Low-temperature clean-up method for the determination of organophosphorus insecticides in olive oil.
A simple, extremely low-cost method using low-temperature lipid precipitation has been developed for the rapid analysis of virgin olive oil for organophosphorus insecticides and triazine herbicides commonly used in olive groves. The method gives good clean-up for GC analysis with nitrogen-phosphorus detection and recoveries between 77 and 104%, with RSD values of 7-16%. Matrix enhancement was observed for some pesticides and metabolites.
