air pol·lu·tion

contamination of air by smoke and harmful gases, mainly oxides of carbon, sulfur, and nitrogen, as from automobile exhausts, industrial emissions, or burning rubbish.
See also: smog.

air pollution

The presence in the air of substances suh as carbon monoxide (CO), NO2, ozone, particulate matter, and SO2, which are byproducts of human activities, and which have an adverse effect on health. Fine (diameter ≤2.5 µm) particles are derived primarily from the combustion of fossil fuels in transportation, manufacturing, and power generation, and are mixed with soot, acid condensates, nitrate and sulfate particles, and may pose a greater risk to health as they are generally more toxic and can be inhaled deeply into the lungs; there is a significant association between fine particulate air pollution and deaths from cardiopulmonary disease, lung cancer, and other causes.
Health effects of air pollution Respiratory complaints, restricted activity, chest discomfort, sore throats, eye irritation; CO and ozone are linked to heart malformations and heart valve defects.

In a similar study at Dar-es-Salaam City, Tanzania, elevated level of NO2, CO and suspended particulate matter were reported at residential areas in the morning and evening time due to increased traffic flow and substantial domestic heating, where activities pattern and emission from mobile sources confirmed the elevated level of air pollutants at residential area(Jackson, 2009).

Therefore, we consider a method of combining several air pollutants and investigate the relation between our formed multi-pollutant exposure index--which we call the Health Air Study Index (HASI)--and public health.
Even a weak association between air pollution and diabetes mellitus would be important because of widespread exposure to air pollutants and the high prevalence of diabetes mellitus at population level.

Carbon is a major air pollutant, and air pollution is a costly problem in many urban areas of the United States, contributing to lung, throat, and eye irritation; respiratory and heart disease; and cancer.
The ozone, she pointed out, was a secondary air pollutant, formed by reactions between volatile organic compounds and nitrogen oxides.
EPA's proposed delisting of MEK as a hazardous air pollutant does not affect other ways this chemical will be regulated, however, it will continue to be regulated as a VOC because of its contribution to smog.
