Measurement of Some Heavy Metals in the Sediments and Sole Fish Euryglossa orientalis from the Musa Creek

Accumulation of heavy metals in contaminated sediments and Sole fish, Euryglossa orientalis from Musa estuary were investigated. For this purpose, the sediments and fish samples were collected from 10 sampling sites with different of sources pollution and ecological condition around the Musa estuary. The samples were analyzed by a cold vapor Atomic Absorption Spectrometer Leco AMA-254. Based results, metals concentrations were ranged from 0.06 to 8.34 mu g/g for Hg, 0.02 to 6.23 mu g/g for MeHg, 0.75 to 16.38 mu g/g for Pb, 22.04 to 79.42 mu g/g for Ni, 24.98 to 77.51 mu g/g for V and 0.05 to 0.93 mu g/g for Cd in sediment, and from 0.69 to 7.23 mu g/g for Hg, 0.67 to 4.87 mu g/g for MeHg, 16.34 to 58.45 mu g/g for Ni, 0.78 to 9.56 mu g/g for Pb, 6.78 to 53.22 mu g/g for V and from 0.08 to 9.56 mu g/g for Cd in tissues of the fish samples in all sampling sites. Results showed there were significant differences in metals values between liver and gill of fish species (P<0.05), that metals value was higher in liver in compare the gill fish. The analyses of Pearson correlation showed there was positive correlation between sediment and fish for metals concentration (r = 0.955). Analyses of geoaccumulation index and enrichment factor showed there was high pollution with anthropogenic sources in more sampling sites.

Automated summary

The study investigated the accumulation of heavy metals in contaminated sediments and Sole fish from Musa estuary. Results showed significant differences in metal values between the liver and gill of fish species, with higher metal concentrations found in the liver. Pearson correlation analyses revealed a positive correlation between sediment and fish for metal concentrations. Geoaccumulation index and enrichment factor analyses indicated high pollution with anthropogenic sources in multiple sampling sites.
