The analysis of soils and sediments for pollutants is increasingly required in today's industrial world. It is therefore important that extraction procedures used for environmental risk assessment studies, production of certified reference materials and applications of extraction schemes are standardised throughout the scientific community. This book deals specifically with operationally-defined extraction methods for the determination of "fractions" of elements in soil and sediment matrices. Bringing together the work of a number of different international laboratories, the book describes single and sequential extraction procedures. It then goes on to present a summary of the latest research on extraction/leaching tests for the determination of trace organic compounds in wastes, followed by an outline of an international network which aims to standardise extraction and leaching methodologies for their applications to various environmental matrices. Methodologies for Soil and Sediment Fractionation Studies will be welcomed by researchers and analysts in academia, industry and government institutions worldwide.
