In Environmental Sciences Division annual progress report for period ending September 30, 1973. The Toxic Materials in the Environment project is concerned primarily with sources, cycling, and fate of trace elements in aquatic and terrestrial ecosystems. This project is currently addressing three major research areas: trace elements in soils and sediments, biological transport of trace elements, and environ mental reconnaissance and cycling. Results to date are summarized on characterization of cadmium and nickel in river sediments; evaluation of organic matter and sequioxides of iron and aluminum on the absorption of trace elements by clay minerals; the effects of the environmental factors, temperature, and concentration on the accumulation of methylmercury by fish populations; and the establishment of forest stand and input/output budgets of cadmium, lead, zinc, and several other trace elements for Walker Branch Watershed.
