Development of a standard operating procedure for the collection of pyrethroids in water and sediment matrices. U.S. Geological Survey, Washington, DC.
Impact/Purpose:
The loss of pyrethroid insecticides during sampling can confound the interpretation of analytical and toxicity test results. Sampling method, container material and water composition have a significant influence on the association of pyrethroids to container walls, which can be as high as 50 percent. Sampling method; sampling and laboratory container material; container size; storage conditions; and sample handling procedures have been found by researchers to have significant influences on the losses of pesticides on container walls. This project determined optimum sampling and testing procedures and disseminated a uniform and validated standard operating procedure (SOP) to laboratories and surface-water monitoring programs that will ensure that data collected will be unbiased and environmentally relevant.
Description:
Through a Regional Applied Research Effort grant to the United States Geological Survey, Region 9 collaborated with ORD on this project to develop a standard operating procedure for collection of water and sediment samples for pyrethroid analysis.
