摘要

摘要: 采用气相色谱对采自福建省21个茶园的土壤样本中的有机氯农药六六六(HCHs)和滴滴涕(DDTs)含量进行分析。结果表明,在被调查茶园土壤中,HCHs和DDTs均有不同程度检出,其中HCHs的残留总量为0.10μg.kg-1,DDT的残留总量为0.18μg.kg-1,HCHs以β-666和α-666为主,DDTs以pp-dde、pp-ddd和op-ddt为主。高海拔茶园土壤中的HCHs和DDTs残留量高于低海拔地区,同时发现残留量与茶龄呈负相关。从单因子污染指数和综合污染指数分析,土壤中HCHs和DDTs的残留量尚未超标,土壤总体处于无污染状态,符合自然土壤级别机制标准,适合茶树种植。

Abstract: The organochlorine pesticide residues(HCHs and DDTs) in the organic tea garden soil in Fujian were investigated by GC analysis.The results showed that HCHs and DDTs were detected at different levels among 21 tea garden soils.In addition,the residues total of HCHs was 0.10 μg·kg-1 with β-666 and α-666 as the most residues;the residues total of DDTs was 0.18 μg·kg-1 with pp-dde,pp-ddd and op-ddt as the most residues.Further,the HCHs and DDTs residues in high-altitude tea gardens were more than low-altitude tea gardens significantly and correlated with tea ages negatively,and single pollution index and synthetic pollution indices suggest that BHC and DDT residues are not exceeded and the soil is suitable for tea cultivation.
