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.
