Microcystis aeruginosa is a dominant cyanobacterium commonly found in Chinese freshwater ecosystems during phytoplankton blooms, and copper sulfate is one of the most frequently used algicides for controlling the nuisance blooms. In this study, we examined the effects of varied water chemistry (dissolved organic matter, pH, and hardness) on copper (Cu) toxicity to M. aeruginosa, as well as the Cu short-term uptake kinetics, using (67)Cu as a radioactive tracer. Elevated dissolved organic matter… CONTINUE READING
