Marine Debris and Trace Metal (Cu, Cd, Pb, and Zn) Pollution in the Stranded Green Sea Turtles (Chelonia mydas).

Marine debris and trace metals are among the common environmental contaminants known to affect marine organisms. In this study, the quantitative and qualitative aspects of marine debris levels and bioaccumulation of trace metals (Cadmium: Cd; Copper: Cu; Lead: Pb; and Zinc: Zn) were investigated in 42 green sea turtles (Chelonia mydas) stranded on the northern coast of the Sea of Oman. The greatest quantity of debris was found in the intestine, stomach, and esophagus of the animals, respectively.

Polycyclic aromatic hydrocarbons (PAHs) and some biomarkers in the green sea turtles (Chelonia mydas).

Selected blood biochemical parameters (Glutathione S transferase: GST; Alanine aminotransferase: ALT; Aspartate aminotransferase: AST; Lactate dehydrogenase: LD and glucose) and polycyclic aromatic hydrocarbons (PAHs) were measured in blood samples from 18 green sea turtles (Chelonia mydas) from the Iranian coastline on the northern shore of the Sea of Oman. Mean total PAH concentration in the blood samples was 17.802 ± 1.

Toxicity and Mechanisms of Action of Polycyclic Aromatic Hydrocarbon Pollution in Red Algae (Gracilaria corticata) from the Northern Coast of the Oman Sea.

The activities of selected biomarkers including 7-ethoxycoumarin-O-deethylase (ECOD) and glutathione S-transferase (GST) were measured in the red algae (Gracilaria corticata) obtained from the Oman Sea. Chemical analyses were used to assess the polycyclic aromatic hydrocarbons (PAHs) in the red algae. Total PAH concentrations in the red algae ranged from 3.

Application of biomarkers in brown algae (Cystoseria indica) to assess heavy metals (Cd, Cu, Zn, Pb, Hg, Ni, Cr) pollution in the northern coasts of the Gulf of Oman.

In this study, selected biomarkers-Phytochelatin (PC) and Metallothionein (MT)- were measured in the brown algae (i.e., Cystoseria indica) obtained from the Gulf of Oman.

Metals in Blood and Eggs of Green Sea Turtles (Chelonia mydas) from Nesting Colonies of the Northern Coast of the Sea of Oman.

The green sea turtle (Chelonia mydas) has been a species of global concern for decades. In this study, heavy metals (mercury: Hg; Cadmium: Cd; Lead: Pb; Copper: Cu; and Zinc: Zn) were measured in blood and three egg fraction of green sea turtles nesting on the northern coast of Sea of Oman. Heavy metals concentrations in blood, yolk, albumen, and egg shell ranged between 0.

Biochemical and histological changes in fish, spotted scat (Scatophagus argus) exposed to diazinon.

Pesticide accumulates in aquatic ecosystems and exerts toxic effects on aquatic animals. In this study, stress parameters and tissue histopathology under acute diazinon exposure were investigated in fish, scat (Scatophagus argus). Spotted scat was exposed to different diazinon concentrations (0, 10, 20, 30 μg L(-1)) for 24, 48, 72, 96 h.

Polycyclic aromatic hydrocarbons in the coastal sea water, the surface sediment and Mudskipper Boleophthalmus dussumieri from coastal areas of the Persian Gulf: source investigation, composition pattern and spatial distribution.

Background: Persian Gulf is an exposed and stressed area as a result of oil pollution and other fossil fuels containing PAHs. The susceptibility of using mudskippers to monitor marine pollution, like PAHs, points to the fact that mudskippers are able to accumulate and record the PAHs presented in the coastal environments.

Methods: Polycyclic aromatic hydrocarbons (PAHs) were examined in the coastal waters, the sediments and biota (i.

Effect of 16 pure hydrocarbons on the stabilization and lysis of fish (mudskipper: Boleophthalmus dussumieri) erythrocytes.

The in vitro effects of polycyclic aromatic hydrocarbons (PAHs) on erythrocyte membrane stability of the mudskipper (i.e., Boleophthalmus dussumieri) were tested by using field concentrations, acute and chronic potency divisor concentrations.

Evaluation of glutathione S-transferase activity as a biomarker of PAH pollution in mudskipper, Boleophthalmus dussumieri, Persian Gulf.

As an attempt to study on the biomarkers types to assess the specification of the pollutants and health status of marine ecosystems, sediments and biota (i.e., Boleophthalmus dussumieri) were collected from the Persian Gulf.

Application of biomarkers in mudskipper (Boleophthalmus dussumieri) to assess polycyclic aromatic hydrocarbons (PAHs) pollution in coastal areas of the Persian Gulf.

In this study, selected biomarkers-The retention time (RT) performed on haemocytes, the Erythrocyte Osmotic Fragility (EOF) and the Glutathione-S Transferase (GST) activity in the liver- were measured in mudskipper (i.e., Boleophthalmus dussumieri) obtained from the Persian Gulf.
