The emphasis is on studies that investigated pesticides in bed sediment or aquatic biota in rivers and streams in the United States. The publications reviewed are summarized in Tables and located at the end of the book respectively according to three main categories national and multistate monitoring studies state and local monitoring studies and process and matrix distribution studies. Within each of Tables and individual studies are listed by publication date and then alphabetically. Review papers Table laboratory studies and selected papers on pesticides in lakes or in foreign countries are cited in the text as needed but they are not included in Tables and . National and multistate monitoring studies Table are occurrence surveys for one or more classes of pesticides at several or many sites in multiple states. Table includes published national and multistate studies of United States estuaries as well as rivers. That is because these studies individually contribute a lot to our understanding of the national distribution of pesticide contaminants in sediment and aquatic biota. Results from some national programs were reported in a series of publications either sequential reports that each present 1-4 years of national data such as reports from the Fish and Wildlife Service s FWS National Contaminant Biomonitoring Program NCBP or regional reports that divided the national data set geographically such as reports from the National Oceanic and Atmospheric Administration s NOAA National Benthic Surveillance Project . For programs with multiple publications Table contains a data summary for each individual report published and these report summaries are grouped by program. Under each program title individual publications are ordered .
