We investigate the effects of PFAS on the solitary bee Osmia bicornis, by placing nests with pupae in an industry area with known very high PFAS-concentrations in the water, and in the agricultural areas with low concentrations as control. The map shows the location of the nest boxes.

Purple dots indicate location of Osmia nests in the “PFAS-area” (Kistinge industry) and green dots is the location of nests in the adjacent agricultural landscape.
