Demand Chemical Plant Stop Emitting Deadly Carcinogen

Target: Shinsuke Yoshitaka, President and CEO, Denka Company

Goal: Ensure emission of the EPA branded carcinogen called chloroprene is stopped at Denka chemical plant.

Since 1969, the Denka chemical plant in Louisiana has emitted a known carcinogen called chloroprene, which may have caused a range of chronic illnesses and associated premature deaths in the surrounding community. Since widespread production of the chemical began in the 1930s there have been persistent safety concerns regarding human exposure. Reports from employees at chemical giant DuPont revealed that exposure to chloroprene gas had caused dizziness, nausea, heart palpitations, and a rapid pulse.

Residents of St. John the Baptist parish, lying directly adjacent to the chemical plant, have been impacted by decades of exposure to chloroprene. Interviews conducted by The Intercept revealed that most were either directly related to or knew someone who died prematurely from a serious chronic illness such as cancer. A study conducted by the Environmental Protection Agency supports the conclusion that this pattern is not just an unfortunate coincidence. Its review found that parish residents have by far the highest cancer risk due to air pollution in the United States.

There does not appear to be any forthcoming government action to address chloroprene emissions, as the Trump Administration has initiated a sweeping rollback of environmental regulations. This includes a steep budget cut for the Integrated Risk Information System, the department within the EPA which first classified chloroprene as a human carcinogen. Please sign the below petition demanding that the current plant owner, Denka Company, cease all emissions containing chloroprene.


Dear Mr. Yoshitaka,

I am writing to demand that Denka Company end production of chloroprene. It is a toxic chemical which has been designated as a cancer-causing agent in humans.

Residents in the surrounding area have suffered from severe health issues due to decades of exposure to chloroprene. In fact, a study by the Environmental Protection Agency found that this community has the highest risk of developing cancer due to air pollution in the United States.

You have a moral obligation and fiduciary responsibility as President and CEO to discontinue business practices that endanger public health.

  1. The Denka chemical plant should be held accountable for the illnesses and premature deaths they have caused. It’s a disgrace that Trump is cutting funding to the EPA department that would and should deal with this issue.

  2. RoseMarie Dorer says:

    Just because the brainless, dimwitted, idiot-in-chief doesn’t understand what damage chemicals do to our air, water, and land that grows our food, much less to wildlife, doesn’t mean it’s okay to destroy the planet to line the pockets of the cheap, greedy companies who want to pollute the world.
