[14C]Aldrin was applied to soils (about 3kg/ha) in outdoor boxes at various locations (Germany, England, and United States), and crops were cultivated (maize, wheat, sugar beets, and potatoes). In the following year, crop rotation experiments were carried out in the same soils without retreatment; in addition, wheat was grown in soils retreated with [14C]aldrin (3.5 kg/ha). After the harvest of both years, the distribution of aldrin and major metabolites (dieldrin; photodieldrin; hydrophilic metabolites including dihydrochlordene dicarboxylic acid; an unidentified nonpolar compound X; and unextractable metabolites) was determined in plants, soils, and leaching water. Two further conversion products, photoaldrin and aldrin-trans-diol, occurred in trace amounts only in a few samples. Metabolic pathways for aldrin under outdoor conditions are presented. The distribution of radioactive residues in soils and plants as well as their quantitative chemical composition are discussed, and comparisons are made between the different experimental sites, the crops, the first and second year, and retreated and nonretreated samples. The quantitative results are compared to those of field trials.
将[14C]艾氏剂以约3千克/公顷的用量施用于不同地点（德国、英国和美国）户外箱中的土壤，然后种植作物（玉米、小麦、甜菜和土豆）。次年，在相同土壤中进行轮作试验，不再重新处理；此外，在以[14C]艾氏剂（3.5千克/公顷）重新处理过的土壤中种植小麦。两年收获后，测定了植物、土壤和淋溶水中艾氏剂及其主要代谢物（狄氏剂、光狄氏剂、包括二氢氯丹二羧酸在内的亲水性代谢物、一种未鉴定的非极性化合物X以及不可提取的代谢物）的分布情况。另外两种转化产物，光艾氏剂和艾氏剂反式二醇，仅在少数样品中以痕量出现。介绍了户外条件下艾氏剂的代谢途径。讨论了土壤和植物中放射性残留的分布及其定量化学组成，并对不同试验地点、作物、第一年和第二年以及重新处理和未重新处理的样品进行了比较。将定量结果与田间试验结果进行了比较。
