Figure 4From: Predicting the aquatic toxicity of commercial pesticide mixturesFrequency distribution of model distribution ratios (MDR) for fungicidal combination products. MDR was calculated based on the data set "most similar endpoints" using non-censored data only. Black represents products containing active substances with similar and white those with at least two active substances with dissimilar pesticidal modes of action. MDR values smaller than 1 indicate that the product is less and MDR values greater than 1 indicate that the product is more toxic than predicted, respectively. A, algal growth inhibition (n = 49); B, Daphnia acute toxicity (n = 43); C, fish acute toxicity (n = 42); D, Daphnia chronic toxicity (n = 14); E, fish chronic toxicity (n = 13).Back to article page
