ABSTRACT
Agricultural production relies heavily on the use of pesticides, which may accumulate in soil and water, posing a significant threat to the global ecological environment and biological health. Butachlor is a commonly used herbicide and environmental pollutant, which has been linked to liver and kidney damage, as well as neurological abnormalities. However, the potential impact of butachlor exposure on the gut microbiota remains understudied. Thus, our aim was to investigate the potential negative effects of butachlor exposure on host health and gut microbiota. Our results demonstrated that butachlor exposure significantly reduced the host antioxidant capacity, as evidenced by decreased levels of T-AOC, SOD, and GSH-Px, and increased levels of MDA. Serum biochemical analysis also revealed a significant increase in AST and ALT levels during butachlor exposure. Microbial analysis showed that butachlor exposure significantly reduced the abundance and diversity of gut microbiota. Furthermore, butachlor exposure also significantly altered the gut microbial composition. In conclusion, our findings indicate that butachlor exposure can have detrimental health effects, including dysregulation of antioxidant enzymes, abnormalities in transaminases, and hepatointestinal damage. Furthermore, it disrupts the gut microbial homeostasis by altering microbial composition and reducing diversity and abundance. In the context of the increasingly serious use of pesticides, this study will help provide impetus for standardizing the application of pesticides and reducing environmental pollution.
