有机氯农药是一类高残留农药,在环境中性质稳定,残留期长,并容易通过食物链在生物体内富集。有关这类农药对人类胎儿影响的研究较少。为此,我们以有机氯农药的使用和鸡蛋有机氯残留量为环境有机氯暴露的指标,进一步分析了它们与不良妊娠结局的关系。研究对象在湖北农村选择1个棉产区和1个稻产区作为研究地区。以研究地区户口在册、1989年1月1日～12月31日期间出现的任何妊娠结局的妇女作为研究对象。妊娠结局终点指标的分类及定义参考文献,农药销售及使用情况是从当地生产资料销售部门和农民家中调查所得,两地区鸡蛋
Organochlorine pesticides are a group of highly residual pesticides that are stable in nature and of long duration and are readily enriched in the body of organisms through the food chain. There is little research on the influence of these pesticides on human fetuses. For this reason, we further analyzed their relationship with adverse pregnancy outcomes based on the use of organochlorine pesticides and residues of organic chlorine in eggs as indicators of environmental organochlorine exposure. The research object chooses 1 cotton producing area and 1 rice producing area in Hubei rural area as the research area. To study the regional accounts in the book, January 1, 1989 to December 31 period occurred during any pregnancy outcome of women as the research object. Classification and definition of the end of pregnancy outcome indicators References, sales and use of pesticides from the local means of production sales department and farmers surveyed the home, the two regions of eggs
