The thermal instability of PVC poses problems in melt recycling processes but its widespead use in high volume production demands that practical solutions must be found. Among the topics receiving detailed attention are stabilizers, compatibilisers, contaminants, UV stability, mixed plastics wastes, and blending technologies.

Mercury pollution and contamination are widespread, well documented, and continue to pose a public health concern in both developed and developing countries. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly to include the fields of biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists begun to establish a holistic approach to studying mercury pollution that integrates chemistry, biology, and human health sciences. "Mercury in the Environment" follows the process of mercury cycling through the atmosphere, through terrestrial and aquatic food webs, and through human populations to develop a comprehensive perspective on this important environmental problem. This timely reference also provides recommendations on mercury remediation, risk communication, education, and monitoring.

Every day, large quantities of volatile organic compounds (VOCs) are emitted into the atmosphere from both anthropogenic and natural sources. The formation of gaseous and particulate secondary products caused by oxidation of VOCs is one of the largest unknowns in the quantitative prediction of the earth’s climate on a regional and global scale, and on the understanding of local air quality. To be able to model and control their impact, it is essential to understand the sources of VOCs, their distribution in the atmosphere and the chemical transformations which remove these compounds from the atmosphere. In recent years techniques for the analysis of organic compounds in the atmosphere have been developed to increase the spectrum of detectable compounds and their detection limits. New methods have been introduced to increase the time resolution of those measurements and to resolve more complex mixtures of organic compounds. Volatile Organic Compounds in the Atmosphere describes the current state of knowledge of the chemistry of VOCs as well as the methods and techniques to analyse gaseous and particulate organic compounds in the atmosphere. The aim is to provide an authoritative review to address the needs of both graduate students and active researchers in the field of atmospheric chemistry research.

Air pollution affects populations throughout the world, having a significant impact on public health. An important source of these pollutants is the motor vehicle. In our attempt to address some of the issues within the field in this volume, it is clear that there is sufficient material to fill many volumes. In this context, we decided to address a number of issues which have either been neglected or which pose important critical questions. We begin with the role of the nose of modulating or initiating responses to air pollutants, move through the epidemiological and experimental evidence that cardiac function is disturbed by pollution, and then address the question of point sources as opposed to area sources when trying to apportion exposure sources with respect to specific health effects. New work on the structure of particles and their toxicology then leads to a chapter addressing how best we might determine particle toxicity in the future. This is of particular relevance at present in view of the increasing concerns regarding manufactured nanomaterials. The volume concludes with a new approach to an assessment of the health impacts of air pollution — an area where pohcy developers keenly feel the need, when determining how best to address air pollution control. We hope that you will find some of these areas useful.

Written for researchers and practitioners in environmental pollution, management and ecology, this interdisciplinary account explores the ecological issues associated with industrial pollution to provide a complete picture of this important environmental problem from cause to effect to solution. Bringing together diverse viewpoints from academia and environmental agencies and regulators, the contributors cover such topics as biological resources of mining areas, biomonitoring of freshwater and marine ecosystems and risk assessment of contaminated land in order to explore important questions such as: What are the effects of pollutants on functional ecology and ecosystems? Do current monitoring techniques accurately signal the extent of industrial pollution? Does existing policy provide a coherent and practicable approach? Case studies from throughout the world illustrate major themes and provide valuable insights into the positive and negative effects of industrial pollution, the provision of appropriate monitoring schemes and the design of remediation and restoration strategies.

The quantity and quality of waste generated and discharged into natural water bodies is a topic of serious concern. Consequently, there is a need for different strategies to address wastewater treatment and subsequent reuse, especially in arid and semi-arid areas where water shortages are the rule. Biological treatment processes constitute crucial tools in the biodegradation of organic matter, transformation of toxic compounds into harmless products, and nutrient removal in wastewater microbiology.
