Abstract
Microplastics are a kind of emerging pollutants that are very widely distributed in soil and water. Phosphorus in soil and water often exceeds the standard due to phosphorus fertilizer. This paper summarizes the interaction of microplastics on phosphorus in water and soil from the aspects of aging, particle size, and species of microplastics. The results show that phosphorus adsorption of microplastics is related to the particle size and type of microplastics. The larger the particle size of the microplastics, the lower the adsorption capacity of phosphorus. Aging microplastics can improve the adsorption capacity of microplastics. After entering the water and soil environment, they may combine with phosphorus to form complexes, thus changing the migration behavior of phosphorus. Microplastics can be used as the carrier of phosphorus, promoting the migration of phosphorus in the soil and water environment under the action of water flow and wind power, so that the pollution range of phosphorus is expanded. Microplastics may affect the chemical form transformation of phosphorus in the soil and water environment. Due to the different types of microplastics, the adsorption intensity of phosphorus is also different.
