WebTranscript NARRATOR: This brownish haze, photochemical smog hanging over Los Angeles, results from a combination of factors: the city's plentiful sunshine, high density of automobile traffic, and frequent temperature inversions that trap polluted air. WebPhotochemical smog has a number of negative effects on the environment and human beings. The chemicals contained within it, when combined with hydrocarbons, form …
Photochemical Smog - Mrs. Reed Fresno High school
WebPhotochemical Smog General Photochemical smog consists of mix-tures of gaseous and particulate (aero-sol) products resulting from atmospheric photochemical reactions of gases evolved primarily from the combustion of organic fuels; it is characterized by the presence of high atmospheric oxidant levels.1-3 In the photochemical smog-forming WebThese three main components of photochemical smog cause necrosis, spot-like lesions, chlorosis by ozone, and injuries on the lower surface of leaves by PAN and NO/sub 2/. The existence of species specificity of susceptibility of plants against various component of photochemical smog was also described. Authors: Matsushima, J. mama they say im a terrorist gacha meme

WebTerrible Effects of Smog on Humans, Plants and Animals. 1. Effects on Human Health. Smog is composed of a mixture of air pollutants that can endanger human health. Various human health problems such as emphysema, asthma, chronic bronchitis, lung infections, and cancers are caused or exacerbated by the effects of smog. WebPhotochemical smog can be severe in the Los Angeles basin of the California coast (see Fig. 17.7).Commuting in Los Angeles requires many cars, which produce high emissions of NO x and hydrocarbons. At certain times of the year, particularly spring and fall, weather conditions in this area are dominated by subtropical high pressure with clear, calm air … WebGround-level ozone, on the other hand, is a pollutant and a primary ingredient of smog. It forms when volatile organic compounds, or VOCs, and nitrogen oxides participate in chemical reactions in the presence of sunlight. VOCs: Carbon-containing compounds that easily evaporate at room temperature and enter the surrounding air. mama they say im a terrorist
