摘要

Studies of biological activity within the litter horizons of a watershed contaminated by emissions from a lead-ore processing complex focused on the litter-arthropod food chain as a means of detecting perturbations in a heavy-metal contaminated ecosystem. Both point sources (smelter stack emissions) and fugitive sources (ore-handling processes, yard dusts, and exposed concentrate piles) contributed to the Pb. Zn, Cu, and Cd levels in the study area (Crooked Creek Watershed, Iron County, Missouri, 37°38 N Lat., 91°07* Long.). Characterization of arthropod food base and habitat was accomplished by critical examination of litter mass, heavy metal and macronutrient content, cation exchange capacity, and pH.
