According to a new study by the Union of Concerned Scientists, more than 14 million Americans live within just five miles of 104 cancer gas-emitting facilities. The study found that these commercial plants release large amounts of ethylene oxide. Ethylene oxide, a colorless gas known to cause cancer, is emitted by facilities that sterilize medical equipment and dried food products as well as by some chemical plants, posing a largely invisible and unrecognized threat to nearby communities. This Union of Concerned Scientists analysis finds that the facilities emitting ethylene oxide are disproportionately polluting communities of color, low-income communities, and non-English language-speaking communities. In addition, more than one-quarter of commercial sterilizers are located in “hotspots” where nearby residents are potentially exposed to ethylene oxide emissions from more than one facility—often without their knowledge.
