Which persistent organic pollutants can we map in soil using a large spacing systematic soil monitoring design? A case study in Northern France

► The soil concentrations of 90 molecules which are members of four families of POPs and two families of herbicides were measured across France as part of the French National Soil Monitoring Network (105 sites). ► We applied model-based geostatistic to forty nine molecules which were detected at mode than 50 sites and hence were suitable for spatial analyses. ► Lindane, DDT and DDD can be mapped.
