In order to investigate the main sources of residual heavy metals in fruits and their effects on food safety,the contents of lead,cadmium,arsenic and mercury in common fruits such as apples,grapes and citrus were detected and analyzed by atomic absorption spectrophotometry.The results showed that the heavy metal residues in fruits mainly came from soil pollution,pesticide application,irrigation water and atmospheric sedimentation.There were significant differences in the content of heavy metals in different kinds of fruits,especially in the epidermis.The potential risk of heavy metal residues to human health was assessed by comparing with national food safety standards,and corresponding control measures and suggestions were put forward.
