Faucets are also called faucets.

Among the unqualified products, 的所有项目 “材料卫生要求” 不合格, 14 批次的 “涂层、电镀层的耐腐蚀性能” 项目不合格, 和 10 批次的 “标记” 项目不合格.
不合格 “材料卫生要求” 就是俗称的重金属超标, 这将损害消费者的健康. 检验发现，本次抽检的产品中, zinc alloy materials were used as the main material of the products actually accounted for 50%. Zinc itself is a heavy metal, and excessive amounts can cause zinc fever. 第二, products with unqualified “涂层及电镀层耐腐蚀性能” are easy to rust after use. In addition to affecting the appearance, they may contain toxic components after corrosion. 例如, patina has strong toxicity.
