The purpose of this study was to make a quantitative assessment and prediction of the degree of ambient air benzo(a)pyrene pollution in Bishkek and to develop environmental PAH reduction measures. Analysis of the data shows that the greatest ambient air benzo(a)pyrene pollution was observed in the central and northern parts of the town (up to 46 maximum allowable concentrations - MAC), the bedroom communities situated in the southern part of the town can be described as conditionally clean (up to 10.3 MAC). The main sources of pollution are motor transport and energy-fuel enterprises. Prediction analysis indicates a linear increase in annual rates. BaP accumulation and decomposition was also found to be periodic and, if appropriate measures are not undertaken, BaP concentrations might increase up to 80 MAC in a short time.
本研究的目的是对比什凯克市环境空气中苯并(a)芘的污染程度进行定量评估和预测，并制定减少环境中多环芳烃的措施。数据分析表明，该市中部和北部的环境空气中苯并(a)芘污染最为严重（最高可达46倍最大允许浓度——MAC），位于该市南部的居住区可描述为条件清洁（最高可达10.3倍MAC）。主要污染源是机动车交通和能源燃料企业。预测分析表明年发生率呈线性增长。还发现苯并(a)芘的积累和分解具有周期性，若不采取适当措施，苯并(a)芘浓度可能在短时间内增至80倍MAC。
