Determinazione dei residui di Deltametrina nelle ciliegie

Abstract

This paper describes the determination of residues of the insecticide Deltamethrin in cherries growing in the Bonnanaro area near Sassari (Sardinia - Italy). The analytical procedure for the isolation of the insecticide was developed. The quantitative determinations were carried out by HPLC, with UV detector at 220 nm, on a Perkin-Elmer C18-HS3 column with acetonitrile - water (75: 25) as the mobile phase. A rapid decrease of the concentration of the insecticide with ti me was ascertained; three days after from the treatment the values were significantly lower than those required by the italian law
