In this paper, the accumulation of heavy metals of Nickel (Ni) and Vanadium (V) was measured in habitat sediments, mangrove roots and leaves (Avicennia marina). Besides, the transfer of Ni and V from the sediment to root and to the leaves in Nayband Bay and Qeshm Island were studied. The samples were gathered by Systematic-random Sampling using selective transects at 16 stations at the end of m...
Introduction: Cadmium (CD) and lead (Pb) are widely used in the industrial and refining activities and are frequently detected in sediments. The main objectives of this research were focused on determining the concentration of Cd and Pb in the sediments of Asaluyeh and compare them with other parts of the world. Materials and Methods: The concentrations of Pb and Cd in the sediments of Nayband ...
The status of metal concentrations including Pb, Cd, Cu, Ni, Zn and Fe in six species of Padina were determined in polluted (Nayband Bay) and unpolluted (Bostaneh port) areas on the Coast of the Persian Gulf. The mean concentrations of metals in the sediment of two locations were: Pb (12.64), Cd (3.59), Cu (21.74), Ni (17.00), Zn (32.00) and Fe (677.53) µg g-1 dry weight, respectively. In ...
Polycyclic aromatic hydrocarbons (PAHs) biodegradation in contaminated sediment is an attractive remediation technique and its success depends on the optimal condition for the PAH-degrading isolates. The aims of the current study was to isolate and identify PAHs-degrading bacteria from surface sediments of Nayband Bay and to evaluate the efficiency of statistically based experimental design for...
materials and methods phe degrading bacteria were isolated from surface sediments. isolated strains were then identified by biochemical and molecular (16s rdna gene sequence) analysis. rsm was employed to evaluate the optimum biodegradation of phe by the most effective isolated strain. the investigated parameters included the temperature, inoculum sizes, ph, nh4cl concentration, and salinity. o...
The toxicity of heavy metals in sediments of the Nayband Bay and Asaluyeh region and potential ecological risk to sediment organisms assessed. Three stations with different degrees of vulnerability of South Pars Oil and Gas Activities (1: Control - 2: medium affected and 3: severely affected) were selected in the study area. Sediment sampling at each station in both cold and hot seasons (2010) ...
Introduction: Heavy metals widely used in the industrial and refining activities are frequently detected in sediments. The main objectives of this research were focused on determining the concentration of Cd and Pb in the sediments of Asaluyeh and compare with the standard. Methods: The concentration of Pb and Cd in the sediments of Nayband Bay area (contaminated area) and Lavar-e Saheli (cont...
Parts of oil spills reach Iranian coastline along the Persian Gulf in the form of tar balls and scattered oilpatches. There are many published reports regarding oil spills reaching northern coasts of the Persian Gulf,but none report on the content of heavy metals associated with petroleum in sediments and plants ofcontaminated areas. This research was conducted to determine and map petroleum- r...
in this study, surface water samples were collected monthly from five stations inclduing nayband bay, assaloye, dayer, kabgan and bushehr from december 2012 to june 2013. sampling stations were chosen according to data being collected during algal bloom caused by cochlodinium polykrikoides in 2008. a total of 45 genera of phytoplankton belongs to four classes were totally identified accounting ...
