Book Description
Today more than 5 million chemicals are known and roughly 100,000 of them are frequently used, with both numbers rising. Many of these chemicals are ultimately released into the environment and may cause adverse effects to ecosystems and human health. Effect-directed analysis (EDA) is a promising tool for identifying predominant toxicants in complex, mostly environmental mixtures combining effect testing, fractionation and chemical analysis. In the present book leading experts in the field provide an overview of relevant approaches and tools used in EDA. This includes diagnostic biological tools, separation techniques and advanced analytical and computer tools for toxicant identification and structure elucidation. Examples of the successful application of EDA are discussed such as the identification of mutagens in airborne particles and sediments, of endocrine disruptors in aquatic ecosystems and of major toxicants in pulp and paper mill effluents. This book is a valuable, comprehensive and interdisciplinary source of information for environmental scientists and environmental agencies dealing with the analysis, monitoring and assessment of environmental contamination.

Book Description
Numerous compounds are continuously released into the environment in large quantities e.g. solvents, dyes and varnishes, herbicides, insecticides, as well as many biologically active compounds such as hormones and antibiotics. They are suspicious as the cause of adverse effects to biota, including mutagenicity, carcinogenicity, and endocrine disruption. To ensure this problem to be minimized in the future, hazard chemicals need to be identified in the environment. A simple analytical screening, of e.g. water bodies, is insufficient to detect harmful compounds. To facilitate the assignment of adverse effects of complex environmental mixtures, the combination of chemical fractionation, specific biological endpoint detection and chemical identification combined with qualitative structure-activity relationships (QSAR) should be applied known as Effect-directed analysis (EDA). However, toxicant identification in isolated fractions is still one of the biggest challenges in EDA, since these fractions often remain complex even after extensive HPLC-based fractionation. Therefore, preparative capillary gas chromatography (pcGC) - a method that holds promise to overcome this problem - is presented here. The resolving power of capillary gas chromatography compared to LC suggests to include this technique into effect-directed fractionation procedures. Moreover, toxicity confirmation using computer tools based on substructure identification and structure generation combined with QSAR models is used in this study to establish reliable cause-effect relationships.

Book Description
Over the last 15 years, the focus of chemical pollution has shifted from conventional pollutants to so-called “emerging” or “new” unregulated contaminants. These include pharmaceuticals and personal care products, hormones, UV filters, perfluorinated compounds, poylybrominated flame retardants (BFRs), pesticides, plasticizers, artificial sweeteners, illicit drugs, and endocrine disruptor compounds (EDCs). Despite the increasing number of published studies covering emerging contaminants, we know almost nothing about the effects of their transformation products and/or metabolites. This two-volume set provides a unique collection of research on transformation products, their occurrence, fate and risks in the environment. It contains 32 chapters, organised into 7 parts, each with a distinct focus: • General Considerations • Transformation Processes and Treatment Strategies • Analytical Strategies • Occurrence, Fate and Effects in the Environment • Global Speciality and Environmental Status • Risk Assessment, Management and Regulatory Framework • Outlook Transformation Products of Emerging Contaminants in the Environment is a valuable resource for researchers and industry professionals in environmental chemistry, analytical chemistry, ecotoxicology, environmental sciences, and hydrology, as well as environmental consultants and regulatory bodies.

Book Description
This book provides a unique source of reference on the chemical analysis of potentially contaminated land. It assists in specifying appropriate analyses, relevant strategies for carrying out analyses, and methods of interpreting results within the new risk-based legislative framework for contaminated land. It addresses all aspects of the analysis, from delivery of the samples to the laboratory to the presentation of the results to the clients. Emphasis is placed on concentrated, tabular data, wherever possible. Problems of analysis are highlighted and solutions are proposed. Asbestos is covered in detail in the chapter on inorganic parameters, and a chapter is included on the new techniques of ecotoxicity measurement. Directed equally at the analytical chemist and the environmental scientist or engineer responsible for commissioning analyses of potentially contaminated soil or water samples, the book is written in a way that will prove helpful to both new and experienced practitioners. As such, it is one of the first volumes to bridge the gap between the customer and the supplier.

Book Description
A major issue that has remained prevalent in today’s modern world has been the presence of chemicals within water sources that the public uses for drinking. The associated health risks that accompany these contaminants are unknown but have sparked serious concern and emotive arguments among the global community. Empirical research is a necessity to further understand these contaminants and the effects they have on the environment. Effects of Emerging Chemical Contaminants on Water Resources and Environmental Health is a pivotal reference source that provides vital research on current issues regarding the occurrence, toxicology, and abatement of emerging contaminants in water sources. While highlighting topics such as remediation techniques, pollution minimization, and technological developments, this publication explores sample preparation and detection of these chemical contaminants as well as policy and legislative issues related to public health. This book is ideally designed for environmental engineers, biologists, health scientists, researchers, students, and professors seeking further research on the latest developments in the detection of water contaminants.
