The number in parentheses beside the drainage region name represents the identifier number of the drainage region. The Federal Environmental Quality Guideline in sediment for Bisphenol A is 25 nanograms per gram (ng/g) of dry weight. Samples with BPA concentrations above the guideline are defined as an exceedance. See the drainage region map (www.canada.ca/en/environment-climate-change/services/environmental-indicators/bisphenol-a-water-sediment.html#map). Measurements were made in 272 surface sediment samples collected in 31 sites from 9 drainage regions between 2011 and 2018.,,,,, Source: Environment and Climate Change Canada (2019) Chemical Management Plan Monitoring and Surveillance (www.canada.ca/en/health-canada/services/chemical-substances/chemicals-management-plan/monitoring-surveillance.html).,,,,, Available on the Environmental indicators website (www.canada.ca/environmental-indicators).,,,,,
