Sažetak
Honey is a nutritionally valuable natural product of honey bees which can be contaminated by anthropogenic chemicals from the surrounding environment and beekeeper practices. Good beekeeping practice in conventional and regulations on organic beekeeping aim to reduce harmful residues in honey for human consumption. We compared prominent metal(loid) contaminant (Al, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) and acaricide (pesticides used for treatment of beehives for Varroa mite control) levels in 40 samples of Croatian chestnut honey (Castanea sativa) from Banovina region (Banski med ; 4 organic, 26 conventional) and Ozalj (2 organic, 8 conventional). Metal(loid)s were quantified using the Agilent 7500cx inductively coupled plasma mass spectrometer and acaricides using the Agilent Technology 1260 HPLC system coupled with a Triple Quad LC/MS 6410 mass spectrometer. All honey samples were safe for consumers regarding contaminant residues. Anti-varroa drug residues were not quantified in certified organic honeys (ORG), while amitraz (sum of parent compound and metabolites ; range: 0.007 ̶ 0.035 mg/kg), DMF (N- (2, 4-dimethylphenyl) formamide ; 0.005 ̶ 0.018 mg/kg) and coumaphos (0.005 ̶ 0.031 mg/kg) were detected in 9, 8 and 25 samples of 34 conventional honeys (CONV), respectively. Potentially toxic Cr was the only metal(loid) that showed a statistically significant difference between ORG and CONV (median 5.74 vs. 1.98 µg/kg, respectively ; U = 31, p = 0.009, Mann-Whitney U test) honey groups. On average, this small scale study found organic chestnut honey less burdened with acaricides and more contaminated with Cr residues than conventional honey.
