Fig. 2: Efficiency of nettle and reed fertilizers in the removal of POPs.

The relative abundance of POPs (Schymanski level 1) is given for the plant tissues (100%, light green) and their respective fertilizers to visualize the removal rate for each POP. The efficiency of fertilizers removing POPs from diverse families is depicted for (a) nettle fertilizer and (b) reed fertilizer (n = 3 biological replicates). Average removal rates of 95% (nettle) and 87% (reed) were obtained for POPs identified as level 1 according to the Schymanski classification. Absolute quantification is given in the Supplementary Table 1. Source data are provided as a Source Data file.
