The goal of our research is to link chemical and physiological interactions within metal contaminated aquatic ecosystems to alterations at several levels of biological organization. As such, our research draws on the fields of chemistry, toxicology, physiology, cellular/molecular biology and ecology to understand the fate and effects of pollutants in aquatic ecosystems. In our work we try to understand what factors control the accumulation and detoxification of metals in invertebrate prey and how these factors relate to metal toxicity and trophic transfer.  Current activities are aimed at understanding patterns in metal accumulation and toxicity in aquatic invertebrates inhabiting the waterways surrounding Staten Island. Future studies may address similar questions with terrestrial invertebrates.
