The lethal and histopathological impacts of crude oil's Water-Soluble Fraction (WSF) on the liver and kidney tissues of juvenile Rutilus frisii were investigated. The LC 96 h of WSF was calculated at 33.95 ppm. Fish exposed to two concentrations (0.1 LC and LC) of WSF and control for 24 and 96 h were used for histopathological studies. Tissues in the control group and 0.1 LC-24 h were healthy, and no specific damages were observed. With increasing exposure time (96 h) and concentration (LC), damages' type, frequency, and intensity gradually increased. Cloudy swelling, loss of cell boundary, nuclei deformation, and congestion of blood vessels were found in the liver, enlarged glomeruli, reduced Bowman's space, and occlusion of the tubular lumen, were found in the kidney. It is demonstrated that the WSF of crude oil can cause severe damage to the tissues of juvenile Kutum, depending on the exposure concentration.
研究了原油水溶性组分(WSF)对幼鱼鲁氏雅罗鱼肝脏和肾脏组织的致死和组织病理学影响。计算得出WSF的96小时半数致死浓度(LC96 h)为33.95 ppm。将暴露于两种浓度(0.1 LC和LC)的WSF以及对照组的鱼分别处理24小时和96小时,用于组织病理学研究。对照组和0.1 LC - 24小时组的组织健康,未观察到特定损伤。随着暴露时间(96小时)和浓度(LC)的增加,损伤的类型、频率和强度逐渐增加。在肝脏中发现了浊肿、细胞边界丧失、细胞核变形和血管充血,在肾脏中发现了肾小球肿大、鲍曼氏间隙减小和肾小管腔阻塞。结果表明,原油的WSF可根据暴露浓度对幼鱼库图姆的组织造成严重损伤。
