[Rapid and direct lead determination in honey]

Area of Science:

• Analytical Chemistry
• Environmental Science
• Food Science

Context:

• Honey is a potential biological indicator for heavy metal contamination.
• Traditional sample preparation methods for honey analysis are time-consuming and prone to contamination or sample loss.
• Accurate heavy metal monitoring in honey is crucial for food safety and environmental assessment.

Purpose:

• To develop a novel method for measuring lead in honey without sample degradation.
• To simplify the analysis of honey for heavy metal contamination.
• To establish a reliable and efficient technique for monitoring lead levels in honey.

Summary:

• A new method utilizing Atomic-Absorption-Spectrophotometry with microprocessor-controlled graphite tube conditions allows direct measurement of lead in honey.
• This technique avoids the need for complex digestion, minimizing sample degradation, contamination, and loss.
• Satisfactory statistical variations of 8.3% (N=10) and 5.6% (N=22) were achieved for low and high lead content samples, respectively.

Impact:

• Enables faster and more reliable heavy metal analysis in honey.
• Reduces the risk of errors and sample loss during honey analysis.
• Facilitates the use of honey as a more accessible biological indicator for environmental lead contamination.
