Not So Sweet Dreams

We are all well aware of the constant presence of chemical compounds in our surroundings. Because of their prevalence, it can be a natural reaction to trust in their safety; anything so common shouldn’t be a threat. A team of environmental engineers from Cockrell School of Engineering has recently investigated a frightening topic that had never previously been considered. Looking at the foam padding in new crib mattresses, the team recorded high levels of volatile organic compounds (VOCs) emitted from the material. Sometimes found in products like household cleaners and sprays, VOCs include chemicals like formaldehyde, benzene, and acetone, among others. No conclusive studies have shown the definitive health effects of exposure to the chemicals, although they are regarded as dangerous chemicals.

By comparing polyurethane foam and polyester foam in a group of both new and old crib mattresses from ten different manufacturers, the researchers found that the new crib mattresses release VOCs at a level four times higher than old crib mattresses, and a baby’s body heat triggers VOCs to be emitted. Frighteningly, the VOC emission levels were found to peak in the baby’s immediate breathing zone. The VOC levels that the new crib mattresses emit are comparable to some other potentially hazardous household materials, including laminate flooring and wall coverings.

Considering that infants are highly susceptible to pollutants and that infants can spend over half of their time asleep in their cribs, the presence of these chemicals within the mattress material is shocking. The findings did not shock some of the experts, saying that the levels of VOCs, while surprising, were not high enough to cause true alarm for the safety of children. However, those experts deem this very valuable research and worthy of further investigation to assure safety. 

It is not recommended to replace new mattresses with older mattresses that contain banned substances, like flame-retardants; reusing an older crib mattress that is known to have no banned substances may reduce infants’ exposure. To reduce levels of VOCs in new mattresses, a period of airing-out may help. Keep an eye on this issue to make sure your children are protected.
