Multiple Endpoints of Polyethylene Microplastics Toxicity in Vascular Plants of Freshwater Ecosystems: A Study Involving Salvinia Auriculata (Salviniaceae)

Review of green technologies for the removal of microplastics from diverse environmental sources

“…Further investigation was carried out by Gomes et al. (2022) and analyzed dehydrated filaments and moreover, they observed possible deformations when plants are subjected to pollutants. Additional observations were analyzed in the sticking of PE–MPs on the adaxial and abaxial surface, decrease in chlorophyll content, rupture in cell membrane, instability in redox reactions (indicated by the activity of reduced catalase and superoxide dismutase), raise in the synthesis of reactive oxygen & nitrogen species and malondialdehyde and concluded the ability of trapping PE–MPs on S. auriculata and further emphasized on over dumping of these pollutants creates negative impacts on freshwater ecosystems.…”

“…Gomes et al (2022) analyzed the multiple endpoints of toxicity of PE-MPs in vascular plants of freshwater ecosystems and estimated the plausible effects of release of Salvinia auriculata to PE-MPs for 4 weeks using various biomarkers whose findings demonstrated that S. auriculata, when subjected to PE-MPs alter the generations in plants, decrease the scattering of the individuals in the experiment, lessen the thickness of epidermis and increases the length of vein and vascular bundle of S. auriculata whose ultrastructure when subjected to MPs destroyed the cells of epidermis and trichomes on the adaxial and abaxial surface, necrosis and chlorosis on the leaves. Further investigation was carried out by Gomes et al (2022) and analyzed dehydrated filaments and moreover, they observed possible deformations when plants are subjected to pollutants.…”
