食盐,作为一种混凝土抗冻剂,常在寒区冬季施工中应用。除抗冻以外,食盐尚有加速混凝土凝结硬化的作用。但氯化物对钢筋有锈蚀作用,为了防锈,在食盐中需要加入2%的亚硝酸钠作为阻锈剂。1983年2月26日晚,我院收治因误食此类掺有亚硝酸钠的食盐而发生中毒26人,均为男性战士、干部,年龄18～28岁。当日下午该部炊事员误将某施工单位遗弃的混凝土抗冻剂当作食 Salt, as a concrete antifreeze, is often used in cold winter construction. In addition to antifreeze, salt is still accelerating the role of concrete condensation hardening. However, chloride has a rust effect on the steel, in order to rust, in the salt need to add 2% sodium nitrite as a rust inhibitor. On the evening of February 26, 1983, 26 cases of poisoning caused by eating such salt with sodium nitrite were treated in our hospital. All of them were male soldiers and cadres aged 18-28 years old. On the afternoon of the same day, the cooks mistakenly put concrete antifreeze, which was abandoned by a construction unit, for food
