Bisphenol a officially declared toxic by Canada

Canada became the first country in the world to declare bisphenol A (BPA) to be a toxic substance that poses risks to human health and the environment.

The announcement by the Canadian Health and Environment Ministries confirmed the chemical had formally been added Schedule 1 of the Canadian Environmental Protection Act, 1999 (CEPA 1999).

BPA is an industrial chemical used to make a hard, clear plastic such as re-usable polycarbonate baby bottles. It is also used in the manufacture of epoxy resins, which act as a protective lining on the inside of metal-based food and beverage cans.

In the order adding BPA to the toxic register, Health Canada identified dietary intake as the primary source of human exposure. It underlined concerns regarding the link between the chemical and neurodevelopmental and behavioural effects in rodents and said it was “considered appropriate to apply a precautionary approach when characterizing risk to human health”.

“Therefore, it was concluded that bisphenol A should be considered as a substance that may be entering the environment in a quantity or concentration or under conditions that constitute or may constitute a danger in Canada to human life or health,” said the government order.

Canadian Government said its actions had been based on “robust and relevant scientific evidence”. It noted that Health Canada had considered both studies that were based on guidelines for good laboratory practice and those that were not because “they were considered relevant to risk characterization”.

"Our science indicated that Bisphenol A may be harmful to both human health and the environment and we were the first country to take bold action in the interest of Canadians,” said Leona Aglukkaq, Minister of Health.
