Plastic trash dumped into water bodies degrade over time into small fragments. These plastic fragments, which come under the category of micro-plastics (MPs), are generally 0.05-5 mm in size, and due to their small size they are frequently consumed by aquatic organisms. As a result, widespread MPs infiltration is a global concern for the aquatic environment, posing a threat to existing life forms. MPs easily bind to other toxic chemicals or metals, acting as vector for such toxic substances and introducing them into life forms. Polyethylene, polypropylene, polystyrene, and other polymers are emerging pollutants that are detrimental to all types of organisms. The main route for MPs into the aquatic ecosystems is through the flushing of urban wastewater. The current paper investigates the origin, environmental fate, and toxicity of MPs, shedding light on their sustainable remediation.
倾倒到水体中的塑料垃圾会随着时间的推移降解成小碎片。这些塑料碎片属于微塑料（MPs）类别，通常尺寸为0.05 - 5毫米，由于其尺寸小，它们经常被水生生物消耗。因此，微塑料的广泛渗透是全球对水生环境的关注焦点，对现存生命形式构成威胁。微塑料很容易与其他有毒化学物质或金属结合，充当这些有毒物质的载体并将它们引入生命形式。聚乙烯、聚丙烯、聚苯乙烯和其他聚合物是对所有类型生物都有害的新兴污染物。微塑料进入水生生态系统的主要途径是通过城市污水的排放。本文研究了微塑料的来源、环境归宿和毒性，为其可持续修复提供了思路。
