From: Evaluation of acute-to-chronic ratios of fish and Daphnia to predict acceptable no-effect levels
a Relationship between the acute (EC50) and chronic (NOEC) effect level of Daphnia for industrial chemicals (filled symbol) and pesticides (open symbol). b Relationship between the acute (LC50) and chronic effect level of fish (NOEC) for industrial chemicals (filled symbol) and pesticides (open symbol). The upper gray line indicates a similar acute and chronic effect value, whereas the lower gray line indicates a 100-fold lower chronic effect level compared to the acute effect level
