An NIEHS-funded study shows that prenatal exposure to butylbenzyl phthalate (BBzP) can increase a child’s risk for developing eczema. BBzP is found in vinyl flooring, artificial leather, and other materials, which can slowly release it into indoor air.
The study included 407 nonsmoking African-American and Dominican women and their children living in New York City. A urine test during the third trimester of pregnancy assessed BBzP exposure.
The researchers found that onset of eczema by age 2 was 52 percent more likely in children whose mothers were exposed to higher concentrations of BBzP, compared to those whose mothers were exposed to lower concentrations. The African-American mothers were twice as likely as the Dominican-American mothers to report that their child was diagnosed with eczema. However, both groups showed a similar association between BBzP exposure and eczema. The researchers examined allergies as a possible mechanism, but found no evidence of a link between BBzP exposure and allergy.
