Abstract

The hepatic activity of epoxide hydrolase, aldrin epoxidase, aminopyrine N-demethylase, 7-ethoxyresorufin O-deethylase, benzo(a)pyrene 3-hydroxylase and UDP glucuronyl transferase was determined in adult herring gulls (Larus argentatus) at various stages of the breeding season. 2. MFO activity was measured for adult Leach's storm-petrels (Oceanodroma leucorhoa), guillemot (Uria aalge) and Atlantic puffins (Fratercula arctica). For most assays the values were highest for the puffin. 3. MFO activity in both nestling and adult Atlantic puffins was determined. The degree of induction caused by a single internal dose of Prudhoe Bay crude oil in adult puffins and that caused by multiple internal doses in nestling puffins was measured.

摘要

在繁殖季节的不同阶段，测定了成年银鸥（Larus argentatus）肝脏中环氧水解酶、艾氏剂环氧化酶、氨基比林N-脱甲基酶、7-乙氧基异吩恶唑酮O-脱乙基酶、苯并(a)芘3-羟化酶和UDP葡萄糖醛酸基转移酶的活性。2. 测定了成年暴雪鹱（Oceanodroma leucorhoa）、海鸠（Uria aalge）和大西洋海鹦（Fratercula arctica）的混合功能氧化酶（MFO）活性。在大多数测定中，海鹦的数值最高。3. 测定了雏鸟和成年大西洋海鹦的MFO活性。测量了成年海鹦单次摄入普拉德霍湾原油内部剂量所引起的诱导程度，以及雏鸟多次摄入内部剂量所引起的诱导程度。
