Golden orfes were examined for uptake, distribution, and elimination of radioactivity administered in the form of a 14C-labelled fluorescent whitening agent (FWA) of the bis(triazolyl)stilbenedisulfonic acid type. Results of these studies are given below. Pilot trials using FWA concentrations of 10 and 100 ppb and a population density of 1 fish per liter show that an equilibrium between uptake and elimination of the FWA develops in the animals within a period of one week; i.e., the incorporated traces of the FWA are not irreversibly bound. The radioactivity is mainly located in the gall bladder and in the intestinal contents, as well as in the liver, throat, and gills. The muscular system (filet) is virtually free from activity. Approximately 1-2% of the FWA amount administered per animal (corresponding to the concentration factors of 7-14) can be temporarily detected in the fish. Radioactivity is eliminated comparatively quickly. Two days following the transfer of the fish into water free from FWA a concentration factor as low as 1 is reached, i.e. from this time the FWA concentration in the animals decreases to less than 10 resp. 100 ppb.
对金色圆腹雅罗鱼进行了研究，以检测其对以双（三唑基）二苯乙烯二磺酸型14C标记荧光增白剂（FWA）形式施用的放射性物质的摄取、分布和消除情况。这些研究结果如下。使用浓度为10和100 ppb的FWA以及每升1条鱼的种群密度进行的初步试验表明，在一周内动物体内FWA的摄取和消除之间会达到平衡；即，摄入的FWA痕迹不会被不可逆地结合。放射性主要位于胆囊、肠内容物以及肝脏、咽喉和鳃中。肌肉系统（鱼片）几乎没有放射性。每只动物施用的FWA量中约1 - 2%（对应于7 - 14的浓缩系数）可在鱼体内暂时检测到。放射性消除相对较快。将鱼转移到不含FWA的水中两天后，浓缩系数降至1，即从此时起，动物体内的FWA浓度降至低于10或100 ppb。
