The environmental geoscientists at the Centre for Microbiology and Environmental Systems Science (CMESS) focused on a variety of parameters that contribute to plastic pollution in farmland soils. They calculated for different scenarios whether nano- and microplastic particles transport pollutants to groundwater resources. The result shows: they do not. Audrey Desaulniers, Orcéine, Montreal) - Study shows that microplastics do not contribute to the mobility of organic pollutants in agricultural soils In agriculture, large quantities of nanoand microplastics end up in the soil through compost, sewage sludge and the use of mulching foils. The plastic particles always carry various pollutants with them. However, they do not transport them into the groundwater, as is often assumed. Environmental geoscientists led by Thilo Hofmann have now determined that the plastic particles release the pollutants in the upper soil layers: they do not generally contaminate the groundwater, but have a negative effect on soil microbes and crops.
