环境中有机氯农药残留与女性乳腺癌

Correlation between Brganochlorines Pesticides Residues and Breast Cancer

以六六六(HCH)、滴滴涕(DDT)为代表的有机氯农药是我国最早大规模使用的农药,因其有累积性、不易降解,我国在1983年已禁止使用,然而,由于这2类农药在自然条件下很难降解等原因,在我国环境中至今仍有残留。这些残留的有机氯农药对人类和野生动物的健康存在巨大威胁。有机氯农药在我国城乡人群中存在不同程度的蓄积。人的乳腺癌与接触有机氯农药可能有联系,但至今尚未确定它们之间的因果关系。

Organochlorines pesticides are a diverse group of synthetic chemicals such as hexachlorocyclohexane（HCH） and dichlorodiphenyl-trichloroethane（DDT）. Although organochlorines pesticides has been banned in China since 1983, some organochlorine pesticides have accumulated and persisted within the environment. As a result, measurable amounts can still be found in＇human tissue. Because some organochlorine pesticides act as estrogen agonists, a possible association of breast cancer risk with organochlorine pesticides exposure has been hypothesized and investigated. The available evidence does not suggest an association between the residues of these chemicals and breast cancer.
