氯化氫氣體的毒性及不同濃度對(duì)人體的危害

時(shí)間:2011/12/1閱讀:2963
分享:
    氯化氫局部作用引起的癥狀有結(jié)膜炎、角膜壞死、損傷皮膚和粘膜,導(dǎo)致具有劇烈疼痛感的燒傷。吸入后引起鼻炎、鼻中隔穿孔、牙糜爛、喉炎、支氣管炎、肺炎、導(dǎo)致頭痛和心悸、有窒息感。咽下時(shí),刺激口腔、喉、食管及胃,引起流涎、惡心、嘔吐、腸穿孔、寒戰(zhàn)及發(fā)熱、不安、休克、腎炎 
    長(zhǎng)期接觸低濃度氯化氫可使皮膚干燥并變土色,也可引起咳嗽、頭痛、失眠、呼吸困難、心悸亢進(jìn)、胃劇痛等情況。而慢性中毒者的zui明顯癥狀是牙齒表面變得粗糙、特別是門牙產(chǎn)生斑點(diǎn)
    吸人氯化氫的患者應(yīng)立即轉(zhuǎn)移至通風(fēng)良好的無污染區(qū)安置休息并保持溫暖舒適,并速求醫(yī)診治。眼部受刺激時(shí)馬上用水充分沖洗后就醫(yī)診治。皮膚受刺激時(shí)速用水沖洗,再用肥皂洗凈后涂氧化鎂甘油軟膏,或者用大量水沖洗后用5%碳酸氫鈉水溶液洗滌中和,然后再用凈水沖洗。
