While natural sources contribute substantially to local air pollution in arid regions more prone to forest fires and dust storms, the contribution from human activities far exceeds natural sources. Found insideThis edition explores the processes and equipment that produce less pollution in the atmosphere. This book is comprised of six parts encompassing 28 chapters. Indoor air pollution, caused by carpets, household chemicals or even furniture or building materials, may have detrimental health effects, especially for those with health risks like asthma or even allergies. Therefore, ambient concentration data—while useful for characterizing outdoor air quality—ultimately do not fully represent human exposures, because ambient air monitoring equipment measures air quality at fixed outdoor locations, while people breathe air in several indoor and outdoor environs throughout a typical day. Outdoor air pollution contains numerous substances of both natural (e.g., pollen, mold spores, dust) and anthropogenic (human-caused) origin. Welfare costs associated with these deadly consequences are projected to rise to as much as $25 trillion over the same period. The major sources of air pollution are transportation engines, power and heat generation, industrial processes, and the burning of solid waste solid waste, discarded materials other than fluids. This volume of the Encyclopedia of Sustainability Science and Technology, Second Edition, provides a broad and comprehensive view of air pollution, extending from ground-level, localized air quality and regional and global air quality and ...

The health impact from these outdoor sources includes an increased risk of stroke, heart disease, lung cancer, and chronic and acute respiratory diseases. Most air pollution, harmful gases and particles in the air, affecting national parks is created outside park boundaries. Ambient (outdoor) air pollution in both cities and rural areas was estimated to cause 4.2 million premature deaths worldwide per year in 2016; this mortality is due to exposure to fine particulate matter of 2.5 microns or less in diameter (PM2.5), which .

What has made it a global issue? The greatest sources of CO to outdoor air are cars, trucks and other vehicles or machinery that burn fossil fuels. Primary. Most sources of outdoor air pollution are well beyond the control of individuals and demand action by cities, as well as national and international policymakers in sector like transport, energy waste management, buildings and agriculture. Outdoor air pollutants are formed during natural and anthropogenic processes. Carbon monoxide (CO) is a toxic air pollutant produced largely from vehicle emissions. The research also states that the most dangerous consequences from outdoor air pollution are related to the number of premature deaths: pollution could lead to 9 million of them by 2060. Determining exposures to outdoor air pollution requires a complex assessment that factors in the amount and types of air pollution, the number of people exposed, and the exposure duration. The ozone report: Measuring progress through 2003. We primarily assume that all particles are equally toxic, but also include a sensitivity study that . industry and better municipal waste management would reduce key sources of outdoor air pollution.
