This book deals with the sources, distribution, analytical methods, and monitoring of Polycyclic aromatic hydrocarbons (PAH) in the occupational environment. It is hoped that this book will make a contribution to understanding the formation and determination of PAH in work atmosphere and that it will make a particular contribution to occupational health projects. Much of the information given in this book has been generating in studies carried out in cooperation with the Norwegian aluminium industry.

This book provides an overview on the molecular mode of action of carcinogenic polycyclic aromatic hydrocarbons (PAHs). PAHs are by-products arising from incomplete combustion of organic matter that are frequently released into our environment, and thus are ubiquitously detectable. Many PAHs are strong carcinogens in rodent bioassays and have been linked to increased incidences of various types of cancer in humans. The present book covers all aspects of PAH-induced carcinogenesis; it is a collection of articles written by some of the most recognizable PAH researchers, reviewing the present knowledge in this field. The topics include: exposure to and biomonitoring of PAHs in the human population; metabolic activation of PAHs; genotoxicity and repair of PAH-induced DNA damage; and factors modulating individual susceptibility to the deleterious effects of PAHs.

The effects of man-made substances (xenobiotics) on the natural environment are described in this volume. It explains why these effects need to be understood, monitored and curtailed, especially in developing countries.
Aquatic and Surface Photochemistry provides a broad overview of current research in the emerging field of environmental aquatic and surface photochemistry. Selected reviews and current research articles are blended to provide an in-depth treatment of various aspects of this research area. The first part of the text deals with photochemistry in the environment, covering recent research on the following topics: aquatic photochemistry of organic pollutants and agrochemicals, photochemical cycling of carbon and transition metals (especially iron), photochemical formation of reactive oxygen species in natural waters, photoreaction in cloud and rain droplets, and photoreactions on environmental surfaces (soil, ash, metal, oxide). The second part provides discussions and data on both heterogeneous photocatalytic and homogeneous processes, with topics ranging from applications to mechanistic studies. These chapters illustrate the wide diversity of pollutant classes that are degradable by photochemical techniques and the effects of various reaction conditions on the rates and efficiency of the techniques. Current kinetic studies are presented, which provide new information about the role of adsorption and the nature of the reactive oxidizing species that mediate these photoremediation processes.This book will interest civil, chemical, and environmental engineers, as well as chemists, soil scientists, geochemists, and atmospheric chemists.
Hydrocarbons and their derivatives (oxygenated and chlorinated, in particular), both natural and xenobiotic, represent a very large class of compounds whose conversions and degradation by microorganisms cover an extremely rich field, whose concepts are detailed in this book. The fascinating evolution of these concepts over the last twenty years has revealed the extent of the processes implemented in the environment and has multiplied their industrial applications. The resulting achievements and the current developments are described in this book.The English edition of this reference manual is an entirely revised and updated version of the French edition. It is intended for professionals, microbiologists and chemists, as well as scientists, engineers, teachers and post-doctoral researchers, who are interested by the conversions of hydrocarbons and by microbial ecology.The French edition of this book was awarded a special mention for engineering education text book by the Roberval Prize committee in 2007.
