The Pontchartrain Works facility owned by Denka in Reserve, Louisiana has been reported to be emitting chloroprene which is defined as “likely to be carcinogenic to humans” by the EPA.[7][8][9] Up to 755 times the safe air value of 0.2 μg/m3 of chloroprene has been recorded at the fifth ward elementary school in close proximity to the plant.[8] The cancer risk in Reserve is 1,500 times the national average and is thought to be due to chloroprene levels.[8] Denka has replied to the reports as being not based on “sound science”.[10]
