接触机会汞矿开采、冶炼和成品加工;温度计、气压表、极谱仪等的制造维修和使用;整流器、石英灯等电气器材制造和维修;冶金工业用汞齐法提取金、银;化工生产中用汞作阴极电解食盐生产烧碱和氯气;生产含汞药物和试剂;塑料、染料工业用汞作催化剂;军工生产中用汞作起爆剂;口腔科医师用银汞齐补牙等。毒作用表现汞在常温下极易挥发,溅洒地面或桌面后,立即形成无数小汞珠,增加了蒸发的表面积;汞蒸气还易被墙壁或衣物吸附,形成持续污染车间空气的二次汞源。在生产条件下,金属汞主要以蒸气形式经呼吸道进入人体,引起急性和慢性中毒。急性中毒多是由于意外事故等原因造成大量汞蒸气的逸散而引起的。发病急,出现头晕、乏力、发热等。较突出的症状是口腔炎,表现为流涎,带腥臭味,牙龈红肿酸痛,出现灰黑色的汞线,并糜烂出血、牙松动。厌
Contact opportunities Mercury mining, smelting and finished product manufacturing; Thermometers, barometers, polarography and other manufacturing and repair and use; rectifiers, quartz lamps and other electrical equipment manufacturing and maintenance; metallurgical industry with amalgam extraction gold, silver; chemical production In the use of mercury as a cathode electrolysis salt production of caustic soda and chlorine; production of mercury-containing drugs and reagents; plastic, dye industrial mercury as a catalyst; military production of mercury as detonating agent; stomatologist with silver amalgam fillings and so on. Toxicity Mercury is highly volatile at ambient temperatures. Immediately after splashing the ground or the table top, numerous small mercury droplets are formed, increasing the surface area for evaporation. Mercury vapor is also easily adsorbed by walls or clothing to form secondary mercury that continues to pollute the workplace air source. Under production conditions, metallic mercury enters the body mainly as a vapor in the respiratory tract, causing acute and chronic poisoning. Acute poisoning and more due to accidents caused by a large number of mercury vapor caused by the escape. Emergencies, dizziness, fatigue, fever and so on. More prominent symptoms of stomatitis, manifested as salivation, stench, gums redness aches, gray-black mercury line, and erosion bleeding, loose teeth. Tired
