Abstract
Agriculture has gained increasing importance in response to the continuous growth of the world population and constant need for food. To avoid production losses, farmers commonly use pesticides. Mancozeb is a fungicide used in agriculture as this compound is effective in combating fungi that harm crops. However, this fungicide may also produce damage to non-target organisms present in soil and water. Therefore, this study aimed to investigate the influence of exposure to mancozeb on survival rate, locomotor activity, behavior, and oxidative status utilizing adult zebrafish (Danio rerio) as a model following exposure to environmentally relevant concentrations of this pesticide. The experimental groups were negative control, positive control, and mancozeb (0.3; 1.02; 3.47; 11.8 or 40 μg/L). Zebrafish were exposed to the respective treatments for 96 hr. Exposure to mancozeb did not markedly alter survival rate and oxidative status of Danio rerio. At a concentration of 11.8 μg/L, the fungicide initiated changes in locomotor pattern of the animals. The results obtained suggest that the presence of mancozeb in the environment might produce locomotor alterations in adult zebrafish, which subsequently disrupt the animals' innate defense mechanisms. In nature, this effect attributed to mancozeb on non-target organisms might result in adverse population impacts and ecological imbalance.

Reis Santos EL, Silva O, de Oliveira-Lima J, Camargo-Mathias MI. Effects of sodium dodecylbenzene sulfonate (SDBS), active principle of detergents, on the liver and kidney of zebrafish ( Danio rerio). INTERNATIONAL JOURNAL OF ENVIRONMENTAL HEALTH RESEARCH 2024:1-14. [PMID: 38902975 DOI: 10.1080/09603123.2024.2369221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Accepted: 06/13/2024] [Indexed: 06/22/2024]
Abstract
Sodium dodecylbenzene sulfonate (SDBS), a predominant component in detergents, requires an evaluation of its toxicological potential due to its hazardous environmental levels. Therefore, we evaluated the toxicological effects of SDBS on the liver and kidney of male D. rerio. Therefore, we evaluated the toxicological effects of SDBS on the liver and kidney of male D. rerio. The fish were divided into three groups: 0.0 (control), 0.25, and 0.5 mg/L of SDBS with exposure for up to 96 hours. After exposure, histopathological, histochemical (hepatic glycogen content), and biochemical analyses (SOD and CAT enzyme analysis) were performed on both organs. The results showed significant histopathological effects, such as circulatory disturbances and progressive and regressive alterations, leading to an altered histopathological alteration index. SOD and CAT enzymes exhibited prominent changes. Thus, it became clear that the surfactant SDBS can cause serious hepatic and renal problems in D. rerio fish, even with short-term exposure, necessitating more stringent control and regulation in the disposal of this surfactant.

Xenobiotica 2024; 54:150-159. [PMID: 38330245 DOI: 10.1080/00498254.2024.2316646] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Accepted: 02/06/2024] [Indexed: 02/10/2024]
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.
