Environmental toxicity assessment of engineered nanoparticles manifest histo-hemato alterations to fresh water fish.

The present study rigorously examined the toxicological effects of nanoparticles (NPs), specifically nickel (Ni) and chromium oxide (CrO) NPs, synthesized under controlled conditions and characterized. To evaluate their potential environmental impact exposed the freshwater fish () to environmentally relevant concentrations of both NPs within a controlled laboratory conditions. Vital organs, including gills and liver were subjected to histopathological analysis, revealing profound alterations in tissue architecture that were distinctly correlated with pathological damage.
