Abstract: (6027 Views) |
| Heavy metals are considered as pollutants that can accumulate in the
body of organisms and have damaging effects on their health. The
present study was conducted to evaluate the concentration of arsenic
in blue swimmer crab (Portunus pelagicus) in Asalouyeh coasts in
Boushehr province as bio-indicator for heavy metals. After identifying
different sources of pollution in the region, sampling was carried
out at four sampling stations over a three-months winter period in
2014. Arsenic analysis was performed using an atomic spectrophotometer.
The results showed that the mean concentration of arsenic
in the soft tissue of P.pelagicus in January, February and March was
0.17±0.09, 0.23±0.11 and 0.30±0.15 (mg/kg dry weight), respectively.
There was a significant difference between stations and between
months (P>0.05). The lowest concentration of arsenic was for station
3 (0.15±0.10) and the highest one was for station 3 (0.35±0.10).
Also, the results showed that arsenic concentrations in all stations and
months were lower than the reported standard levels. |
