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.

Though Hertz-Picciotto says the study moves "one step closer to identifying bad actors," the researchers were not able to definitively screen out air pollutants that truly are not risk factors for ASDs.
where C = C(x, y, z, t) is the air pollutant concentration at point (x, y, z) in Cartesian coordinates and at time t (kg/[m.sup.3]).
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).
also showed that [PM.sub.10] has different emission sources from that of other air pollutants by comparing various air pollutants in Leeds UK and Makkah, Saudi Arabia.
The HASI values encapsulate health effects of 6 air pollutants, by combining the rates of health aggravation (slopes [beta](i)) with the current daily levels of the pollutants.
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.
In a statement, the civic body added that a World Health Organisation study found the number of deaths attributed to diseases caused by air pollutants in Austria, Switzerland and France has exceeded 21,000 per year.
Air pollutants investigated included carbon monoxide, nitrogen dioxide, particulate matter (PM10 and PM2.5), sulfur dioxide and ozone.
Air pollutants included carbon monoxide, nitrogen dioxide, particulate matter (PM10 and PM2.5), sulphur dioxide, and ozone.
Whilst previous studies had examined air pollution and ASD, they generally had not examined gender differences in the relationship between ASD and air pollutants. In this study most of the air pollutant associations with ASD were stronger for boys than girls however this must be interpreted with caution as a smaller number of girls with ASD were included in the analysis.
The six common air pollutants, or criteria pollutants, that EPA currently regulates are particulate matter, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead.
Der-Jen Hsu and colleagues from the National Kaohsiung First University of Science and Technology (Taiwan) report that essential oils used in aromatherapy may emit potentially harmful indoor air pollutants such as volatile organic compounds (VOCs), the degradation of which by ozone present in the air can produce small, ultrafine byproducts known as secondary organic aerosols (SOAs), which may cause eye and airway irritation.
