BPA found in 91 percent of Canadians

Ottawa -- Researchers say 91 percent of Canadians age 6 to 70 have detectable amounts of the controversial chemical bisphenol A in their systems.

The figures were released as part of a study by the Canadian Health Measures Survey in which blood and urine of a representative sample of Canadians was analyzed for indicators of more than 80 environmental contaminants, a Statistics Canada release said Monday.

BPA is an industrial chemical used in the production of polycarbonate plastic and epoxy resins for food containers, water bottles and protective linings for canned food and beverages. It does not occur naturally in the environment.

Some animal studies suggest exposure to BPA very early in life can affect neural development and behavior.

BPA concentrations were measured for the first time at a national level in Canada by the CHMS from 2007 to 2009.

Concentrations of BPA in urine based on volume were higher for children aged 6 to 11 than they were for adults aged 40 to 79, and the highest concentrations were measured in teens age 12 to 19, the study said.
