Yellow eels (Anguilla anguilla L.) with an average weight of 50 g were caught in September in the Aveiro Lagoon on the Portuguese West Coast and kept in aerated aquaria for 1 week before the experiment started. The eels were exposed to an inorganic lead concentration of 300 micrograms Pb/liter for 30 days. Differential white blood cell count showed an increase in the number of lymphocytes in exposed fish. Blood hemoglobin and number of red blood cells per cubic millimeter showed no differences between the control and the exposed fish. Biochemical analyses of blood composition, such as plasma glucose, total plasma protein, total plasma cholesterol, and sodium and potassium plasma, showed no differences between treated and control animals. Plasma lactate levels increased in treated animals compared with those in controls.
平均体重50克的黄鳝（欧洲鳗鲡）于9月在葡萄牙西海岸的阿威罗泻湖捕获，并在实验开始前在充气水族箱中饲养1周。将这些黄鳝暴露于浓度为300微克铅/升的无机铅环境中30天。白细胞分类计数显示，暴露组鱼类的淋巴细胞数量增加。血液血红蛋白和每立方毫米红细胞数量在对照组和暴露组鱼类之间没有差异。对血液成分进行的生化分析，如血浆葡萄糖、总血浆蛋白、总血浆胆固醇以及血浆钠和钾，在处理组和对照组动物之间没有差异。与对照组相比，处理组动物的血浆乳酸水平有所升高。
