Mercury pollution for marine environment at Farwa Island, Libya

Mercury pollution for marine environment at Farwa Island, Libya

BACKGROUND Farwa is an Island in Libya receives petrochemical wastes generated from General Company of Chemical Industries (GCCI) since more than 40 years. AIM The present work aimed to determine the concentrations of mercury (Hg(+2)) in fish, marine plants and sediment collected from Farwa lagoon to evaluate effect of industrial wastewater from GCCI on the marine environment. METHODS Hundr...

Ecological aspects of mercury--selenium interactions in the marine environment.

In the marine environment, mercury is accompanied by selenium in all investigated species of mammals, birds, and fish--possibly due to a normal homeostatic regulation. It therefore seems likely that selenium will exert its protective action against mercury toxicity in the marine environment, decreasing its detrimental effects on reproduction, behavior, growth, etc. of the organisms and thus pro...

Effects of Oil Pollution on the Marine Environment

Pollution in the Gulf: Monitoring the marine environment

M ore than 2 years after the Gulf conflict, scientists are continuing to keep a close watch on marine pollution stemming from the war. Following the conflict in early 1991, major concern was raised worldwide when an estimated four to eight million barrels of crude oil were directly released into the Persian Gulf from the Sea Island terminal in Kuwait. Such amounts clearly made it the largest oi...

Gaseous elemental mercury in the marine boundary layer: evidence for rapid removal in anthropogenic pollution.

In this study, gas-phase elemental mercury (Hg0) and related species (including inorganic reactive gaseous mercury (RGM) and particulate mercury (PHg)) were measured at Cheeka Peak Observatory (CPO), Washington State, in the marine boundary layer during 2001-2002. Air of continental origin containing anthropogenic pollutants from the urban areas to the east contained on average 5.3% lower Hg0 l...
