The behavior of linear alkylbenzenesulfonate (LAS) in soils (i.e., degradation, percolation, and sorption) was investigated in field and laboratory tests. For this purpose sorption studies were carried out using Freundlich's method in order to obtain sorption constants. A prediction of sorption constants in characterized soils was possible using multiple regression and correlation methods. Degradation under laboratory conditions can faithfully be used for the interpretation of degradation times under field conditions. In laboratory tests LAS has reacted immobilely as in field tests. The uptake of LAS in plants is very high; however, it is slowly metabolized.
通过田间和实验室试验研究了直链烷基苯磺酸盐(LAS)在土壤中的行为(即降解、渗滤和吸附)。为此,采用弗罗因德利希方法进行吸附研究以获得吸附常数。利用多元回归和相关方法可以预测特定土壤中的吸附常数。实验室条件下的降解可如实用于解释田间条件下的降解时间。在实验室试验中,LAS的反应与田间试验一样不活跃。LAS在植物中的吸收量很高;然而,它的代谢缓慢。
