These Proceedings contain both oral and poster contributions to the First International Conference "Field Screening Europe - Strategies and Techniques for On-Site Investigation and Monitoring of Contaminated Soil, Water and Air", held in Karlsruhe on September 29 - October 1, 1997. Environmental monitoring and the assessment of chemical contamination are becoming more and more important. The integrated study of environmental contamination in the field is a rather recent approach. "field screening" comprises field analytical tools, (quick) methods and strategies for on-site or in-situ environmental analysis and assessment of contamination. Field screening includes field analytical methods such as mobile laboratories, portable analyses, detectors, sensors, or noninvasive techniques, and also reconnaissance strategies and problems of measurement in heterogeneous media using, among others, new geotechnical and geophysical instruments.

This work talks about Field screening.

Dieses Buch ist Teil unserer neuen Datenbank Anorganik Online. Das Trennen eines Gemisches in seine einzelnen Komponenten ist eines der grundlegendsten Verfahrender Analytischen und Technischen Chemie. Dieses klassische Lehrbuch der Analytischen Chemie bietet eine zugleich umfassende und doch systematische Gliederung aller bekannten Trennverfahren. Durch seine ausführliche Behandlung der Grundprinzipien der Separationsmöglichkeiten erfasst es nicht nur das derzeit Bekannte, sondern stellt zugleich eine Fundgrube für Verfahren dar, die noch einer Weiterentwicklung harren. Das Lehrbuch ist klar strukturiert und enthält interessante Beispiele, weiterführende Literatur und ein ausführliches Register. Ein unverzichtbares Buch für fortgeschrittene Studenten der Naturwissenschaften (Chemie, Biochemie, Lebensmittelchemie, Pharmazie, Klinische Chemie, Umweltwissenschaften) und Technik (Chemische Verfahrenstechnik, Chemisch-physikalische Meßtechnik & Biotechnologie), sowie Lehrende dieser Disziplinen.

"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.

Die 10. Auflage dieses etablierten Standardwerks für Wasserfachleute bietet dem Leser einen breiten Überblick zu chemischen, hydrogeologischen und (mikro-)biologischen Themen rund um das Wasser. Außerdem enthalten sind aktuelle Informationen zu modernen chemischen und biologischen Verfahren der Wasseranalytik, praktische Aspekte der Aufbereitung, Desinfektion und Verwendung von Wasser sowie zur Abwasserreinigung und zum Schutz von Gewässern.

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.

The separation of a mixture into its individual components is one of the most fundamental procedures in analytical and industrial chemistry. This classic book in analytical chemistry provides a comprehensive yet systematic outline of all known separation methods. Through its detailed treatment of the basic principles of separation possibilities, it not only covers what is currently known, but also represents a treasure trove of methods that are still awaiting further development. It is clearly structured and contains interesting examples, further reading and a detailed index. An indispensable book for advanced students of natural sciences (chemistry, biochemistry, food chemistry, pharmacy, clinical chemistry, environmental sciences) and technology (chemical engineering, chemical-physical measurement & biotechnology), as well as teachers of these disciplines.

These Proceedings contain both oral and poster contributions to the first interna­ tional conference" Field Screening Europe - Strategies and Techniques for On-Site Investigation and Monitoring of Contaminated Soil, Water and Air", held in Karls­ ruhe September 29 - October 1, 1997. Environmental monitoring and the assessment of chemical contaminations are be­ coming more and more important. The integrated study of environmental con­ tamination in the field is a rather recent approach. "Field screening" indicates such field analytical tools, (quick) methods and strategies for on-site or in-situ environmental analysis and assessment of contamination. The classical strategy for investigating contaminants consists of the following steps: site studies, sampling, sample transport to the laboratory, sample preparation, and analysis. This strategy is rather expensive and time consuming. Some investiga­ tions, including sample preparation, may last several days. In many cases, the results must be available immediately and are of importance for further decisions. Field screening is an alternative or complement to this strategy that attempts to be cheaper and faster and may achieve the same quality of results. The most important argument for field analytical methods is that the superior accuracy and high costs of laboratory methods are disproportional to the possibility of arti­ facts from sampling and errors originating from spatial variations of contaminants.

As an integrated study of environmental contamination, "field screening" has become a more and more important part of environmental monitoring and the assessment of chemical contaminations. Recent developments are presented in these proceedings.Audience: Environmental engineers, geo-scientists, chemists, biologists, soil scientists, hydrologists and geophysicists.
