• 中文摘要： 將 Saturn、Machete 及 Tok 以不同量加入含有 1 ppm 之土壤中發現，三種殺草劑在低濃度（Saturn lOμg/g; Tok 10μg/g; Machete 25μg/g）時對土壤中 之產生幾乎全無影響。當土壤中三種殺草劑之濃度較高（Saturn＞25μg/g；Tok＞100μg/g; Machete＞100μg/g）時，土壤中 之產生則遭受抑制。其抑制能力以 Machete＞Saturn＞Tok。 三種殺草劑都可促進土壤中 之產生，此種促進作用在低濃度（Machete 25μg/g；Saturn l0μg/g; Tok l0μg/g）時，即已很顯著。其促進產生 之能力以 Tok＞Saturn＞Machete。　所有經處理之土壤均無可被偵測之 存量，顯然三種農藥加於土壤後都不會促進 的累積。
• 英文摘要： When Saturn, Machete, and Tok were addedto soils which had been pretreated withwas found that the three herbicideswere at relatively low concentrations in soil(Saturn 10μg/g; Tok l0μg/g; Machete 25μg/g),they had almost on effect on the production ofin the soil, while at higher concentra-tions (Saturn＞25μg/g; Tok＞100μg/g; Mache-te＞100μg/g) the production of in thesoil was markedly inhibited. The degree ofinhibition of production in the soil ofthe three herbicides tested was in the followingorder: Machete＞Saturn＞Tok. All three herbicides studied in this experi-ment increased the Accumulation inthe soil even at low concentrations (Machete25μg/g; Saturn l0μg/g; Tok 10μg/g). Thetendency to stimulate production in thesoil for the three herbicides studied was foundto occur in the following order: Tok＞Saturn＞Machete. No detectable amounts of werefound in the soils from any of the treatments.
