Abstract

Nanomaterials such as single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) may repeatedly enter the soil environment with unknown adverse consequences. To provide the information on the effects of repeated exposure of CNTs, we determined the response of soil enzyme activity and soil basal respiration (SBR) through a two-week incubation of farmland soil repeatedly treated with different concentrations of CNTs (100, 200, 500 mg kg−1 for SWCNTs and 100, 500, 1000 mg Kg−1 for MWCNTs). The activities of catalase, alkaline phosphatase, and invertase and SBR were measured after one- and two-time treatments. The repeated contamination of SWCNTs and MWCNTs repressed the ..
