Sea Mammals and Oil: Confronting the Risks summarizes the effects of spilled petroleum, or "oil, on five groups of marine mammals, including seals, whales and dolphins, sea otters, polar bears, and manatees. It poses questions concerning the extent of oil spill effects on marine mammals; the vulnerability of each species; and the probable effects to humans, domestic animals, and laboratory animals. After an introduction to the composition and fate of petroleum and spill-treating agents in the marine environment, the book discusses the use of risk assessment and mathematical/computer models in evaluating the effects of oil in marine mammal populations. Chapters 3 to 11 examine the ecological perspectives, physiologic, and toxic effects of oil on five mammal groups. The effect of oil on their behavior and the detection and avoidance of oil spill are also discussed. With a strong focus on risk assessment, this book is ideal for petroleum chemists and technologists, marine biologists, and veterinary medicine researchers.
