• 中文摘要： 本研究探討有機氯化烴殺蟲劑及其代謝物包括ρ,ρ'-DDT, ρ,ρ'-DDD, ρ,ρ'-DDE, γ-BHC, 阿特靈，地特靈，飛佈達及飛佈達氧化物在臺灣茶園土壞中之殘留量。土壤樣品分別於民國六十六年採自六縣市之十五鄉鎮及於民國七十三年採自十縣市之四十六鄉鎮，共有來自一百餘地點之土壤樣品供做分析。 雖然此類有機氯化烴殺蟲劑已被禁止使用多年，但仍可被檢出在環境中殘留。其在茶園土壤中之平均殘留量自民國六十六年至民國七十三年有減少趨勢，γ-BHC自5.64減至0.06 ppb（檢出樣品百分率由28增至91%），阿特靈自97.54減至1.10 ppb（檢出樣品百分率由96增至100%），ρ,ρ'-DDE自35.91減至1.00 ppb（檢出樣品百分率由98增至99.5%)，地特靈自17·41減至0.28 ppb（檢出樣品百分率由88增至93·5%），ρ,ρ'-DDT自30.17減至3.42 ppb（檢出樣品百分率由82增至100%）。不同土壤理化性質及不同土壤層間與殘留量均沒有顯著關係。
• 英文摘要： Residues of chlorinated hydrocarbon insectidies and some of their metabolites, including ρ,ρ'-DDT,ρ,ρ'-DDD, ρ,ρ'-DDE, γ-BHC, aldrin, dieldrin, heptachlor and heptachlor epoxide, were examined in thesoils collected from 21 tea-gardens distributed in 15 counties of 6 prefectures in 1977, and from 100locations distributed in 46 counties of 10 prefectures in 1984 in Taiwan. Although the use of these chlorinated hydrocarbon insecticides has been banned for many years,minor amounts of residues in the soils have still been detected. From 1977 to 1984, average residues ofthe chlorinated hydrocarbon insecticides and their metabolites in the soils of tea-gardens decreased from5.64 to 0.06 ppb for γ-BHC, 97 54 to 1.10 ppb for aldrin, 35.91 to 1.00 ppb for ρ,ρ'-DDE, 17.41 to0.28 ppb for dieldrin, and 30.17 to 3.42 ppb for ρ,ρ'-DDT. But the number of positive cases increasedfor all chlorinated hydrocarbon insecticides tested, the residual levels were not significantly differentamong soils with different physiochemical properties or among soil layers. No significant amount of theseinsecticides was found in the processed tea.
