حوضه‌ی خلیج فارس دارای حدود دو- سوم از ذخایر نفتی دنیا است و بسیاری از بوم‌سامانه‌‌های دریایی آن به‌طور جدی در معرض خطر آلودگی نفتی قرار دارند. بنابراین مطالعه برروی وضعیت آلودگی نفتی خلیج فارس از اهمیت بالایی برخوردار است. نیکل و وانادیوم از فراوان‌ترین فلزات تشکیل دهنده نفت خام هستند که حضور آنها در رسوبات دریایی بیانگر ورود آلاینده‌های نفتی به محیط است. بنابراین، فلزات نیکل و وانادیوم دو ش...

Nowadays, contamination of heavy metals in aquatic ecosystems is one of the major world problems in developing and developed countries. Among various aquatics, shellfish species, especially bivalves can be used as bioindicator, because of purification system, potential bioavailability of impurities in environment as well as accumulation of some heavy metals in their body. Among bivalves, oyst...

Heavy metals widely enter into aquatic ecosystems, and cause various environmental problems due to bioaccumulation and biomagnification in food chains. The accumulation of heavy metals in bivalve tissues is affected by a number of intrinsic and extrinsic factors such as physiological conditions, growth, seasonal changes, pH, salinity, temperature, genera and age. The present study investigated ...

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. Biot...

Background: Marine pollution is a global environmental problem that its monitoring by ideal biomonitors is of great importance. Marine organisms, especially mussels, have the ability to accumulate metals from the environment they can be considered as a biomonitoring agent. Methods: In this study, concentrations of heavy metals were measured in Saccostrea cucullata collected from seven sites on...
