有机氯农药六六六和DDT具有一定的毒性,由于其化学性质稳定,不易分解,长年广泛地使用后,会对环境造成污染并在食品中残留,从而影响到人们的安全。因其有亲脂性,所以也可以在体内蓄积,故目前许多国家把有机氯农药在人体脂肪、乳汁和血液中的蓄积作为环境污染的重要指标。 1977年我室曾采集了20份手术病人和死胎的脂肪、肝脏和脑组织,用薄层层析法测定六六六和DDT含量,检出率分别为50％和20％。为了探讨广西地区人体中有机氯农药蓄积水平,1980年我们采集人体脂肪101份,用气相色谱法进行测定,现报导如下:
Organochlorinated pesticides BHC and DDT have certain toxicity. Due to their chemical stability, they are not easily decomposed. After being widely used for many years, they will pollute the environment and remain in the food, thus affecting people’s safety. Because of its lipophilicity, it can also accumulate in the body, so many countries present the accumulation of organochlorine pesticides in human body fat, milk and blood as an important indicator of environmental pollution. In 1977, we collected 20 pieces of fat, liver and brain tissue from surgical patients and stillbirths. The content of BHC and DDT was 50% and 20% respectively. In order to investigate the accumulation of organochlorine pesticides in Guangxi, 101 human fat samples were collected in 1980 and determined by gas chromatography. The results are reported as follows:
