The formation of bound pesticide residues can range up to 90% of the original amount applied [2]. Contrary to the other dissipation processes of pesticides in soils (mineralization, leaching, volatilization), the formation of bound residues leads to stabilization of the molecules that increases their persistence in the soil matrix. More information is needed on the binding processes and the chemical forms of the stabilized residues in order to evaluate the environmental risk associated with these residues and the time scale of their stabilization.
