Abstract

1. Sodium dodecylbenzene sulphonate (SDBS) is one of the surfactants used worldwide in detergents which, due to high residual discharges, has great potential to cause ecotoxicological impacts. Therefore, the sublethal effects of SDBS on the gills and skin of male Danio rerio fish were investigated.

2. The fish were distributed into three groups: GC (control), GT1 (0.25 mg/L of SDBS), and GT2 (0.5 mg/L of SDBS) and exposed for 21 days. After the experiment, histopathological analyses of the gills, histochemical analyses (counting of mucous cells), and biochemical analyses (antioxidant defense enzyme analysis, SOD, and CAT) were conducted.

3. A significant increase (p < 0.05) in the incidence of circulatory disorders, progressive, and regressive alterations occurred in the GT1 and GT2 groups. Due to these changes, the total histopathological index of the gills was higher in these groups. Mucous cells in the gills and skin increased. There was an increase in SOD activity and a reduction in CAT activity in these groups. Haematology revealed neutrophilia and lymphocytosis in the blood of GT1 and GT2.

4. The results clearly demonstrate that a 21-day exposure to SDBS causes severe morphophysiological damage to the gills, skin, and blood of D. rerio fish.

洗涤剂中的十二烷基苯磺酸钠（SDBS）：对 D. rerio 鱼鳃、皮肤和血液的作用。

十二烷基苯磺酸钠（SDBS）是全球范围内用于洗涤剂的表面活性剂之一，由于其残留量高，对生态毒理学的影响潜力巨大。因此，研究了 SDBS 对雄性 Danio rerio 鱼鳃和皮肤的亚致死效应：将鱼分为三组：GC 组（对照组）、GT1 组（0.25 mg/L 的 SDBS）和 GT2 组（0.5 mg/L 的 SDBS），暴露 21 天。实验结束后，对鱼鳃进行了组织病理学分析、组织化学分析（粘液细胞计数）和生化分析（抗氧化防御酶分析、SOD 和 CAT）。

期刊介绍： Xenobiotica covers seven main areas, including:General Xenobiochemistry, including in vitro studies concerned with the metabolism, disposition and excretion of drugs, and other xenobiotics, as well as the structure, function and regulation of associated enzymesClinical Pharmacokinetics and Metabolism, covering the pharmacokinetics and absorption, distribution, metabolism and excretion of drugs and other xenobiotics in manAnimal Pharmacokinetics and Metabolism, covering the pharmacokinetics, and absorption, distribution, metabolism and excretion of drugs and other xenobiotics in animalsPharmacogenetics, defined as the identification and functional characterisation of polymorphic genes that encode xenobiotic metabolising enzymes and transporters that may result in altered enzymatic, cellular and clinical responses to xenobioticsMolecular Toxicology, concerning the mechanisms of toxicity and the study of toxicology of xenobiotics at the molecular levelXenobiotic Transporters, concerned with all aspects of the carrier proteins involved in the movement of xenobiotics into and out of cells, and their impact on pharmacokinetic behaviour in animals and manTopics in Xenobiochemistry, in the form of reviews and commentaries are primarily intended to be a critical analysis of the issue, wherein the author offers opinions on the relevance of data or of a particular experimental approach or methodology
