From the Road to the Field: Decoding Chemical Transformation in Aging Tire and Artificial Turf Crumb Rubber.

ABSTRACT: Increasing tire use worldwide raises concerns about the health impact of rubber-derived chemicals. Of particular concern is the aging of these chemicals, which may lead to the formation of unknown, potentially harmful transformation products. Existing studies have not comprehensively assessed different aging mechanisms and their impact on rubber-derived chemicals from tires from various sources. To address current knowledge gaps, we exposed two tire and one artificial turf samples to outdoor and accelerated artificial photoaging, in dry and wet conditions over 12 weeks. Extracts underwent targeted quantitation, suspect, and nontarget screening via liquid chromatography-mass spectrometry followed by temporal trend analysis and molecular networking. Results indicate that accelerated photoagi
