This book was released on 2021-09-07 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of these updated global guidelines is to offer health-based air quality guideline levels, expressed as long-term or short-term concentrations for six key air pollutants: PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. In addition, the guidelines provide interim targets to guide reduction efforts of these pollutants, as well as good practice statements for the management of certain types of PM (i.e., black carbon/elemental carbon, ultrafine particles, particles originating from sand and duststorms). These guidelines are not legally binding standards; however, they provide WHO Member States with an evidence-informed tool, which they can use to inform legislation and policy. Ultimately, the goal of these guidelines is to help reduce levels of air pollutants in order to decrease the enormous health burden resulting from the exposure to air pollution worldwide.

Download or read book Variability in the Fraction of Ambient Fine Particulate Matter in Indoor Air and Implications for Air Pollution Epidemiology written by Natasha Hodas and published by . This book was released on 2014 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure to ambient fine particulate matter (PM2.5) is associated with multiple negative health outcomes. Studies investigating these associations commonly use PM2.5 concentrations measured at outdoor, central-site monitors to estimate exposure. Because people spend the majority of time indoors, however, the variable efficiency with which ambient PM2.5 penetrates and persists indoors is a source of error in epidemiologic analyses. This error generally results in an underestimation of health effects, hampering the detection of associations between ambient PM2.5 exposures and the risk of health outcomes. To reduce this error, practical methods to model indoor concentrations of ambient PM2.5 are needed. This dissertation contributes to exposure science by advancing existing models of residential exposure to ambient PM2.5 and by improving the robustness and accessibility of these tools. First, drivers of variability in the fraction of ambient PM2.5 found indoors (F) are identified and the potential for this variability to explain observed heterogeneity in PM-mediated health-effect estimates is explored. Next, a physically-based mass-balance model and modeling tools that account for variability in human activity patterns (e.g. time spent in various indoor and outdoor environments) are used to compute ambient PM2.5 exposures that account for the modification of PM2.5 with outdoor-to-indoor transport in order to explore whether the use of these refined exposure surrogates reduces error and bias in epidemiologic analyses. Subsequently, this outdoor-to-indoor transport model is evaluated and refined using measured indoor and outdoor PM2.5 concentrations and air exchange rates, providing a practical and robust tool for reducing exposure misclassification in epidemiologic studies. Finally, the volatility basis set is used for the first time to study shifts in the gas-particle partitioning of ambient organics with transport indoors. This dissertation provides guidance regarding measurements and data most critically needed to facilitate the prediction of refined exposure surrogates in large epidemiological studies and, thus, informs the design of future sampling campaigns and epidemiologic studies. It enables a better accounting of ambient particle penetration into and persistence in the indoor environment and constitutes an important advancement in the efforts to reduce exposure error in epidemiologic studies and to elucidate relationships between PM2.5 exposure and adverse health outcomes.

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.
Download or read book Climate Change the Indoor Environment and Health written by Institute of Medicine and published by National Academies Press. This book was released on 2011-10-01 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indoor environment affects occupants' health and comfort. Poor environmental conditions and indoor contaminants are estimated to cost the U.S. economy tens of billions of dollars a year in exacerbation of illnesses like asthma, allergic symptoms, and subsequent lost productivity. Climate change has the potential to affect the indoor environment because conditions inside buildings are influenced by conditions outside them. Climate Change, the Indoor Environment, and Health addresses the impacts that climate change may have on the indoor environment and the resulting health effects. It finds that steps taken to mitigate climate change may cause or exacerbate harmful indoor environmental conditions. The book discusses the role the Environmental Protection Agency (EPA) should take in informing the public, health professionals, and those in the building industry about potential risks and what can be done to address them. The study also recommends that building codes account for climate change projections; that federal agencies join to develop or refine protocols and testing standards for evaluating emissions from materials, furnishings, and appliances used in buildings; and that building weatherization efforts include consideration of health effects. Climate Change, the Indoor Environment, and Health is written primarily for the EPA and other federal agencies, organizations, and researchers with interests in public health; the environment; building design, construction, and operation; and climate issues.

This book was released on 2024-02-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Schools, workplaces, businesses, and even homes are places where someone could be subjected to particulate matter (PM) ? a mixture of solid particles and liquid droplets found in the air. PM is a ubiquitous pollutant comprising a complex and ever-changing combination of chemicals, dust, and biologic materials such as allergens. Of special concern is fine particulate matter (PM2.5), PM with a diameter of 2.5 microns ( Health Risks of Indoor Exposure to Fine Particulate Matter and Practical Mitigation Solutions explores the state-of the-science on the health risks of exposure to fine particulate matter indoors along with engineering solutions and interventions to reduce risks of exposure to it, including practical mitigation strategies. This report offers recommendations to reduce population exposure to PM2.5, to reduce health impacts on susceptible populations including the elderly, young children, and those with pre-existing conditions, and to address important knowledge gaps.

This book was released on 2016-09-26 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) defines PM as a mixture of extremely small particles and liquid droplets comprising a number of components, including "acids (such as nitrates and sulfates), organic chemicals, metals, soil or dust particles, and allergens (such as fragments of pollen and mold spores)". The health effects of outdoor exposure to particulate matter (PM) are the subject of both research attention and regulatory action. Although much less studied to date, indoor exposure to PM is gaining attention as a potential source of adverse health effects. Indoor PM can originate from outdoor particles and also from various indoor sources, including heating, cooking, and smoking. Levels of indoor PM have the potential to exceed outdoor PM levels. Understanding the major features and subtleties of indoor exposures to particles of outdoor origin can improve our understanding of the exposureâ€"response relationship on which ambient air pollutant standards are based. The EPA's Indoor Environments Division commissioned the National Academies of Sciences, Engineering, and Medicine to hold a workshop examining the issue of indoor exposure to PM more comprehensively and considering both the health risks and possible intervention strategies. Participants discussed the ailments that are most affected by particulate matter and the attributes of the exposures that are of greatest concern, exposure modifiers, vulnerable populations, exposure assessment, risk management, and gaps in the science. This report summarizes the presentations and discussions from the workshop.

This book was released on 2012-10-28 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the use of personal products to our consumption of food, water, and air, people are exposed to a wide array of agents each day-many with the potential to affect health. Exposure Science in the 21st Century: A Vision and A Strategy investigates the contact of humans or other organisms with those agents (that is, chemical, physical, and biologic stressors) and their fate in living systems. The concept of exposure science has been instrumental in helping us understand how stressors affect human and ecosystem health, and in efforts to prevent or reduce contact with harmful stressors. In this way exposure science has played an integral role in many areas of environmental health, and can help meet growing needs in environmental regulation, urban and ecosystem planning, and disaster management. Exposure Science in the 21st Century: A Vision and A Strategy explains that there are increasing demands for exposure science information, for example to meet needs for data on the thousands of chemicals introduced into the market each year, and to better understand the health effects of prolonged low-level exposure to stressors. Recent advances in tools and technologies-including sensor systems, analytic methods, molecular technologies, computational tools, and bioinformatics-have provided the potential for more accurate and comprehensive exposure science data than ever before. This report also provides a roadmap to take advantage of the technologic innovations and strategic collaborations to move exposure science into the future.

Download or read book Indoor Exposure to Fine Particulate Matter and Practical Mitigation Approaches written by National Academy of Engineering and published by . This book was released on 2022-10-26 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overwhelming evidence exists that exposure to outdoor fine particulate matter (PM2.5) is associated with a range of short-term and chronic health impacts, including asthma exacerbation, acute and chronic bronchitis, heart attacks, increased susceptibility to respiratory infections, and premature death, with the burden of these health effects falling more heavily on underserved and marginalized communities. Although less studied to date, indoor exposure to PM2.5 is also gaining attention as a potential source of adverse health effects, particularly given that Americans spend 90 percent of their lives indoors and indoor PM2.5 levels can exceed outdoor levels. To better understand the sources of indoor PM2.5, the possible health effects of exposure to indoor PM2.5, and engineering approaches and interventions to reduce those exposure risks, the National Academies of Sciences, Engineering, and Medicine convened a virtual workshop, Indoor Exposure to Fine Particulate Matter and Practical Mitigation Approaches, on April 14, 21, and 28, 2021. The workshop focused on exposures that occur in residential and school buildings and on existing and practical mitigation technologies and approaches. This publication summarizes the presentation and discussion of the workshop.
