Spill by Means of Seabird Blood For example, lethal short-term effects of large oil spills often involve substantial seabird losses (9). Nonetheless, marine Analysis organisms can also become affected to the long-term exposure of the persistent and bioaccumulative components CRISTÓBAL PÉREZ,† of oil via several indirect processes mediated through the ALBERTO VELANDO,*,† ecosystem (10, 2).
