BACKGROUND Airborne emissions from numerous point, area, and mobile sources, along with stagnant meteorologic conditions, contribute to frequent episodes of elevated air pollution in Houston, Texas. To address this problem, decision makers must set priorities among thousands of individual air pollutants as they formulate effective and efficient mitigation strategies. OBJECTIVES Our aim was to...

Projecting a hazardous air pollutant (HAP) emission inventory to future years can provide valuable information for air quality management activities such as prediction of program successes and helping to assess future priorities. We have projected the 1999 National Emission Inventory for HAPs to numerous future years up to 2020 using the following tools and data: the Emissions Modeling System f...

A brief history of air pollution management in Canada is provided in this chapter. Whether the issue be acid rain, ground level ozone, particulate matter, air toxics, or emergency releases of air pollutants, Canada has traditionally built a management approach on: strong science; a desire to move in a similar direction to our southern friends, the U.S.A.; connections to the rest of the world; a...

Pollution prevention for the textile industry is reviewed, including a brief summary of present practices and an analysis of future needs and opportunities. Barriers and facilitating factors are identified. Introduction Thb US textile industry has a major impact not only on the nation’s economy but also the economic and environmental quality of life in many communities. In several states, texti...

One-atmosphere three-dimensional (3-D) grid models are now being widely used to predict the impacts of emission controls on the atmospheric concentrations and deposition of pollutants such as ozone (O3), fine particulate matter (PM2.5), mercury (Hg) and other air toxics. Such a gridbased approach necessarily averages emissions within the volume of the grid cell where they are released. This ave...

Workers and fence-line communities have been the first to benefit from the substantial reductions in toxic chemical use and byproducts in industrial production resulting from the Massachusetts Toxics Use Reduction Act (TURA). As TURA motivates reformulation of products as well as retooling of production processes, benefits could extend more broadly to large-scale reductions in everyday exposure...
