The law describes a pesticide as a substance that prevents, destroys, repels, or mitigates a pest, or is a plant regulator, defoliant, desiccant, or nitrogen stabilizer. The use of pesticides has agricultural benefits such as controlling pest infestations. Many pesticides have been made illegal because of the long term effects on human health, but those same illegal pesticides have been found in crops long after their usage was terminated. Many farmers do not completely decontaminate their soil from past pesticides, so those dangerous pesticides remain in the soil and contaminate the crops. Using high performance liquid chromatography (HPLC), pesticides from agriculturally different soils were identified and isolated to determine what pesticide residue remained in the soil. The presentation highlights procedures, preliminary results and future work.
