The object of the study were samples of different types of honey (acacia, linden, sunflower) collected from different soil-climatic zones (Southern, Central, Northern) of the Republic of Moldova. The content of trace elements in acacia, linden and sunflower honey was determined by atomic absorption spectrometry at the Institute of Chemistry of Moldova State University. It was found that the total amount of the studied trace elements in acacia honey from the Central Zone from rural areas was 8.056 mg/kg, and from urban areas - 22.22 mg/kg, or 14.164 mg/kg more. The micronutrient content of acacia honey from South Zone, rural area averaged 22.937 mg/kg or 14.881 mg/kg more than Central Zone and 0.717 mg/kg more than urban area. The total amount of trace elements in sunflower honey ranged from 8.50 mg/kg (Central Zone) to 10.52 mg/kg (Northern Zone) and in linden honey from 8.65 (urban zone) to 10.246 mg/kg (rural area). The highest amount of zinc was found in sunflower honey from Central zone with 1.15 mg/kg, copper with 1.21 mg/kg (Southern zone) and iron with 4.09 mg/kg (Northern zone). In linden honey from the Central Zone, the total amount of trace elements in the rural area was 10.246 mg/kg, ranging from 7.81 to 11.56 mg/kg; it was 1.596 mg/kg less in the urban area. The amount of trace elements in honey depends on the species of honey bearing plants and their growing area.
