✦ Synopsis

Tkuse

of coal as a domestic and industrial fuel, and as an energy source increases annually; Besides concern about public health from volatile materials released into the atmosphere, environmental pollution by&e elements, especially mercury, is a problem. It appears that increased levels of mercury found along the jet stream belt in the Northern Hemisphere are the result of this type of industriai and domestie activity [I], so that analysis. of environmental samples for mercury will continue to be of interest.'This communication describes a wet oxidation method that can be used to determine mercury in samples, such as coal, that have a high percentage of organic matter. The technique minimizes possible errors from atmospheric mercury contamination, incomplete sample oxidation and retention of mercury by acidinsoluble matter.
