• 摘要：本文利用(14)C—林丹研究了γ-六六六在不同土壤中的吸附性及其在土壤和小麦中残留量的关系。试验表明,γ-六六六在土壤中的吸附率与土壤中的有机质含量、可萃取铝含量和酸性等均有密切关系。同时,环境温度对吸附率也有一定影响。通过(14)C—林丹在不同土壤和小麦植株中残留量的测定,证明土壤中γ-六六六的吸附率、小麦对土壤中r-六六六的吸收率以及γ-六六六在土壤和小麦中的残留量相互之间均有明显的相关性。为此,本研究不仅摸清了某些影响土壤吸附γ-六六六和小麦吸收γ-六六六的理化因子,同时,对用土壤某些理化性质的测定值来预测栽培试验时土壤和小麦中六六六的残留水平提供了一个途径。

• Abstract：14C-Lindane was used to study adsorbability of Lindane (γ-BHC) in different types of soil, and its correlation with residual Lindane in wheat and in respective soils. Experimental results show that adsorption of γ-BHC in soils has a close relation to organic matter contents and extractable aluminum, as well as pH of the soil. Temperature also has its effect. Data analysis also shows that there is a significant interrelation among adsorption of γ-BHC in soil, ratio of γ-BHC adsorbed by wheat from soil and residual γ-BHC in soil and the wheat itself. For a specific soil, if its physical and chemical properties are known, adsorption of γ-BHC can be predicted, and thus can be used to estimate the residual level of γ-BHC in the soil and in wheat grown therein.
