A view of Los Angeles covered in smog. Pollution in California relates to the degree of pollution in the air, water, and land of the U.S. state of California.Pollution is defined as the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a faster rate than it can be dispersed, diluted, decomposed, recycled, or ...
The California Air Resources Board (CARB or ARB) is an agency of the government of California that aims to reduce air pollution.Established in 1967 when then-governor Ronald Reagan signed the Mulford-Carrell Act, combining the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board, CARB is a department within the cabinet-level California Environmental Protection Agency.
The San Joaquin Valley Air Pollution Control District is the primary regulator for the region and has taken various actions to improve air quality and meet the standards of the CAA. The District adopted a PM 10 Attainment Demonstration Plan in 2006, an Ozone Attainment Demonstration Plan in 2007 and a PM 2.5 Attainment Demonstration Plan in ...
Atmospheric chemistry is a branch of atmospheric science that studies the chemistry of the Earth's atmosphere and that of other planets. This multidisciplinary approach of research draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology, climatology and other disciplines to understand both natural and human-induced changes in atmospheric ...
Total atmospheric mass is 5.1480 × 10 18 kg (1.13494 × 10 19 lb), [42] about 2.5% less than would be inferred from the average sea-level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain. Atmospheric pressure is the total weight of the air above unit area at the point where the ...
The South Coast Air Quality Management District's governing board voted 9-1 to effectively phase out certain kinds of natural-gas-fired water-heating equipment in homes and businesses across its ...
Argon constitutes 0.934% by volume and 1.288% by mass of Earth's atmosphere. [23] Air is the primary industrial source of purified argon products. Argon is isolated from air by fractionation, most commonly by cryogenic fractional distillation, a process that also produces purified nitrogen, oxygen, neon, krypton and xenon. [24]
A recent study conducted by the University of California Davis found that adding nitrogen fertilizer to soil in California is contributing 25 percent or more to state-wide NO x pollution levels. [18] When nitrogen fertilizer is added to the soil, excess ammonium and nitrate not used by plants can be converted to NO by microorganisms in the soil ...
