Yessi Pratiwi — January 25, 2008 / 11:25 pm
Scientists in Spain reported, seagulls may become living sentinels to monitor oil pollution levels in marine environments.
Alberto Velando and colleagues as the team of researchers, measured PAH levels in the blood of Yellow-legged gulls living in the vicinity of the oil spill caused by the 2002 shipwreck of the Prestige, one of Europe’s largest oil spills. Before, researchers have known for years that large oil spills can increase levels of polycyclic aromatic hydrocarbons (PAHs) in marine environments. The research showed, the level of PAHs in the bird’s blood is twice than usual.
The findings give support to the nondestructive use of seabirds as biomonitors of oil pollution in marine environments.
