城市水生态环境中微塑料污染的来源与风险

Sources and risks of microplastic pollution in urban aquatic ecological environment

阐述了陆域水体环境微塑料污染的研究现状,探讨了污水厂尾水排放、排水系统溢流等微塑料污染来源,概括了微塑料所能构成的生态风险。分析认为:城市水生态环境是陆域环境微塑料的主要输出地,明确其微塑料污染的来源与风险是实现微塑料污染有效管控的关键。

The Research Status of microplastic pollution in terrestrial water environment was described.The microplastic pollution sources such as tail water from wastewater treatment plant(WWTP)and overflow of drainage systems were discussed.Then the ecological risks caused by microplastics were summarized.Analysis shows that urban aquatic ecological environment is the main source of microplastics in terrestrial environment.The key to achieve the effective control of microplastic pollution is identifying the source and risk of microplastic pollution in urban water ecological environment.
