The purpose of accomplished investigations was to determine physical and chemical indices of polyfloral bee honey and the presence of toxic elements, radionuclides and pesticides. Honey samples submitted by the economic agents to the Testing Laboratory of the Animal Origin Products of the Republican Veterinary Diagnostic Center during 2012-2013 have served as object of these investigations. It was revealed that the mass fraction of water in the investigated polyfloral honey constituted on

It was determined that the presence of toxic elementsin polyfloral honey is much lower than the admissible norms for this product, constituting on average: lead – less than 0,02- 0,024 mg/kg, cadmium– 0,004-0,009 mg/kg, arsenic – 0,011-0,031 mg/kg. The level of radionuclides constituted: cesium-137 – 3,26-3,422 Bq/kg, strontium-90 – 2,71-4,485 Bq/kg, hexachlorocyclohexane a, b, g – < 0,001 mg/kg; DDT and metabolites – < 0,005 mg/kg. Polyfloral honey obtained in the Republic of Moldova, according to the organoleptic indices, physical and chemical indices, the presence of toxic elements, radionuclides and pesticides, meets the required norms and is recommended for consumption. Rezumat. În studiul de faţă s-au determinat indicii fizico-chimici ai mierii poliflore şi prezenţa elementelor toxice, radionucleidelor şi pesticidelor. Ca obiect al investigaţiilor au servit mostrele de miere prezentate de agenţii economici în Laboratorul de Încercări ale Produselor de Origine Animalieră de la Centrul Republican Diagnostic Veterinar pe parcursul anilor 2012-2013. S-a relevat că fracţia masică de apă în mierea polifloră cercetată constituie, în medie, 16,61-16,87%, de zahăr invertit – 81,37-94,6%, de zaharoză – 1,52-1,97%, indicele [...]
