Heavy metal levels in elongate sole (Solea elongata Day, 1877) from the Korangi Fish Harbour, Karachi, Pakistan.
In this study, fish samples collected from Elongate Sole (Solea elongata Day, 1877) caught on the Korangi Fish Harbour in 2018 (South-west Monsoon and North-east Monsoon) were analysed to determine concentrations of heavy metals: Fe, Zn, Cu, Pb, Mn and Cd by an atomic absorption spectrophotometer, expressed per unit of dry weight of each sample. The average measured level of Fe, Zn, Cu, Pb, Mn and Cd for Solea elongata was 38.716±11.321 μg g−1, 16.638±3.344 μg g−1, 1.067±0.404 μg g−1, 0.022±0.043 μg g−1, 0.273±0.100 μg g−1 and 0.022±0.010 μg g−1, respectively. Although the contamination values obtained from Solea elongata are below the limits, it is important to follow the metal accumulation values.
