A 4-year-old, previously healthy boy experienced intermittent abdominal pain for several weeks. He was diagnosed with probable gastroenteritis, but his symptoms worsened. Laboratory tests revealed normocytic anemia, and an abdominal radiograph showed a metallic foreign body in the stomach, without evidence of obstruction. Endoscopy resulted in the retrieval of a quarter and a medallion pendant from the stomach. A venous blood lead level measurement was extremely elevated, at 123 microg/dL (level of concern: > or =10 microg/dL). The medallion was tested by the state environmental quality laboratory and was found to contain 38.8% lead (388,000 mg/kg), 3.6% antimony, and 0.5% tin. Similar medallions purchased from toy vending machines were analyzed and were found to contain similarly high levels of lead. State health officials notified the US Consumer Product Safety Commission, which resulted in a national voluntary recall of >1.4 million metal toy necklaces.
一名4岁、此前健康的男孩数周来间歇性腹痛。他被诊断为可能患有肠胃炎，但症状加重。实验室检查显示为正细胞性贫血，腹部X光片显示胃内有一个金属异物，无梗阻迹象。通过内镜检查从胃中取出了一枚25美分硬币和一个大奖章吊坠。静脉血铅水平测量结果极高，为123微克/分升（关注水平：≥10微克/分升）。该大奖章经州环境质量实验室检测，发现含铅38.8%（388,000毫克/千克）、锑3.6%和锡0.5%。对从玩具自动售货机购买的类似大奖章进行分析，发现其铅含量同样很高。州卫生官员通知了美国消费品安全委员会，结果导致全国范围内自愿召回超过140万条金属玩具项链。
