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.
