Abstract : Study of cases of intense air pollution shows that a part of them is related to periods of extended fogs. The harmful effect of smoke and gaseous admixtures is revealed more sharply in fog than in other weather conditions: an unpleasant feeling from them is increased, the presence of admixtures in fogs furthermore decreases the visibility, etc. One notes a reverse effect when the presence of smoke contributes to the condensation of the atmospheric moisture. In this manner, a mutually increasing effect of smokes and fogs occurs. The report presents the estimates of the influence of river fogs (the theory of which is developed by Berliand and Onikul, on the distribution of gaseous admixtures. (Author)
