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.

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.
