Abstract

We conducted an experiment to investigate the effects of ²³²Th on soil enzymes and microbial diversity in soils. Under each treatment, elevated ²³²Th obviously inhibited the activity of soil enzymes such as urease (UR), dehydrogenase (DH), catalase (CAT), phosphatase (PHO) and aryl sulfatase (AS). In each treatment, Proteobacteria was the most dominant flora followed by Actinobacteria and Acidobacteria. Pseudomonas sp. was the dominant strain. This study might provide the preliminary analysis of soil enzymes and microbial diversity in Th contaminated soils.
