In May 1989, four members of an 11-man crew of bricklayers in western Washington state developed symptomatic lead poisoning while replacing the brick lining of an acid-accumulation tank at a paper mill. Peak blood lead levels (BLLs) for the four workers ranged from 88 to 123 micrograms/dL. An investigation indicated the source of the lead exposure was a special brick mortar that contained 71% lead oxide and was formulated to resist the normally acidic environment of the tank.
1989年5月，华盛顿州西部一个由11名砖匠组成的施工队中的4名成员，在一家造纸厂更换酸液储存罐的砖衬时出现了有症状的铅中毒。这4名工人的血铅水平峰值在88至123微克/分升之间。一项调查表明，铅暴露的来源是一种特殊的砖灰浆，其中含有71%的氧化铅，是为抵抗储存罐通常的酸性环境而配制的。
