From: An often-overestimated ecological risk of copper in Chinese surface water: bioavailable fraction determined by multiple linear regression of water quality parameters

Fig. 3

Species sensitivity distributions of toxicity of Cu to aquatic organisms, normalized by the MLR, BLM and hardness-based models under standard water quality conditions and compared to the toxicity data without considering water quality parameters. The abscissa is the concentration value, and the ordinate is the calculated cumulative probability (a). Risk quotients of Cu in China under a standard water quality parameter level, and comparison to without considering water quality parameters, along with different water quality parameter values (b). MLR = multiple linear regression. BLM = biotic ligand model. Standard = toxicity data normalized based on the target water quality parameters suggested in Additional file 1: Table S3. Raw = raw toxicity data without considering the water quality parameters
