A method for the fluorimetric determination of benzo(a)pyrene content is presented consisting of classical clean-up steps. The method was applied to microbial biomasses and different feed stuffs. The investigated yeasts grown on carbohydrates keep the limit of 5 ppb benzo(a)-pyrene recommended by the IUPAC. Yeast samples of the VEB Petrolchemisches Kombinat Schwedt grown on petroleum distillate have a constant quality with benzo(a)pyrene contents at 1 ppb. A selection of bacterial biomasses shows also contents less than 5 ppb. The benzo(a)pyrene contents of biomasses cultivated on liquid manure exceed the given limit.
介绍了一种荧光法测定苯并(a)芘含量的方法，该方法包括经典的净化步骤。该方法应用于微生物生物质和不同的饲料。在碳水化合物上生长的被研究酵母的苯并(a)芘含量保持在国际纯粹与应用化学联合会推荐的5 ppb限量内。在石油馏出物上生长的VEB施韦特石油化学联合企业的酵母样品质量稳定，苯并(a)芘含量为1 ppb。一些细菌生物质的含量也低于5 ppb。在液体粪肥上培养的生物质的苯并(a)芘含量超过了规定的限量。
