Chemieunfall im US-Bundesstaat West Virginia Ereignis

Officials said that up to 5,000 gallons of an industrial chemical used in coal processing seeped from a ruptured storage tank into the Elk River, just upstream of the intake pipes for the regional water company. Authorities struggled to determine how much danger the little-known chemical, MCHM, or 4-methylcyclohexane methanol, posed. The chemical, which smells like licorice, can cause headaches, eye and skin irritation, and difficulty breathing from prolonged exposures at high concentrations, according to the American Conference of Governmental Industrial Hygienists.
