Abstract

This study aims to examine the restorative impact of corn cob biochar (CCB) on pendimethalin (PMD)-induced toxicity in Oreochromis niloticus. Fish were divided into four groups: the first control group without treatment, the second group (CCB) exposed to 10 g CCB/L, the third group (PDM) exposed to 0.355 mg PDM/L, and the fourth group (PDM+ CCB) receiving both 0.355 mg PDM/L and 10 g CCB/L for 30 days. PDM exposure resulted in behavioral alterations, low survival rate (73.33 %), hematological and biochemical impairments, increased oxidative stress, suppressed immunity, and histopathological damage in gill, liver, and brain tissues. Co-treatment with CCB significantly alleviated these effects, as evidenced by improved survival rate (88.88 %), hematological, biochemical, and antioxidant-immune parameters and reduced histopathological alterations. In conclusion, CCB demonstrated a promising potential to mitigate PDM-induced toxicity in O. niloticus by enhancing physiological, biochemical, and histological resilience.

玉米芯生物炭对尼罗罗非鱼（Oreochromis niloticus）减轻二甲氧甲烷引起的毒性的潜在影响：对血液、生化、抗氧化免疫参数和组织病理学改变的影响。

本研究旨在研究玉米芯生物炭（CCB）对二甲甲烷（PMD）诱导的nilochromis毒性的恢复作用。鱼被分为四组：第一组未处理，第二组（CCB）暴露于10 g CCB/L，第三组（PDM）暴露于0.355 mg PDM/L，第四组（PDM+ CCB）同时接受0.355 mg PDM/L和10 g CCB/L，持续30天。PDM暴露导致行为改变、低存活率（73.33%）、血液学和生化损伤、氧化应激增加、免疫抑制以及鳃、肝和脑组织的组织病理学损伤。与CCB联合治疗显著缓解了这些影响，证明了生存率（88.88%）、血液学、生化和抗氧化免疫参数的提高以及组织病理学改变的减少。综上所述，CCB通过增强niloticus的生理、生化和组织学恢复力，显示出减轻pdm诱导的毒性的潜力。

期刊介绍： Aquatic Toxicology publishes significant contributions that increase the understanding of the impact of harmful substances (including natural and synthetic chemicals) on aquatic organisms and ecosystems. Aquatic Toxicology considers both laboratory and field studies with a focus on marine/ freshwater environments. We strive to attract high quality original scientific papers, critical reviews and expert opinion papers in the following areas: Effects of harmful substances on molecular, cellular, sub-organismal, organismal, population, community, and ecosystem level; Toxic Mechanisms; Genetic disturbances, transgenerational effects, behavioral and adaptive responses; Impacts of harmful substances on structure, function of and services provided by aquatic ecosystems; Mixture toxicity assessment; Statistical approaches to predict exposure to and hazards of contaminants The journal also considers manuscripts in other areas, such as the development of innovative concepts, approaches, and methodologies, which promote the wider application of toxicological datasets to the protection of aquatic environments and inform ecological risk assessments and decision making by relevant authorities.
