Fe3+ alleviates the toxic effect of CuSO4 on Microcystis aeruginosa
The objectives of this study were 1) to illustrate the growth, photosynthesis activity, and antioxidant enzyme ability of M. aeruginosa under iron effect of CuSO4 application, 2) to determine the variation in metabolic activity of M. aeruginosa and 3) to clarify the mechanism of iron-copper-nitrogen on microcystin. This study will provide a theoretical basis for the potential impact of CuSO4 as an algaecide and iron elements in water on algal blooms, offering a deeply understanding of the relationship among iron-copper-microcystin.
