Fig. 4From: Proposal for a tiered approach to evaluate the risk of transformation products formed from pesticide residues during drinking water treatmentIdentification of potential vulnerable drinking water catchments based on DF distribution of a crop class. a Shows dilution factors considering crop type fruit trees and berry [equivalent to fagrLU in Eq. (2)] and hydrology factor [equivalent to fhydrology in Eq. (2)]. b Illustrates the cumulative frequency distribution of dilution factors from a. c Indicates the corresponding potential vulnerable drinking water catchments in EU identified by using exemplary the 10th percentile dilution factor value from bBack to article page
