MUTAGENICITY TEST OF HALOPREDONE ACETATE

The Journal of Toxicological Sciences, 1985
The mutagenicity of halopredone acetate (THS-201) was investigated by means of reverse mutation test in seven bacterial strains (S. typhimurium TA100, TA1535, TA98, TA1538, TA1537 and E. coli WP2, WP2 uvrA) and chromosomal aberration test in cultured Chinese hamster cells (CHL).

Bioremediation of Crystal Violet Dye Using Sapindus mukorossi Functionalized Iron‐Oxide Nanoparticles From Coprecipitation Method

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The textile industry is a water‐intensive industry that disrupts aquatic ecosystems by releasing recalcitrant chemicals like crystal violet (CV) dye characterized by its carcinogenic and mutagenic nature. Ethanolic extract of saponin‐rich Sapindus mukorossi was employed in the synthesis of biogenic iron oxide nanoparticles (IONP).
