Abstract The concentrations of arsenic and nine other metals in various of Thompson Seedless raisins from Turpan city (TPC), Tuokexun county (TKC), Shanshan county (SSC), Grape Valley (GV) and Hetian region (HTR), and other variety samples from GV were determined by the Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) and the Graphite Furnace Atomic Absorption Spectrometry (GF-AAS), and assessed for their quality by comparing element levels in samples purchased with permissible limits stipulated by various agencies and organizations. Certified plant reference material (GBW07605) was used in trace element recovery and method validations. The ranges obtained for the elements analyzed in mg/kg were as follows: arsenic ( P P
