贵州湄潭茶产区土壤中残留六六六、滴滴涕的检测研究

A Research on the Detection of Benzene Hexachloride and Dichloro-diphenyl-trichloroethane(DDT) Residues in the Soil of Tea Production Area in Meitan County,Guizhou Province

采用气相色谱法对贵州省遵义市湄潭县6个茶园产区土壤中有机氯农药六六六、滴滴涕的残留进行了分析。其结果表明,茶园产区一、二、四、五、六的土壤样品均未检测出六六六和滴滴涕的存在,而在茶园产区三土壤样品检测出六六六,残留量小于0.05mg/kg。分析结果表明6个产区的土壤品质较好,能保证茶叶质量的可靠性。

Detection of benzene hexachloride and dichloro-diphenyl-triehloroethane （DDT） residues in the soil of six tea production area in Meitan county, Guizhou province is performed by gas chromatography （GC）. The results show that no benzene hexachloride and DDT ingredients was detected in the first, second, fourth, fifth and sixth tea production area, while less than 0.05% of benzene hexachloride was detected in the third tea production area and the detection rate is about 97.6%. The primary research indicates that the quality of tea produced in these six areas is reliable.
