Acute Toxicity of Quizalofop-p-ethyl on Aquatic Plant
Abstract: Microcystis viridis is the longest harmful cyanobacteria in Chaohu cyanobacteria of dominant species in central. It produce more toxicity than Microcystis aeruginosa. However，studies of Microcystis viridis is less. With the intensification of inland water eutrophication caused by harmful algal blooms has become a frequent occurrence of environmental issues of common concern at home and abroad, including microcystis blooms is the most serious category in freshwater bodies, since these water bloom widespread and most toxigenic greater dangers, which poses a potential environmental risk of a large number of residues in the environment. Green algae as a biological model, the degree of oxidative damage by measuring algal cells inside and outside the algal cells microcystin LR content Quizalofop green Microcystis growth inhibition effect Quizalofop protein content, the study herbicide quizalofop ecotoxicity of cyanobacteria. The results show: 0.5 mg / L of Quizalofop can stimulate the growth of green Microcystis cells, while green microcystin at prolonged exposure to high concentrations Quizalofop its growth was inhibited. Probed into the future research directions, aimed to provide valuable reference for the ecological risk assessment of the antibiotics.
