The California Air Resources Board found in studies that 50% or more of the air pollution in Southern California is due to car emissions. [ citation needed ] Concentrations of pollutants emitted from combustion engines may be particularly high around signalized intersections because of idling and accelerations.
Vehicle emissions control is the study of reducing the emissions produced by motor vehicles, especially internal combustion engines.The primary emissions studied include hydrocarbons, volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen oxides, particulate matter, and sulfur oxides.
Cars produce numerous harmful air pollutants in their exhaust such as NO x, particulate matter and ground-level ozone (indirectly). [9] Additionally, as car tires wear down, they shed the materials they are made of into the air as particulate pollution. [ 10 ]
A new study says that air pollution — specifically, the kind caused by car exhaust — may be a significant cause of rising rates of autism in children.. Exposure to nitric oxide (NO)— which ...
A study just published in an American Heart Association journal links atherosclerosis -- hardening of the arteries -- to car exhaust. The diesel exhaust fumes robbed what is generally known as ...
The Clean Air Act of 1963 (CAA) was passed as an extension of the Air Pollution Control Act of 1955, encouraging the federal government via the United States Public Health Service under the then-Department of Health, Education, and Welfare (HEW) to encourage research and development towards reducing pollution and working with states to establish their own emission reduction programs.
Mobile source air pollution – Air pollution emitted by motor vehicles, airplanes, locomotives, and other engines; Planned obsolescence – Policy of planning or designing a product with an artificially limited useful life; Remote work – Employees working from any location; Service life – Period of time where an object can fulfill a function
The action is a huge win for California's fight against climate change. It could also pressure automakers to accept tougher national car pollution rules.
