Resumen: In Mauritania, the dromedary breeding is the most widespread pastoral activity, and it is considered as the first source of animal protein; however, the research on meat is relatively rare compared with fish, especially in relation with the presence of trace metals. In this work, livers, kidneys, and muscles of 25 Camelus dromedarius were collected from butcheries in Nouakchott (Mauritania) between February and April 2020 to study the concentration of trace metals (three essential metals: cooper (Cu), iron (Fe), and zinc (Zn), and four toxic metals: mercury (Hg), arsenic (As), cadmium (Cd), and lead (Pb)). Statistical treatment did not show significant differences associated with age (P = 0.7004), sex (P = 0.9353), or type of diet (0.9951) in the found concentration of the target substances, but the differences were significant between metals and between organs (P < 0.0001). The mean concentrations of the essential metals were 0.80 mg/100 g for Cu, 6.02 mg/100 g for Fe, and 3.28 mg/100 g for Zn, and the ratios between these concentrations were significant (P < 0.0001 in all cases), with [Fe] > [Zn] > [Cu]. Cu was most concentrated in the liver, Fe in the kidney, and Zn in muscle. The mean concentrations of toxic metals were 0.055 mg/kg for As, 0.064 mg/kg for Cd, 0.040 mg/kg for Pb, and 0.027 mg/kg for Hg. They also exhibited significant difference between organs. Hg and Pb showed their largest concentrations in the liver, whereas As and Cd reached their maximum values in the kidney. Therefore, the found concentrations in all cases were lower than the admissible level of trace metals.
