微塑料对植物的毒性效应研究进展

Research Progress in Toxic Effects of Microplastics on Plants

塑料是人类生产生活中的必需品,但由于管制不当,废弃塑料在环境中大量存在,其风化破碎形成的塑料微粒已经成为水生生态系统中的重要污染物,并随着水流遍布世界各地。微塑料本身及其负载的毒性会对水中的植物带来严重威胁。综述了微塑料对高等植物和微藻的生理功能的影响,探讨了微塑料和环境中其他污染物结合产生的复合毒性效应,总结了造成这些负面效应的原因。

Plastic is a necessity in human production and life. However, due to improper control, a large number of waste plastics exist in the environment. Plastic particles formed by weathering and crushing have become important pollutants in aquatic ecosystems, and they are spreading all over the world with the flow of water. The toxicity of microplastics itself and its load will pose a serious threat to plants in water. In this paper, the effect of microplastics on the physiological functions of higher plants and microalgae was reviewed,the combined toxic effect of microplastics and other pollutants in the environment was discussed, and the causes of these negative effects were summarized.
