A detailed study of the analysis of cadmium, copper, iron, nickel, lead and zinc content in bituminous coals from Pennsylvania and Utah is made including an analytical procedure. The metal content of coal from a Pennsylvania mine having a high incidence of Coal Workers' Pneumoconiosis (CWP) is found to be higher than that of a sample of coal from a Utah mine of low disease incidence. The cadmium content is found to be the same in both coals. The present investigation also deals with some observations concerning interferences associated with coal analysis using atomic absorption spectrophotometric methods. The significance of data is discussed with regard to the change in metal levels found in coal miners' lungs.
