ABSTRACT
his study investigates how Oreochromis mossambicus’s liver, brain, and gill tissues are affected by the pesticide acetamiprid following a 28-day exposure period. Commonly employed in agriculture, acetamiprid can infiltrate aquatic environments and have an impact on organisms that are not its intended target. Scanning electron microscopy was used to examine tissue samples, and Probit analysis was used to calculate the Lethal concentration (LC50). Hepatocyte enlargement and degeneration in the liver, brain cell atrophy and tissue collapse, and gill damage, including hemorrhages and epithelial rupture, were among the toxic consequences that were noted. These structural alterations suggest that acetamiprid presents a serious health danger to aquatic life and possibly to people who eat contaminated fish.
