The levels of dust and chemical pollutants in the working environment of Tbilisi municipal transport workers were examined. Methods used in hygienic practice were applied to analyze air samples. test in total was conducted to measure the concentration of dust in the air and samples were collected with air analyzers. The toxicity levels in the surrounding environment of the municipal motor vehicle drivers, as well as technicians (welders, electricians, turners, tinsmiths, electric arc welding). It was established that the toxicity of the air in the municipal transports and technical service establishments fluctuates between certain levels. The highest dust levels were found in the working zone of the driver, with dust levels twice accepted levels. Working conditions at this specific zone were identified as 3.1 class. Workplaces in different service stations were also classified in the same group, with dust levels 1.6 times higher than normal. In total 5 workplaces were given level 3.1 classification. Only the workplace of a tinsmith was classified as a level 2 acceptable hazard. The concentration of dust and toxic chemicals in the environment of municipal transport employees is lower than acceptable levels, but long-time exposure to these agents affects the health of individuals and may cause subclinical health effects, even if the disease does not fully manifest.
