Effect of burnt tire-ash (water-soluble fraction) on blood and histopathological markers in Clarias gariepinus

• Discarded burnt-tyre ash adds to the source of environmental pollution in the aquatic ecosystem. • Invitro exposure of water-soluble fraction of burnt-tyre ash affected hematological markers in Clarias gariepinus biomodel. • Moderate to severe histopathological lesions were evident in the fish, in a dose and time-dependent pattern. • The recovery of fish from the toxicant-induced impairment was not certain in just 14 days. Aquatic habitats serve as pollutant reservoirs and experience massive pollution disasters due to anthropogenic pressure. The effect of the Water-Soluble Fraction (WSF) of burnt tire ash (BTA) was investigated on Clarias gariepinus juvenile using blood biomarkers as well as liver and gill histology. The model fish were exposed to 5 % (0.56 g/L), 10 % (1.12…
