The intensive use and wide-ranging application of plastic- and plastic-derived products have resulted in alarming levels of plastic pollution in different environmental compartments worldwide. As a result of various biogeochemical mechanisms, this plastic litter is converted into small, ubiquitous and persistent fragments called microplastics (<5 mm), which are of significant and increasing concern to the scientific community. Microplastics have spread across the globe and now exist in virtually all environmental compartments (the soil, atmosphere, and water). Although these compartments are often considered to be independent environments, in reality, they are very closely linked. Ample research has been done on microplastics, but there are still questions and knowledge gaps regarding the emission, occurrence, distribution, detection, environmental fate and transport of MPs in different environmental compartments. The current article is intended to provide a systematic overview of MP emissions, pollution conditions, sampling and analytical approaches, transport, fates and transformation mechanisms in different environmental compartments. It also identifies research gaps and future research directions and perspectives.
塑料及其衍生产品的大量使用和广泛应用导致了全球不同环境介质中令人震惊的塑料污染水平。由于各种生物地球化学机制的作用，这些塑料垃圾转化为小而普遍存在的持久性碎片，称为微塑料（<5 毫米），这引起了科学界的极大关注。微塑料已经遍布全球，现在几乎存在于所有环境介质（土壤、大气和水）中。尽管这些介质通常被认为是独立的环境，但实际上它们是紧密相连的。已经对微塑料进行了大量研究，但对于 MPs 在不同环境介质中的排放、出现、分布、检测、环境命运和迁移仍然存在问题和知识空白。本文旨在对 MPs 在不同环境介质中的排放、污染状况、采样和分析方法、迁移、命运和转化机制进行系统综述。它还确定了研究差距以及未来的研究方向和前景。
