Ash leachates and other utility wastes that may enter lakes or streams contain mixtures of chemicals that include several kinds of toxicants. The toxic properties of these mixtures vary with the chemical form and concentration of their constituents. EPRI is developing a general toxicity model (GTM) to simulate environmental conditions in bodies of water where toxicants are present, and to predict the effects of toxicants on aquatic life-forms and ecosystems. To date, scientists have developed analytical methods to measure ambient concentrations of the major species of trace elements (selenium, arsenic, and mercury) and a model to describe the biogeochemical role of selenium. Recent studies of selenium cycling through the aquatic food web support GTM development.
