Environmental Chemistry

Overview

processing environmental chemistry samples

Scientists are conducting research to identify and understand the potential harmful effects that emerging chemicals of concern have on representative marine organisms and humans. Cutting edge laboratory methods and equipment are used to study “new” pesticides, flame retardants, pharmaceuticals and personal care products. Analytical methods are developed and improved to determine the concentrations of these contaminants in the environment. Additional experiments will include mesocosm studies that allow scientists to measure effects in sentinel species. Learn more about toxic contaminants research at the HML »

Background

Urbanized estuarine watersheds are well-documented to have elevated contaminant levels in their sediments, water and associated biota. The difficulty in making sound assessments on the distribution and bioeffects of these contaminants comes from a lack of detailed understanding of chemical and toxicological interactions in a very complex environment. Many contaminants entering the estuary are not routinely included as analytes in existing monitoring programs because of the lack of robust analytical methods for their detection. Consequently, any risk to estuarine biota and⁄or human health associated with these chemical contaminants cannot be evaluated.

The objectives of the Environmental Chemistry Core include the following:

  1. Build capacity within NOAA for the development of analytical methods for the detection and quantification of emerging contaminants of concern in the estuarine⁄marine environment;
  2. Provide technical support and act as a resource to Hollings Marine Laboratory, NOAA, and the wider scientific community in the development of analytical methods for the detection and quantification of emerging contaminants of concern; and
  3. Coordinate emerging contaminant analytical methods development and provide analytical support for Oceans and Human Health research partners (Monitoring and Assessment Core; Seafood Quality and Risks, Emerging Contaminants Research).
