微塑料对微藻的毒性效应研究进展

Toxicity research progress of microplastics on microalgae

  • 摘要: 微塑料(MPs)污染已经成为全球的持久性污染问题,引起了世界范围内的广泛关注。目前的研究表明,微塑料对水环境中的初级生产者微藻具有一定的毒害作用,同时,微塑料与其他污染物结合还可能产生更为严重的联合毒性效应,进而影响水体中食物链的稳定性,并对生态系统的健康带来潜在的风险。因此,开展微塑料对微藻毒性效应的研究十分必要。本文介绍了已公开发表的相关研究及成果,总结了微塑料对微藻的机械损伤、遮蔽效应、氧化损伤、吸附和团聚等致毒机理,并对未来微塑料对微藻毒性的研究方向做了简要分析与展望。

     

    Abstract: Microplastics (MPs) pollution has become a global environmental problem.A few papers reported that MPs could have toxic effect on microalgae.Moreover, due to their strong binding ability, MPs may induce joint toxicity with other contaminants.As microalgae are the most primary producers in water system, the toxic effect is likely to influence the stability of food chains in water and further bring potential risks to human beings.The present paper reviewed the current research achievements and possible toxicity mechanisms, including physical damage, shielding effect, oxidative stress, adsorption and hetero-aggregation.In addition, future research directions were also proposed and discussed.
