太原市景观水体微塑料赋存特征及风险评估
Pollution characteristics and risk assessment of microplastics in urban landscape waters of Taiyuan City
摘要
Abstract
To investigate the distribution characteristics and ecological risks of microplastics in landscape waters in Taiyuan City,surface water samples were collected from six park waters during the wet season(August)and dry season(November).The abundance,morphology,and polymer composition of microplastics were analyzed using a stereomicroscope and a Fourier transform infrared spectrometer(FTIR),and correlation analysis and ecological risk assessment were performed based on certain water quality parameters.The microplastic abundance in the dry season((17.79±8.41)items/L)was found to be higher than that in the wet season((7.75±4.30)items/L).The landscape water body in Binhe Country Park,located near the effluent outlet of a wastewater treatment plant,exhibited significantly higher microplastic abundance than other areas.The morphological characteristics were dominated by fibrous(79.35%～88.62%),blue(60.69%～78.64%),and small(0.02～2 mm,84.80%～91.10%)particles.The primary polymer components were rayon(RY),polypropylene(PP),and polyethylene terephthalate(PET),indicating that domestic sewage and textile fiber migration were the primary sources of pollution.The distribution of microplastics was jointly influenced by hydrological conditions and nitrogen and phosphorus concentrations.The abundance in the wet season was negatively correlated with water temperature(p<0.05),and significantly positively correlated with ammonia nitrogen(NH4+-N),nitrate nitrogen(NO3--N),total phosphorus(TP),etc.(p<0.01)in the dry season.The ecological risks showed significant seasonal and spatial variation.During the dry season,the sampling sites at Forest Park,Longtan Park,and Jinci Park showed markedly elevated potential ecological risk index(PERI)values owing to the accumulation of high-toxicity polymers(polyacrylonitrile and polyurethane),and the risk level could reach Ⅳ-Ⅴ.This study may provide valuable insights for the pollution status and risk assessment of microplastics in urban landscape waters in northern cities.关键词
