AUSTIN, Texas — In a first-of-its-kind study, a team of environmental engineers from the Cockrell School of Engineering at The University of Texas at Austin found that infants are exposed to high levels of chemical emissions from crib mattresses while they sleep.
Analyzing the foam padding in crib mattresses, the team found that the mattresses release significant amounts of volatile organic compounds (VOCs), potentially harmful chemicals also found in household items such as cleaners and scented sprays.
The researchers studied samples of polyurethane foam and polyester foam padding from 20 new and old crib mattresses. Graduate student Brandon Boor, in the Cockrell School’s Department of Civil, Architectural and Environmental Engineering, conducted the study under the supervision of assistant professor Ying Xu and associate professor Atila Novoselac. Boor also worked with senior researcher Helena Järnström from the VTT Technical Research Centre of Finland. They reported their findings in the February issue of Environmental Science & Technology.
The researchers found:
- New crib mattresses release about four times as many VOCs as old crib mattresses.
- Body heat increases emissions.
- Chemical emissions are strongest in the sleeping infant’s immediate breathing zone.
