The sensor detects the organophosphate pesticide malathion in a selective and sensitive manner. Using cyclic voltammetry

• organophosphates are widely used due to their availability as efficient, low-cost pesticides. It is important to recognize, however, that excessive pesticide use poses a negative impact on the environment and human health because of biomagnification and persistence [3].

• /bjnano.13.65 Abstract Organophosphate-based pesticides (e.g., parathion (PT)) have toxic effects on human health through their residues. Therefore, cost-effective and rapid detection strategies need to be developed to ensure the consuming food is free of any organophosphate-residue. This work proposed

Conclusion Cu2O nanoparticles were used for the first time in the hydrolytic degradation of methyl parathion, the most neurotoxic organophosphate pesticide used to date.

• parathion (MP) is a very toxic organophosphate pesticide used as a non-systematic insecticide and acaricide on many corps. As MP and its by-products are highly toxic, they have to be retained to avoid pollution of rivers and lakes. Highly efficient sorbents are hydrotalcites (HTs) (or anionic clays). We

• degradation; mixed oxide; organophosphate; pesticide; water pollution; Introduction MP, an organophosphate, has been extensively used as pesticide since the 1970’s instead of chlorinated hydrocarbons (e.g., DDT). This pesticide is persistent and very toxic to humans and animals [1], even at low
