Mesocosm experiments in the approval procedure for pesticides

Table 8.
Overview of raw data from the database for the PLS models developed for zooplankton. See Table 2 for abbreviations used. Sediment 1 refers to sediment present in mesocosm, 0 to no sediment; Macrophytes: 1 = present, 0 = no macrophytes, N= no information given on presence of marcophytes; Field/lab: 1 = Field study, 0 = Laboratory study. For all zooplankton groups the lowest effect concentrations observed for each taxonomic group in each mesocosm experiment were used as Y variables, expressing the toxic response of the organisms in the mesocosms (values shown in bold). L = Laboratory study at controlled temperature and light availability (hence latitude and longitude not relevant); F = flow-through study; - = no data. See Annex B for literature references.
