For the first time, scientists have detected airborne toxic chemicals known as medium-chain chlorinated paraffins (MCCPs) in the Western Hemisphere, according to a recent study. The unexpected discovery was made while researchers were analyzing air pollution data across the U.S.
MCCPs, commonly used in industrial applications like lubricants and flame retardants, are now suspected to be entering the atmosphere through fertilizer made from sewage sludge. ‘This points to a previously unrecognized pathway for environmental contamination,’ said one researcher involved in the study, who spoke on condition of anonymity due to ongoing investigations.
Environmental analysts note that while MCCPs have been regulated in Europe, their presence in U.S. air raises new concerns about chemical management policies. The EPA has yet to comment on whether this finding will prompt regulatory action.
Moving forward, scientists plan to expand monitoring efforts to determine the full extent of MCCP dispersion and potential health impacts.
