Impact of Microplastics on Microbial Communities and Arsenic Speciation Transformation at Arsenic-contaminated Soil
Microplastics have been widely found in natural environment and may pose potential exposure risks to ecosystems and human health. Most of researches focuses on the fate of microplastics in aquatic environment,while a few studies were related to behaviors of microplastics in soil. The present study was conducted to examine the impacts of microplastics(polyethylene(PE) and polylactic acid(PLA)) on microbial communities and arsenic transformation in arsenic-contaminated soils. Results indicate that both types of microplastics enhanced the abundance of microbial species in the soil. Compared to control group,the proportion of bioavailable arsenic species were greater in the soil + PLA groups. Both types of microplastics would increase the arsenate gene copies in soil at 6 and 12 d,promoting the reduction of bioavailable pentavalent arsenic to trivalent arsenic. The present study found that microplastics could affect the proportions of bioavailable arsenic in soil,providing data for subsequent research.
