Abstract: | Two typical neutral soils were treated with 10, 200 and 2000 ppm 4-chloro-o-cresol and 5-chloro-3-methylcatechol under field capacity condition, and incubated for 12 weeks at room temperature. The samples were collected after 0, 2, 4, 8 and 12 weeks to study the fate of the compounds by gas chromatography. The two compounds were rapidly degraded and degradation was almost complete (90–96 %) after 4 weeks with a level of 10 ppm. The rate of persistence was similar in the two soils after different periods of incubation. |
