最近,我们收治了一位因长年吃爆米花引起铅中毒的4岁女童,再次提醒了我们铅的危害性。儿童正处于生长发育时期,不论急性慢性铅中毒都对儿童身体的多种系统产生不良影响,尤其是对神经系统、肾脏、造血系统及血管影响最大。慢性铅中毒多见于2～3岁以上幼儿,以学龄前儿童所占比例最大。从摄毒至出现中毒症状约经过3～6个月,表现为严重的中枢神经系统病变,如癫痫样发作、多动、语言发育障碍、攻击行为等。而智力发育落后将影响一个人的终生。当前,世界各国对儿童铅中毒的认识有很大改观,70年代科学家们诊断儿童铅中毒的标准是血铅浓度达60微克/公升,而今则规定此标准是10微克/公升。因为达到这一水准时,已构成对儿童生长发育及智力诸方面的损害。铅,可以说无所不在.只要在日常生活中稍不戒备,它就会偷袭儿童。比如生活中油漆无处不见,婴幼儿,尤其是刚刚出牙的孩子都喜欢啮物,带油漆的玩
Recently, we treated a 4-year-old girl who had been poisoned by lead popcorn for many years and once again reminded us of the dangers of lead. Children are in the period of growth and development. Regardless of acute chronic lead poisoning, they have adverse effects on various systems of children’s bodies, especially the nervous system, kidneys, hematopoietic system and blood vessels. Chronic lead poisoning more common in children aged 2 to 3 years to the largest proportion of preschool children. From poisoning to symptoms of poisoning after about 3 to 6 months, showed severe central nervous system diseases, such as epilepsy, hyperactivity, speech development disorders, aggressive behavior. And mental retardation will affect a person’s life. At present, the world’s awareness of lead poisoning in children has greatly improved. In the 1970s, scientists diagnosed lead poisoning in children as having a blood lead concentration of 60 micrograms / liter. Nowadays, the standard is 10 micrograms / liter. Because at this level, children’s growth and intellectual impairment have been compounded. Lead can be said to be omnipresent, and as long as it is less alert in everyday life, it can attack children. Such as paint everywhere in life, infants and young children, especially those who have just teeth toothbrush like to play with the paint
