説明

type:text

Nitrogen dioxide is known to be an air pollutant inducing photochemical smog, in which reactive species such as an oxygen atom O (3P), ozone and hydroxyl radical etc. could take part in its appearance. Aromatic hydrocarbons released from automobiles into the troposphere underwent a ring fission leading to glyoxals (α-diketones) and the hydroxyl-nitration of the ring leading to nitrophenols under the circumstances. Their formation could be attributed to the action of the above active species. Moreover, α-diketones or suspended particulates, one of air pollutants, caused the photo-epoxidation, for example, converting aldrin into the corresponding epoxide, dieldrin.
