- Executive summary:
Acute oral toxicity study was done in mouse usingNiobium pentoxide(1313-96-8).No mortality was observed at dose 4000mg/kg bw. Clinical signs like Behavioral,muscle contraction or spasticity liver (hepatitis i .e hepatocellular necrosis), in lungs, thorax, or respiration: acute pulmonary edema was observed in treated mouse. Hence, LD50was considered to be>4000mg/kgbody weight. When mouse was treated with Niobium pentoxide(1313-96-8)orally
