Lead poisoning adversely affects children worldwide. During 1999-2000, an estimated 434,000 children aged 1-5 years in the United States had elevated blood lead levels (BLLs) >/=10 microg/dL. Glazes found on ceramics, earthenware, bone china, and porcelain often contain lead and are a potential source of lead exposure. Children are especially vulnerable to the neurotoxic effects of lead. Exposures to lead in early childhood can have adverse effects on the developing nervous system, resulting in decreased intelligence and changes in behavior. In addition, certain behaviors (e.g., thumb sucking) place children at greater risk for exposure to lead. In 2003, the New York City Department of Health and Mental Hygiene's Lead Poisoning Prevention Program (LPPP), and the Mount Sinai Pediatric Environmental Health Specialty Unit (PEHSU) investigated a case of lead poisoning in a boy aged 20 months. This report summarizes that case investigation, which identified ceramic dinnerware imported from France as the source of lead exposure. This case underscores the susceptibility of children to a toxic exposure associated with 1) the high proportion of time spent in the home and 2) dietary habits that promote exposure to lead leached from ceramic ware.
铅中毒对全球儿童均有不利影响。在1999 - 2000年期间,美国估计有43.4万名1至5岁儿童的血铅水平(BLLs)升高,≥10微克/分升。在陶瓷、陶器、骨瓷和瓷器上发现的釉料通常含有铅,是铅暴露的一个潜在来源。儿童尤其易受铅的神经毒性影响。幼儿期接触铅会对发育中的神经系统产生不利影响,导致智力下降和行为改变。此外,某些行为(如吮拇指)会使儿童面临更高的铅暴露风险。2003年,纽约市卫生和精神卫生部门的预防铅中毒项目(LPPP)以及西奈山儿科环境卫生专科单位(PEHSU)调查了一名20个月大男孩的铅中毒病例。本报告总结了该病例调查情况,该调查确定从法国进口的陶瓷餐具是铅暴露源。该病例凸显了儿童因以下两点而容易受到有毒物质暴露影响:1)在家中度过的时间比例高;2)饮食习惯促使接触从陶瓷制品中溶出的铅。
