查询词典 dichlorodiphenyltrichloroethane

In this study, dichlorodiphenyltrichloroethane, hexachlorocyclohexane and chlordane were measured in 23 aquatic organism samples collected from Deep Bay, South China. Results showed that, the concentrations of DDTs, HCHs and CHLs in fishes were in the range of 1.84~286.83, 0.08~1.85 and 0.45~118.81ngg^(-1), respectively.

This study was organized in three parts. Part One: The ecological study on the relationship between environmental organochloride pollution and the incidence rate of colorectal cancer. In this part, the incidence rate of colorectal cancer was determined from the tumor registry system of Jiashan County, a highest incidence area of colorectal cancer. The soil and rice samples were collected according to the incidence rate of colorectal cancer and the geographic position of the east, west, south, north and center. The concentrations of dichlorodiphenyltrichloroethane, hexachlorocyclohexane, polychlorinated biphenyl and sodium pentachlorophenate were detected in laboratory.

共分三个部分：第一部分环境有机氯污染与结直肠癌发病率关系的生态学研究利用结直肠癌高发区嘉善县肿瘤登记报告系统，确定各乡镇结直肠癌各年度发病率；按各乡镇结直肠癌发病率的高、中低及地理位置东、西、南、北、中等结合采集土壤和大米样品，检测其DDT、HCH、PCBs及Na-PCP的含量；对这些有机氯污染指标值与相应的结直肠癌发病率之间作相关分析等统计学处理。

Objective: In order to provide sensitive and reliable technique for the study of the relationship between enviromental estrogens and diseases, analytical methods for three kinds of representative environmental estrogens such as mycotoxins (zearalenone and its metabolites, aflatoxin B_1 and ochratoxin A), persistent pesticide pollutants (hexachlorocyclohexane and dichlorodiphenyltrichloroethane) and industrial chemicals (bisphenol A and 4-nonylphenol) with chromatography were to develop.

目的：选择三种有代表性的环境雌激素：真菌类毒素(玉米赤霉烯酮及其代谢物及赭曲霉毒素A、黄曲霉毒素B_1)、农药类持久性污染物(666、DDT)和化工原料类雌激素为对象，分别研究它们的检测方法，为监控环境激素和研究它们与疾病之间关系提供灵敏、可靠的分析方法和实验依据。
