Abstract
Human activities are the cause of dispersion of dangerous pollutants. Biocides, such as parathion, and heavy metals such as copper, are very demonstrative examples. Parathion and its derivatives are potent insecticides and fungicides. However, they are extremely toxic to all forms of animal life, and this because of their chemical nature, they are phosphorothioates. Copper salts are persistent and widespread polluants, which in high concentrations are harmful to mammals and highly toxic to marine organisms. For the first time, it is proposed to combine two innovative and sustainable strategies to remediate mineral and organic pollution. Aquatic hyperaccumulators of copper are used to phytoextract salts of Cu(II) in pools mimicking contaminated areas. Biomass loaded with metal salts is then transformed into a catalyst for hydrolysis of parathion. A 31P NMR study clearly shows that copper salts derived from vegetables accelerate the degradation of parathion unequivocally.
