Background and Objective: Improper landfilling of drilling waste has adverse effects on the environment and human health. This study aims to select suitable landfills for oil and gas drilling waste on Qeshm Island using GIS and AHP. Materials and Methods: In this study, a weighted map was prepared based on each criterion affecting the site location. In the next step, each of the prepared layer...
The aim of this study was extraction of fucoxanthin pigment from brown algae Colpomenia sinuosa in Qeshm Island (winter, 2019) and to investigate its antioxidant effect. In order to extract fucoxanthin pigment, these algae were used in medium containing methanol solvent and by chromatography (HPLC), column 18 with fixed phase, Silica peak presence of fucoxanthin {RetTime} in 3,893 minutes and...
Fucoxanthin contents of four species of brown seaweeds (Dictyota indica, Padina tenuis, Colpomenia sinuosa and Iyengaria stellata) from intertidal zone of Qeshm Island, Persian Gulf were assessed in summer and winter of 2016. In addition, some physicochemical properties (pH, temperature, salinity and conductivity) of seawater were monitored on the same time. The antibacterial activity of algal ...
In this study 12 specimens were collected from Bandar Jask, Qeshm Island and Bandare Lengeh in Hormozgan Province. DNA extraction was performed using Phenol-Chloroform method. A partial DNA sequence of Cytochrome oxidase subunit I gene (COI) was used to evaluate genetic diversity. The sequence of Cytochrome oxidase subunit I gene was done using specific primers designed based on sequences regis...
Reproduction and spawning patterns of the Yellowtail scad (Atule mate) were studied in the Persian Gulf and Oman Sea (Hormozgan coastal waters) from December 2016 to November 2017. A total of 447 fish were collected from Bandar Lengeh, Qeshm Island, Bandar Abbas, and Bandar Jask landing sites.

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...
