铅矿开采冶炼、蓄电池、浇铅网络板、牙膏管和铅管、印刷业铅板、铅字浇铸、造船厂涂铅板的风割和敲铲、含铅油漆颜料的生产及使用、陶瓷的配釉、玻璃及塑料制造的配料等均要接触铅。如果防护条件差或预防措施不恰当,铅及其化合物的蒸气、气溶胶或粉尘就会从呼吸道、消化道进入体内,引起急性或慢性铅中毒。铅的溶点是327℃,当加热到400～500℃时就会散发出大量蒸气,并随温度升高而增多。铅蒸气在空气迅速凝聚,氧化而成氧化铅,呈气溶胶状态,吸入人体内对组织有很强的粘性,不易排除,因而铅蒸气的毒
Lead mining and smelting, storage batteries, pouring lead network board, toothpaste tubes and plumbing, printing industry lead board, lead casting, shipyard coated lead wind cutting and shovel, lead paint paint production and use of ceramic with Glaze, glass and plastic ingredients, etc. must be exposed to lead. If the protective conditions are poor or precautionary measures are inappropriate, the vapor of lead and its compounds, aerosols or dust from the respiratory tract, digestive tract into the body, causing acute or chronic lead poisoning. Lead melting point is 327 ℃, when heated to 400 ~ 500 ℃ will emit a lot of steam, and increased with increasing temperature. Lead vapor in the air quickly condensed, oxidized into lead oxide, aerosol state, inhaled the body has a strong adhesive to the organization, not easy to rule out, so the toxicity of lead vapor
