Revealed: Denka lobbied to undermine science behind ‘likely’ cancer-causing toxin

Chemical manufacturer launched aggressive campaign instead of reining in pollution, according to documents

Facing public pressure to rein in its pollution, a Japanese chemical manufacturer has instead launched an aggressive, years-long campaign to undermine the science showing that its compounds could cause cancer, according to newly released documents reviewed by the Guardian.

Chloroprene, the primary constituent of the synthetic rubber neoprene, is the major air pollutant in the town of Reserve, Louisiana, an area which according to the Environment Protection Agency has the highest risk of cancer due to airborne toxins anywhere in the US.
