[Nitrosamine levels in the environmental air of several large cities]. / K voprosu o soderzhanii nitrozaminov v atmosfernom vozdukhe nekotorykh krupnykh gorodov.

Data of studies on the content of nitrosodimethylamine, nitrosodiethylamine and nitrogen oxides in the air medium of certain cities with different degrees of industrial development are presented in the paper. The dynamics of the concentrations of chemicals under study during the annual cycle is shown. A correlation between the content of those chemicals in the air medium and the main meteorological factor is established.
