本钢焦化厂有50年以上的历史。接触毒物的工人癌症死亡率显著高于对照组。作者于1981—1983年在12个点采了空气样品,包括(1)主要污染源工作场所,(2)距污染源不同距离,(3)居民区,(4)清洁对照区。用薄层荧光法及高压液相色谱法共分析了近200个样品。清楚地了解了苯并(a)芘浓度的变化规律,扩散范围及对厂区及居民区的影响。与国内外同类工厂相比,此焦化厂的污染属于中等水平。
Benxi Iron and Steel Coking Plant more than 50 years of history. The cancer death rate of workers exposed to poison was significantly higher than that of the control group. The author collected air samples at 12 points in 1981-1983, including (1) major sources of workplace pollution, (2) different distances from sources of pollution, (3) residential areas, and (4) clean control areas. Nearly 200 samples were analyzed by thin-layer fluorescence and high-pressure liquid chromatography. Clearly understand the change of benzo (a) pyrene concentration, the scope of diffusion and plant and residential areas. Compared with similar factories at home and abroad, the pollution of this coking plant belongs to the medium level.
