南宁市油毡厂生产过程中无任何“三废”污染预防措施,所排放的烟尘废气严重污染环境。为此,我们于1982年对该厂下风侧空气中的苯并(a)芘和人群肿瘤进行了调查。 1.大气中苯并(a)芘含量:本次共测定130个飘尘样品,检出率是93.85％。年平均日浓度(G):污染区为0.3026μg/100m~3,对照区为0.1946μg/100m~3,经统计学处理,差异有极显著性意义。厂区内部苯并(a)芘年日平均浓度为4.1932μg/100m~3,最高日浓度达75.0836μg/100m~3。距厂区
Nanning felt plant in the production process without any “three wastes” pollution prevention measures, the emissions of soot gas serious pollution of the environment. To this end, we conducted a survey of benzo (a) pyrene and human tumors in the leeward air of the plant in 1982. 1. Atmospheric benzo (a) pyrene content: A total of 130 floating dust samples were measured, the detection rate was 93.85%. The annual average daily concentration (G): the pollution area was 0.3026μg / 100m ~ 3, the control area was 0.1946μg / 100m ~ 3, the difference was statistically significant. The annual average concentration of benzo (a) pyrene in the plant was 4.1932μg / 100m ~ 3, and the highest daily concentration was 75.0836μg / 100m ~ 3. From the factory
