Abstract:In order to investigate the effects of macroplastics (>5mm) and microplastics on the transformation of heavy metal speciation in soil, macroplastics and microplastics with different doses (0.1%, 1%, and 7%) were mixed in cadmium (Cd) contaminated farmland soil for incubation to evaluate their impacts on soil properties, bioavailability and chemical speciation of Cd. Results showed that after 120 days of incubation, compared with the control treatment, macroplastics and 0.1% microplastics had less impact on soil pH, while 1% and 7% microplastics addition reduced soil pH by 0.13 and 0.36 units, respectively. Besides, the content of soil dissolved organic carbon (DOC) was increased by 6.45%~14.38% in the presence of macroplastics, but decreased by 17.10% in the presence of 7% microplastics. In addition, macroplastics showed little effect on Cd bioavailability, while microplastics increased the exchangeable fractionation and bioavailability of Cd in soil, and the effect was positively correlated with the dose. Among them, 7% microplastics increased the proportion of the exchangeable and carbonate-bound Cd by 12.77%, and the proportion of the Diethylene triamine pentaacetate acid (DTPA) extractable Cd was increased by 7.91%. The results of this study will provide a theoretical basis for preventing and controlling the combined pollution of plastic and heavy metals in agricultural soils.
