Targeted Toxics Studies

Targeted toxics studies are short-term focused inquiries to better understand and reduce toxic chemicals in the environment. Toxics Studies scientists usually work for other agencies or offices/ programs within the Department of Ecology as consultants.

Water Cleanup Plan Studies for Toxics determine the amount of loading of a chemical that a water body can receive and still meet water quality standards.

Contaminant Characterization Studies describe the types of toxic chemicals and general extent of contamination specific to a certain waterbody or other place in the environment.

Stormwater Monitoring for Toxics includes studies on polluted runoff and its contribution to water quality.

Monitoring for Emerging Contaminants studies of chemicals of concern from little understood or rarely studied sources, such as pharmaceuticals in wastewater and runoff from roofing materials.

Assessments of Methods for Monitoring Toxics

Sampling and analytical methods for measuring toxic chemicals are sometimes evaluated for relevancy of use. Evaluated methods include both new and established methods. Examples include:

Quality Assurance Project Plan: PCB Method Comparison of High Resolution and Homolog Analysis describes a comparison study of three commonly used methods for detecting polychlorinated biphenyls (PCBs) to find an alternative to the limited Aroclors method.

Integrated Ambient Monitoring Pilot Report: Potential Causes for Impairment of Rainbow Trout Early Lifestages and Loss of Benthic Biodiversity in Indian Creek used rainbow trout eggs placed in an urban stream to experience a realistic environmental exposure to the full spectrum of toxic chemicals present. Passive samplers deployed alongside the trout provided a list of pollutants potentially responsible for toxic effects.
