Rau ntau tshaj li 75 xyoo, Kev kis kab mob mercury los ntawm Badger Army Ammunition Plant tau ua rau cov ntses thiab cov tsiaj muaj sia nyob hauv Lake Wisconsin, ua rau kev noj qab haus huv rau pej xeem muaj kev pheej hmoo. Kev tshem tawm kom muaj kev nyab xeeb ntawm cov khib nyiab pov tseg yog qhov xav tau los tiv thaiv tib neeg kev noj qab haus huv los ntawm kev kis tsis tu ncua.

Daim ntawv no ntawm mercury nthuav qhia qhov kev pheej hmoo loj tshaj plaws rau tib neeg kev noj qab haus huv los ntawm kev noj cov ntses tsis huv.
