Air Pollution is caused by emissions from pollution sources such as motor vehicles, power plants and industrial facilities. Air pollution levels are also affected by weather conditions. Under stagnant weather when pollutants do not disperse effectively, air pollution sometimes can reach high levels. Those with existing heart or respiratory illnesses may be affected by the air pollution. In addition to continuing our efforts to combat air pollution, we also provide the latest hourly Air Pollution Index to let you know about the quality of the air you are breathing.
