Concentrations of nine metals were measured in eight common cultured fish species obtained from forty-three aquatic product markets across three cities in Xinjiang province, to establish fingerprint characteristics and assess potential human health risks due to the consumption of fish. Metal levels ([Formula: see text] g/kg, wet weight) in fish muscles were: 1204.88–5113.19 Al, 2.09–12.44 V, 6.10–31.86 Cr, 2368.80–8949.52 Fe, 2.01–10.26 Co, 4082.72–12785.68 Zn, 174.89–763.83 Cu, 0.33–2.24 Cd, and 5.74–9.90 Pb. Fingerprint analysis revealed that the studied fish species from the three cities exhibited a similar pattern of distribution. From the viewpoint of human health, the assessment of non-carcinogenic risk indicated no significant adverse health effects due to consumption of the assessed fish species.

Food safety is increasingly elicited attention with China's rapid economic growth However, identifying the fish geographical origins based on muscles are unknown. 36 Trace metals are natural constituents of the earth's crust and ubiquitous throughout 37 the environment (Pan and Wang, 2012; Wedepohl, 1995) . Trace metals present in the 38 environment, originate primarily from natural processes but can also result from the 39 accumulation of metals released from anthropogenic activities (Hu and Cheng, 2013). 40 The major anthropogenic inputs of trace metals to the environment are via fossil fuel, Guideline China a n.a n.a 2000 n.a n.a n.a n.a 100 500 FAO b n.a n.a n.a n.a n.a 30000 30000 500 500 the three cities of Xinjiang province are illustrated in Fig.3 

Aquatic product quality safety has become a major health concern worldwide. In 225 the present study, an investigation into the concentrations of trace metals in fish species 226 was performed, using commercially available fish samples from three cities in Xinjiang.

The overall mean trace metal concentrations were ranked in the order: Zn > Fe > Al >
