[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.
Transportation emissions also include sulfur dioxides and particulate matter but in much smaller quantities than the pollutants mentioned previously. The nitrogen oxides and volatile organic compounds can undergo a series of chemical reactions with sunlight, heat, ammonia , moisture, and other compounds to form the noxious vapors, ground level ...
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 ...
The authors emphasized that vehicles contribute merely about 1% to California’s total direct fine particulate matter emissions, with a significant portion originating from older models, as per ...
Life and particulate organic matter in the ocean have fundamentally shaped the planet. On the most basic level, particulate organic matter can be defined as both living and non-living matter of biological origin with a size of ≥0.2 μm in diameter, including anything from a small bacterium (0.2 μm in size) to blue whales (20 m in size).

United States Light-Duty Vehicle, Light-Duty Truck, and Medium-Duty Passenger Vehicle—Tier 2 Exhaust Emission Standards (for Bin 5) [4] Component Emission Rate Annual pollution emitted NMOG (Volatile organic compounds) 0.075 grams/mile (0.046 g/km) 2.1 pounds (0.95 kg) Carbon Monoxide 3.4 grams/mile (2.1 g/km) 94 pounds (43 kg) NO X
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 ...
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.
