Following airborne emission,  these particles  depositonto the earth’s surface where soil  and vegetation magnetic records readily reveal historical andrecent pollution patterns. However, as the preservation of magnetic particles on these receptors isaffected by PM deposition processes,  plant species,  local  geology, plant cover and land use,  theinterpretation of magnetic data is not straightforward, especially when large areas with high localvariability  are  surveyed.  Therefore,  the  application  potential  of  combined  soil  and  vegetationmagnetic mapping in Flanders is to be evaluated. Here, we investigate the PM pollution impact nearthe Ghent harbor area. Although robust topsoil magnetic records reveal a clear pollution pattern inforested area,  land use strongly  influences the dispersal  of  magnetic particles  through soil.  Thisimpedes  topsoil  records  to  delineate  large-scale  magnetic  footprints  and  necessitates  additionaldownhole magnetic measurements to facilitate interpretation. Vegetation magnetic data are hard tointerpret due to complex PM deposition processes and the influence of plant species. However, theuncovered pollution pattern is  distinct  from the soil  magnetic pattern,  possibly  reflecting recentchanges  in  PM  emission  and  suggesting  promising  potential  of  combined  soil  and  vegetationmagnetic monitoring in Flanders.
