Abstract: The migration of phenanthrene and factors affecting its migration in soil in presence of LAS are studied through the simulation of soil column. Results show that:① Through 180 days of leaching, when the LAS concentration is 0.5 or 5mg·L-1, the phenanthrene residual rate is less than 10 percent and the residue distributes mainly in surface soil(0-5cm);② When LAS concentration is 0.5mg·L-1, the phenanthrene residual rate in soil is 3-8 times that of LAS concentration being 5mg·L-1;③ The phenanthrene residual rate in soil is 2.5-6 times that of soil that with organic matter removed.It's shown that the LAS concentration has obvious effect for the phenanthrene residual rate in soil and the organic matter in soil has good cap ability in keeping phenanthrene.
