为了防止污染扩散，当地消防部门被迫倒入了大量的水解氯化铝，目的是让氧化铝与镉发生反应沉入江底。 反应形成的有毒化合物最后被从江底挖出来。
To stop the contamination from spreading, the local fire department had to add significant quantities of dissolved aluminum chloride, which binds to cadmium and settles on the river bottom. The toxic sediment will eventually be dredged.
