ENVIRONMENTAL CONTAMINATION BY LEAD AND OTHER HEAVY METALS. VOLUME 2. ECOSYSTEM ANALYSIS

A Metals Task Force attempts to understand and characterize the sources, transport processes, availability, fate, and effects of lead and other heavy metals in the environment. The study investigated an 86-square-mile ecosystem based on a watershed located in east-central Illinois. The watershed is separated into two major compartments on the basis of land use: a 74-square-mile rural, agricultural compartment and a 12-square-mile urban compartment. To establish the potential magnitude to lead accumulation an input-output analysis was initiated early in the research program. This analysis compares major lead inputs to the ecosystem and to the various compartments with major outputs. A model describing the ecosystem inputs, outputs, transports, and accumulations has been developed.
