On April 17, 2013 Health Canada released a second set of biomonitoring data from 2009-2011, which includes children from 3 to 5 and shows bisphenol A (BPA) to be present in 95% of urine samples from Canadians aged 3 to 79. The BPA levels did not change from the previous biomonitoring cycle 1 (2007-2009). Then the geometric mean was 1.33ug/L urine for Canadians aged 6 to 79.
The Report on Human Biomonitoring of Environmental Chemicals by Health Canada monitors the levels of 86 environmental chemicals in Canadians, including phthalates, bisphenol A, triclosan and antimony. The first cycle was published in 2010 and another began in 2012 and will be completed in 2013.
