Microplastics have been identified in all living forms including human beings, the present need is to restrain its spread and devise measures to remediate microplastics from polluted ecosystems. In this regard, the present review emphasizes on the occurrence, sources detection and toxic effects of microplastics in various ecosystems. The removal of microplastics is prevalent by various physico-chemical and biological methods, although the removal efficiency by biological methods is low. It has been noted that the degradation of plastics by insect gut larvae is a well-known aspect, however, the underlying mechanism has not been completely identified. Studies conducted have shown the magnificent contribution of gut microbiota, which have been isolated and exploited for microplastic remediation. This review also focuses on this avenue, as it highlights the contribution of insect gut microbiota in microplastic degradation along with challenges faced and future prospects in this area.
在包括人类在内的所有生物体内都已发现微塑料，当前的需求是抑制其传播，并制定措施从受污染的生态系统中修复微塑料。在这方面，本综述着重探讨了微塑料在各种生态系统中的存在情况、来源检测及毒性影响。通过各种物理化学和生物方法去除微塑料的情况很普遍，不过生物方法的去除效率较低。人们已经注意到昆虫肠道幼虫对塑料的降解是一个广为人知的现象，然而其潜在机制尚未完全明确。已开展的研究表明肠道微生物群发挥了巨大作用，它们已被分离出来并用于微塑料修复。本综述也聚焦于这一途径，因为它突出了昆虫肠道微生物群在微塑料降解中的作用，以及该领域面临的挑战和未来前景。
