Fig. 7From: Expected Risk as basis for assessment of safe use of chemicalsComparison of Risk Quotients and Expected Risks (A: RQNOEC vs. ERNOEC; B: RQNOEC vs. EREC50) of 1977 organic chemicals used in the EU. Each dot indicates one chemical. Curved lines represent quadratic regressions through substances of equal interspecies variance (σNOEC, σEC50) as published by Posthuma et al. [21]Back to article page
