Encompassing papers presented at the 25th International Conference on Modelling, Monitoring and Management of Air Pollution, this book is the latest from a successful conference series. International academics and air pollution experts address various aspects of air pollution and provide an insight into the science and policy frameworks. The management of air pollution is one of the most challenging problems facing the international community. The need to balance concern for the environment with the demand for generating economic growth makes air pollution a particularly challenging issue, requiring global attention and cooperation. Science can help us identify the nature and scale of air pollution impacts and it has become essential in guiding government decisions regarding the most appropriate and effective regulations. This book presents advances in our knowledge of the science of air pollution. The Air Pollution series of conferences has consistently recognised that science remains the key to identifying the nature and scale of air pollution impacts and reaffirmed that science is essential in the formulation of policy relevant information for regulatory decision making. The conference series also acknowledged, at a very early stage, that science alone will not improve a polluted atmosphere. Scientific knowledge derived from well-designed studies needs to be allied with additional technical and economic studies in order to ensure cost effective and efficient mitigation. Leading research originating all over the world is included and covers the subsequent topics: Air pollution modelling; Monitoring and measuring; Air quality management; Indoor air pollution; Aerosols and particles; Industrial and travel emissions; Exposure and health effects; Economics of air pollution control; Innovative technologies; Challenges for the future; Strategic and project assessment; Green technologies and techniques; Stationary and mobile emissions; Social economic issues; Environmental impact assessment; Air pollution and climate change; Air quality forecasting.

Download Health Risks of Indoor Exposure to Particulate Matter in PDF, Epub, and Kindle

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.

Non-Exhaust Emissions: An Urban Air Quality Problem for Public Health comprehensively summarizes the most recent research in the field, also giving guidance on research gaps and future needs to evaluate the health impact and possible remediation of non-exhaust particle emissions. With contributions from some of the major experts and stakeholders in air quality, this book comprehensively defines the state-of-the-art of current knowledge, gaps and future needs for a better understanding of particulate matter (PM) emissions, from non-exhaust sources of road traffic to improve public health. PM is a heterogeneous mix of chemical elements and sources, with road traffic being the major source in large cities. A significant part of these emissions come from non-exhaust processes, such as brake, tire, road wear, and road dust resuspension. While motor exhaust emissions have been successfully reduced by means of regulation, non-exhaust emissions are currently uncontrolled and their importance is destined to increase and become the dominant urban source of particle matter by 2020. Nevertheless, current knowledge on the non-exhaust emissions is still limited. This is an essential book to researchers and advanced students from a broad range of disciplines, such as public health, toxicology, atmospheric sciences, environmental sciences, atmospheric chemistry and physics, geochemistry, epidemiology, built environment, road and vehicle engineering, and city planning. In addition, European and local authorities responsible for air quality and those in the industrial sectors related to vehicle and brake manufacturing and technological remediation measures will also find the book valuable.

Aeromicrobiology provides a detailed and systematic analysis of the microbial communities and toxins collectively called bioaerosols that can be found in air. It provides information on the basics of Aeromicrobiology, the fate and transport of microorganisms in air, and the fundamental differences between intramural and extramural Aeromicrobiology. Leaning heavily on the current state of science, detailed information on the sampling and analysis of bioaerosol samples is provided. Subsequent chapters comprehensively discuss various airborne microbial groups and toxins, while the final chapter is dedicated to bioaerosol control strategies, biosafety, and biosecurity. There are limited resources on Aeromicrobiology. In rare instances where there are resources on Aeromicrobiology, they are often restricted to chapters in books or even supplementary materials. The emergence of new airborne pathogens, the aerosolization of microorganisms hitherto believed not to be airborne, and the proliferation of technologies for sampling, analysis, and control of bioaerosols makes it imperative for this title, which streamlines and succinctly presents the new body of knowledge in the field. Leans heavily on current state-of-the-art technologies used in sampling and analysis of bioaerosol samples such as metagenomics and sensor-based, hybrid technologies, among others Dedicates considerable attention to airborne and droplet-borne viruses, against the background of SARS-CoV-2 and related pathogens Comprehensively attends to regulatory aspects of bioaerosol control, highlighting various policies and regulations aimed at achieving biosecurity and curbing bioterrorism Helps researchers and policy makers in various fields who are often confronted with the need for basic information delivered in seamless style without loss of essential content

Download Integration of Biogenic Emissions in Environmental Fate, Transport, and Exposure Systems in PDF, Epub, and Kindle

Biogenic emissions include a major, but highly uncertain, source of volatile organic compounds (VOCs) and bioaerosols that are emitted in the atmosphere. These two groups are involved as direct or indirect offenders of human health when transported during photochemical episodes and allergy seasons. Biogenic hydrocarbons are a significant fraction of the total VOC emission inventories for the United States and contribute to the formation of tropospheric ozone. Bioaerosols, including pollens, spores, and fungi are emitted seasonally and can lead to asthma exacerbation, irritation of the upper respiratory tract, and allergic response to a large portion of the population. Although all applications of photochemical modeling in a regulatory setting require the quantification of biogenic hydrocarbons, bioaerosols are currently not incorporated in the urban airshed models. Furthermore, the current biogenic emission estimation models and urban airshed models use low-resolution data for estimating vegetation biomass and VOC emissions. In this study, the geographical information systems ArcInfo and ArcMap were used to construct a high resolution, spatially accurate vegetation biomass and biogenic emissions database for the Northeast United States region. A number of sources of data on vegetation cover parameters were evaluated, and the final mappings incorporated information from the MODIS satellite instrument. Perl and MATLAB were used to interface the CMAQ photochemical model and the improved database aggregate. In addition, a pollen emission model that uses the same geodatabase components was developed for the same region. The two-fold aim of this study is to extend the common framework for additional biogenic emissions while improving the current methodologies for estimating biogenic VOCs. The methodologies developed in this work are presented along with the final composite geodatabase applications. The strong dependence of biogenic emissions on the spatial distribution of vegetation species made the use of a GIS an ideal method for improving biogenic emission estimates. Modifications in related portions of the CMAQ model were necessary in order to include these additional sources. Finally, this research identifies uncertainties associated with biogenic model structure and resolution with application to photochemical air quality modeling.
