Abstract:The contents of the pollutant element, lead, in edible nuts were determined by flame atomic absorption spectrophotometry. The linear relationship over the range of 0.00-2.00 μg· mL-1 is good(r=0.999 1). The recovery is in the range of 94.0%-102.0% and the RSD is below 4.64%(n=5). The method is simple and the results are accurate. It can be used as a monitor method for lead in edible nuts. The results show that the pollutant element lead exists commonly in edible nuts. The plants were affected by water, soil and atomsphere during growing, and can absorb lead in environment.
