Concentrations of benz(a)pyrene (BP) and 15 other polycyclic aromatic hydrocarbons (PAH) in soil with forage plants (lucerne) irrigated by biologically purified mixed domestic and industrial (coke-chemical) sewage from collection pond did not exceed those in control soil (irrigated by relatively clean fresh water) and were lower than in nonirrigated one, which is due, probably, to PAH oxidation by soil-proper microflora activated in humid soil polluted by PAH. BP content in control and experimental samples of lucerne coincide within +/- 25% limits.
用收集池中的生活和工业（焦化）混合生物净化污水灌溉种植有饲料植物（苜蓿）的土壤中，苯并(a)芘（BP）和其他15种多环芳烃（PAH）的浓度未超过对照土壤（用相对清洁的淡水灌溉）中的浓度，且低于未灌溉土壤中的浓度，这可能是由于PAH污染的潮湿土壤中活化的土壤固有微生物群对PAH进行了氧化。对照和实验苜蓿样品中的BP含量在±25%的范围内相符。
