Mr. Speaker, Bill C-307, the Phthalate Control Act, essentially seeks to better control, if not to forbid, the use of phthalates in a wide range of commonly used objects because those substances represent a risk to the health of Quebeckers and Canadians.
The initial text of the bill obliged the Minister of the Environment to make regulations prohibiting the use of three types of phthalates. The prohibition applies first to BBP, which is found in many products for use by a child in learning or play, and products that are put in the mouth of an infant when used. The second product the bill seeks to prohibit is DBP, which is quite often found in cosmetics as well as in the products mentioned previously that are put in the mouth of a child or infant when used. The third product this bill seeks to prohibit is DEHP, which is also found in cosmetics, but especially in medical devices. However, the bill excludes blood bags from this prohibition.
Furthermore, the purpose of the bill is to amend Schedule 1 of the Canadian Environmental Protection Act, to include the three aforementioned products, BBP, DBP and DEHP, on the list of toxic substances.
Phthalates are part of a family of chemical products mainly intended for industrial use. Phthalates are found in a number of common consumer products such as adhesives, vinyl flooring, lubricating oils, capacitors, detergents, solvents, pharmaceutical products, electrical wires and cables and cosmetic products such as perfume, deodorant, shaving lotion, shampoo, hair spray and nail polish.
The use of phthalates as softening agents is another common application for these products. Most PVC-based—that is, polyvinyl chloride—rigid, semi-rigid and flexible articles also contain phthalates.
The proportion of phthalates can be as high as 50% in some products, for example, plastic bags, window frames, food wrap, raincoats, shower curtains, rubber boots, garden hoses, bath toys and medical devices.
The toxicity level of phthalates varies depending on the kind of compound. DEHP phthalates have a higher toxicity potential than the other two. The main effects of phthalates reported in experiments conducted on various animal species are testicular atrophy, decreased fertility and a lower fetal weight. Some researchers also believe that phthalates can be carcinogenic.
According to a report by the Institut national de santé publique du Québec, experts have concluded that BBP has little or no effect on reproduction and development. However, for DEHP and, to a lesser degree, DBP, the results arouse more concern. The use of various medical devices that contain DEHP raises some concern about the effects on the development of premature male babies who need intensive and prolonged care.
Let us now talk about the precautionary principle. This principle was officially recognized and confirmed by the international community in the Convention on Biological Diversity adopted at Rio in 1992, a convention that was ratified by Canada.
According to this principle, when there are sufficient grounds to believe that an activity or product could cause serious and irreversible damage to health or the environment, mitigation measures must be taken until the effects can be documented. Such measures may reduce or put an end to certain activities or ban certain products.
In Canada, these phthalates are no longer present in toys or objects that could be put in a child's mouth. In 1998, following a study of the risks associated with objects intended for children, Health Canada concluded that the amount of phthalates found in flexible PVC products could pose a risk to the health and safety of children. Manufacturers, importers, distributors and retailers have since been obliged to ensure that flexible plastic soothers and rattles are free of DEHP.
As to DEHP in some products designed for use in children's education, we think the precautionary principle demands that they be banned.
With respect to DEHP and phthalates in medical devices, we must protect at-risk groups by doing everything in our power to promote the use of alternative DEHP-free products. Nevertheless, until such phthalate-free medical devices are on the market, Quebec's public health institute does not recommend restricting access to certain treatments or procedures, because the health benefits outweigh the dangers associated with DEHP exposure. Until suitable substitutes become more readily available, we believe that it may be risky to ban DEHP in all medical devices, excluding blood bags.
I would now like to discuss phthalates in cosmetics. DEHP and DBP are present in perfume, deodorant, after-shave lotion, shampoo, aerosol sprays and nail polish.
Many environmental groups and consumer associations have strongly denounced the use of phthalates in cosmetics. According to Health Canada, DBP in cosmetics presents no health risks in concentrations of less than 10%. In 2004, Health Canada announced its intention to amend cosmetics regulations in order to require cosmetics manufacturers and distributors to list the ingredients on the product label. According to our investigation, this change, which would have at least informed the consumer, never went into effect.
To summarize, the Bloc Québécois is in favour of Bill C-307. There has not been enough research to date on the effects of phthalates on human health. While awaiting more precise answers regarding the health risks associated with phthalates, the government should limit as much as possible the exposure of vulnerable populations to various chemical compounds, as a precautionary measure.
We note that some of the bans proposed in the original bill have been amended, since they went too far, given that reliable, effective and safe replacement products were unavailable for certain medical devices.
It has always been clear to the Bloc Québécois that implementation of the bill tabled by the member for Skeena—Bulkley Valley should not give rise to more health problems than it solves.
The Bloc Québécois position is supported by the Institut de santé publique du Québec, which stated in a 2004 report that until medical devices without phthalates are on the market, it is not recommended or even warranted to deprive the public of some types of treatments or procedures that can be beneficial to health and whose outcome outweighs the dangers of exposure to DEHP.
The Bloc Québécois believes that Bill C-307 responds to the concerns of the Institut de santé publique du Québec with respect to medical equipment and that it provides protection as well as fulfilling a need. We will support it.
