Despite increasingly stringent regulatory controls, some toxic substances that occur in trace concentrations in the environment, such as Dioxins, PCBs, phthlates and its metabolites, PDBEs, organotins, organochlorine pesticides, and heavy metals, may present serious health effects to human and succeeding generations. The research center is dedicated to study the monitoring technology, toxicity, health effects, environmental and occupational impacts associated with the environmental trace toxic substances.
