发展中国家在实施公共卫生计划中,使用有机氯杀虫剂是十分重要的。因此,有必要在局部使用现场条件下,评价人体对这种化合物的反应。评价短期(16周)接触六六六的后果,分别测定疟疾喷洒员接触六六六前、后血清六六六的浓度,并比较以前有、无六六六职业接触史两者的结果。以前无接触史者在本次接触后血清六六六浓度有5倍增高,显著高于有接触史者的增高(3倍)。不管其过去有无接触史,接触16周后,全部观察对象血清中六六六浓度几乎一致。
The use of organochlorine pesticides in developing countries in the implementation of public health programs is very important. Therefore, it is necessary to evaluate the human body’s response to such compounds under the conditions of local use. To evaluate the short-term (16 weeks) exposure to the effects of 666, and to determine the serum levels of BHC before and after exposure to 666 malaria patients, and to compare the results of previous and non-HLS occupational exposure history. In the past, there was a 5-fold increase in serum BHC concentration in this contact-free group before the current exposure, which was significantly higher than that in those with exposure history (3-fold). Regardless of their past history of exposure, after 16 weeks of exposure, the concentrations of BHC in sera of all subjects were almost the same.
