Two soft coals obtained from mines in which workers had high and low incidences of coal worker's pneumoconiosis are leached with aqueous base and acid to remove acidic and basic components. Results indicate that humic substances similar to those found in soil are present in the coal samples. Differences in the quantity of material removed and its metal-binding and enzyme inhibitory activity are related to disease incidence.
