Comparative Pathology of Prudhoe Bay Crude Oil and Inert Shell Sealants in Chicken Embryos
Pathological changes and body weights were compared in 9-day-old chicken embryos exposed to Prudhoe Bay Crude Oil (PBCO), pharmaceutical mineral oil, or a sealing film on the eggshell. Embryos exposed to 10 or 20 μl PBCO developed marked ascites or subcutaneous edema, extensive liver necrosis, dilat...
