摘　　要：用^(14)C标记化合物研究了甲苯在上壤中的吸附、迁移及残留等行为。研究结果表明:甲苯在所试各种土壤中的吸附率均不高、吸附规律符合弗朗德里胥等温方程。甲苯在土壤中易迁移,在土壤中残留半减期较长。The adsorption,migration and persistence of toluene in soils were studied using ^(14)C labeled compound. The results show that the adsorption efficiencies of toluene in various soils are net high Toluene is liable to transport in soils, but the persistence half-life of toluene in soil is rather long.
