Abstract
Photoactivation analysis is used for the determination of heavy metals in water and humic substances. Isolated humic acids serve as a carrie r of environmental pollutants. The investigation of the drinking water catchment area in the middle German conurbation Leipzig/Halle shows i t to be endangered from old neglected deposits of toxic wastes (chemic al factory destroyed during World War II). Elevated concentrations of the elements zinc, cadmium, lead, and mercury in humic acids from surf ace waters were found.
