Abstract

The "Trojan horse effect" of microplastics for organic and inorganic contaminants is an interesting topic. So far, the scientific community has focused on microplastics strictly as contaminants, but their role as vectors is still undefined. Adsorption of pollutants follows the Freundlich model by physisorption mechanism. Furthermore, ages and types of microplastics influence the adsorption of pollutants onto microplastics. Moreover, natural particles, like algae particles, present in the environment can interfere in the adsorption mechanisms. Due to their chemical composition of mainly O and N, it has been suggested that natural particles have a stronger adsorption affinity for some pollutants. Furthermore, microplastic's role as vector of pollutants into organisms is controversial. In fact, it has been suggested that the release is species-specific. In T. japonicus, accumulation of Hg loaded onto microplastics increased by 2.5 times, whereas a reduction of bioavailability of Hg was observed in R. lens.

微塑料的特洛伊木马效应:关于它们在几种基质中作为有机和无机化合物载体的作用的综述
& lt; abstract>微塑料对有机和无机污染物的“特洛伊木马效应”是一个有趣的话题。到目前为止,科学界一直将微塑料严格地视为污染物,但它们作为载体的作用仍未明确。污染物的吸附遵循Freundlich模型的物理吸附机理。此外,微塑料的年龄和类型影响微塑料对污染物的吸附。此外,环境中存在的天然颗粒,如藻类颗粒,会干扰吸附机制。由于天然颗粒的化学成分主要是O和N,因此有人认为天然颗粒对某些污染物具有更强的吸附亲和力。此外,微塑料作为污染物进入生物体的载体的作用是有争议的。事实上,有人认为这种释放是物种特异性的。在& lt; italic> T。在jjaponicus </斜体>中,汞在微塑料上的积累量增加了2.5倍,而Hg的生物利用度则降低了。lens< / italic>灵活;/ p>& lt; / abstract>
