Monitoring Of Fine Particulate Matter Pm2 5 In The Comox Valley Regional District Bc

Particulate matter (PM)-dust, dirt, smoke, soot, and liquid droplets-comes from a variety of sources and is a mixture of many pollutants made up of several different chemical species. Recent evidence about health effects and the fundamental physical and chemical differences between fine and coarse PM prompted the EPA to set new standards. Monitoring to determine whether an area has met these standards requires a comprehensive approach that combines analytical techniques to assess mass and chemical composition with an integrated network of ambient and source PM monitors.

Exposure to noise at home, at work, while traveling, and during leisure activities is a fact of life for all Americans. At times noise can be loud enough to damage hearing, and at lower levels it can disrupt normal living, affect sleep patterns, affect our ability to concentrate at work, interfere with outdoor recreational activities, and, in some cases, interfere with communications and even cause accidents. Clearly, exposure to excessive noise can affect our quality of life. As the population of the United States and, indeed, the world increases and developing countries become more industrialized, problems of noise are likely to become more pervasive and lower the quality of life for everyone. Efforts to manage noise exposures, to design quieter buildings, products, equipment, and transportation vehicles, and to provide a regulatory environment that facilitates adequate, cost-effective, sustainable noise controls require our immediate attention. Technology for a Quieter America looks at the most commonly identified sources of noise, how they are characterized, and efforts that have been made to reduce noise emissions and experiences. The book also reviews the standards and regulations that govern noise levels and the federal, state, and local agencies that regulate noise for the benefit, safety, and wellness of society at large. In addition, it presents the cost-benefit trade-offs between efforts to mitigate noise and the improvements they achieve, information sources available to the public on the dimensions of noise problems and their mitigation, and the need to educate professionals who can deal with these issues. Noise emissions are an issue in industry, in communities, in buildings, and during leisure activities. As such, Technology for a Quieter America will appeal to a wide range of stakeholders: the engineering community; the public; government at the federal, state, and local levels; private industry; labor unions; and nonprofit organizations. Implementation of the recommendations in Technology for a Quieter America will result in reduction of the noise levels to which Americans are exposed and will improve the ability of American industry to compete in world markets paying increasing attention to the noise emissions of products.

The concept of carbonaceous aerosol has only recently emerged from atmospheric pollution studies; even standard nomenclature and terminology are still unsettled. This monograph is the first to offer comprehensive coverage of the nature and atmospheric role of carbonaceous aerosol particles. Atmospheric chemists, physicists, meteorologists, and modellers will find this a thought-inspiring and sometimes provocative overview of all global phenomena affected by or related to carbonaceous aerosol.

Exposure to ambient air pollutants, both indoors and outdoors has been associated with the exacerbation and also in the etiology of diverse human diseases. This book offers an overview of our current understanding of air pollution health risks and how this knowledge is being used in the regulatory, therapeutic intervention measures to protect the public health and reduce the disease burden caused by acute and long-term exposure to air pollutants. Air Pollution and Health Effects provides readers with a comprehensive understanding of air pollution health risks, morbidity and the global disease burden, whilst also delivering critical review on state of the art research so as to gain a fundamental understanding of the biological mechanisms involved in the etiology of air pollution-induced diseases. Chapters range from pregnancy outcomes and pre-term birth, carcinogens in the ambient aerosol and the health consequences of indoor biomass burning. Special emphasis is placed on regional and local air pollution and its impact on global health along with suitable preventive and interventional measures. With contributions from international experts in the field this volume is a valuable guide for researchers and clinicians in toxicology, medicine and public health as well as industry and government regulatory scientists involved in health protection.
