(NBC News) Ohio Attorney General Mike DeWine sued agricultural giant Monsanto on Monday, alleging the company concealed dangers posed by a toxic chemical compound it manufactured for nearly a half century.
In the suit, filed in the Hamilton County Common Pleas Court in Cincinnati, prosecutors argued that the company should pay for the clean-up of what it says are dozens of rivers, lakes and other water bodies contaminated with polychlorinated biphenyls, or PCBs.
