"To date, studies have failed to find an association between BBP and breast cancer," Borak said. "This study doesn't add specific information on breast cancer and environmental interactions."
Efforts to reach the American Chemistry Council, a chemical industry group, for comment on the study were unsuccessful.
In October, California adopted a law that will ban trace amounts of BBP in toys and baby products such as teething rings, according to published reports.
And in March, a study published in the journal Environmental Health Perspectives suggested that exposure to phthalates could be fueling the obesity epidemic by contributing to abdominal obesity and insulin resistance in men.
