摘要

塑料微粒(议员;<5毫米)和纳米塑料(NP;现在在自然界中无处不在，因为它们已经通过直接排放、高地流域径流和其他陆地环境释放到内陆水域、湖泊、河流和海水中。为了了解过去十年中MP和NP的聚集情况，进行了调查和分析工作。土壤和水环境中的MP和NP颗粒与其他天然和工程纳米颗粒相互作用，进而形成聚集体。根据pH、离子类型、离子价、盐浓度、塑料颗粒的形状和大小以及MP的聚合物类型，这些塑料颗粒可以形成同质聚集体和/或异质聚集体。由于塑料聚合物类型的不同，MP聚集的差异尚未得到很好的证明。本文研究了不同聚合条件下聚合物类型对MP和NP粒子聚集的影响。

Interaction, Adhesion and Aggregation of Microplastic/Nanoplastic Particles: Effects of Plastic Polymer Type

Microplastics (MP; <5 mm) and nanoplastics (NP; <1000 nm) are now ubiquitous in nature as they have been released into inland water, lakes, rivers, and marine water through direct discharge, runoff from upland watersheds, and other terrestrial environments. To understand the aggregation of MP and NP in the last decade, surveys and analytical efforts were undertaken. The MP and NP particles in the soil and water environments interact with other natural and engineered nanoparticles, which in turn form aggregates. These plastic particles could form homoaggregates and/or heteroaggregates depending on pH, ionic type, ionic valence, salt concentration, shape and size of the plastic particles, and the polymer type of MP. Differences in MP aggregation due to differences in plastic polymer type are not yet well documented. This review is conducted to investigate the effect of polymer type on the aggregation of MP and NP particles in the presence of various aggregation conditions.

期刊介绍： Asia, as a whole region, faces severe stress on water availability, primarily due to high population density. Many regions of the continent face severe problems of water pollution on local as well as regional scale and these have to be tackled with a pan-Asian approach. However, the available literature on the subject is generally based on research done in Europe and North America. Therefore, there is an urgent and strong need for an Asian journal with its focus on the region and wherein the region specific problems are addressed in an intelligent manner. In Asia, besides water, there are several other issues related to environment, such as; global warming and its impact; intense land/use and shifting pattern of agriculture; issues related to fertilizer applications and pesticide residues in soil and water; and solid and liquid waste management particularly in industrial and urban areas. Asia is also a region with intense mining activities whereby serious environmental problems related to land/use, loss of top soil, water pollution and acid mine drainage are faced by various communities. Essentially, Asians are confronted with environmental problems on many fronts. Many pressing issues in the region interlink various aspects of environmental problems faced by population in this densely habited region in the world. Pollution is one such serious issue for many countries since there are many transnational water bodies that spread the pollutants across the entire region. Water, environment and pollution together constitute a three axial problem that all concerned people in the region would like to focus on.
