). Spatial variations for different WWTPs are minor, except for one, which received high MCCP loads from 2002 to 2012. We assume that wastewater from a point source has reached this plant in those years. According to the levels of sludge from WWTPs, we conclude that the use of SCCPs in Swiss households and thus the exposure of people was reduced in the last three decades.
