The study was designed to analyse air pollution by 3,4-benz(a)pyrene released together with exhaust gases in 3 underground mines where self-propelled machines with diesel engines are used. Concentration levels for 3,4-BP have been identified in air, dust, sweeping away and scraping off the walls of the mine working surface. It is demonstrated that in a great number of samples 3,4-BP concentration exceeds MAC. A technique for 3,4-BP air sampling and analysis has been studied by means of liquid chromatography with ultraviolet detection. Hygienic recommendations on decreasing 3,4-BP release into the mine air are set forth.
