Abstract:The effective guidance to food safety of navel orange and pomelo from southern Jiangxi was achieved based on the determination of arsenic content and comparisons of the difference of arsenic accumulation in dif－ ferent parts of fruit. The determination of arsenic in pulp and peel of navel orange and pomelo was investigated by hydride generation -atomic fluorescence spectrometry （HG -AFS） after H2O2 -HNO3 digestion. Results showed that the arsenic contents in pulp and peel of navel orange and pomelo were lower than the limit of nation－ al food safety standard， Arsenic contents in pulp were significantly lower than in peel for both fruits， and arsenic content in pulp of navel orange was much higer than that of pomelo， whereas arsenic contents in peel for both fruits were no significant differences. Therefore， the pulp would be safer than peel for navel orange and pomelo from southern Jiangxi， and some components existed in pulp of pomelo can reduce the arsenic accumulation.
