Abstract:

Since heavy metals are considered as one of the major pollutants threatening, the main goal of this study was to bring out the concentrations of Pb, Zn and Mn in the surface sediments off Bushehr in the Persian Gulf. For this purpose, after collection of samples, the concentrations of the three metals in surface sediments were measured through the atomic absorption. The results were compared with the mean of the elemental concentrations of Earth’s crust, world’s sediments and other areas of the Persian Gulf.  Although the mean of concentrations in selected stations were higher than the Persian Gulf’s central section, in comparison with Earth’s crust and world’s sediments, it was revealed that the concentrations of Zn and Mn were much lower. Moreover, cluster analysis showed that the two elements, Zn and Mn, had the same behavior and the concentration of Pb was not changed by depth increase.

Assessing some heavy metals pollutions in sediments of the northern Persian Gulf (Bushehr province)

Background: Land and water pollution by heavy metals is a universal issue. Although the pollution affects all countries, but its range and severity vary hugely. The pollution of the marine environment by heavy metals is a worldwide problem. Marine sediments can be sensitive indicators for monitoring contaminants in aquatic environments. Methods: The concentration of 10 elements (As, Cd, Cr, Cu...

Polycyclic Aromatic Hydrocarbons in Offshore Surface Sediments of the Northern Persian Gulf, Bushehr Province

Polycyclic aromatic hydrocarbons (PAHs) are classified as an important category of semi-volatile and persistent organic pollutants. They cause environmental problems due to their toxicity and accumulation in sediments. In this research, offshore sediments of 19 stations in 8 transects of the Persian Gulf in Bushehr province were studied to assess the sources of PAHs. The extraction and clean up...

sedimentary and environmental geochemistry of metals in the surface sediments of the north-west of persian gulf (boushehr province area)

sediments are generally regarded as the sink for dissolved elements carried out to the sea by rivers. in order to study the source and mechanism of metal transport in sea water, 123 surface sediment samples were taken by using grab sampler in the northwest part of the persian gulf in summer. grain size analysis and geochemical analysis by icp-oes were carried out on samples after sample prepara...

Determination of heavy metals in Acanthopagrus latus (Yellowfin seabream) from the Bushehr seaport (coastal of Persian Gulf), Iran

In this study, bioaccumulation of lead, copper, cadmium, zinc and mercury in gill, liver and muscle of Acanthopagrus latus (Yellowfin seabream) was quantified. The concentrations of heavy metals were determined by using differential pulse anodic stripping voltammetry (DPASV) after wet digestion method. The result comprise of concentration level of Cu2+, Cd2+, Zn2+, Pb2+ and Hg2+ in ten differen...
