E-raamat: Contaminated Sediments in Freshwater Systems [Taylor & Francis e-raamat]

Spellman helps environmental engineers, scientists, managers, and students to understand contaminated sediments in freshwater systems better. He describes scientifically sound methods for assessing sediment quality to determine whether chemical or biological concentrations in the sediments are sufficient to cause adverse effects on either aquatic organisms or organisms higher in the food chain, including humans. In sections on sediment fundamentals, sediment damage, and sediment sampling, he considers such topics as surface water sediments, the transport of sediment by water, physical sediment damage, chemically contaminated sediments, and collecting porewater. He presents an extended case study of Gold King Mine Spill in 2015. Annotation ©2017 Ringgold, Inc., Portland, OR (protoview.com)

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.
