The mechanism of atmospheric organic aerosol formation in the interaction of the aldehydes emitted by plants with typical urban air pollutants has been investigated. The kinetics of aerosol formation in the aldehyde vapour was studied under laboratory conditions, and the effect of ozone and nitrogen oxides on the rate and mechanism of condensable product formation was determined. The chemical nature of the terminal groups of a growing organic chain was determined to change in the presence of increased ozone concentration. The effect of biogenic aldehydes on the reduction of polluted urban air toxicity was assessed. The field measurements were carried out, revealing the role of vegetation in the reduction of toxic action of anthropogenic air pollutants.
Дульцева et al. (Fri,) studied this question.
