从源头到终端:食品微塑料污染的"渗透-响应"与全链条治理OA

As a ubiquitous pollutant,microplastics have entered the global food supply chain through reverse biomagnification and infiltrate the human body via dietary intake,traversing multiple biological barriers and accumulating in key organs.Toxicological and epidemiological evidence reveals strong associations between microplastic exposure and multisystem health risks,including neurodegenerative diseases,metabolic syndrome,cardiovascular disorders,and immune dysfunction.Confronted with this systemic threat,this study constructs a whole-chain governance paradigm spanning from source to endpoint,and proposes systematic policy recommendations across six dimensions:strengthening top-level design,advancing material innovation,improving recycling systems,establishing a national monitoring network,implementing precise risk interventions,and deepening global cooperation.The aim is to provide a theoretical foundation and actionable roadmap for effectively curbing microplastic contamination and safeguarding public health.
