WHO Guidelines for Indoor Air Quality


Book Description

This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.

Air Distribution in Rooms


Book Description

The air distribution in occupied spaces is a major issue of public concern. It is widely recognized that the quality of air and the nature of airflow can affect the health of occupants and the energy consumed in buildings and transport vehicles. ROOMVENT is the principal international conference in the field of air distribution. It was first initiated in 1987 by SCANVAC, the Scandinavian Federation of Heating, Ventilating and Sanitary Engineering Associations in Denmark, Finland, Iceland, Norway and Sweden. The aim of the Conference is to bring together researchers from universities and research institutes, engineers from industry and government officials and policy makers, with the goal of experiencing the latest techniques for measuring and analyzing indoor air flow, the visualization of indoor air flow patterns, the evaluation of ventilation parameters and the most recent developments in computer simulation techniques of room airflow. It is hoped that the theme of ROOMVENT 2000 "Ventilation for Health and Sustainable Environment" will set the scene for room air distribution research and development for the new millennium.




Clearing the Air


Book Description

Since about 1980, asthma prevalence and asthma-related hospitalizations and deaths have increased substantially, especially among children. Of particular concern is the high mortality rate among African Americans with asthma. Recent studies have suggested that indoor exposuresâ€"to dust mites, cockroaches, mold, pet dander, tobacco smoke, and other biological and chemical pollutantsâ€"may influence the disease course of asthma. To ensure an appropriate response, public health and education officials have sought a science-based assessment of asthma and its relationship to indoor air exposures. Clearing the Air meets this need. This book examines how indoor pollutants contribute to asthmaâ€"its causation, prevalence, triggering, and severity. The committee discusses asthma among the general population and in sensitive subpopulations including children, low-income individuals, and urban residents. Based on the most current findings, the book also evaluates the scientific basis for mitigating the effects of indoor air pollutants implicated in asthma. The committee identifies priorities for public health policy, public education outreach, preventive intervention, and further research.




Indoor Air Quality


Book Description

Indoor Air Quality: Sampling Methodologies provides environmental professionals and industrial hygienists with the latest information available in "indoor air quality sampling." In most instances, there are no established government protocols. In this book, the author presents prominent contributions and discusses the practical concerns that determine which sampling approach is best for a given situation. The author defines and clarifies indoor air quality and its historic background. She presents a diagnostic approach to addressing health concerns, brief overview of air handling systems, observations to be made regarding indoor activities, information regarding air emissions from other buildings, and a discussion of individual susceptibilities to various substances. The book covers sampling strategies, sampling/analytical protocols, suggested uses for these protocols, and a means for interpreting results. A one-of-a-kind, practical guide for assessing indoor air quality, this book gives you step-by-step instructions for all sampling tasks and includes background information, occurrence and uses of contaminants, exposure and diagnostic sampling and analytical protocols, and helpful hints based on the author's observations and experience. It shows you how to develop a theory and follow it through to identification of unknown air contaminants. The book contains more than 150 charts, tables, photographs, and drawings and includes an extensive glossary and symptoms index. No other book offers you the concise, in-depth, and practical coverage you will find in Indoor Air Quality: Sampling Methodologies.
