Soils play a central role in the conversion of organic matter and element fluxes because of the large number of microorganisms present in the soil. In this book the more important processes that are driven by microbiological activity are discussed. It will be of interest to students of chemistry, biology, ecology, soil science and related areas. Researchers from these fields will profit from extended literature surveys in each chapter comprising important findings from early as well as the most recent investigations.

Based on discussions at the 2007 SETAC Europe PERAS Workshop in Coimbra, Semi-Field Methods for the Environmental Risk Assessment of Pesticides in Soil presents a timely summary of state-of-the-art higher-tier terrestrial risk assessment of plant protection products (PPPs). Influential regulators, academics, and industry scientists provide a comprehensive, science-based view to guide regulatory authorities and manufacturers in assessing the higher-tier terrestrial risks of PPPs in the environment. The book includes a clear description of how to perform a higher-tier terrestrial risk assessment and provides a single reference on the subject. It examines various types of semi-field methods for soil assessment, including the use of terrestrial model ecosystems for pesticide risk assessment. In addition, the text also explores legislative and regulatory issues and offers technical recommendations. The book provides guidance on how to assess the soil risks of pesticides in the environment and explains how to use semi-field methods to access how pesticides may lead to spatial and temporal changes in soil biological communities and the larger agricultural landscape.

"Organic Trace Analysis" presents the basics of trace analysis, from sample preparation to the measurement: Students are introduced to statistical evaluation, quality control technologies, sampling and preparation of organic traces, as well as to enrichment and separation of samples. Spectroscopic techniques as chromatography, capillary electrophoresis, mass spectrometry, and receptor-based bioanalysis are presented in detail.

Organic contaminants even in very low concentrations can have toxic and ecotoxic effects on exposed organisms. Detection and quantification of such trace amounts in diverging matrices (e.g., water, air, soil, food, tissue, organisms) is challenging and great carefulness and strategic thinking is needed to get reliable results along the way from taking samples up to the final analysis. In the 2nd edition, besides revisions of existing chapters, new analytical technologies and recent application examples are presented: non-target mass spectrometric analysis, trace analysis of per- and polyfluoroalkylated "forever chemicals", organophosphorus esters (nerve agents), and micro- and nanoplastic particles in the environment. Students will learn about peculiarities and state of the art organic trace analysis and acquire basic and advanced principles of statistical evaluation of analytical results quality control strategies and good laboratory practices sampling techniques from various matrices sample treatment, enrichment and clean-up techniques chromatographic analyses including hyphenated techniques, and spectroscopy as well mass spectrometry and bioanalytical tools. An extended chapter on selected applications will transfer the theoretical understanding into applied scientific problems. Students will profit from a comprehensive and state of the art overview of organic trace analyses and from an extensive collection of relevant literature.
