Environmental Health - Toxic Substances Hydrology Program
Research is documenting with increasing frequency that many chemical and microbial constituents that have not historically been considered as contaminants are present in the environment on a global scale. These "emerging contaminants" or "contaminants of emerging concern" are commonly derived from municipal, agricultural, and industrial wastewater sources and pathways. These newly recognized contaminants represent a shift in traditional thinking as many are produced industrially yet are dispersed to the environment from domestic, commercial, and industrial uses.
The major goal of the Contaminants of Emerging Concern in the Environment Investigation is to provide information on these compounds for evaluation of their potential threat to environmental and human health. To accomplish this goal, the research activities of this project are to: (1) develop analytical methods to measure chemicals and microorganisms or their genes in a variety of matrices (e.g. water, sediment, waste) down to trace levels, (2) determine the environmental occurrence of these potential contaminants, (3) characterize the myriad of sources and source pathways that determine contaminant release to the environment, (4) define and quantify processes that determine their transport and fate through the environment, and (5) identify potential ecologic effects from exposure to these chemicals or microorganisms. Project research on contaminants of emerging concern is being conducted within these five areas. The following links provide more detailed information.
