在生活中,铅的用途广泛,如蓄电池、油漆、颜料、橡胶、印刷、铸字、电缆等都要用铅;陶瓷、玻璃、塑料的配料中亦含有铅的成份,故涂有各种颜色的儿童玩具、铅笔,印有彩色的图书报刊,盛放食物的彩釉容器,某些罐头食品,新油漆的家俱,室内装饰的塑料板、布等无疑都是铅污染的来源。同时外用含铅药物、染发剂、脂粉、唇膏等如果含铅量超标,也可引起生活性铅中毒,空气中的铅污染多数来自汽车排出废气中四乙基铅,在我们周围可以说无处不有铅污染。铅是一种淡灰色的有毒重金属元素,熔点较低,加热400～500℃即有大量的铅蒸气逸出,并在空气中氧化成颗粒极细的氧化
In life, lead is used in a wide range of applications, such as batteries, paints, paints, rubbers, printing, castings, cables, etc. Lead is also used in ceramic, glass and plastic ingredients, so it is painted in various colors Children’s toys, pencils, colored books and periodicals, colored enamel containers for food, some canned food, newly painted furniture, plastic sheets for interior decoration, and cloth are undoubtedly sources of lead contamination. At the same time topical lead-containing drugs, hair dyes, lipids, lip balms, etc. If the lead content exceeds the standard, can also lead to live lead poisoning, the majority of lead pollution in the air from the vehicle exhaust emissions of tetraethyl lead, around us can say nowhere No lead pollution. Lead is a light gray toxic heavy metal elements, low melting point, heating 400 ~ 500 ℃ that a large amount of lead vapor to escape, and in the air oxidation into fine particles of oxidation
