部分加拿大零售業者已經將該產品下架。衛生部長克萊門( Tony Clement )與環境部長貝爾德( John Baird )宣布將自4月26日起，舉行為期60天的討論，來徵詢多方意見。
The Canadian government is asking for public comment on whether or not to ban the import, sale and advertising of polycarbonate baby bottles than contain the chemical bisphenol A. The chemical has been shown to leach from some plastics, harming human health by disrupting normal hormone and neurological function and altering gene activity.
Some Canadian retailers have already pulled bottles made with the substance off store shelves. Health Minister Tony Clement and Environment Minister John Baird announced the action Friday and the 60 day public comment period began on Saturday.
"Canada has been the first country in the world to conduct risk assessments on a number of chemicals of concern, as a result of a new initiative announced by the Prime Minister on December 8, 2006 known as the Chemicals Management Plan," said Clement.
Health Canada's screening assessment of bisphenol A primarily focused on its impacts on newborns and infants up to 18 months of age; however, health risks for Canadians of all ages were considered in the screening.
It was determined that the main source of exposure for newborns and infants is through the use of polycarbonate baby bottles when they are exposed to high temperatures and the migration of bisphenol A from cans into infant formula.
The scientists concluded in this assessment that bisphenol A exposure to newborns and infants is below levels that may pose a risk, however, the gap between exposure and effect is not large enough.
The government proposes to work with industry to develop alternative food packaging and develop a code of practice and to list bisphenol A under Schedule 1 of the Canadian Environmental Protection Act.
Environment Canada scientists found that at low levels, bisphenol A can harm fish and aquatic organisms over time. Studies indicate that it can currently be found in wastewater and sludge treatment plants.
The top Canadian Green Party official says bisphenol A is found not only in polycarbonate plastic baby bottles and in the lining of canned foods and beverages but also in childrens?toys, baby bottles, dental sealants, sports helmets, compact discs and other materials made from hard plastics.
Green Party leader Elizabeth May said that nonylphenol, another hazardous substance with similar hormone-disrupting properties should be given the same attention as bisphenol A. Nonlyphenol can also be found in plastics, as well as personal care products, commercial and household cleaners and some manufacturing processes. Nonylphenol and its derivatives have already been banned in the European Union due to concerns over both human health and its effect on aquatic life after entering waterways
