Site-specific data, including chemical concentrations in sediments, interstitial water, surface water, fish, shellfish and other benthic biota, were collected and evaluated, determining potential risks to human and ecological receptors, and identifying remedial strategies for cleanup.

Examined dietary habits of potentially affected villages, provided data on measured metal concentrations in common food items, drinking and bathing water, and assessed exposure activities that bring villagers into direct contact with mine tailings in soils and sediment.

A 10-year national monitoring program to assess temporal and spatial concentrations of the biocide tributyltin in sediments, water, and biota in estuarine and freshwater environments.
