Fig. 2: Detected Current Use Pesticides sum concentrations and number of residues.

Explicit results of the 78 sampling sites for the number and sum concentration of CUPs. Each of the six line transects consisted of 13 sample sites. In each tile, vegetation (bottom left), topsoil (bottom middle) and water (bottom right) and their corresponding sum concentration in ng g−1 in the cells above is mentioned (see tile description). Regions defined as valley and mountain region, Palatinate Forest and Black Forest and North and South. Site 1 was always closest to the Rhine in the valley, site 7 at the mountain foot and site 13 most remote in the mountain region. For details on the location of the transects see Fig. 1.
