Identifying the sources, migration and risks of microplastics in soil ecosystem along urban-rural landscape
Original title: Identifying the sources, migration and risks of microplastics in soil ecosystem along urban-rural landscape
Summary
This Chinese-language review systematically examined the sources, migration pathways, and ecological and health risks of microplastics in soils across urban and rural landscapes. The authors call for better understanding of microplastic material flows and fate in agricultural and residential soils to protect both soil ecosystems and human health.
土壤微塑料污染的持久性、复杂性及其对土壤生态系统的影响受到越来越广泛的关注，但对其来源、迁移过程等仍有许多问题尚未理清。从复合生态系统的角度，通过对城乡景观中土壤微塑料的来源、迁移过程及其风险等相关研究进展进行了系统梳理，分析了城乡不同景观中土壤微塑料的主要来源和特点，讨论了土壤微塑料在城乡景观中的迁移特征及其驱动力，探讨了土壤微塑料在城乡景观中的生态和健康风险。今后需进一步明确城乡景观中土壤微塑料污染的物质流过程与环境归趋特征，加强微塑料对土壤生态系统的作用过程及生态系统服务影响的研究，揭示土壤微塑料对人类健康的直接或间接影响，建立城乡复合生态系统土壤微塑料污染预测模型，以维护土壤生态安全与人居环境健康。
