Hexavalent chromium responsible for lung lesions induced by intratracheal instillation of chromium fumes in rats. (1/119)

Lung toxicity of chromium fumes (Cr fumes) was examined by a single intratracheal instillation into rats of 10.6 mg and 21.3 mg Cr fumes/kg body weight and by repeated (3 times) instillations of 10.8 mg and 21.7 mg Cr fumes/kg. The pathological changes were compared with those induced by single administrations of 3.2 mg and 19.2 mg Na2CO3 solution-insoluble fraction of Cr fumes (Cr-Fr)/kg and 20.8 mg commercially available chromium (III) oxide powder (Cr (III) oxide)/kg. Single and repeated administrations of Cr fumes suppressed growth rate in a dose-dependent manner, but administrations of Cr-Fr and Cr (III) oxide did not. A single administration of Cr fumes produced granulomas in the entire airways and alveoli with progressive fibrotic changes, as well as severe mobilization and destruction of macrophages and foamy cells. Those histopathological changes were aggravated by the repeated administration of Cr fumes. On the other hand, single administrations of Cr-Fr and Cr (III) oxide produced no remarkable histopathological changes. Cr fumes were found to be composed of 73.5% chromium (III) oxide and 26.5% chromium (VI) oxide. The primary particles of Cr fumes and Cr-Fr were similar, 0.02 micron in size (sigma g: 1.25), and Cr (III) oxide particles were 0.30 micron in size (sigma g: 1.53), measured by analytical electron microscopy (ATEM). Diffuse clusters of the primary particles in Cr fumes were identified as Cr (VI) oxide. The present results suggested that the lung toxicity of Cr fumes was mainly caused by these Cr (VI) oxide (CrO3) particles in Cr fumes.  (+info)

Recovery of 15N-lactoferrin is higher than that of 15N-casein in the small intestine of suckling, but not adult miniature pigs. (2/119)

Performance of biological functions of lactoferrin in the small intestine requires at least some resistance to degradation. Therefore, we studied prececal digestibility of lactoferrin in comparison to casein both in suckling and adult miniature pigs, applying 15N-labeled proteins. In study 1, 43 piglets (10-d-old), deprived of food for 12 h received 10 mL of sow's milk supplemented with 120 mg of 15N-labeled protein (porcine or bovine lactoferrin or bovine casein). Piglets were anesthetized 150 min later, after which the small intestine was excised, cut into three sections, and chyme was collected. In study 2, nine food-deprived boars fitted with T-canulae at the terminal ileum were given two semisynthetic experimental meals (204 g) in a cross-over design, 2 wk apart. One contained 7.5% (g/100 g) 15N-labeled bovine casein, the other 1.25% 15N-labeled bovine lactoferrin. Both were adjusted to 15% total protein with nonlabeled casein. Ileal chyme was collected from the canula over 33 h postprandially. All diets contained the indigestible marker chromic oxide. 15N-digestibility of lactoferrin, both porcine (84.4 +/- 3.2%) and bovine (82.3 +/- 4.8%), was significantly lower than casein digestibility (97.6 +/- 0.5%) in the distal small intestine of suckling piglets (P < 0.05). Based on immunoblotting after acrylamide electrophoresis, 4.5% of non- and partially digested lactoferrin was found in the last third of the small intestine of piglets. In adult miniature pigs there was no difference in 15N-digestibility of bovine lactoferrin compared to bovine casein (90.7 +/- 1.9% vs. 93.9 +/- 1.0%, P > 0.05). In suckling miniature pigs, the reduced digestibility of lactoferrin may provide the prerequisite for biological actions along the whole intestinal tract. The source of lactoferrin, porcine or bovine, made no difference in this respect.  (+info)

Dietary chromic oxide does not affect the utilization of organic compounds but can alter the utilization of mineral salts in gilthead sea bream Sparus aurata. (3/119)

This study was conducted to determine whether the level of chromic oxide supplemented to diets containing gelatinized starch as the carbohydrate source affects digestibility, body composition, growth performances, and liver enzyme activities in gilthead sea bream, Sparus aurata. Gilthead sea bream fingerlings were fed diets containing gelatinized corn starch as the carbohydrate source and several levels of chromic oxide (0, 5, 10 and 20 g/kg) for 6 wk. No effect of dietary chromium level was detected on carbon, nitrogen, or dry matter digestibility. Calcium and phosphorus digestibility were higher in fish fed the diet supplemented with 5 g/kg chromic oxide than in fish fed the other supplemented diets. Dietary chromium did not affect dry matter, carbon, nitrogen, protein, or lipid concentrations in fish. However, fish fed 5 g/kg chromic oxide generally had higher levels of calcium, phosphorus, and ash than fish fed the other Cr-containing diets. Chromium concentration was significantly higher in fish fed the diets with 0.5 and 1% chromic oxide than in fish fed the control diet. Chromium supplementation of the diets did not affect the specific growth rate, the food efficiency ratio, the protein efficiency ratio, or, protein or nitrogen retention of the fish. Blood glucose and the activity of several liver enzymes involved in carbohydrate metabolism were unaffected by dietary chromic oxide. Alanine aminotransferase was lower in the fish fed the diet with 10 g/kg of chromic oxide than in unsupplemented controls. Our results indicate that chromic oxide can be used as a neutral marker in fish nutrition studies involving organic compounds, but not mineral salts.  (+info)

Treatment of malignant pericardial effusion with 32P-colloid. (4/119)

Malignant pericardial effusion is usually treated only when signs of cardiac tamponade develop. Several methods of treatment have been reported with an overall response rate of approximately 75%. Since our initial study using intrapericardial 32P-colloid instillation as a treatment modality for pericardial effusion demonstrated a significant higher response rate, this study was conducted to further evaluate the efficacy of intrapericardial 32P-colloid in terms of response rates and duration of remissions. Intrapericardial instillation of 185-370 MBq (5-10 mCi) 32P-colloid in 36 patients with malignant pericardial effusion resulted in a complete remission rate of 94.5% (34 patients) whereas two patients did not respond to treatment due to a foudroyant formation of pericardial fluid. The median duration time was 8 months. No side-effects were observed. These results suggest that intrapericardial instillation of 32P-colloid is a simple, reliable and safe treatment strategy for patients with malignant pericardial effusions. Therefore, since further evidence is provided that 32P-colloid is significantly more effective than external radiation or non-radioactive sclerosing agents, this treatment modality should be considered for the management of malignant pericardial effusion.  (+info)

Morphological study on pigmented cells in the horse testis. (5/119)

One of the most attractive characteristics of a horse testis is the change of the weight during development. As the testicular weight changes and the number of Leydig cells decreases, pigments appear in interstitial tissues. In the present study, the characteristics of the pigments found in the interstitial tissues were examined histochemically and ultrastructurally. Specific stainings indicated that the pigmented granules showed almost all of the histological and histochemical characteristics of ceroid or ceroid-like pigment. The cells showed positive reaction for acid phosphatase while the pigmented cells contained a lot of lysosomes ultrastructurally. These results suggest that macrophages might phagocytize Leydig cells, and store their digested materials as ceroid-like pigment.  (+info)

Chromium(III) hydrolytic oligomers: their relevance to protein binding. (6/119)

The nature of chromium(III) complexes has been found to show a profound influence in its interaction with collagen. The hydrothermal stability of rat tail tendon (RTT) fibres treated with dimeric, trimeric and tetrameric species of chromium(III) has been found to be 102, 87 and 68 degrees C, while that of native RTT is 62 degrees C. This shows that the efficiency of crosslinking of collagen by chromium(III) species is dimeric > trimeric > tetrameric. This order of stabilisation is again confirmed by cyanogen bromide (CNBr) cleavage of RTT collagen treated with dimeric, trimeric and tetrameric chromium(III) species. CNBr has been found to cleave the collagen treated with tetrameric chromium(III) species extensively. On the other hand, dimer-treated collagen does not undergo any cleavage on CNBr treatment. The equilibrium constants for the reaction of a nucleophile like NCS(-) to the dimeric, trimeric and tetrameric species of chromium(III) have been found to be 15.7+/-0.1, 14.6+/-0.1 and 1.2+/-0.1 M(-1), respectively. These equilibrium constant values reflect the relative thermodynamic stability of the chromium(III) species-nucleophile complex. The low stabilising effect of the tetrameric species can be traced to its low thermodynamic affinity for nucleophiles.  (+info)

Thirteen-week subchronic rat inhalation toxicity study with a recovery phase of trivalent chromium compounds, chromic oxide, and basic chromium sulfate. (7/119)

The toxicity of trivalent chromium compounds; chromic oxide and basic chromium sulfate, was investigated in rats in a 13-week nose-only inhalation study that included a 13-week recovery period. Nose-only exposures to insoluble chromic oxide dust at 4.4, 15, or 44 mg/m3 or soluble basic chromium sulfate dust at 17, 54, or 168 mg/m3 (trivalent chromium equivalent concentrations of 3, 10, and 30 mg/m3) were carried out for 6 h/day, 5 days/week. No compound-related mortality occurred. General toxic effects, only observed with high-exposure levels of basic chromium sulfate, included sporadic signs of labored breathing and depressed body weights. No apparent compound-related effects were noted for sperm motility or morphology, for any concentration of either test material. Bronchoalveolar lavage fluid evaluations showed test material in mononuclear cells with chromic oxide and increased neutrophils, protein, lactic dehydrogenase and cellular debris with basic chromium sulfate. The principle effects for both materials were primarily to the respiratory tract. Chromic oxide caused pathological changes in the bronchial and mediastinal lymphatic tissue and lungs, consisting of the presence of pigment-laden macrophages, lymphoid and septal hyperplasia, and interstitial inflammation similar to that observed with other inert dusts. Basic chromium sulfate produced more severe and widespread effects in the nasal cavity, larynx, lungs, and mediastinal lymph node. Effects were characterized by accumulation of foreign material, infiltration of alveolar macrophages, septal cell hyperplasia, and granulomatous and chronic inflammation. Pigment was still present in chromic oxide and, to a lesser extent, in basic chromium sulfate-treated animals after the 13-week recovery period, with partial recovery of the pathological lesions. A NOAEL was not established for either test material, but 4.4 mg/m3 was thought to be near the NOAEL level for subchronic exposure to chromic oxide. The results of this study indicate significant differences in toxicity to the respiratory tract between trivalent chromium compounds chromic oxide and basic chromium sulfate. These are likely related to differences in acidity and water solubility, rather than chromium concentration per se. This conclusion is substantiated by the lack of effect on other internal organs.  (+info)

Dissimilatory metal reduction by the facultative anaerobe Pantoea agglomerans SP1. (8/119)

Anaerobic enrichments with acetate as the electron donor and Fe(III) as the terminal electron acceptor were obtained from sediments of Salt Pond, a coastal marine basin near Woods Hole, Mass. A pure culture of a facultatively anaerobic Fe(III) reducer was isolated, and 16S rRNA analysis demonstrated that this organism was most closely related to Pantoea (formerly Enterobacter) agglomerans, a member of the family Enterobacteriaceae within the gamma subdivision of the Proteobacteria. This organism, designated strain SP1, can grow by coupling the oxidation of acetate or H(2) to the reduction of a variety of electron acceptors, including Fe(III), Mn(IV), Cr(VI), and the humic substance analog 2,6-anthraquinone disulfonate, but not sulfate. To our knowledge, this is the first mesophilic facultative anaerobe reported to couple acetate oxidation to dissimilatory metal reduction.  (+info)

OBJECTIVES: To determine whether occupational exposure to chromite, trivalent chromium, or hexavalent chromium causes respiratory diseases, an excess of respiratory symptoms, a decrease in pulmonary function, or signs of pneumoconiosis among workers in an integrated chain of stainless steel production. METHODS: This cross sectional study was carried out in 1993 and the inclusion criterion was a minimum of eight years of employment in the same production department. A self administered questionnaire was collected, and spirometry, measurement of diffusing capacity, chest radiography, and laboratory tests were carried out by a mobile research unit. RESULTS: There were 221 workers in the exposure groups and 95 in the control group. The average duration of employment was 18 years. No significant differences in the odds ratios (ORs) of the symptoms were found between the exposure and the control groups. In a logistic regression analysis age and smoking significantly explained the occurrence of most of ...
which is known per se, by impregnation of the support powder with an aqueous or organic solution of a chromium compound, followed by drying in an oxidizing atmosphere. For this purpose, a chromium compound chosen from soluble salts such as the oxides, acetate, chloride, sulphate, chromate and bichromate in aqueous solution, or such as the acetylacetonate in organic solution, may be used. After impregnation of the support with the chromium compound, the impregnated support is usually activated by heating it to a temperature of from 400 to 1000°C in order to convert at least part of the chromium into hexavalent chromium. The catalytic solid according to the invention may also be obtained by means of mechanical mixing of the support powder with a solid chromium compound, for example chromium acetylacetonate. Next, this mixture may be pre-activated at a temperature below the melting point of the chromium compound, before activating it conventionally as described above. In the catalytic solid used ...

1. INTRODUCTION. Nowadays, heavy metals are among the most important pollutants in source and treated water and becoming a severe public health problem. Chromium, a toxic heavy metal ion, is found in wastewater of various industries, such as paint and pigment manufacturing, stainless steel production, corrosion control, leather tanning, chrome plating and wood preservation [1]. Chromium exists almost exclusively in the Cr(III) oxidation state or in the Cr(VI) oxidation state, however, Cr(VI) is 500 times more toxic than the trivalent form [2]. Thus, the presence of Cr(VI) ions in the environment is posing serious problems and causing great public concern [3]. According to USEPA, the permissible level of Cr(VI) in drinking water should be less than 100 µg/L [4].. Many physical-chemical methods, included reduction [5], ion exchange [6], precipitation [7] and membrane separation [8], have been proposed for Cr(VI) removal from industrial effluent. However, these methods are often inefficient and/or ...
With interest, we read the systematic review by Balk et al. (1). It reviewed the effect of chromium supplementation on glucose metabolism and lipids. It is important to have an update of the systematic review performed by Althuis et al. (2) in 2002, since many studies have been published in the years thereafter.. However, we have some concerns with the conclusions of the current systematic review (1). Althuis et al. (2) excluded the study of Anderson et al. (3), performed in China, in their meta-analysis because this study caused heterogeneity problems. Furthermore, this study, which was rated by Balk et al. (1) as being of poor quality, has by far the most beneficial effects on A1C compared with all other studies. We cannot assess the effects, as they were found by combining the results of the studies with the methodological qualification of "good" in the subanalysis. We guess from Fig. 1 that this effect is about 0.2%, which, if significant, would not be very relevant.. Also, it would have ...

These catalyst systems are especially useful for the oligomerization of olefins, such as, for example, ethylene to 1-hexene. As used in this disclosure, the term "oligomerization" broadly encompasses the combination of two olefins (dimerization) to form an olefinic product, combination of three olefins (trimerization) to form an olefinic product and combination of more than three olefins to form an olefinic product, but does not include polymerization of olefins. An ohgomer can be defined as a compound made up of repeating units, whose properties can change with the addition or removal of one or a few repeating units. The properties of a polymer do not change markedly with such a modification The chromium source can be one or more organic or inorganic chromium compounds, wherein the chromium oxidation state is from 0 to 6.

Chromium is a commonly used (or at least recommended) supplement in PCOS. What is it, why is it recommended, and should you be taking it?. Chromium is a metal, just like iron and copper. Its not really needed in large amounts to do its job, which in the body, is to help metabolize sugar and fats.. Some researchers have suggested that chromium supplementation in PCOS can help insulin function. There are two articles in the National Library of Medicine database looking specifically at the use of chromium supplementation in PCOS. One study, using a dose of 200 mcg per day, resulted in improved glucose tolerance but not fertility. The second study bumped the dose up to 1000 micrograms per day, resulting in a 38% better ability to remove glucose from the blood.. BEFORE YOU RUSH OUT AND BUY A YEARS SUPPLY…. There are more than a few articles in the very same database connecting chromium picolinate to DNA damage. The earliest one, for someone writing so much about infertility, really caught my eye, ...

Chromium can exist in air, water, soil, and food, and common exposure pathways include ingestion, inhalation, or dermal contact. Chromium is commonly found in two forms: trivalent chromium (chromium III) and hexavalent chromium (chromium VI). Chromium III is the most stable form of the element, and occurs naturally in animals, plants, rocks, and soils. Chromium VI rarely occurs in nature, and is usually the product of anthropogenic activities.. The health effects of chromium depend on the route of exposure and the form of the chromium. For example, inhaling chromium can cause damage to the respiratory system, whereas dermal or oral exposures generally do not. Gastrointestinal effects are generally associated with oral exposure, but not with dermal exposure. In addition, chromium VI typically causes greater health risks than chromium III. The reasons for the increased danger of chromium VI versus chromium III are complex, and relate in part to the varied paths of cellular uptake between the two ...
Para-ethyltoluene dehydrogenation catalyst compositions and processes for using such catalysts are provided. The catalyst compositions comprise a catalytically active iron compound, e.g., iron oxide; a potassium catalyst promoter, e.g., potassium carbonate; an optional chromium compound stabilizer, e.g., chromic oxide, and a gallium compound, e.g., gallium trioxide. Utilization of particular amounts of gallium compound in dehydrogenation catalyst compositions of this type will provide a catalyst especially suitable for promoting the selective dehydrogenation of para-ethyltoluene to form para-methylstyrene with sustained catalyst activity, with minimized aromatic ring loss and with minimal formation of popcorn polymer from the reaction effluent.

WHAT DOES CHROMIUM DO FOR US?. What scientist have established is that chromium is involved in glucose metabolism. They are not sure how but they know it does. Insulin appears to be more effective when chromium levels are optimal. Because of its affect on insulin chromium also has an indirect role in carbohydrate, fat and protein metabolism all of which insulin influences.. When chromium is ingested at the same time as vitamin C more chromium enters our blood stream.. Contrary to what the diet and exercise gurus might tell you chromium lll does not promote weight loss nor does it increase lean body mass or decrease body fat. WHAT HAPPENS WHEN WE DONT GET ENOUGH CHROMIUM?. Chromium deficiency is the disorder that too little chromium in the diet produces. This deficiency was first observed in some extreme cases. These cases were hospitalized patients who were being fed intravenously. They developed problems with the way glucose was being managed in their bodies and they started to produce ...

The responses of dairy cattle to chromium (Cr) supplementation reported in the literature suggest that it has the potential to reduce the incidence of both mastitis and ketosis. The effect of Cr supplementation of pasture fed dairy cows in early lactation was studied. Ten lactating Jersey cows fitted with rumen fistula were infused with either Cr-yeast (n=4), casein (n=3) or buffer only (controls; n=3) directly into the abomasum. All cows were subjected to a hyperinsulinaemic euglycaemic clamp. Preliminary results show that there was no effect of Cr supplementation on milk yield, cortisol and b-hydroxy butyrate concentrations and somatic cell counts ...

Ammonium nitrate activated or catalyzed with certain chromium compounds provides an excellent, low cost blowing or expanding agent(s) for many foamable polymers, including polyethylene(s), polystyrene(s), etc.
Very little chromium (,2%) in the form of inorganic compounds is absorbed but may be higher with certain organic formulations (14). Once absorbed, chromium is distributed to various tissues of the body, but appears to be most concentrated in the kidney, muscle, and liver (16). The principal carrier protein for chromium is transferrin, which also plays a critical role in the movement of chromium from blood to LMWCr. It has been suggested that migration of transferrin receptors to the plasma membranes of insulin-insensitive cells after insulin stimulation is the initial step in this process. Transferrin containing the plasma-bound chromium is postulated to bind to the transferrin receptors and is internalized by endocytosis (Figs. 1 and 2). The pH of the internalized vesicle is reduced by ATP-driven proton pumps, chromium is released from transferrin, and the resulting free chromium is postulated to be sequestered by LMWCr (15,17). With this step, chromium is transferred from transferrin to LMWCr, ...

Chromium appears to be the most useful mineral in the prevention of type 2 diabetes. Chromium and niacin are components of glucose tolerance factor, a molecule that improves insulins ability to lower blood sugar levels. Animal studies have shown that chromium deficient diets result in high blood sugar levels. Chromium deficient diets are extremely common: One survey estimated that over 90% of Americans consume less than the so-called "minimum daily intake." Although the best food sources of chromium are mushrooms, brewers yeast, and eggs, chromium supplementation is advisable when a glucose-insulin tolerance test is abnormal. In my experience, the common commercially available 200 microgram quantity is inadequate for either prevention or treatment of type 2 diabetes.. Researchers have shown that 200 micrograms of chromium daily is ineffective in lowering blood sugar in actual type 2 diabetes. But when levels are raised to 1,000 micrograms daily, blood sugar, serum insulin, and cholesterol ...
A high intake of chromium in your diet doesnt cause serious side effects. But you should check with a healthcare provider before taking it. This is vital if youre pregnant or breastfeeding. If you have diabetes, chromium supplements could change how much medicine you need. They may also lower your blood sugar levels. Check your blood sugar levels closely if you start taking them. Chromium supplements may interact with other medicines. Zinc may decrease how well you absorb chromium. Chromium may cause you to need less of your diabetes medicines. These may reduce chromium levels:. ...

Almost anyone is capable of increasing the level of physical activity. While walking is one of the best forms of activity for improving insulin resistance, any activity that creates muscular activity is beneficial. Losing weight, however is not so simple.. Since Insulins primary function is to convert sugar to fat, high levels of insulin promote weight gain. As body weight rises, insulin resistance increases. In response the body produces more insulin, which converts more sugar to fat, and the vicious cycle continues.. Chromium Plus was for formulated to address the causes of insulin resistance in a comprehensive manner. Chromium Polynicotinate is the key ingredient. Chromium is an insulin co-factor, and chromium deficiencies, which are widespread in our society, are indistinguishable from what is called type 2 diabetes. The polynicotinate form is the most bioavailable, meaning that it is the form that is best absorbed and utilized by the body.. Chromium alone will reverse some, but not all ...
Chromium is a naturally occurring element found in rocks, animals, plants, soil, and in volcanic dust and gases. Chromium is present in the environment in several different forms. The most common forms are chromium(0), trivalent (or chromium(III)), and hexavalent (or chromium(VI)).

1614 Early detection of ovarian cancer might improve clinical outcome. We hypothesized that a panel comprised of multiple biomarkers, which individually may not show strong correlation with the disease, may provide higher diagnostic power. To evaluate the diagnostic utility of multimarker panel, we have utilized a novel multianalyte LabMAP™ profiling technology that allows simultaneous measurement of multiple markers. Concentrations of 44 biomarkers (cancer markers, cytokines/chemokines, growth, apoptosis and angiogenic factors) , were measured in sera of patients with early stage ovarian cancer, healthy women, and patients with benign pelvic tumors. Twelve markers, i.e. CA 125, CEA, CA 19-9, kallikrein 8, EGFR, Her2/neu, Cyfra 21-1, MMP-2, MMP-9, IL-6, IL-8, VEGF, EGF, and MCP-1 demonstrated significant differences in serum concentrations between ovarian cancer and control groups. Classification tree analysis of these biomarkers resulted in 94% sensitivity at 97% specificity. The ...

There are a wide variety of body contouring procedures available today. However, they do not always yield the results that patients desire. For instance, liposuction-while it usually produces satisfactory results-can be overdone and leave unnatural-looking dents and contour irregularities. A common solution for this is traditional fat grafting, but this tactic has a high fat resorption rate and often requires multiple treatments. Dr. Renato Calabria has perfected the revolutionary, new technique of using fat grafting with stem cells to resolve these issues. This technique uses advanced technology to produce highly satisfactory results with natural-looking improvements in body contour as well as skin texture ...

Mexicos antitrust agency found America Movil, the mobile-phone carrier controlled by billionaire Carlos Slim, engaged in anti-competitive practices by preventing subscribers to exchange text messages with NII Holdings, according to a preliminary ruling. Under the accord, either government can limit imports of a product from the other country, provided it is shown that the imports of that product will hurt local industry. The takeover bid, announced Friday, would join the worlds No. 1 and No. 2 steel makers, with an almost 10 percent share of global steel production and a market capitalization of close to $40 billion.
The American Society for Testing and Materials was established in 1898 by engineers and scientists who sought solutions for breaks in rail lines. The work of the society led to the standardization of steel production for railroad construction. Today the society is known as ASTM International.

Chromium (symbol Cr and atomic number 24) occurs in the oxidation states 0, +2, +3, and +6 states. Element (0) and divalent chromium, however, are unstable. Chromium (0) immediately produce a thin oxide layer. Divalent chromium is easily oxidized to the trivalent form in air. The trivalent and hexavalent oxidation states are important in industry, which exit in their divalent anions called chromate and dichromate respectively and an chromic anhydride form called chromium trioxide (CrO3) and chromic oxide (Cr2O3). In industrial, chromium trioxide is called chromic acid. The principal uses of chromium are in the metallurgical processing of ferrochromium and other metallurgical products to impart corrosion resistance, chiefly stainless steel. There are applications in chrome plating, anodizing aluminium, and refractory processing of chrome brick. When combined with oxygen together other metallic elements such as lead and potassium, it forms various inorganic pigments. Chromium is used in chemical ...
