Available in PDF, EPUB and Kindle. Book excerpt: One of the most significant factors controlling bed-sediment capacity for collecting and concentrating trace metals is grain size--as grain size decreases, metal levels increase. As a result, bed sediments can display marked chemical heterogeneity, even over relatively short distances. Consequently, the interpretation of water-quality trends through space or time based upon bed sediment-trace metal analysis requires consideration of the grain size effect. Commonly, the grain size effect is minimized by either mathematical normalization of bulk chemical data based upon an independent grain size analysis, or physical separation of a size range or fraction followed by a chemical analysis of the separated material. Normalization procedures are useful for clarifying trends but often produce over- or underestimates of metal concentrations. On the other hand, physical separation followed by chemical analysis clarifies trends and produces accurate measurements of metal levels. Based on a detailed grain size and chemical analysis of 17 samples from a wide variety of aquatic settings, and from consideration of factors such as mineralogy, ease of handling, likelihood of contamination, and cost, the most appropriate size separation for reconnaissance surveys or monitoring studies is

Download or read book A Primer on Sediment Trace Element Chemistry written by Arthur J. Horowitz and published by CRC Press. This book was released on 1991-04-23 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a basic introduction to sediment-heavy metal interactions and how sediment chemical data can be used to address environmental questions and issues. It is designed to promote self-teaching and is written so that students and professionals with a minimum of formal training in the environmental sciences can understand it. The book addresses all of the major physical and chemical factors that control sediment-trace element chemistry, as well as sampling and sampling design, data manipulation, and data interpretation. Following in the steps of the successful first edition, which was used as a text for a three day short course for U.S. Geological Survey professionals interested in sediment trace chemistry and its application to water quality issues, A Primer on Sediment-Trace Element Chemistry, 2nd Edition is ideal for academics, geochemists, chemists, hydrologists, environmental lawyers, and water quality professionals needing a comprehensive introduction to this field.

Download or read book Manual of Physico Chemical Analysis of Aquatic Sediments written by Alena Mudroch and published by Routledge. This book was released on 2017-10-05 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because water is one of the most important life-supporting media on the planet, the quality of aquatic ecosystems is of great interest to the entire world population. One of the factors that greatly affects water quality is the condition of the underlying sediment layer. The Manual of Physico-Chemical Analysis of Aquatic Sediments addresses the best methods for quantitative determination of chemical forms of different elements and compounds, bioassessment techniques, and determination of physical properties of sediments. Essential information for surveying, research, and monitoring of sediment contamination is covered. This manual will aid sediment biologists, geochemists, limnologists, regulatory program managers, environmental chemists and toxicologists and environmental consultants in preparing plans for proper remedial action.
