Each of these vehicles must meet specific emissions targets before being allowed to obtain or renew vehicle registrations. Many of these programs are administered on the local and county level. For example, the Clean Air Car Check is a vehicle emissions-testing program for all vehicles registered in Lake and Porter counties in Indiana. The two ...
[15] [16] Lighter vehicles pollute less [15] and reducing vehicle kilometers traveled is another method of mitigating non-exhaust emissions. Reducing demand for private vehicle travel can be accomplished by various measures that increase the relative attractiveness of public transport and non-motorized modes relative to private vehicles.
For example, one would want to determine a geographic area's exposure to a dangerous air pollution, taking into account the various microenvironments and age groups. This can be calculated [102] as an inhalation exposure. This would account for daily exposure in various settings, e.g. different indoor micro-environments and outdoor locations.
Exposure to particulate matter of less than 2.5 micrometers in diameter led to significant changes in ROS levels, indicating that particulate matter exposure was a causative agent of oxidative stress in Tigriopus japonicus. [42] In addition to aquatic invertebrates, negative effects of particulate matter have been noted in mammals as well.
List of most-polluted cities by particulate matter concentration; 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
Particulates or atmospheric particulate matter (see below for other names) are microscopic particles of solid or liquid matter suspended in the air.The term aerosol refers to the particulate/air mixture, as opposed to the particulate matter alone, [1] though it is sometimes defined as a subset of aerosol terminology. [2]
Motor vehicle CO 2 emissions are part of the anthropogenic contribution to the growth of CO 2 concentrations in the atmosphere which according to the vast majority of the scientific community is causing climate change. [34] Motor vehicles are calculated to generate about 20% of the European Union's man-made CO 2 emissions, with passenger cars ...
The operation of any car results in non-exhaust emissions such as brake dust, airborne road dust, and tire erosion, which contribute to particulate matter in the air. [53] Particulate matter is dangerous for respiratory health. [54] [55] In the UK non-tailpipe particulate emissions from all types of vehicles (including electric vehicles) may be ...
