Components of Coal Mine Dust Exposure and the Occurrence of Prestages of Pneumoconiosis

A systematic review of occupational exposure to coal dust and the risk of interstitial lung diseases

“…The results of the included studies are summarized in Table 1 . Seven studies were based in the UK;[ 15 – 20 , 22 ] one was performed in Germany [ 21 ] and one in USA. [ 23 ] The included studies originated mostly from open cohorts of mineworkers employed in specific mines followed several years with exposure measurements and chest X-rays.…”

“…[ 23 ] The included studies originated mostly from open cohorts of mineworkers employed in specific mines followed several years with exposure measurements and chest X-rays. The performed analyses were either cross-sectional,[ 15 , 17 – 20 , 22 ] longitudinal with average follow-up periods between 9.3 [ 21 ] and 21 years [ 23 ] or nested case control studies. [ 16 , 18 ] The study populations varied between 21 [ 16 ] and 8829 [ 21 , 23 ] (median number of participants 371).…”

Exposure assessment for nitrogen oxides and carbon monoxide in German hard coal mining

“…Estimating average and cumulative exposures to nitrogen oxides An inception cohort of 1,369 miners from two German coal mines was assembled to study pneumoconiosis risks (Morfeld et al 1997a(Morfeld et al , b, 2002 and lung function deWcits (Büchte et al 2004Büchte 2007). The coal miners started work underground between 1974 and 1979 and were followed-up in lung function parameter changes (FEV1, FVC) until 1998.…”

“…The measurement campaign is accompanied by an epidemiological study investigating possible health eVects on the airways. The analysis will be performed within an extended follow-up starting in 1974 of a longitudinal investigation into pneumoconiosis risks and lung function changes in German coal miners (Morfeld et al 1997a(Morfeld et al , b, 2002Büchte et al 2004Büchte et al , 2007.…”
