SEATTLE—Washington has become the first U.S. state to sue the agrochemical giant Monsanto over pervasive pollution from PCBs, the toxic industrial chemicals that have accumulated in plants, fish and people around the globe for decades. The company said the case “lacks merit.”
Democratic Gov. Jay Inslee and Attorney General Bob Ferguson announced the lawsuit at a news conference in downtown Seattle Thursday, saying they expect to win hundreds of millions or even billions of dollars from the company.
“It is time to hold the sole U.S. manufacturer of PCBs accountable for the significant harm they have caused to our state,” Ferguson said, noting that the chemicals continue to imperil the health of protected salmon and orcas despite the tens of millions of dollars Washington has spent to clean up the pollution. “Monsanto produced PCBs for decades while hiding what they knew about the toxic chemicals’ harm to human health and the environment.”
PCBs, or polychlorinated biphenyls, were used in many industrial and commercial applications, including in paint, coolants, sealants and hydraulic fluids. Monsanto, based in St. Louis, produced them from 1935 until Congress banned them in 1979.
According to the U.S. Environmental Protection Agency, PCBs have been shown to cause a variety of health problems, including cancer in animals as well as effects on the immune, nervous and reproductive systems.
