| 摘要: |
| 微塑料是现代化社会经济活动的产物，于近海岸富集会导致海水、地下水与近岸土壤环境的污染。微塑料具有多样化的物理化学性质，运移机制复杂。伴随人类活动加剧与水动力条件变化，微塑料在滨海地区广泛迁移并形成差异分布。微塑料能够释放自身有毒物质，吸附重金属离子与有机污染物，使海岸带区域水环境污染加剧，严重危害滨海地区动植物的生长发育，威胁人类健康及滨海生态安全。因此，探究微塑料在滨海地下水含水层中的转运机制，对于分析其对生态环境的潜在危害、采取有效手段应对微塑料污染具有重要意义。 |

| Abstract: |
| The occurrence of microplastics is usually combined with the products of modern social and economic activities, which can cause pollution of seawater, groundwater and nearshore soil when they are enriched in the coast zone. Due to the complicated migration mechanisms and diversified physical and chemical properties, microplastics are widely distributed in coastal areas and show differentiation under the intensification of human activities and the change of hydrodynamic conditions. Microplastics can release toxic substances, adsorb heavy metal ions and organic pollutants, which induce the pollution of coastal water environment. It seriously endangers the growth and development of plants and animals in coastal areas and threatens human health and coastal ecological security. Therefore, exploring the transport mechanism of microplastics in coastal groundwater aquifers is of great significance to examining the potential harm of microplastics in the ecological environment and to dealing with microplastic pollution with effective means. |
