Measurement Of Airborne Pollutants

Measurement of Airborne Pollutants stresses the importance of developing air pollution measurements that is central to progress in the formulation of environmental policy, efficient regulation of emissions, and satisfactory control of processes which emit pollutants into the atmosphere. This book is divided into two parts. Part 1 deals with the operational evaluations of emerging techniques for ambient measurements of airborne particles and for low levels of nitrogen dioxide. The calibration techniques for automatic analyses or for gas cylinders obtained from commercial suppliers and fundamental issues in the measurement of acid deposition are also deliberated. The assessment of air pollution sources that includes analyzing dioxins and furans at sub-nanogram levels and particle or dust source assessments through dust deposit and particle flux gauges are described in Part 2. This publication is valuable to environmental scientists and researchers concerned with air pollution measurements.

Sampling and Analysis of Airborne Pollutants is a compilation of recent work addressing air pollution and the measurement of airborne compounds conducted by leading environmental scientists. Themes ranging from electro-optical remote sensing to new directions in sampling techniques are represented, and topics covered include innovative sampling methods, visibility research in national parks, analysis of carbonyl compounds, artifacts in aerosol sampling, methods of volatile organic compound (VOC) sampling and analysis, data interpretation of ambient VOC data, and interpretation of data from environmental tobacco smoke. Sampling and Analysis of Airborne Pollutants presents topical reference material that will be valuable to air pollution scientists, statisticians in air pollution, consultants, and analytical chemists.

Most people in the United States spend far more time indoors than outdoors. Yet, many air pollution regulations and risk assessments focus on outdoor air. These often overlook contact with harmful contaminants that may be at their most dangerous concentrations indoors. A new book from the National Research Council explores the need for strategies to address indoor and outdoor exposures and examines the methods and tools available for finding out where and when significant exposures occur. The volume includes: A conceptual framework and common terminology that investigators from different disciplines can use to make more accurate assessments of human exposure to airborne contaminants. An update of important developments in assessing exposure to airborne contaminants: ambient air sampling and physical chemical measurements, biological markers, questionnaires, time-activity diaries, and modeling. A series of examples of how exposure assessments have been applied-properly and improperly-to public health issues and how the committee's suggested framework can be brought into practice. This volume will provide important insights to improve risk assessment, risk management, pollution control, and regulatory programs.

This book presents a wealth of new information that enables environmental scientists and authorities to design methods for measuring and modelling emission rates related to specific pollution sources, and thus to generate improved emission inventories and reduction strategies. The text shows how to carry out experiments to verify emission data, including tunnel and open motorway studies, comprehensive city experiments and tracer experiments.

This established textbook offers a one-stop, comprehensive coverage of air pollution, all in an easy-reading and accessible style. The fourth edition, broadly updated and developed throughout, includes a brand-new chapter providing a broader overview to the topic for general reading, and presents fresh materials on air pollution modelling, mitigation and control, tailored to the needs of both amateur and specialist users. Retaining a quantitative perspective, the covered topics include: gaseous and particulate air pollutants, measurement techniques, meteorology and modelling, area sources, mobile sources, indoor air, effects on plants, materials, humans and animals, impact on climate change and ozone profiles and air quality legislations. This edition also includes a final chapter covering a suite of sampling and laboratory practical experiments that can be used for either classroom teachings, or as part of research projects. As with previous editions, the book is aimed to serve as a useful reading resource for upper-level undergraduate and postgraduate courses specialising in air pollution, with dedicated case studies at the end of each chapter, as well as a list of revision questions provided at the end as a complementary section.

Addressing the matter of air quality in a collection of focused scientific topic chapters is timely as a contribution to the international discussion and challenges of global warming and climate change. This book engages with the debate by considering some of the social, public health, economic and scientific issues that relate to the contribution made by airborne pollutants to the observable trending variances in weather, climate and atmospheric conditions. From a wide range of submissions for inclusion in the book, there are seven carefully selected chapters that individually relate to air sampling and analysis: the monitoring, measurement and modelling of air quality. The authors come from a range of academic and scientific disciplines, and each is internationally credited in his/her field. This book will appeal to scholars, to students and generally to those interested in the following contemporary thought in the matter of environment pollution, air quality and the issues of climate and atmosphere the world is facing today.
