Total mercury (Hg) concentrations (THg) and stable mercury isotopic compositions were measured in coal samples (n = 61) from major coal producing fields in China. The THg concentrations in coals ranged from 0.05 to 0.78 μg g–1, with a geometric mean of 0.22 μg g–1. Hg isotopic compositions in coals...
