The National Research Council recommended both a risk- and performance-based multipollutant approach to air quality management. Specifically, management decisions should be based on minimizing the exposure to, and risk of adverse effects from, multiple sources of air pollution and that the success of these decisions should be measured by how well they achieved this objective. We briefly describ...

It is widely known that the railroad diesel locomotive engines emit significant amount of air pollutants. However, these engines are not equipped with any air pollutants reducing devices in Korea, resulting in the accumulative air pollution near the railroad. Because the pollutants emission from driving locomotive engines cannot be measured directly, the emission factors based on the amount of ...

The momentary maximum concentration of the most important air pollutants (nitrogen oxide, sulfur dioxide, carbon monoxide and dusts) was determined using the dispersion curves of the pollutants in the densely inhabited areas of Dâmboviţa County. In order to present the industry-wide potential impact of air pollutants on the population and on the environment, maps showing air pollution levels ha...

Background: Air pollution is a serious threat to children health. Given that children spend over 80% of their time indoors, understanding transport of pollutants from outdoor to indoor environments is important for assessing the impact of exposure to outdoor pollution on children health. The most common advice given during a smoke pollution episode is to stay indoors. How well this works depend...

Indoor air pollution (IAP) is a key contributor to the global burden of disease mainly in developing countries. The use of solid fuel for cooking and heating is the main source of IAP in developing countries, accounting for an estimated 3.5 million deaths and 4.5% of Disability-Adjusted Life Years in 2010. Other sources of IAP include indoor smoking, infiltration of pollutants from outdoor sour...

Paul Goldin – Avmor Director of Marketing and Customer Satisfaction According to Health Canada, Canadians spend close to 90% of their time inside either at home, at work, or in recreational environments. Most people, however, are unaware of the effects that poor indoor air quality can have on their health. The air inside a building carries much higher concentrations of pollutants than the air o...

conclusions results indicated that annular fluidized bed reactor’s adsorbers are useful techniques for vocs adsorption. comparison of two particle ranges indicates that in all concentrations and all flow rates of the experiments, smaller particle size adsorption are better. in superficial velocity above the minimum fluidization velocity, pressure drop of fluidized beds are less than the pressur...

Background and Objectives: Emission inventory of mobile sources is an essential element for studying the air quality. In order to support the development of public policies with an approach to reducing the overall mass emissions of air pollutants, the aim of the current study was preparation of a GIS based emission inventory of Karaj mobile sources air pollutants. Material and methods: In the p...
