Five physicians radiological assessments of coalworkers simple pneumoconiosis (CWP) in 2600 coalminers at 10 British collieries have been studied in relation to the individuals estimated lifetime (mean 33 years) exposure to respirable coalmine dust. Estimates of exposure were based on 20 years of observations at each colliery. Radiographic classifications were clearly associated with the measures of dust exposure. Important unexplained differences between some of the collieries were disclosed. Among men with similar cumulative dust exposures those with longer exposure time had higher prevalence of CWP. In general there was no evidence that the quartz concentrations experienced (average 5% of mixed dust) affected the probability of developing coalworkers simple pneumoconiosis. Some men reacted unfavourably (two or more steps of change on the 12-point radiological scale) over a 10-year period to coalmine dust with a relatively high quartz content.. ...

The National Institute for Occupational Safety and Health (NIOSH) is offering a series of free, confidential health screenings to coal miners throughout the United States.. The screenings are intended to provide early detection of coal workers pneumoconiosis (CWP), also known as black lung, a serious but preventable occupational lung disease in coal miners caused by breathing respirable coal mine dust.. The health screenings will be provided through the state-of-the-art NIOSH mobile testing unit at convenient community and mine locations.. NIOSH will provide the health screening for these coal miners under its Enhanced Coal Workers Health Surveillance Program. This public health outreach is in response to a well-documented increase in serious disease, and in response to new regulations requiring that health screenings be offered to surface miners.. This years first focus started the week of April 11 and ends on May 20, 2016, in coal mining regions throughout Oklahoma, Arkansas, Texas, ...

Rates of severe coal workers pneumoconiosis - also known as black lung disease - among coal miners have been on the rise recently despite regulations on exposure to dusts associated with mining. Researchers believe the higher rates of more severe lung disease may be due to greater exposure to silica, likely as a byproduct of going after ever-narrowing coal seams that require cutting through more rock to reach. Silica dust is much more toxic to the lungs, but little is known about its contribution to black lung disease at the molecular level, and researchers dont know how silica and coal or other dusts together might interact to influence the development of disease.. A new $750,000 grant from the Alpha Foundation for the Improvement of Mining Safety and Health will support researchers in the University of Illinois at Chicago Mining Education and Research Center working to find out how various mining dusts contribute to lung disease. The center, which is housed in the UIC School of Public ...

Abstract: Background South Africa has one of the largest miner autopsy databases, PATHAUT dating back to 1925. The diagnoses recorded on this database have never been evaluated for coal miners. The objective was to determine the validity of the autopsy diagnoses for coal workers, specifically bronchitis, silicosis, tuberculosis, coal workers pneumoconiosis and emphysema, from 1975 to 1997.

Faced with persistent and emerging health risks in 2016, the National Institute for Occupational Safety and Health (NIOSH) continued its mission to develop and transfer into practice new knowledge about occupational safety and health. Challenges NIOSH faced in 2016 included coal workers pneumoconiosis, or black lung disease. Black lung disease cases reached historic lows in the 1990s after the Coal Mine Health and Safety Act became law in 1969 and was amended in 1977. Recent years, however, have seen rising numbers of current and former coal miners diagnosed with the disease. Other diseases became emerging risks for workers in 2016, including Zika virus and the debilitating lung disease obliterative bronchiolitis, which may be a risk for people who work in the coffee processing industry. Throughout the year, NIOSH translated these and other research priorities into informative communication and research products, promoting occupational safety and health for all workers ...

No man should die from coal mining, be it from a methane explosion, a roof collapse or black lung - coal-miners pneumoconiosis.. The Federal Coal Mine Health and Safety Act of 1969, among other things, set standards to reduce dust and created the Black Lung Disability Trust to compensate miners who contracted this disease.. The law worked. Over time there was a 90 percent reduction in miners with this ailment. What was accepted by some people as an occupational hazard became unacceptable and companies changed their practices.. But since the 1990s, black lung has rebounded, researchers with the National Institute for Occupational Safety and Health say.. The numbers are still well below the level 45 years ago, when the law passed, but the numbers dont matter. The number of incidences must go down until it is eradicated like smallpox.. Progressive massive fibrosis - one form of black lung - is at its highest rate since the early 1970s for miners in West Virginia, Kentucky and Virginia, according ...

GPs are at the forefront in combatting a new epidemic - but its not an infectious disease that has public health experts concerned. An epidemic of silicosis has emerged among workers in the engineered stone industry, bringing into focus the continued risk of lung diseases facing Australian workers across many occupations. As with coal workers pneumoconiosis (CWP), which shocked physicians when it re-emerged among Queensland coal miners a few years ago, it was thought that safe work practices had relegated silicosis to history. The silicosis epidemic among stonemasons in Queensland is a stark reminder of workplace dangers, writes Megan Howe.

This document contains proposed regulations implementing amendments to the Black Lung Benefits Act (BLBA or Act) made by the Patient Protection and Affordable Care Act (ACA). The ACA amended the BLBA in two ways. First, it revived a rebuttable presumption of total disability or death due to pneumoconiosis for certain claims. Second, it reinstituted derivative entitlement to benefits for certain eligible survivors of coal miners whose lifetime benefit claims were awarded because they were totally disabled due to pneumoconiosis. These survivors need not also prove that the miner died due to coal workers' pneumoconiosis. The proposed rules would clarify how the statutory presumption may be invoked and rebutted and the application and scope of the derivative-survivor-entitlement provision. The proposed rules also eliminate several unnecessary or obsolete provisions. ...

(Reuters Health) - Since the 1990s, annual numbers of U.S. coal miners with new, confirmed cases of an advanced form of so-called black lung disease known as progressive massive fibrosis have been steadily rising, according to a new study.

Pneumoconiosis is an irreversible, preventable disease caused by dust inhalation. Although in other countries, by precautions the incidence decreased to 0,3-5%, it is still 10-15% in our country in pneumoconiosis causing occupations.We aimed to describe the characteristics of our 208 pneumoconiosis workers admitted to Istanbul Occupational Disease Hospital. Patient files between 01st Jan 2008 and 31st Dec 2010 are used for the descriptive study. All of the patients were male with 38,82±13 years of age. The most common workplace was Gaziosmanpasa with 27 cases. The mostly seen works were denim sandblasting, dental technicians, coal mining and casting (%50,5,%12,%6,7,%4,8). The most exposure material was silicium (86,5%). Mean exposure time was 9,9±8,9 years. Profusion according to the ILO classification was in the table. In 37 cases, there was an A opacity and B opacity in 28. The mean FEV1% was 67,27±23,3, FVC%73,78±20,86, FEV1/FVC%85,1±16 and KcO 102,74±28,1. The period between exposure ...

Occupational lung diseases are occupational diseases affecting the respiratory system, including occupational asthma, black lung disease (coalworkers pneumoconiosis), chronic obstructive pulmonary disease (COPD), mesothelioma, and silicosis. Infectious lung diseases can also be acquired in an occupational context. Exposure to substances like flock and silica can cause fibrosing lung disease, whereas exposure to carcinogens like asbestos and beryllium can cause lung cancer. Occupational cases of interstitial lung disease may be misdiagnosed as COPD, idiopathic pulmonary fibrosis, or a myriad of other diseases; leading to a delay in identification of the causative agent. Asbestosis is a fibrosing interstitial lung disease caused by exposure to forms of the mineral asbestos. Asthma is a respiratory disease that can begin or worsen due to exposure at work and is characterized by episodic narrowing of the respiratory tract. Occupational asthma has a variety of causes, including sensitization to a ...

In Britain data come mainly from the Pneumoconiosis Field Research (PFR) programme conducted by the Institute of Occupational Medicine.6-12 This was based on 24 collieries. At an initial survey during 1953-58 more than 30 000 miners were examined and repeat surveys were subsequently carried out at approximately five yearly intervals. After the third survey conducted during 1963-68 examinations were discontinued at 14 of the 24 collieries, but all 24 were again included in a follow up survey carried out during 1974-80. This focused on a sample of 17 738 miners examined in the first survey (all those with pneumoconiosis and half of the remainder), and aimed to re-examine all survivors, whether or not they were still employed in the coal industry. Information collected at the surveys included details of smoking habits, occupational history and symptoms (elicited by questionnaires), chest radiographs and measurements of lung function (lung function was only assessed in the second and later surveys). ...

Record contained sufficient evidence to support ALJs finding that claimant was totally disabled by pneumoconiosis arising out of his coal mining employment based on his second application for Black Lung Disease benefits, after his first application had been denied by reason of abandonment. Employer conceded that claimant had demonstrated change in his condition of entitlement in that he was now totally disabled, and ALJ could properly find that claimant had labored for at least 15 years in surface mining conditions, which included work in presence of coal and rock dust, that was substantially similar to underground mining conditions, and that employer had failed to rebut resultant 15-year presumption that claimant was totally disabled due to pneumoconiosis. Fact that claimant had extensive history of cigarette smoking, or that record contained medical evidence that was in equipoise on issue regarding presence of totally disabling respiratory impairment did not require different result ...

An ILO chest x-ray uses a standard classification system for identifying pneumoconiosis (occupational lung disease - silicosis is one type).. Its important that a specially qualified radiologist reviews the ILO chest x-ray. To qualify, the radiologist must pass the B reader examination run by the National Institute for Occupational Safety and Health (NIOSH). This certifies them to classify chest x-rays using the ILO system.. Using a B reader has become established practice for detecting early x-ray changes. For a list of qualified Australian B readers, see the NIOSH website (link below). At the time this page was last updated, the NIOSH site listed one B reader in Victoria, at MIA Radiology (link below). There may be other B readers not known to WorkSafe, or who practise outside of Victoria, who can perform the testing.. ...

Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust. It is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs.It is a type of pneumoconiosis. Silicosis (particularly the acute form) is characterized by shortness of breath, cough, fever, and cyanosis (bluish skin). It may often be misdiagnosed as. ...

Analysis of Data and Probabilities The International Labor Organization (ILO) classification of roentgenograms of the pneumoconioses provides a method for recording abnormalities of the lungs and pleura resulting from the inhalation of inorganic dusts. First developed in the 1950s, and subsequently modified, it allows classification of the roentgenographic changes due to asbestosis as well as […]. ...

Inhalation of this dust could cause acute nonspecific irritant bronchoconstriction particularly in those with twitchy lungs. It could cause subacute bronchitis lasting weeks or, eventually, chronic bronchitis of the type reported in coal miners. It might cause simple siliceous pneumoconiosis (mainly silicates) as described in Bedouin Arab females and others exposed to desert sands, and finally, after years of intense exposure, it could cause the scarring of silicosis.. It is interesting that there has been little acute respiratory disease which can be attributed to inhalation of the ash. Twenty hospitals have been monitored. Those with very heavy exposure in the Moses Lake-Ritzville area had three times the usual emergency room attendances, with some increased admissions. However, physicians offices were closed at the time so it is difficult to assess the relevance of these data. Certainly, patients with asthma and COPD have not crowded into the hospital emergency rooms as they usually do when ...

Coal workers are at risk of developing occupational lung diseases from inhaling hazardous dust. As there is no known cure, early detection helps identify individuals who need treatment and to be removed from risk of further exposure. Tabled 5 December 2019.

This Work-Related Lung Disease (WoRLD) Surveillance Report is the sixth in a series of occupational respiratory disease surveillance reports (see page iv) produced by the National Institute for Occupational Safety and Health (NIOSH).

The mortality of a cohort of 1487 male patients with silicosis in a population-based register followed up from 1980 to 1986 was evaluated with reference to the mortality rates of the general male population. A striking excess of deaths from all causes (observed 368, standardized mortality ratio, SMR 3.00) was noted. Seventy-four percent of the deaths were due to respiratory conditions and complications directly or indirectly related to silicosis. The risk of death was especially higher than expected in younger patients under 45 years of age. Patients with simple silicosis of profusion category 1 did not appear to be at any increased risk of death relative to the general population, but increasing excesses of death were associated with greater extent of simple and conglomerate disease. These increased mortality risks were observed in tuberculosis-free patients as well as in those who never smoked. For the same extent of silicotic disease, the risk of death was higher if tuberculosis occurred. ...

The smaller a particle is, the deeper into the pulmonary system it penetrates. Respirable dust, the dust we inhale is made up of particles smaller than 5 thousandths of a millimeter (5 μm). Because the particles are so small, they can penetrate into the deepest parts of the pulmonary system where the air moves too slowly to be able to breathe them out again. The lungs way of protecting themselves is to wrap the foreign particles in nodules of connective tissue, which, in time, leads to pneumoconiosis or COPD (Chronic Obstructive Pulmonary Disease). Some types of particles, such as silica and asbestos dust, cannot be broken down by the body and are also sharp, which is why they continue to cause damage long after they have become lodged in the lungs.. The best protection is to remove dust at the source and never allow it to reach the air. Dustcontrol has developed suction castings for most handheld and stationary machine, and also produces tailor-made suction castings.. ...

Respirable particles of high-percentage silica content from anthracite and bituminous coal mine dust samples were analyzed for aluminosilicate clay surface coating, by measuring silicon and aluminum X-ray spectra using scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDS). Silicon and aluminum elemental ratios were determined with incident electron energies of 20 and 5 keV to reveal whether surface occlusion was present. Some 20 respirable-sized, non-agglomerated particles with silicon fraction of signal of 75% or more (for elements above sodium) were analyzed for each of 12 coal mine dust samples. Mine dust samples were from U.S. anthracite and bituminous coal mining regions involved in epidemiological studies of the U.S. National Study of Coal Workers Pneumoconiosis. Some particles of high-percentage silica content exhibited a decrease in the ratio of silicon-to-aluminum K-alpha line intensities with decreasing electron beam accelerating voltage, consistent with aluminosilicate clay

Particle sizing by laser diffraction provides a prospective method for real-time detection of weight and size information of coal mine dust. Quickness, accuracy and ability to measure total and respirable dust weighs are some of the basic requirements for inversion method of the coal mine dust transducer. This paper presents a quick inversion scheme that can be referred to as pattern recognition of laser diffraction field. Single-chip computer system simulation results show that this method not only furnishes excellent estimates of both total and respirable dust weights in a very short time but also features high anti- noise ability and stability ...

GRAND JUNCTION - New coal mining rules that go into effect in August are designed to decrease the hundreds of deaths that still occur from black lung disease. But the costly new rules are not popular with all miners and mine operators.. Officials from the Mine Safety and Health Administration spent more than five hours Thursday explaining the new regulations to dozens of coal mine operators and miners. The gathering in Grand Junction was the last of a series of seven meetings held around the country in states with coal mines.. We still see miners getting black lung, said Kevin Stricklan, administrator of Coal Mine Safety and Health for MSHA. Two hundred and eighty people die every year from respirable illness. Since 1968, over 76,000 miners have died.. To drop the numbers of what is medically called pneumoconiosis and to cut the $45 billion paid out in federal compensation, MSHA is instituting the first changes to coal mine dust rules since 1969..

In the preamble to MSHAs final rule titled Lowering Miners Exposure to Respirable Coal Mine Dust, Including Continuous Personal Dust Monitors (CPDMs) published in 2014, MSHA committed to take the lead in conducting a retrospective study of the rule to assess whether it achieves MSHAs goals of reducing and maintaining respirable coal mine dust levels to protect miners from black lung, a disabling occupational lung disease. However, due to the latency between exposure and disease, MSHA likely will not be able to evaluate the health effects of the rule for a decade or more. In this Request for Information, MSHA is soliciting stakeholder comments, data, and information to assist the Agency in developing the framework for this study to assess the impact of the Dust rule on lowering coal miners exposures to respirable coal mine dust to improve miners health. In addition, as part of the Agencys ongoing effort to provide compliance and technical assistance to mine operators and miners, MSHA is ...

Introduction Pulmonary tuberculosis (TB) is a disease which is both curable and preventable, with recognised complications such loss of lung function and progressive massive fibrosis (PMF). It is a major cause of pulmonary disability and mortality in the South Africa mining industry. Tuberculosis has a high social and economic cost, both for the individual concerned and for the industry as a whole. However, notwithstanding the extensive literature on TB in the mining industry, given the size and economic importance of coal mining in South Africa, there is surprisingly scanty information available on TB and other occupational lung diseases in coal mines. A strong correlation was reported in Canada, the USA and China between coal usage and TB. This highlights the possibility of the direct impact of coal usage on TB. Although black miners have historically done jobs with the highest exposure in the coal mining industry, there have been remarkably few studies reporting the prevalence of TB and the ...

RIN: 1219-AB64). (i) Cost-benefit analysis. MSHA estimates that the first-year cost of the final rule will be $61 million and the annualized cost of the final rule at a 7 percent discount rate will be $28.1 million. MSHA estimates that the net benefits of the final rule are positive, with annualized net benefits of $12.1 million at a discount rate of 3 percent, and negative with annualized net benefits of -$8.1 million at a discount rate of 7 percent. Under the Federal Mine Safety and Health Act, MSHA is not required to use estimates of net benefits as the basis for its regulatory decisions. The net benefits at both the 3 and 7 percent discount rates do not include the benefits associated with sampling over a full-shift using the CPDM as well as several other provisions of the final rule. These provisions, although not quantified, will significantly reduce coal mine dust exposures and the incidences of other lung disease and significantly increase benefits.. (ii) Agency actions relevant to the ...

In an extraordinary rebuke to a doctor at one of Americas top hospitals, the U.S. Department of Labor has informed about 1,100 coal miners that their claims for black lung benefits may have been wrongly denied because of the actions of a powerful physician at the Johns Hopkins Medical Institutions, the departments deputy secretary told senators Tuesday.. That doctor, Paul S. Wheeler, systematically found that miners did not have black lung when, in fact, many of them did. Medical opinions by the doctor should be assumed not to be credible, senators and affected miners were told.. The governments outreach and the Senate hearing were both prompted by a series of stories released last year by The Center for Public Integrity in partnership with ABC News.. Miners who get black lung, a debilitating and incurable disease caused by breathing in coal dust, are entitled by federal law to compensation, often from their former employer. But the series, which was the result of a yearlong investigation, ...

Firstly, under the ground there is no light at all. It is very unnatural to men and women to live and work with no access to the suns light. People require the light to function perfectly and to develop correctly. It is apparent, that the coal miners posses some special torches which make their work better but it is just a single ray of unnatural light, anything more.. Secondly, when the coal miners operate very deep the climate of surroundings is very raised, perhaps 30 Celsius degrees. It is the climate where it is very difficult to operate and think plainly. http://www.minemaster.eu/toolsthe coal mines appear spring of H2O which make the work harder. In these situations, the miners might wear special shoes which protect their feet against liquid. The pro boots are normally very heavy so the coal miners do not work in pleasant environment.. ...

When a proper detailed history, clinical examination, chest X ray and sputum analysis does not yield a definite diagnosis for the cause of chronic cough, bronchoscopy is indicated. We did a descriptive study among 39 patients who underwent bronchoscopic evaluation for chronic cough (more than 4 weeks) with normal chest X ray and without a prior definitive diagnosis. 16 out of 39 patients were diagnosed to have tuberculosis on analysis of the bronchial washings. 6 patients (66.67%) with left upper lobe mucosal inflammation were AFB smear positive. 5 patients ( 31.25 %) with normal bronchoscopy were AFB smear positive.4 out of 5 patients (80 %) with bilateral upper lobe mucosal inflammation were AFB smear positive. Pulmonary tuberculosis can present with chronic non productive cough and normal chest X ray. Bronchoscopy is helpful in establishing the diagnosis. When bronchoscopy shows bilateral or unilateral upper lobe bronchial mucosal inflammation, possibility of tuberculosis is high. ...

Objectives Whether nonpneumoconiotic silica-exposed coal miners develop radiologically recognizable pleural changes was studied.. Methods In a retrospective follow-up study, the oldest and the most recent chest X-rays of 765 workers with a profusion category lower than 1/0 according to the International Labour Office were read.. Results Altogether 720 (94.1%) workers had no abnormalities, and 45 (5.9%) showed some pleural alteration in the first X-ray. In 43 (6%) of the 720 with no initial abnormalities, some pleural change was detected in the last X-ray. There was a statistical difference (P=0.022) according to silica exposure category [low: 5 (2.4%); medium: 8 (6%); high: 30 (8%)]. The relative risk for any pleural alteration was significantly increased in relation to the silica-exposed group [medium: odds ratio (OR) 5.72, 95% confidence interval (95% CI) 1.4-23.5, P=0.016; high: OR 7.62, 95% CI 2.1-27.2, P=0.002] and to rib alterations (OR 3.74, 95% CI 1.4-9.7, P=0.007).

A 51-year-old electrician who has worked in underground coal mines is the latest to be diagnosed with coal miners pneumoconiosis.

ARLINGTON, Va. - Eight months after implementation of the final rule to prevent black lung disease by lowering miners exposure to harmful coal dust, sampling by mine operators and Mine Safety and Health Administration inspectors indicates that compliance with the rules tougher requirements is highly achievable.

WASHINGTON, D.C. -U.S. Sen. Sherrod Brown (D-OH), along with U.S. Sens. Joe Manchin (D-WV), Tim Kaine (D-VA), Mark Warner (D-VA) and Bob Casey (D-PA), recently urged Secretary of Labor Alexander Acosta to protect mine safety and miners health by protecting a recent rule aimed at limiting miners exposure to respirable coal mine dust. The Senators letter comes after the rule was listed among a number of rules to be re-examined for elimination. The rule was aimed at reducing work-related illnesses that miners face like black lung disease. Brown applauded the Department of Labors effort to limit coal dust exposure when it was announced in 2014.. Given this increase in black lung disease and the devastating impact that this disease has on coal miners and their families, we believe that it is critical that we maintain this rule, wrote the Senators in the letter. Claims that the Respirable Dust Rule is unnecessary, imposes a costly burden, or provides little to no benefit to society ignore the ...

Johns Hopkins Medical Institutions received millions of dollars from coal companies for reading chest X-rays yet rarely confirming that miners are suffering from black lung disease. This famed teaching hospital has been the subject of an investigation for the past year by ABC News and the Center for Public Integrity after miners were told they didnt have black lung and therefore could not collect benefits.. At the center of the controversy is Dr. Paul Wheeler, age 78, who is the leader of the medical unit that reads the miners chest X-rays and CT scans on behalf of the coal companies. Dr. Wheeler and his team of radiologists issue reports based on what they determine the X-rays show. Those reports are then used to confirm or deny whether the miner has black lung disease.. Coal companies have relied on the expertise and stellar reputation of Johns Hopkins for the past 40 years. Even though the doctors read the chest films as part of their regular duties, the university charges the coal ...

X-ray powder diffraction (XRD) is a well-established tool in the study of hydrothermal systems, as it allows for the identification and quantification of mineral assemblages. Through the quantification of alteration mineral assemblages geologists can characterize the geometry of a deposit or geothermal system and draw inferences regarding the fluid evolution and environmental conditions of deposition (e.g., pH, T). Traditionally, XRD devices have largely been restricted to laboratories; however, advances in XRD sample holders and X-ray sources have allowed for the development of portable XRD (pXRD) devices. This paper assesses the validity of the Olympus Terra pXRD instrument for qualitative and quantitative studies of hydrothermal systems through comparisons with data from laboratory XRD (Empyrean II diffractometer) and XRF techniques for both synthetic mixtures of natural minerals and a variety of samples from the Kulumadau epithermal gold deposit, Woodlark Island, Papua New Guinea. ...

1. Coal dust is a problem wherever there are coal mines or wherever coal is transported through residential areas and cities. That and other particulate matter released during the different processes involving coal can cause a number of health problems, some of them fatal, if in excess.. Very small particulate matter carried by the air can enter our lungs and affect our health, sometimes leading to hospitalisation. If the people breathing in this air already have lung problems, they are going to bear the brunt of it. Other health problems include black lung disease (or coalworkers pneumoconiosis) among miners and treatment plant workers, congestive heart failure, asthma attacks, chronic bronchitis and reduce life expectancy. Young children are also very susceptible to chronic lung problems. It has been found that coal trains passing through a citys outskirts can raise particulate air pollution by as much as 120% in many cases. Also, in general, coal trains were found to cause much more ...

Coal worker, Ashiky, 22, in Jharia coal mine in Jharkhand. Coal workers are some of the most severely affected from the ill effects of coal.

Working with coal, whether as a miner or in other ways, results in an accumulation of coal or other dust in macrophages in and around respiratory bronchioles. Mild dilatation of respiratory bronchioles results, probably from atrophy of muscle. The lesion resembles centrilobular emphysema but differs in that the enlarged spaces are smaller and more regular, and inflammation of bronchioles is not apparent. Thus, the lesion is primarily distensive rather than destructive. The anatomic lesion is usually equated with a chest radiograph that shows small nodular densities, although the complete correlation has not been proved. The condition, also referred to as black lung, has been considered to cause severe disability. Contemporary evidence, however, suggests that simple coal pneumoconiosis causes only minor impairment of pulmonary function. When coal miners have severe chronic airflow obstruction, it is usually due to other forms of emphysema, notably tobacco-related centrilobular emphysema. Other ...

Occupational exposure is the most common cause of asbestosis, but the condition also strikes people who inhale asbestos fiber or who are exposed to wasteproducts from plants near their homes. Family members can develop the diseaseas a result of inhaling particles of asbestos dust that cling to workers clothes.. It is rare for asbestosis to develop in anyone who hasnt been exposed to large amounts of asbestos on a regular basis for at least 10 years. Symptoms ofthe disease do not usually appear until 15-20 years after initial exposure toasbestos.. The first symptom of asbestosis is usually shortness of breath following exercise or other physical activity. The early stages of the disease are also characterized by a dry cough and a generalized feeling of illness.. As the disease progresses and lung damage increases, shortness of breath occurs even when the patient is at rest. Recurrent respiratory infections and coughing up blood are common. So is swelling of the feet, ankles, or hands. Other ...

Anthracosis is a form of pneumoconiosis seen in coal workers, although other environmental factors such as cigarette smoke, air pollution and biomass fuels used extensively for cooking and home heating are also known to cause anthracosis.1-6 The terms hut lung or domestically acquired particulate lung disease have been used to describe the condition.7 A diagnostic feature in anthracosis is the black-colored deposits along the airway or lymph nodes. Problems caused by chronic exposure to biomass smoke and other particulates, such as dust or silicates from food grinding, are becoming more relevant in the western world due to immigration.7,8 Individuals may develop both physical and radiologic abnormalities of the lung presenting as chronic obstructive or fibrotic lung disease due to chronic exposure to smoke and particulates. Recent estimates attribute 1.5 to 2 million deaths per year worldwide to indoor air pollution, most of them (1 million) occurring in children younger than 5 years due to ...

Occupational lung diseases, such as silicosis, occupational asthma and asbestosis, are caused by breathing in harmful substances and irritants like silica, chemical fumes and asbestos.

Occupational lung diseases are lung problems that are made worse in certain work environments. They are caused by long-term exposure to certain irritants that are breathed into the lungs. These lung diseases may have lasting effects, even after the exposure ends.

The novel coronavirus has been rapidly spreading worldwide, affecting everyones lives more than wed have expected - from stress and anxiety, having to practice social distancing and therefore isolate inside the house to the illness itself. And its with good reason that most people are concerned about it, as the disease can have serious complications and even become deadly for the ones who find themselves being in the groups with a high risk.. For former industrial workers, the risks of developing severe complications if infected with COVID-19 are high, especially if they have been exposed to various toxins that could have potentially damaged their lungs and left them with respiratory diseases. One of the most common work-related diseases is asthma, the occupational development of it accounting for 15% of adult on-set cases, followed by COPD that can develop from the inhalation of fumes, dust, and gasses. Industrial workers are also at risk of developing pneumoconiosis as a result of exposure ...
