Distribution characteristics of microplastics in typical farmland in Pudong new Area
AI summary Read the abstract
Researchers found microplastic pollution in all three vegetable farming sites studied in Shanghai's Pudong New Area, with an average abundance of 76.2 particles per kilogram of soil, primarily fibers and film fragments linked to the use of agricultural mulching films.
Microplastics are emerging pollutants in the land environment in recent years, which have specific effects on the environment and health, and have become a research hotspot worldwide. To study the pollution status of microplastics in farmland, three vegetable planting bases in Pudong New Area (Shanghai, China) were selected as sampling sites, and the abundance, composition, and characteristics of microplastics in typical farmland were studied. The average abundance of microplastics in the study area was (76.2±12.3) n·kg-1. Microplastics could be divided into four types: fiber (43.61%), thin-film (28.89%), fragment (22.41%), and foam (5.09%). The proportion of microplastics with a particle size of 0-0.5mm (64.9%) was higher than microplastics with a larger particle size. The materials of the fragment, thin-film, fiber, and foam are mainly polyethylene (PE), polypropylene (PP), low-density polyethylene (LDPE), and polyvinyl chloride (PVC), respectively, according to the infrared spectrum. The results showed a certain degree of microplastic pollution in the farmland of Pudong New Area, which was mainly related to the use of mulching film and the planting time of the farmland.

AI summary Read the abstract
Researchers analyzed microplastic distribution in agricultural soils in Guyuan City, China, finding concentrations ranging from 186 to 1,286 particles per kg, with greenhouse farming soils containing 35–229% more microplastics than open fields and PE and PP being the dominant polymer types. The findings raise concern for food chain contamination and demonstrate that plastic mulch film use in facility agriculture significantly increases soil microplastic accumulation.
