U.S. News & World Reportsranking of states based on industrial pollution and associated health risks places Louisiana last, and toxic air pollution along its industrial corridor is rising, according to a recent analysis by ProPublica,The Times-Picayune, andThe Advocate. We have a five-alarm fire, and setting strong standards will help ensure the fundamental right of every family to have safe water flowing from their kitchen tap, he said. WebOn June 15, 2022, EPA released updated health advisories, warning that even small amounts of PFOS and PFOA are harmful to humans. DecaBDE is used as an additive flame retardant in plastic enclosures for televisions, computers, audio and video equipment, textiles and upholstered articles, wire and cables for communication and electronic equipment, and other applications. We found that from 2014 through 2021, 62% to 73% of reported fracks each year used at least one chemical that the Safe Drinking Water Act recognizes as detrimental to human health and the environment. Dr. Detlef Knappe is a Professor of Civil, Construction, and Environmental Engineering at NC State University. The toxicity of a substance is its ability to cause harmful effects. This action was based on the detailed information provided during the 60-day public comment period for EPAs October 2021 proposal. Well convert it to an HTML5 slideshow that includes all the media types youve already added: audio, video, music, pictures, animations and transition effects. The UN says that it expects the industrys global value of more than $5tn (3.9tn) to double by 2030 and to quadruple by 2060.
