The toxic gas ethylene oxide, at levels thousand times higher than what is considered safe, was detected across parts of Louisiana with a cutting-edge mobile air-testing lab. Credit: Khamar Hopkins/Johns Hopkins University The toxic gas ethylene oxide, at levels a thousand times higher than what is considered safe, was detected across parts of Louisiana with a cutting-edge mobile air-testing lab. The concentrations found dwarfed Environmental Protection Agency estimates for the region. The findings, led by Johns Hopkins University environmental engineers, suggest significantly higher cancer risks for people who live near Read More
