As you’ve learned from other pages of our website, soil is a complex mixture of minerals, organic material, water, and various lifeforms. In its original state, soil was an uncontaminated substance covering the earth. But humans have intentionally and accidentally poured harmful products onto it in some areas. Although this chemical-specific approach will continue to be useful for addressing some important emerging contaminants, such as those mentioned above, it may not represent a sustainable approach for addressing low-level contamination with multiple chemicals that are now known to occur in many U.S. rivers, groundwater, and finished drinking by:

The main food contaminants come from anthropogenic substances like pharmaceuticals, pesticide residues, Maillard reaction products, and organic pollutants, and heavy metals, metalloids, marine biotoxins, and mycotoxins come from natural sources (Alvito et al., ).
