The effect of microplastics (MPs) on the M. roraima response to M. aeruginosa exposure was studied. The effect of MPs on cyanobacteria was also tested. The adsorption of microplastics to the M. roraima roots was unchanged in M. aeruginosa co-culture compared to the monoculture. The cyanobacteria affected the growth and physiology of M. roraima than monoculture. Under the co-existence condition, M. aeruginosa growth was reduced at lower MP concentration and increased at higher concentrations. The oxidative stress increased at higher MP concentrations. Nanoplastic exposure experiments revealed that nano-plastics also have impacts on M. roraima and M. aeruginosa growth and physiology. Fieldwork found that almost all the freshwater resources we tested were contaminated with microplastics.

研究了微塑料对M. roraima对M.研究了铜绿假单胞菌暴露。还测试了MP对蓝藻的影响。研究了M.罗赖马根在M.铜绿假单胞菌共培养与单一培养相比。蓝藻对M.罗赖马比单一文化。在共存条件下，M.铜绿假单胞菌的生长在较低的MP浓度下减少，在较高的浓度下增加。氧化应激增加，在较高的MP浓度。纳米塑料暴露实验表明，纳米塑料也对M。roraima和M.铜绿假单胞菌生长和生理。实地调查发现，我们测试的几乎所有淡水资源都受到微塑料污染。
