某磷肥厂在生产硫酸过程中用钒触媒(含五氧化二钒(V_2O_5)7.5～8.5％)作为摧化剂(制成小粉笔状,具酸咸味)。因保管不当,被某村一小女孩拾去,在21名(男11、女10)小学生及幼儿(最小1.5岁、最大9岁)中传着吃。经1～2小时后逐渐发病。开始感头晕、乏力、呕吐、全身不适,继而腹胀、腹痛、频繁呕吐、腹泻、面色苍白、口唇青紫、精神淡漠、舌苔绿色(约50％患者出现此征,可能是口服V_2O_5后被还原成V_2O_3,并通过口腔唾液淀粉酶及细菌的作用而形成绿色钒盐)、舌乳头肿胀症状逐渐加重。其中有3例较重者处于昏睡状态,7例眼结膜充血,3例鼻 A phosphate fertilizer plant in the production of sulfuric acid process with vanadium catalyst (containing vanadium pentoxide (V_2O_5) 7.5 ~ 8.5%) as a catalyst (made of chalk, salty). Due to improper custody, she was picked up by a small girl in a village and pretended to be eating 21 pupils (male 11, female 10) and young children (minimum 1.5 years old and maximum 9 years old).
