Lead-glaze Exposure & Studio Blood-lead Monitoring
铅釉暴露与工作室血铅监测

含铅釉(PbO 20–40%)粉尘经呼吸与手口摄入,铅在体内蓄积且无安全阈值共识。管理要点:釉料称混固定在通风柜内并湿法作业,含铅釉专用工具以颜色标识隔离;干扫禁止,改用湿布与 HEPA 吸尘;进食饮水前必须洗手,釉料区绝对禁食。个人防护 FFP3 半面罩;孕妇与备孕者调离铅岗。欧美车间空气铅行动值为 30 μg/m³,接触人员每年血铅检测,建议控制在 100 μg/L 以下;检测记录保存至少五年。无铅硼熔块釉已可覆盖大部分色域,优先替换。
Lead glazes (20–40% PbO) expose via inhalation and hand-to-mouth contact, and lead accumulates with no agreed safe threshold. Controls: weigh and mix only in a fume hood with wet methods, keep lead-glaze tools color-coded and segregated, ban dry sweeping in favor of wet wiping and HEPA vacuuming, wash before eating, and forbid all food in glaze areas. Wear FFP3 respirators; pregnant or trying-to-conceive staff move off lead work. Airborne action level is 30 μg/m³; annual blood-lead testing, ideally under 100 μg/L, with records kept five years. Lead-free borate frits cover most of the palette—replace first.
