[The evaluation of the mutagenic activity of gaseous particles in the atmospheric air by using a microbiological test].
Total mutagen activity of a gas component in chemical pollutions of the atmospheric air in a number of industrially developed towns of Ukraine has been studied and assessed in a microbiological test on Salmonella typhimurium. The towns were chosen proceeding from the specificity of industry: metallurgical industry (Mariupol, Zaporozhye, Donetsk, Krivoi Rog, Makeevka); chemical industry (Cherkassy, Chernigov; Kremenchug, Severodonetsk, Lisichansk, Gorlovka, Rovno, Sumy) and conditionally control ones (Simferopol, Sevastopol, Nikolaev, Poltava, Zhitomir). The air samples, 100 m3, have been taken in each town weekly during a month by special absorbers of Polysorb-2 type. The extraction of chemical matters from absorbers was carried out by traditional methods. Chemical matters were dissolved in dimethyl sulphoxide and tested for its ability to induce the gene mutations. The studies have shown that the atmospheric air samples from the group of "metallurgical" towns prove the mutagen activity, classified as the "middle" one (the number of revertant colonies in the experiment exceeded the control 10.3 to 22.2 times). The mutagenicity of "chemical" towns was on the level of "middle" and "weak", that of conditionally control ones was on the level of "weak" only.
