Residue disappearance and leaching of 14C-allylalcohol from different soils were studied in laboratory experiments. Additionally, the uptake of residues by lettuce and carrots was investigated in the greenhouse. In laboratory experiments, residue disappearance and leaching from soils was correlated negatively to the organic matter content. In greenhouse experiments with a sandy loam soil at an application rate normally used in practice, an average of 12.5% of the applied radioactivity was recovered after an eight day interval between application and sowing. Furthermore, an average of 8% (sum in soil and plants) of the applied radioactivity was recovered after lettuce or carrot growing. Uptake of residues was higher by carrots than by lettuce, and higher by lettuce roots than by lettuce tops. No bioaccumulation was observed. The residues in soils and plants were, to a high percent-age, unextractable and, to a smaller extent, fully water-soluble products. Unchanged allylalcohol could not be detected by the analytical methods used.
在实验室实验中研究了不同土壤中14C-烯丙醇的残留消失和淋溶情况。此外，还在温室中研究了生菜和胡萝卜对残留物的吸收情况。在实验室实验中，土壤中残留物的消失和淋溶与有机质含量呈负相关。在温室实验中，使用砂壤土，按照实际常用的施用量，在施药和播种之间间隔八天后，平均回收了12.5%的施用量放射性物质。此外，在生菜或胡萝卜生长后，平均回收了8%（土壤和植物中的总和）的施用量放射性物质。胡萝卜对残留物的吸收高于生菜，生菜根部对残留物的吸收高于生菜顶部。未观察到生物累积现象。土壤和植物中的残留物大部分不可提取，只有一小部分是完全水溶性产物。使用的分析方法未检测到未变化的烯丙醇。
