Título Rate of malignant tumor mortality among coal burning power plant workers occupationally exposed to arsenic
Información bibliográfica 1980, Vol.24, No.3, p.278-284. Illus. 18 ref.
Resumen Retrospective study of mortality patterns among 88 male workers in a power station firing high-arsenic coal and 159 in 3 power stations firing coal with arsenic concentrations of an order of magnitude lower, who had died up to 18 years prior to the study. Among those who died before the age of 60 years, 38% of the exposed group died of cancer against 23% in the control group; in those who died after the age of 60 years the malignancy rates were 51% and 43% respectively. The absolute increase in tumor mortality rates was not significant; however, the higher incidence of malignant deaths in younger age groups and the shorter exposure times were statistically significant (p<0.05 in both cases). Coal combustion products contain micro-quantities of numerous biologically active elements, but the arsenic content of coal (950-1500g/t) justifies the suspicion of a link between specific tumour mortality and exposure to high levels of arsenic.
