[Distribution and Sources of Microplastics in Farmland Soil Along the Fenhe River].

This study investigated the distribution and sources of microplastics smaller than 1 mm in farmland soil along the Fenhe River. Microplastics in soil samples were separated and extracted using the traditional density centrifugation method. The quantity and type of microplastics were examined with a stereomicroscope. The micro-morphology of plastic particles were observed with a scanning electron microscope-energy dispersive spectrometer. The chemical composition was determined using Fourier transform infrared spectroscopy. The results indicate that the average abundance of microplastics in farmland soil along the Fenhe River is 290.5 n ·kg
