研究问题

Environmental MPs, however, differ fundamentally from virgin polymers and many conventional post-consumer plastic feedstocks because they are generally heterogeneous in polymer composition and size, environmentally aged, biofouled, dispersed within mineral or organic matrices, and potentially associated with metals, persistent organic contaminants, additives, microorganisms, and degradation products ().;A further challenge is that the available evidence is methodologically heterogeneous.

方法

Bibliometric expansion in biodegradation research has occurred faster than the development of standardized criteria for demonstrating these different stages.;Microbial studies additionally differ in biofilm incubation time, polymer aging, environmental matrix, sequencing or cultivation approach, and whether taxonomic profiles are accompanied by functional measurements.;More specialized recent syntheses have begun to integrate plastisphere ecology with marine biogeochemical cycling and microbial transformation, but the connection between these environmental processes and downstream safety criteria for remediation and resource recovery remains incompletely developed ().

核心结论

Recent global-scale analyses further demonstrate that their occurrence is both widespread and highly heterogeneous. ) compiled 6,464 georeferenced water-sample concentration records from rivers, lakes, and oceans collected between 2014 and 2024 and identified pronounced spatial differences among aquatic systems, together with substantial disparities in monitoring coverage and reporting practices.;Consequently, environmental exposure cannot be interpreted solely from the abundance or polymer identity of pristine particles; MPs acquire new physicochemical and biological properties as they move through interconnected ecosystems.;Plastic surfaces provide persistent substrates for bacteria, archaea, fungi, microalgae, and other microorganisms, producing structured biofilm communities collectively termed the “plastisphere” (). ‖ 结论:This microbiology-informed framework provides a more defensible basis for integrating MP ecology, ecotoxicology, remediation, and circular-resource management.

局限

Likewise, ecotoxicological effects depend on particle properties, exposure conditions, co-contaminants, and environmental stressors, while analytical heterogeneity in sampling, size cut-offs, recovery, polymer identification, and reporting units remains a major barrier to cross-study comparability.

对本项目的价值

★☆☆☆☆ 菌群是可远程部署、成本最低的干预变量,但因果性与个体化响应仍是主要瓶颈。
