生物降解塑料自然和人工强化环境中碳代谢研究进展与展望OA
Research progress and outlook on carbon metabolism of biodegradable plastics in natural and engineered environments
生物降解塑料作为传统塑料的重要替代品,因其环境友好特性而被逐渐推广用于食品包装材料和农用地膜等.近年来,生物降解塑料制品废弃后对环境造成的污染风险受到广泛关注.然而,其在不同接收环境中的碳代谢行为及微塑料污染仍缺乏系统的梳理.本文综述了生物降解塑料碳代谢机制中的同化和矿化作用最新进展,比较了不同接收环境中其碳代谢的差异,对比分析了最新可降解微塑料的检测技术.未来的研究主要面临生物可降解塑料全生命周期的跨介质的碳代谢定量分析、生物降解微塑料高通量检测等挑战.
As an important alternative to conventional plastics,biodegradable plastics have been progressively adopted for applications such as food packaging materials and agricultural mulch films due to their environmentally friendly properties.In recent years,the environmental pollution risks posed by discarded biodegradable plastic products have garnered widespread attention.However,systematic investigations into their carbon metabolism behavior and microplastic pollution across different receiving environments remain scarce.This review summarizes recent advances in assimilation and mineralization mechanisms within the carbon metabolism of biodegradable plastics,compares differences in their carbon metabolism across various receiving environments,and analyzes the latest detection technologies for degradable micro-and nano-plastics.Future research faces key challenges including quantitative analysis of cross-medium carbon metabolism throughout the entire life cycle of biodegradable plastics and high-throughput detection of biodegradable microplastics.
