Distribution of pyrethroids and piperonyl butoxide in foods and feeds analysed with GC-MS/MS in 2022-2023
The production of pesticides in the world is increasing, newly synthesized ones are replacing old ones, so pyrethroids should replace organophosphorus pesticides. As the pests become resistant, other compounds are added to the formulations in addition to pesticides; the function of these added compounds is to enhance the effect of active substances by slowing down their degradation in the pests. A wide range of products, from vegetables, fruits, animal feed, fish feed, teas, spices and honey to cereals, was analysed in order to gain insight into the distribution of pesticides, with special reference to pyrethroids and piperonyl butoxide in the analysed samples. The technique of gas chromatography with tandem mass detection (GC-MS/MS) was used for these analyses.
