Microplastics [MPs], now a ubiquitous pollutant in the oceans, pose a serious potential threat to marine ecology and has justifiably encouraged focused biological and ecological research attention. But, their generation, fate, fragmentation and their propensity to sorb/release persistent organic pollutants (POPs) are determined by the characteristics of the polymers that constitutes them. Yet, physico-chemical characteristics of the polymers making up the MPs have not received detailed attention in published work. This review assesses the relevance of selected characteristics of plastics that composes the microplastics, to their role as a pollutant with potentially serious ecological impacts. Fragmentation leading to secondary microplastics is also discussed underlining the likelihood of a surface-ablation mechanism that can lead to preferential formation of smaller sized MPs.
微塑料[MPs]如今是海洋中一种普遍存在的污染物，对海洋生态构成严重潜在威胁，理所当然地引发了生物学和生态学领域的重点研究关注。但是，它们的产生、归宿、破碎以及吸附/释放持久性有机污染物（POPs）的倾向是由构成它们的聚合物特性所决定的。然而，构成微塑料的聚合物的物理化学特性在已发表的研究中尚未得到详细关注。本综述评估了构成微塑料的塑料的选定特性与其作为具有潜在严重生态影响的污染物的作用之间的相关性。还讨论了导致次生微塑料的破碎过程，强调了表面烧蚀机制导致优先形成较小尺寸微塑料的可能性。
