Environmental parameters as pH and nitrate significantly affect chemical composition of DOM

DOM molecular composition variation was apparent in the vertical stratification of undisturbed soils

DOM became less aromatic with depth inundisturbed soils

Stream DOM is mainly of allochthonous origin and predominantly derived from alongside stream subsoil/groundwater
