Abstract
|
The concentration of 19 metal and non-metal elements in two fishes (Liza subviridis and Sphyraena jello) and associated
sediment–seawater from the northern part of the Persian Gulf was measured. The samples were gathered from two industrial
ports, one commercial port, and one residential port. The metal accumulation in the muscle and liver of fishes was evaluated.
Nickel (mean 362.07–712.83 ?g/g) and chromium (mean 470.00–691.47 ?g/g) in sediment and zinc (mean 9.01–31.15 ?g/L)
and arsenic (mean 18.22–22.14 ?g/L) in seawater had the most abundancy among studied elements. The accumulation of
elements in S. jello (a pelagic species) was higher than L. subviridis (a demersal species). For both species, major elements of
S and Mg and trace elements of Fe, Al, Si, Zn, and Cu showed highest accumulation. Also, fish samples from EmamHassan Port
were more contaminated than other stations. Ecological indexes values have revealed a low to moderate elemental pollution of
sediment and fish samples in the north part of the Persian Gulf.
