Effect of Polyethylene (LDPE) Microplastic on Remediation of Cadmium Contaminated Soil by <i>Solanum nigrum</i> L.

Solanum nigrum L. has a delightful prospect as hyperaccumulation plant for cadmium pollution remediation, and microplastic is new type of that received wide attention. In this study, the effects polyethylene microplastics (LDPE) (0.135, 0.27, 0.81 1.35 mg·kg-1) (20 on growth indexes soil physical chemical properties were investigated in 17-day microcosm experiment. The results showed single LDPE contamination trend low concentration promotion medium-high inhibited index physicochemical index, Cd was more stressful to plants than contamination, while could reduce effect promote uptake nutrients. These findings suggest high concentrations can inhibit alone or combination with Cd, rather reducing toxicity Cd.
