A top brand of baby bottle leached more than double the amount of a hormone-disrupting chemical linked to breast and prostate cancer than a cheaper house brand, new Health Canada tests show.
It found that the concentration level of BPA, an estrogen-mimicking chemical, in the water in the Philips Avent's top-selling baby bottle, Avent Naturally, was 516 parts per billion (ppb).
"It's baby stuff," the Ottawa mother said. "Even if there's the slightest chance, do you think anyone in their ri

Scientists have noticed some disturbing changes in the water, and the reproductive organs of fish, in the St. Lawrence River near Montreal.
Concentrations of estrogen as high as 90 times the normal rate have been discovered just downstream from the island of Montreal, according to researchers from l'Université de Montreal.
"What we measured is about 100 times more than the level known to have significant endocrine-disrupting effects," said Sébastien Sauvé, a professor of environmental chemistry at the university.
Polar and nonpolar fractions prepared from an organic extract of inhalable air particulate material collected from an urban location in downtown Toronto, Ontario, Canada, were examined for estrogen and Ah receptor-mediated activities using in vitro gene expression assays.

A separate Health Canada study of undisclosed brands also found a similar range when researchers filled bottles with boiling water and let them sit at room temperature; the concentration levels of the hormone disrupter in the water ranged from 1.7 ppb to 4.1 ppb.
