Distribution pattern of heavy metals in the surficial sediment of Gorgan Bay (South Caspian Sea, Iran)
The Gorgan Bay is an important ecosystem receiving discharge from their tributaries. In this study, concentration of Pb, Zn, Ni, Fe, Al, Cu and As was seasonally determined at 22 sampling points during 2012-2013.Sediment samples were collected using a Van Veen grab. The levels of heavy metals were determined by ICP-AES (Inductively Coupled Plasma Atomic Emission Spectrometry) and AAS (Atomic Ab...

متن کاملDistribution and sources of polycyclic aromatic hydrocarbons in the surface sediments of Gorgan Bay, Caspian Sea.
The level and source of 16 polycyclic aromatic hydrocarbons (PAHs) were investigated in the surface sediments from the Gorgan Bay, Caspian Sea. The sum of 16 PAHs (ΣPAH16) concentrations varied from 107.87 to 516.18 ng g(-1)dry weight, with average value of 270.96 ± 150.47 ng g(-1)dry weight. Ecological risk assessment of PAHs, indicated that adverse biological effects caused by acenaphthene, n...
متن کاملPopulation dynamics of Caspian sand smelt (Atherina caspia) in Gorgan Bay-southeastern Caspian Sea
This study was carried out to investigate population dynamic of Caspian sand smelt (A. caspia) based on a monthly sampling in northern coast of Gorgan bay, between the estuary and canal of Khozeini, during its migration to coastal areas from March to September 2017. A total of 800 samples were collected using beach siene. Length frequency analysis revealed that there is significant difference b...
