Statistical analyses of coal seam parameters and airborne respirable dust measurements indicate a likely causal relationship between seam type and respirable dust. Low-ash high-volatile coal seams were associated with higher airborne respirable dust levels. A negative linear correlation significant at the 95-pct confidence level was observed
4 Over the range of coal chlorine levels considered 0.110.44 no relationship was apparent between the coal chlorine content and the mercury retention in the dust. 5 A short series of speciation measurements indicated that over 80 of the vapour phase Hg was present in the oxidised form Hg 2 for the highest chlorine content coal

Results The study was performed in 19 companies with 232 workers aged between 20 and 73 years. The average concentration of particulate matter in the 209 carried out monitoring was 3.4 3 4 mgm3. The risk level from exposure to coal dust was found in the 70.8 148 monitoring and 20.6 43 on severe level with average of 4.9 4.9 mgm3
Logistic model fitting indicated that between 2 and 12 of miners exposed to a 2-mgm3 dust environment in bituminous coal mines would be expected to have Category 2 or greater CWP after a 40-yr working life PMF would be expected for between 1.3 and 6.7. The risks for anthracite miners appeared to be greater
A number of reports on the prevalence of coal workers pneumoconiosis in U.S. coal miners have been published yet very little is known about the relationship between dust exposure and
Some aspects of the relationship between dust exposure and lung function in coal miners with and without coal workers pneumoconiosis CWP were studied. Methods Dust levels in the working place varied between 0.6-8.0 mgm3 with 2-13 silica content. Lung function tests were performed in all miners n615 in one underground coal mine
The research objects are 31 provinces in mainland China. According to the food output the 31 provinces are divided into 13 main food production areas 11 food balance areas and 7 main food sale areas .In 2015 food production in the main food production areas the food balance areas and the main food sale areas respectively accounted for 76.2 18.5 and 5.3 of the national total
After adjusting for age smoking and body mass index risk of IHD mortality increased at higher levels of coal dust exposure. Mortality risk was also associated with coal rank region. Conclusion. There was an increased risk of mortality from IHD associated with cumulative exposure to coal dust and with coal rank
2018-10-1- Study on the dose-response relationship between respirable coal dust and pneumoconiosis
2013-7-15The analyses of measured real-time dust data showed a clear relationship between the average dust levels and the frequency of occurrence of peak dust levels. The study demonstrated a clear method of using real-time dust data for assessing exposure. The average measured section intake dust level was 0.80 mgm3 and 60 of the
Dust and fumes are complex mixtures of airborne gases and fine particles present in all environments inhabited by people. This study investigated the relationship between occupational dust exposure levels and mental health problems such as depression or anxiety fatigue and insomnia or sleep disturbance. We analyed data from the third and fourth Korean Working Conditions Survey KWCS
