Abstract:

This study is an attempt to evaluate the biomonitoring capabilities of rock oyster, Saccostrea cucullata, for mercury (Hg) pollution. The oyster and sediment samples were collected from 10 rocky habitats of Qeshm and Hormoz Islands in the Persian Gulf. The concentration of mercury in the shell and soft tissues of the oysters and sediments were analyzed using an advanced mercury analyzer. Biota-sediment accumulation factor (BSAF) was calculated based on the ratio of Hg concentrations in soft tissues to that in sediments. The results showed that the rate of mercury accumulation in the soft tissues of the oyster was significantly higher than that in its shell (P < 0.05). There was a significant correlation between mercury concentrations in the soft tissues and the sediments (r =0.75) According to BSAF, soft tissues of the oyster were recognized as an appropriate indicator for biomonitoring mercury. The present study generally supports the usability of soft tissue of S. cucullata as a sensitive biomonitoring organ to warn us of mercury pollution in the Persian Gulf.

Length-Weight relationship, Condition factor and length frequency of rock oyster, Saccostrea cucullata in coastal waters of Persian Gulf

This study aimed to achieve length frequency, condition factor and length-weight relationship of the rock oyster, Saccostrea cucullata in the coastal waters of Persian Gulf. Sampling was carried out by 0.25 m2 quadrat through intertidal zone from winter 2015 to autumn 2016. According to the results, length-weight relationship calculated as W=0.000004L2.79 for both sexes. In addition, coefficien...

a genotoxicological study in persian gulf on rock oyster (soccostrea cucullata) using micronuclei and rapid assays

both micronuclei (mn) and binuclei (bn) as well as rapd (random amplifying polymorphism of dna) assays are newly biomarkers which are well-introduced in toxic injury and related genotoxicity studies in bivalve, fishes and even humans. however, there is no record of such studies in iranian persian gulf coast line so far. for this propose, we analyzed frequency of mn and rapd patterns in gill cel...

Evaluating Total Mercury and Methyl Mercury Contents in Canned Tuna Fish of the Persian Gulf

Due to hygienic risks of mercury residues in food and marine originated supplements, measuring total mercury and methyl mercury contents of canned tuna as a highly consumable marine food product is essential. In this study, 40 canned Tuna fish (from Persian Gulf) were collected in 2015 and then flame atomic absorption spectrometer (FAAS) and thermo gas chromatography mass spectrophotometry were...
