For the second Norwegian Moss survey on organic contaminants 20 samples were collected on the Norwegian mainland in rural areas presumably little affected by local point sources of pollutants.
PeCB, HCB, PCB, HCH, DDT, PBDE, DBDPE, HBCD, PFAS, and PAH were determined. There is a general trend of decreasing contamination from 2010 to 2015 for the POPs included in the survey. A trend of decreasing contamination with increasing latitude shown in the 2010 moss data is confirmed in the results from 2015. The results for PCB indicate release from local sources in the Oslo area.
