Essential and toxic elements in honeys consumed in Italy

Area of Science:

• Food Science
• Environmental Chemistry
• Analytical Chemistry

Background:

• Honey is a globally consumed natural product.
• Assessing heavy metal contamination in food is crucial for public health.
• Italian honey quality and safety require ongoing evaluation.

Purpose of the Study:

• To quantify essential and toxic elements (Fe, Mn, Cr, Cu, Zn, Hg, Cd, Pb) in Italian honey.
• To assess honey's physicochemical properties.
• To determine potential health risks associated with heavy metal content in honey.

Main Methods:

• Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for elemental analysis.
• Atomic Absorption Spectrometry with graphite tube atomization (AAS-GTA) for Lead and Cadmium.
• Standardized methods for measuring humidity, sugar content, pH, and acidity.

Main Results:

• Elemental concentrations varied based on foraging area, floral source, and water quality.
• Honey samples exhibited varying levels of heavy metal contamination.
• Physicochemical parameters indicated good overall honey quality.

Conclusions:

• Italian honey is of good quality but not entirely free from heavy metal contamination.
• Detected heavy metal levels are below thresholds posing significant health concerns.
• Monitoring elemental content in honey is important for consumer safety.
