Toxicity of polystyrene microplastics in freshwater algae Scenedesmus obliquus: Effects of particle size and surface charge

Polystyrene nanoplastics alter the ecotoxicological effects of diclofenac on freshwater microalgae Scenedesmus obliquus

“…Dichlorofluorescein diacetate (DCFH-DA) (fluorescent dye), which can pass through the algal cell membrane composed of a lipid bilayer, was used to evaluate the total ROS generation. 10 The detailed procedure for total ROS assessment is provided in the ESI† (Methods section).…”

“…9 A recent report revealed that PS-MPs (between 1 and 12 mm) reduced the growth rates, as well as chlorophyll and esterase activities, and increased the production of oxygen species and related antioxidant enzyme activity in S. obliquus in a concentration dependent manner. 10 NPs frequently coexist in aquatic environments with other contaminants, such as heavy metals, pesticides, pharmaceuticals, and other nanoparticles. 11 Among them, pharmaceuticals from diverse categories are used to treat and maintain the health of both humans and animals.…”

Ecotoxicological significance of bio-corona formation on micro/nanoplastics in aquatic organisms

“…[34][35][36][37] The diverse adverse effects such as oxidative damage, retorted growth, organelle damage, early mortality, decreased food uptake, inammation, immune malfunctions and aberrant behavior are the major detrimental effects of M/NPs on the aquatic biota. [38][39][40][41][42][43]…”
