BTXE-Immissions (benzene, toluene, ethylbenzene, xylene) were measured in 32 flats in the neighbourhood of 12 filling stations in Frankfurt on the Main. Mean benzene-concentration in the indoor air nearby filling stations was 10.2 micrograms/m3, whereas in reference flats 5.6 micrograms/m3 were measured. Maximum levels were 22.4 micrograms/m3 and 8.0 micrograms/m3. Indoor air levels were slightly higher than outdoor air contaminations. High Toluene-concentrations were not caused by the filling stations but by other commercial enterprises, such as paint shops. Mean ethylbenzene or xylene-concentrations in the neighbourhood of filling stations did not differ from the concentrations measured in the reference flats. Because of the cancerogenicity of benzene the benzene-contaminations in the neighbourhood of filling stations have to be lowered. The newly established German law to prevent gas leakage in filling stations will lead to some improvement in the future.
在美因河畔法兰克福12个加油站附近的32套公寓中，测量了BTXE污染物（苯、甲苯、乙苯、二甲苯）。加油站附近室内空气中苯的平均浓度为10.2微克/立方米，而在对照公寓中测得的浓度为5.6微克/立方米。最高水平分别为22.4微克/立方米和8.0微克/立方米。室内空气水平略高于室外空气污染水平。高甲苯浓度并非由加油站造成，而是由其他商业企业，如油漆店导致的。加油站附近乙苯或二甲苯的平均浓度与对照公寓中测得的浓度没有差异。由于苯具有致癌性，必须降低加油站附近的苯污染。德国新颁布的防止加油站气体泄漏的法律未来将带来一定改善。
