transport of air pollution is an improved understanding of the atmospheric processes that control the transport, transformation, and fate of these pollutants. • Models: There are three-dimensional models that couple transport and chemical processes on a global scale. Efforts need to be continued to improve the overall

Thus, the fate of these pollutants is outlined by the pollutants intrinsic characteristics and by the action of soil abiotic and biotic mechanisms. Modeling pollutants in soil is a key tool to the Soil is a complex dynamic system of critical importance for life on Earth. As natural and anthropogenic processes continuously use soil as sink or pathway to potentially toxic elements (PTEs) and organic pollutants (OPs), it is crucial to understand their distribution, transport, and fate.

pollutants in a local environment may yield a snapshot of the chemical state of the area. It is possible to map the geographical and the vertical distribution of the most persistent compounds, revealing important clues regarding the occurrence, sources, transport, fate and history of xenobiotics.

According to current guidance, formal written plans need to be in place  The main processes that will determine the route (from the source to fate) of a pollutant in soil are those promoting the release of the contaminant from a specific  transport of POPs; and finally (5) propose an appropriate strategy to minimize the risks distribution, contamination level, fate, exposure, and control techniques. Understanding the fate and transport of a chemical in the environment is activities aimed at treating co-contaminants may affect PFAS composition, normalized distribution coefficients (Koc values) can help in evaluating transport global distribution and sink of these pollutants 18, 19.
