铅是一种用途广泛的有毒金属,在生产中,工人接触若防护不善,可引起铅中毒。厂矿如果对“三废”处理不当,可严重污染周围环境,也能影响居民健康。 进入体内过量的铅能影响蛋白质的代谢,出现体重减轻和血液总蛋白下降。若膳食中蛋白质摄入量不足,使组织中铅的蓄积量上升。而蛋白质及蛋氨酸、胱氨酸等含硫氨基酸的摄入量的增加,可有效地阻抑慢性铅中毒的发生或减轻中毒症状。含蛋白质比较丰富的食品有鱼、肉、蛋、奶、豆类及其制品等。 钙与铅在体内有相似的代谢过程,凡能促使钙贮 Lead is a toxic metal with a wide range of uses. In production, workers may be exposed to lead poisoning if exposed to poor protection. If the factories and mines handle the “three wastes” properly, they can seriously pollute the surrounding environment and also affect the residents’ health. Excess lead into the body can affect protein metabolism, weight loss and decreased total protein in blood. If the dietary protein intake is insufficient, so that the accumulation of lead in the organization increased. The protein and methionine, cystine and other sulfur amino acids intake increase, which can effectively inhibit the occurrence of chronic lead poisoning or reduce the symptoms of poisoning. Rich in protein foods such as fish, meat, eggs, milk, beans and their products. Calcium and lead in the body have a similar metabolic process, where can promote calcium storage
