The Importance of Vehicle Indoor Air Quality

The Importance of Vehicle Indoor Air Quality

Posted 8 months ago

The coveted “new car smell” is now known to result from chemicals emitted from plastic and leather parts that make up the interior of automobiles. These parts emit volatile organic compounds (VOCs; e.g., benzene, formaldehyde), semi-volatile organic compounds (SVOCs; e.g., phthalates, trichlorophenyl phosphate [TCPP]), and other chemicals. For example, TCPP is a flame retardant often found in polyurethane foams. Although TCPP provides safety by reducing the risk of these foams igniting in a fire or accident, its semi-volatile nature causes it to release into the car’s interior, where passengers can be exposed to its vapor.
