Summary

Researchers investigated how fluorescent nanoplastics modify the toxic effects of titanium dioxide nanoparticles on the freshwater algae Scenedesmus obliquus. They found that when nanoplastics were combined with titanium dioxide, oxidative stress markers, lipid damage, and antioxidant enzyme activity all increased significantly beyond individual exposures. The study demonstrates that nanoplastics can enhance the toxicity of other environmental contaminants in freshwater organisms.

Study Type Environmental

The increased usage of titanium dioxide nanoparticles (nTiO) in consumer products has led to their prevalence in freshwater systems. Nanoplastics, a secondary pollutant, can significantly influence the toxic effects of nTiO in freshwater organisms. The present study investigates the role of fluorescent nanoplastics (FNPs) in modifying the harmful effects of P25 nTiO in freshwater algae Scenedesmus obliquus. Three different concentrations of nTiO, 0.025, 0.25, and 2.5 mg/L, were mixed with 1 mg/L of the FNPs to perform the mixture toxicity experiments. The presence of the FNPs in the mixture increased the toxicity of nTiO significantly. A significant increment in the oxidative stress parameters like total ROS, superoxide (O), and hydroxyl radical generation was observed for the mixture of nTiO with the FNPs in comparison with their individual counterparts. The lipid peroxidation, and the antioxidant enzyme activities in the algal cells correlated well with the reactive species generation results. The treatments with the binary mixture resulted in notable decrease in the esterase activity in the algal cells. The mixture toxicity results were further validated with Abbott's independent action model. Additionally, optical microscopic analysis and FTIR analysis were performed to study the morphological and surface chemical changes in the algae. This study demonstrated that the FNPs played a key role in enhancing the toxicity of nTiO in freshwater algae.
