Migration and Transformation Characteristics of Niclosamide in a Soil-Plant System.

ABSTRACT: The molluscicide niclosamide is found in most of the wetlands of China. The migration and transformation pathways, and degradation kinetics of niclosamide in the plant-soil system was analyzed by with the use of potting experiment. Experimental results showed that degradation of niclosamide in rhizosphere soil fit the first-order kinetics, and microorganisms played an important role in the degradation of niclosamide. It was found that niclosamide degrades to form a series of aromatic intermediate products both in soil and plants. Niclosamide could be absorbed from soil to plant by the root and then migrate to the stem. At an initial concentration of niclosamide of 2.11 mg·kg^-1 in soil, the maximum residue of niclosamide in Artemisia somai aerial was 2.47 mg·kg^-1
