hydroxide. Anthophyllite is polymorphic with cummingtonite. Some forms of anthophyllite are lamellar or fibrous and are classed as asbestos. The name is derived from the Latin word anthophyllum, meaning clove, an allusion to the most common color of the mineral. Anthophylite is the product of metamorphism of magnesium-rich rocks, especially ultrabasic igneous rocks and impure dolomitic shales. It also forms as a retrograde product rimming relict orthopyroxenes and olivine, and as an accessory mineral in cordierite-bearing gneisses and schists. Anthophyllite also occurs as a retrograde metamorphic mineral derived from ultramafic rocks along with serpentinite. Geographically, it occurs in Pennsylvania, southwestern New Hampshire, central Massachusetts, Franklin, North Carolina, and in the Gravelly Range and Tobacco Root Mountains of southwest ...
Abstract: There has been considerable discussion in the literature related to the use of standard optical properties of commercial asbestos minerals for the classification of amphibole minerals found in raw materials as either asbestiform or as non-asbestos (1-4). The goal of this study was to ascertain if there is a relationship between particle morphology and extinction characteristics in monoclinic tremolite amphiboles. Six tremolitic amphiboles were chosen for this study: three are fibrous (five from natural sites (i.e., mining locales)) and one is the NIST SRM 1867a tremolite standard. The morphology of these tremolites ranged from blocky to asbestiform. A particle-by-particle analysis was performed to determine extinction characteristics and the number of EPA-defined asbestos characteristics. In general, zero or near-zero extinction angles correlate to the number of asbestiform characteristics. Exceptions to this occur when a non-fibrous tremolite has (100) parting as a result of twinning ...

Ferro-edenite is an uncommon amphibole mineral. It is almost exactly the same as the more common amphibole mineral edenite, but contains more iron than magnesium thus the name ferro-edenite (ferro is latin for iron). The two minerals form a solid solution series in which the iron and magnesium substitute for each other. Edenite is the magnesium rich member. The two are similar in properties except that ferro-edenite is generally darker and denser. Ferro-edenite is related to the more well known amphibole, hornblende. Although hornblende is no longer an official mineral, it still serves as a general name for iron, magnesium, aluminum and calcium rich amphiboles of which ferro-edenite is one. In fact ferro-edenite had been referred to as ferro-edenitic hornblende before its adoption as an official and distinct mineral. Amphiboles like ferro-edenite, edenite and hornblende serve as important petrographic minerals. Their presence allows petrologists (rock scientists) to accurately gauge the ...
Amphiboles along the tremolite-pargasite join have been hydrothermally synthesized at 900°C, 3 kbar. Run products were characterized by optical and electron microscopy, powder X-ray diffraction and infrared spectroscopy. Under the experimental conditions used, there is complete solid-solution between tremolite and pargasite and the variation of cell parameters is linear as a function of composition. The infrared spectra in the principal OH-stretching region are consistent with the predictions of Hawthorne (1997) on local bond-valence grounds, and show strong short-range order of cations at the octahedral sites and strong coupling between Al at T(l) and Na at A. ...
Hornblende is an important constituent of many igneous rocks. It is also an important constituent of the rock known as amphibolite, formed by metamorphism of basalt.. Actinolite is an important and common member of the monoclinic series, forming radiating groups of acicular (needle-like) crystals of bright green or grayish-green color. It occurs frequently as a constituent of greenschists. The name (from Greek ακτις/aktis, a ray and λιθος/lithos, a stone) is a translation of the old German word Strahlstein (radiated stone).. Glaucophane, crocidolite, riebeckite and arfvedsonite form a somewhat special group of alkali amphiboles. The first two are blue fibrous minerals, with glaucophane occurring in blueschists and crocidolite (blue asbestos) in ironstone formations-both result from dynamo-metamorphic processes. The latter two are dark green minerals that occur as original constituents of igneous rocks rich in sodium, such as nepheline-syenite and phonolite.. Pargasite is a rare, ...

At its peak, the Libby mine may have provided 80 percent of the worlds vermiculite, most of which was contaminated with what would become known as Libby Amphibole Asbestos. The contamination was not limited just to the mine site; Libby residents were able to pick up free truckloads of asbestos-contaminated vermiculite for use at home. The vermiculite was used to pave driveways and in public areas (boat ramps, ice rink, running track, baseball fields and school yards). Children played in piles of vermiculite that could be found throughout the community. Also, attic insulation contaminated with Libby asbestos may still be in schools, businesses and as many as 35 million homes around the United States alone ...
Properly removing vermiculite from your home or office building requires expert assistance to ensure all traces of the harmful material is completely cleaned, and no harmful airborne fibres manage to spread. At Scott Asbestos, our team of professional cleaners are ready to take every precaution to ensure the vermiculite contamination in your property is properly dealt with. Vancouver, along with a number of other major residential areas of the lower mainland features a number of homes and properties that were built with materials containing vermiculite. Between 1970 and the early 1990s, a large number of construction companies made use of the vermiculite found in one mine in Montana. Unfortunately, it was later discovered that the vermiculite found in this mine had been contaminated with tremolite asbestos. Despite its effective insulation properties and the ease in which it can be installed, vermiculite is among one of the most hazardous building materials which can be found in BC homes and ...
A deposit in Libby, Montana was the largest in the world and 70 percent of all vermiculite sold in the United States between 1919 and 1990 was from Libby. There was a problem, though, with this source of vermiculite. It was contaminated with tremolite asbestos, a particularly dangerous form of asbestos. When the vermiculite was mined, millions of asbestos fibers were sent into the air sickening miners, their families, and townspeople.. Not only was asbestos sent into the air, ore from the mine was donated to schools to make running tracks, an ice rink, and was mixed with other materials to make baseball fields. Every day kids were exposed to asbestos when they played outside. A popping plant, where ore was taken to expand, was located next to baseball fields.

The accurate measurement of annual average mineral fiber concentrations at various air sampling sites provides the best index of non-occupational inhalation exposure to fibers in a community located near an industrial source of airborne amphibole fibers. The transmission electron microscope analysis of enough individual high volume air samples to provide annual average fiber concentrations is not feasible because of the great time and expense required. X-ray diffraction analysis of air samples collected on membrane filters over periods of several days offers a reliable measurement of amphibole mineral mass concentration. An excellent linear correlation (r = 0.94 for N = 12) exists between the amphibole mass concentrations (x-ray diffraction) and amphibole fiber concentrations (transmission electron microscope). The correlation equation is used to calculate amphibole fiber concentrations from over 300 x-ray diffraction analyses. The accuracy and precision of both techniques are discussed as well ...

Asbestos is a naturally occurring rock forming mineral silicate in fibrous form belonging to the serpentine and amphibole groups. It occurs naturally in large deposits on every continent in the world. There are six types of naturally occurring asbestos fibres of which only three have been used commercially in Australia. These included the serpentine: Chrysotile (white asbestos); and the amphiboles: Crocidolite (blue asbestos) and Amosite (brown or grey asbestos). The other three non-commercially used amphiboles included Tremolite, Actinolite and Anthophyllite.. Asbestos has been used in the ancient world of the Egyptians, Greeks and Romans. It is believed that as early as 4000 BC, asbestos fibres were used for wicks in lamps and candles. Between 2000-3000 BC, embalmed bodies of Egyptian pharaohs were wrapped in asbestos cloth. The Greeks and Romans documented the harmful effects of asbestos fibres on those who mined the silken material from ancient stone quarries noting a sickness of the lungs ...
The U.S. Environmental Protection Agency has released early results on research being done in Libby, Montana to monitor the air quality and make progress towards cleaning up a town that has dealt with an increased risk of deadly asbestos exposure for decades now. The data, which was presented during a meeting at the Libby Memorial Center, was described as a preliminary draft estimate. The final draft of the information will be used to determine how dangerous the air is in Libby after decades of Amphibole asbestos mining and attempts to decrease the risk of asbestos exposure in the future. For more than a decade, EPA has worked in this community to clean up the pollution left behind by 40 plus years of mining operations. Under this administration, EPA has stepped up its commitment to provide the best science to finish the job of protecting the health and future of the people of Libby, said Jim Martin, the EPAs Regional Administrator in Denver. Once we finalize these toxicity estimates, they ...
Cincinnati, OH - Workers exposed to low levels of an asbestos-like mineral from Montana more than two decades ago are at an increased risk for lung disease today, according to research from the University of Cincinnati (UC).. Vermiculite is a mineral with a flaky, fluffy-looking structure. Previous studies revealed that the vermiculite ore mined in Libby, Mont., contained increased levels of an asbestos-like mineral fiber that can become airborne and inhaled when used in manufacturing.. In a 25-year follow-up study of workers at a plant which stopped using Libby vermiculite in 1980, current chest X-rays revealed that 20 percent of workers who experienced low cumulative exposure to these fibers had changes in the lining around their lungs. In the group with the highest exposure, changes on chest X-rays were noted in 54 percent of workers.. James Lockey, MD, senior research investigator, says the study indicates that this particular asbestos-like mineral contained in the Libby vermiculite ore can ...

Amphibole (Angel Phantom) Quartz is a quartz that contains inclusions of minerals in varied amounts and proportions, including Riebeckite, Actinolite, Tremolite, Richterite and Lithium. These show as opaque inclusions in layers or cloudy deposits, in a range of colours including white, yellow-gold, red, orange and plum. Even though not all minerals might be visible within the specimen the energies of the crystals will resonate in much the same way, the influence of the minerals becoming an integral part of their makeup.As the name suggests, many find this crystal useful in accessing and working with the Angelic Realms, although its clarity and colouring may affect the effectiveness of this. I have found that the energies of this crystal to be quite complex, and thus perhaps I feel that it aids connection with Higher intelligences that have more complex information to convey, or with those Angelics who wish to work with us on complex issues that mean a bit of hard work on our part!

2017 Elsevier B.V.Primary ore-forming minerals retain geochemical signatures of magmatic crystallization information and can reveal the petrochemical conditions prevalent at the time of their formation. The Baogutu deposit is a typical reduced porphyry Cu deposit. Amphibole and biotite Fe3+/SFe ratios, minerals (feldspar, biotite, amphibole, zircon and apatite), in situ elemental and apatite Nd isotopic compositions were determined by Mössbauer spectroscopy, electron probe microanalysis, and laser ablation multiple-collection inductively coupled plasma mass spectrometry, respectively, to investigate the magma oxidation state, petrogenesis, source features, and to constrain the carbon species at magmatic stages for the intrusive phases. The results show that the primary plagioclase and amphibole in the mineralized diorite to granodiorite porphyry and post ore hornblende diorite porphyry are distinct (An26-55 versus An60-69; Mg-hornblende versus tschermakite). In particular, the amphibole shows ...

Asbestos in Construction What is Asbestos? Asbestos is the name given to a group of naturally occurring minerals. Asbestos differs from other minerals, in that it forms long thin fibers instead of crystals. There are six different minerals, divided into two groups, included in the asbestos family. The two groups are Serpentine and Amphibole, and are based on the differences of their crystalline structure. Serpentine forms a sheet or layered structure. Amphiboles form a chain-like structure. Asbestos fibers are naturally occurring and stay airborne very well. Where do you find asbestos? Asbestos is used in many products because of their high tensile strength, flexibility,.... ...
Many people wonder if they are, or have been, subject to the risks of asbestos exposure. Health hazards from asbestos dust have been recognized in workers exposed in shipyards, power generating stations, oil refineries, steel mills, paper mills, foundries, asbestos mining and milling, manufacturing of asbestos textiles and other asbestos products, insulation work in the construction and building trades, auto mechanics, and a variety of other trades. Demolition workers, drywallers, plumbers, electricians, carpenters, sprinkler fitters, ironworkers, and firefighters also may be exposed to asbestos dust. People whose work brings them into contact with asbestos workers who renovate buildings with asbestos in them, for example may inhale fibers that are in the air: this is called occupational exposure. Workers families may inhale asbestos fibers released by clothes that have been in contact with ACM: this is called paraoccupational exposure. People who live or work near asbestos-related operations ...
In a controversial article, The Great Asbestos Hysteria (Mail, February 23), we said that according to the Health and Safety Executive, the risks from white asbestos products are insignificant, and arguably zero in the case of lung cancer. The HSE assessments related to specific levels of exposure to white asbestos fibres, not white asbestos products, and found a risk from higher levels. The article said that asbestos in UK schools is almost all white. According to the HSE, the more harmful brown asbestos was also frequently used in schools. The writer was in error in saying that the HSE had been forced to withdraw a series of commercials claiming that mesothelioma kills 4,500 a year. In fact, the advertisements were based on an estimate of 4,000 deaths from all asbestos-related disease.
There are six main types of asbestos, broken into two separate categories. These two categories are:. Serpentine: meaning snake like or curly in appearance. Amphibole: characterized by straighter fibers. The serpentine group has only one member - chrysotile, which accounts for over 90% of all asbestos in world production. This asbestos is white or green in color and is often used as insulation or for fireproofing products. With its widespread usage, chrysotile is responsible for most asbestos-related health problems.. The amphibole group contains the other five types of asbestos. Of these, amosite and crocidolite are the only two used for commercial purposes. These two are characterized by strong, stiff fibers and are consider highly dangerous when these airborne fibers are inhaled or ingested.. Amosite, brown-asbestos, had been banned in many countries for decades but it was still being commercially produced up until this last decade. At one time, it accounted for 5% of the asbestos used in ...
Our sweet daughter, Libby, passed away from sudden and aggressive bile duct and liver cancer. From the moment she came into our lives as a 2 month old puppy until her last day at 6 years old and 7 months, Libby knew only unconditional love; she joined her parents, Julia & Casey, everywhere throughout her happy life - even moving via cross-Atlantic oceanliner from New York to London, where she spent her last two years making friends (especially with the kind barista at our neighborhood cafe who always let Libby come in to get her special croissants!), playing in the lush green grass, snoozing on the couch with her parents, chasing her favorite brown ball, and getting all of the love, cuddles, and treats she rightly deserved. We miss her sweet snorts and huge happy smile everyday - Libby is forever loved. RIP Libby Lou, August 10, 2012 - March 22, 2019. ...

CSR recommendation: Companies must adopt global policies for avoiding the use of new asbestos products and carefully manage in-place asbestos products in existing infrastructure. Update: Please see a letter in response to this posting below the fold from Ban Asbestos Network of India (BANI) - the organisation that published the book. His letter is well worth reading and offers a powerful condemnation of the quote by AK Saraf above. This is with reference to a piece Killing the Future: Asbestos use in Asia on your website published on 8th August, 2007.. BANI objected to the statement of A K Saraf of Asbestos Cement Products Manufacturers Association quoted in the piece is highly misleading.

In 2011, Libby, Montana residents were considering a $43 million asbestos settlement with W.R. Grace & Company, which operated vermiculite mines in town.
Occurrence in Wales: Blake (1888) provided the first description of glaucophane from the British Isles, reporting its occurrence in rocks of his ‘Monian System’ [now known as the Aethwy Terrane or Blueschist Belt (Gibbons & Horák, 1990)] from near Llanfairpwllgwyngyll, Anglesey. Blake’s identification was confirmed by Greenly (1919) who also noted zoning in the amphiboles with green ‘hornblende’ core passing outwards into blue rims. Holgate (1951) provided a chemical analysis on separated rims, but suggested that as the blue amphibole contained a higher Fe3+ to Aliv content, it was crossite and not glaucophane. Macpherson (1983) recalculated Holgate’s analysis and, applying the new IMA amphibole classification, deemed them to be magnesio-arfvedsonites. New microprobe data (Horák & Gibbons, 1986; Gibbons & Gyopari, 1986) showed that the rims fall within the glaucophane-ferroglaucophane series. The Anglesey blueschists occur as poorly-exposed scattered ...

By the fire regulation substation entrance and internal doors must be fire rated. Asbestos was widely used in the internal construction or backing of fire doors due to its excellent fire resistance properties. That includes switchroom fire doors (wooden clad) in the form of core insulation, transformer room entrance doors (steel clad) in the form of mastic insulation, interior entrance and connecting fire doors (wooden clad) in the form of core insulation. They are usually painted gray or some other suitable colour to blend with the surroundings. ...
Asbestos is not one but a group of minerals which all occur naturally as thin fibres. It is this small size however that means they can cause various problems as they can float in the air and be easily breathed in to cause problems in the lungs. The different minerals however of course are slightly different in their appearance and in their effect. Amphibole is made of straight fibres that are much like needles. Amphiboles however are a category themselves and include: actinolite, anthophylite, amosite, crocidolite and termolite. The most commonly found asbestos in commercial products that most people suffer from is chrysotile. Health Problems. Asbestos causes a number of health problems and this is as a result of its being breahted into the lungs. Of the health complications that asbestos can cause, the most common are: asbestosis, mesothelioma and lung cancer. Absestosis is caused by the physical presence of asbestos in the lungs which causes scarring and fibrosis. Mesothelioma meanwhile is a ...
Prior to the late 1970s, the health hazards of asbestos exposure were a closely guarded secret by the large corporate and business interests involved in the manufacture and sales of asbestos products. Evidence of the connection between asbestos exposure and respiratory disease existed as far back as 1897; by 1931, the use of asbestos was tightly regulated in the U.K.. No such regulations existed in the U.S., however. Although scientific studies (many commissioned by asbestos and insurance corporations themselves) clearly showed that asbestos was the cause of respiratory disease, the industry itself engaged in a conspiracy of silence. Even the U.S. government was complicit, although government agencies did in fact issue safety guidelines in 1943. These guidelines did not have the force of law, however, and were rarely enforced ...

The cause of the disease is linked to the exposure to asbestos, and shipbuilding throughout the world featured hundreds of asbestos products used for insulation, including those vessels used in the British Armed Forces. The material was considered ideal for use aboard ships until the 1980s. Asbestos could be found in the engine and boiler rooms, as well as in the walls, floors and ceilings of rooms such as the sleeping quarters and the galley. Both shipbuilders and those who served on military vessels could have inhaled airborne asbestos fibres while working on the ships ...
Its a fair complaint, on its face. I get plenty of those press releases from environmental groups and read those same news stories, and the only consistent reporting Ive seen about Libby over the last few years has been from New West.net. But the question is whether thats because the media or activists or environmental groups care less about people than, say, polar bears, or wolves, or reforming an archaic mining law that stacks the deck in favor of the W.R. Graces of the world to exploit communities along with the natural resources theyre after. I think there are a number of factors at play here to account for the relative quiet about Libby, and few of them have to do with a lack of horror at what has happened to the people of Libby. And probably none of them made that jury in Missoula acquit Grace and the former executives of the company. The tunnel vision of interest groups is legendary. No matter the issue area, these groups find a niche, and stick in it, often working at odds with ...

Libby has been accused of being an intelligence agent for Israels Mossad. That sounds about right. I believe the technical term is Sayanim, although Libby, due to his background and position, may be a step or two above a sleeper agent (see also here, and from a dodgy source with good info, here; btw, have you noticed that the traditional dodgy sources are finding more acceptance in the mainstream, due to the fact that they are the pioneers in certain areas of truth?). There has long been speculation that the Mossad has a hidden spy-chief in the upper reaches of the American government. Libby is the most spectacular example of the phenomenon of so-called dual loyalties (so-called as his only real loyalty is to Israel), and the commutation of his political sentence is part of the education process for the greater American public about this important problem ...
Objectives Cancer risk has been estimated for asbestos production workers or other heavily exposed asbestos workers in numerous studies. The bulk of the asbestos epidemic results come, however, from past intermittent exposures during asbestos product use. This study concentrated on estimating the risk of cancer in such a population.. Methods Altogether 23 285 men and 930 women invited to a nationwide screening campaign for benign asbestos-related diseases in 1990-1992 were followed for cancer through the Finnish Cancer Register up to 1998. Standardized incidence ratios (SIR) were calculated in comparison with the total Finnish population.. Results Altogether 1392 cases of cancer were found among the men. The risk was slightly, but significantly elevated for lung cancer [SIR 1.14, 95% confidence interval (95% CI) 1.01-1.26), mesothelioma (SIR 2.77, 95% CI 1.66-4.31), and prostate cancer (SIR 1.21, 95% CI 1.09-1.34).
