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.
该研究旨在分析3个使用柴油发动机自行式机械的地下矿井中，与废气一同排放的3,4-苯并(a)芘所造成的空气污染。已测定了矿井工作面空气中、粉尘中以及巷道壁清扫物和刮落物中的3,4-苯并芘浓度水平。结果表明，大量样品中的3,4-苯并芘浓度超过了最大允许浓度。研究了采用带紫外检测的液相色谱法对3,4-苯并芘进行空气采样和分析的技术。并提出了减少3,4-苯并芘向矿井空气中排放的卫生学建议。
