30 Αυγ 2013 · In this review paper, we discuss the causes, impacts of air pollution and its management that result in sustainable development.
This article briefly describes major air pollu-tants, by presenting their sources, dispersion, transformation, immission (concentration of air pollutants in the ambient air), and potential effects on health and the environment.
1 Νοε 2018 · Air quality encompasses the here-and-now of pollutant emissions, atmospheric transformations and their direct effect on human and ecosystem health. Climate change deals with the drivers leading...
The authors of this book include a chemist (Donald L. Fox), a meteorolo-gist (D. Bruce Turner), and a mechanical engineer (Richard W. Boubel). This 1:1:1 ratio has some relevance in that it approximates the ratio of those pro-fessionally involved in the field of air pollution. In the environmental protec-
An instrumental variables approach based on thermal inversions is used to identify the causal impact of air pollution on economic activity. The estimates show that a 1μg/m3 increase in PM2.5 concentration (or a 10% increase at the sample mean) causes a 0.8% reduction in real GDP that same year.
Pollutants can be classified as primary or secondary. Primary pollutants are substances that are directly emitted into the atmosphere from sources. The main primary pollutants known to cause harm in high enough concentrations are the following: • Carbon compounds, such as CO, CO 2, CH 4, and VOCs • Nitrogen compounds, such as NO, N 2 O, and ...
permet d’envisager une réduction des impacts sanitaires de la pollution atmosphérique. De nombreuses études présentées dans la littérature se basent sur les émissions des polluants de l’air qui sont estimées de façon théorique en sommant les quantités en tonnes de polluants rejetés dans l’atmosphère par les activités ...
