1.当其以五氧化二钒的浓度为0.027mg/m~3给动物作慢性的昼夜吸入染尘70天时,便引起机体的机能状况的重要变化。甚至引起某些内部器官的病理性改变。 2.在连续40天吸入染尘五氧化二钒浓度为0.006mg/m~3的条件下,在采用机能饥饿负担之后,会导致大白鼠的机能状态的重要变化。 3.当五氧化二钒的浓度变为0.002mg/m~3作慢性昼夜染尘70天的条件下,在研究哺乳动物机体的机能方面表明是无效的。
1. When it is given to animals at a concentration of 0.027 mg / m3 of vanadium pentoxide for chronic diurnal aspiration for 70 days, significant changes in the functional status of the body are caused. Even cause some pathological changes of internal organs. 2. In 40 consecutive days of inhaled dust vanadium pentoxide concentration of 0.006mg / m ~ 3 conditions, the use of functional hunger burden, will lead to important changes in the functional status of rats. 3. When the concentration of vanadium pentoxide becomes 0.002 mg / m 3 for chronic diurnal dusting for 70 days, it has been shown to be ineffective in studying the function of mammalian organisms.
