Bluefish (Pomatomus saltatrix), a very popular marine sport fish caught in Atlantic coastal waters, contain significant levels of polychlorinated biphenyls (PCBs). Since fish can be an appreciable portion of human and feline diets, a feeding study was conducted with cats fed exclusively bluefish for 86 days with determination of tissue concentrations of PCBs. The concentrations of PCBs in brain, liver, and fat were significantly higher (p = 0.01) in the fish-fed cats than in the control group using the Wilcoxon rank sum test. The highest PCB levels were in fat, the median concentrations being 48 and 0.61 ppm (dry weight) in the fish-fed and control cats, respectively. The significance of the results is discussed.
蓝鱼（Pomatomus saltatrix）是一种在大西洋沿海水域捕获的非常受欢迎的海洋游钓鱼类，含有大量的多氯联苯（PCBs）。由于鱼类在人类和猫科动物的饮食中占相当比例，因此进行了一项喂养研究，让猫只食用蓝鱼86天，并测定其体内多氯联苯的组织浓度。使用Wilcoxon秩和检验，喂食蓝鱼的猫的大脑、肝脏和脂肪中的多氯联苯浓度显著高于对照组（p = 0.01）。多氯联苯含量最高的是脂肪，喂食蓝鱼的猫和对照组猫的脂肪中多氯联苯的中位数浓度分别为48 ppm和0.61 ppm（干重）。文中讨论了这些结果的意义。
