This research was conducted to study some chemical properties of frozen shrimp available in local markets, 24 samples were randomly collected for six imported commercial brands from Baghdad city markets, qualitative chemical tests were carried out, which included the values of pH, total volatile nitrogen (TVN)and thiobarbituric acid (TBA), heavy metals lead, cadmium and nickel were estimated, the results showed that there were significant differences at the level of (P≤0.05) in the values of TVN and TBA, the samples S1 and S3 exceeded the acceptable limits for TVN, reaching 33.28 and 32.71 mg N/100gm, TBA values for all shrimp samples were within the acceptable limits approved by Codex, with the highest value being 1.76, there were no significant differences between shrimp samples in the pH values, which ranged between 7.02 - 7.53, the concentrations of lead, cadmium and nickel elements recorded significant differences at the level (P≤0.05).  Samples S1 and S3 exceeded the acceptable limits for lead approved by Codex, which amounted to 0.337 and 0.660 mg/kg, while cadmium contents (0.082-0.142) were within Codex's (1 mg/kg) guidelines, they were greater than the European Commission's (0.05 mg/kg) permitted levels., all shrimp samples under study were within the acceptable limits for the element nickel.
