ANALYSIS OF PESTICIDE AND HEAVY METAL RESIDUES IN HONEY BY GC/ECD AND GF-AAS: COMPARISON OF DIFFERENT PRODUCTION AREAS FROM ROMANIA
Abstract
Residues of pesticides and HM, used in bees care or in crop fields, have negative effects on the health of bees and humans and of the antimicrobial properties of the honey. Investigation of HM and pesticides is vital, since the use of chemical solutions has -rise up- significantly. Our aim was to investigate whether the level of contaminants in honey (Fe, Zn, Pb, Cu, Cd, As, using GC/ECD and GF-AAS) and pesticides: ?-HCH, ?-HCH, ? -HCH, aldrin, dieldrin, endrin, DDE, DDD, and DDT, alpha -Endosulfan, carbofuran, pirimicarb (by gas chromatography with electron capture determination). Iron (max. 0.76725 mg / kg), Zinc, Lead Copper Cadmium, Arsenic have lower values than the maximum allowed; 0.01 mg/ kg is the maximum allowed for pesticides; exception is max. 0.05 mg / kg for DDD, DDT, DDE, Carbofuran and Pirimicarb. The average of the resulting values exceeds the maximum allowed in many cases to four decimal places, as follows: Alpha HCH (max. 0.0158mg / kg), Beta HCH and HCH (by 10-15%), Aldrin (double), alpha endo-sulfan (three times than maximum). Endrin was not detected in any honey samples. Organochlorines in the pp DDE range were below the maximum (0.05 mg / kg). The pyrimicarbon showed lower values. The values determined are not dangerous for the human.
