汞(水银)在室温下即能蒸发,温度越高,蒸发越快,汞滴易破碎,暴露面积愈大,愈易蒸发,同时,由于它比重大,附着力强,很易附着于墙壁、地板、衣服、用具上,钻入地板缝隙中不易清除,待温度升高时,蒸发为气态而污染空气。中心医院口腔科修补牙时常以白合金粉与汞在研钵内或手上研磨成汞齐(汞合金)而使用。研磨后,若有多余的汞就随手抛洒污染环境。检验科生化测定二氧化碳结合力
Mercury (mercury) can evaporate at room temperature. The higher the temperature is, the faster the evaporation is. The faster the mercury vaporization is, the easier the mercury drop is broken. The larger the exposure area is, the more evaporation is easy. At the same time, due to its large specific gravity and strong adhesion, Floor, clothes, utensils, drilling into the floor gap is not easy to remove, until the temperature rises, the evaporation of gaseous and pollute the air. Department of Stomatology, Central Hospital Tooth repair often white powder and mercury in the mortar or hand ground into amalgam (amalgam) and use. After grinding, if there is excess mercury readily throw pollution of the environment. Laboratory biochemical determination of carbon dioxide binding
