Proposed mechanistic scheme for paraquat toxicity (1 mg L−1) in Microcystis aeruginosa and Chlorella sp. The change of photosynthetic processes (Chl a fluorescence, rETRmax) and cell-membrane integrity (SYTRO green positive) in 24 h are defined as acute responses. The variation of oxidative stress (SOD, CAT, MDA, ROS), cell-membrane integrity (SYTRO green positive), and growth (OD680) at 96 h are defined as chronic responses. Significant increased endpoints, significantly decreased endpoints, and no significant changed endpoints are presented in red, green, and dark blue, respectively
