Screening Method of Pesticide Residues in Bees

Abstract

The losses of bee colonies are of alarming proportion not only for bee-keepers and honey consumers but for agricultural production and the market itself as well. Since 2006, honey bees and other pollinators throughout the world have experienced ongoing and rapid population declines. The continuation of this crisis threatens the stability of ecosystems, the economy and our food supply, as one in three bites of food are dependent on pollinator services. The extraction and purification of bees samples were done by the QuEChERS method. The obtained extracts were analyzed by GC-MS, screening analysis of bees to the content of 927 pesticides.

Gubici pčelinjih društava su alarmantni ne samo za pčelara i potrošače meda, nego za poljoprivrednu proizvodnju uopšte. Od 2006. godine, pčele i drugi oprašivači širom sveta doživnjavaju stalan i veoma brz pad populacije. Nastavak ove krize, ugrožava stabilnost ekosistema, privrede i proizvodnju hrane, usled njihove zavisnosti od polinatora. U radu su analizirani uzorci uginulih pčela ekstrahovani i prečišćeni QuEChERS metodom, dok su dobijeni ekstrakti analizirani GC-MS skrining metodom na sadržaj 927 pesticida.
