Abstract: No digestion and direct determination of lead in honey by graphite furnace atomic absorption spectroscopy (GF-AAS). The influence of instrument parameters and chemical modifiers were investigated.The detection limit of the lead is 0.65μg/L; The relative standard deviations is 1.4%~9.5%. The recovery is in the rage of 96.8%~109.0%. This method has advantages of simple operation and high efficiency was compared with national standard testing method.

Key words: lead, GF-AAS, honey
