ABSTRACT
Assessment of freshwater sediments can determine whether chemical concentrations are sufficient to cause adverse effects on aquatic organisms or organisms higher in the food chain, including humans. This book presents methods for assessing sediments and includes an integration of physical, chemical, and biological information. It examines the elements of quality assurance and control programs, considerations for the conduct of field surveys, screening-level analyses, chemical analyses, toxicity tests for assessing biological impacts, assessments of benthic invertebrate community structure, surveys of fish tumors and abnormalities, and data presentation and interpretation techniques.
