Study bioaccumulation of heavy metals (Zn, Cu, Cd, Pb) in Metapenaeus affinis in Bahrekan, West-North of Persian Gulf
This study was conducted in order to bioaccumulation of heavy metals Zn, Cu, Cd and Pb in shell and muscle of white shrimp native species of Khouzestan Province in summer and winter of 2013, 80 samples were collected from station of Bahrekan in coast of Hendijan, West-North of Persian Gulf. Then Biometry and preparation of shell and muscle samples, metals were extracted using acid digestion method and concentration of heavy metals was measured by Atomic Absorption Spectrophotometer. Results showed that in shell and summer total of metals were higher than muscle and winter season and was significant relationships between them (P≤0.05). The maximum concentration of Zn in shell and two season summer and winter observed (44.61± 1.67 and 16.33±1.37 mg/kg dry weigh) and the minimum concentration of Cd (0.1±0.004 and 0.001±0.0001 mg/kg dry weigh) was determinate. There was a significant relationship between water and shrimp for accumulation of heavy metals in two seasons (P≤0.05). Results showed accumulation of Cd was higher than the NHMRC and the INSO standard.

| Summary: | This study was conducted in order to bioaccumulation of heavy metals Zn, Cu, Cd and Pb in
shell and muscle of white shrimp native species of Khouzestan Province in summer and
winter of 2013, 80 samples were collected from station of Bahrekan in coast of Hendijan,
West-North of Persian Gulf. Then Biometry and preparation of shell and muscle samples,
metals were extracted using acid digestion method and concentration of heavy metals was
measured by Atomic Absorption Spectrophotometer. Results showed that in shell and
summer total of metals were higher than muscle and winter season and was significant
relationships between them (P≤0.05). The maximum concentration of Zn in shell and two
season summer and winter observed (44.61± 1.67 and 16.33±1.37 mg/kg dry weigh) and the
minimum concentration of Cd (0.1±0.004 and 0.001±0.0001 mg/kg dry weigh) was
determinate. There was a significant relationship between water and shrimp for accumulation
of heavy metals in two seasons (P≤0.05). Results showed accumulation of Cd was higher
than the NHMRC and the INSO standard. |
