Plastic Chemical BPA Declared Toxic In Canada 168

Julie188 writes "The Canadian government has formally declared bisphenol A (BPA), a chemical widely used to create clear, hard plastics, as well as food can liners, to be a toxic substance. Does this mean that you'll be tackled by the Canadian Mounties if you stroll around with some bottled water? Not exactly. Being a toxic chemical doesn't mean you can't get a little love. The government will at first try and set limits on how much BPA can be released into the air or water by factories that use the compound."

    So, our wonderful government declares BPA toxic, while at the same time continuing to deny asbestos's toxicity and exporting asbestos to the rest of the world.

    It's all domestic politics. Banning asbestos would annoy Quebec, the major producer...

      I had gathered that asbestos is perfectly safe and fine as long as it stays out of your lungs; it's a physical contaminant, not a chemical one. (Am I wrong?) BPA contamination has the potential to be much more insidious.

        Everything not a singular element is a chemical compound of some sort or another.

        • The point is that it's not something that's going to interact with your lungs in a chemical way. It's going to have the same exact effect as any other fine particulate substance when airborne.

            Not exactly. Asbestos particles, when inhaled chronically, lead to mesothelioma. Mesothelioma is not lung cancer; it is a cancer of the pleura which cover the lungs. Asbestos particles, because of their form and other characteristics are especially capable of piercing the alveoli and reaching the pleura. Asbestos particles are only 3,000-20,000 nm long, and only 10 nm in diameter (a human hair is 17,000-180,000 nm in diameter; a red blood cell is 8,000 nm in diameter). Only rarely does exposure to any other substance lead to mesothelioma. Smoking, and exposure to other types of particulates, preponderantly leads to forms of lung cancer rather than mesothelioma.

            • That really doesn't make it a toxin. That's a physical characteristic, doing physical damage to the lung.

              You're right that those physical characteristics are somewhat unique, and thus cause somewhat unique symptoms, but that doesn't make asbestos a toxin. It's not some chemical, like BPA, that interacts on a molecular level, where that chemical interaction causes cancer.

              • by fnj ( 64210 )

                Absolutely. We should all be clear that the tissue insult is physical, not chemical.

              • Exactly. It'd be a little like declaring a sharp knife to be a "toxin". A sharp knife can be very dangerous to your body's tissues, since it can easily slice you open, but it's not a toxin, just a physical object that happens to have a sharp edge.

                  Whatever the mechanism by which asbestos damages your lungs, this is the real hypocrisy: Asbestos is strictly regulated in Canada, but Canada exports the stuff for use in countries with lax or no regulation.

                  • Is that hypocrisy? Canada can't control the laws in other countries, and asbestos still has many valid uses, as long as it's handled properly. Nitroglycerin is dangerous too, but handled properly is very useful. Is someone a "hypocrite" for exporting explosives to countries with lax regulation for use in demolitions?

                    If Canada refused to export to countries without strict regulation, how well do you think that's going to go over diplomatically? That's basically insulting the purchasing country.

      The problem with asbestos is not the material itself. It was how it was used and the conditions in which it was produced. The ban and fear of asbestos was purely emotional and political.

          So instead of properly identifying the risk of a product and for which applications it is suited or not, we should totally ban it because illegal alien construction workers may be put in arms way due to the use of the product over 3 decades ago? Amazing logic.

          This is exactly the kind of logic, thoughts and statement we should keep out of product regulation processes.

    This is definitely a step in the right direction. BPA is a risk to the entire population and it's use is very widespread. It disrupts our hormonal system and has now been linked to different types of breast cancer, heart disease and endocrine disorders. It also affects our reproductive systems. People really need to be aware that the use of plastics containing BPA is harmful and that use of this substance is currently ubiquitous throughout the world.
    • Oddly enough Thermal Receipts have the most BPA. Something like a 1000 x as much as you would get from a water bottle.

      If you get a receipt and then eat your burger is the receipt a food product regulated in the same way you might regulate a plastic fork?

      In Canada regulation will all depend on if the receipt paper is made in Quebec or near Ottawa.

    • It also affects our reproductive systems. People really need to be aware that the use of plastics containing BPA is harmful and that use of this substance is currently ubiquitous throughout the world.

      Given that our world is overpopulated, and the population is growing rapidly, would it really be such a bad thing if our reproductive systems were dampened a little? And I actually am not trying to be funny here. I'm somewhat half serious. Would mankind be better off if we started having fewer babies?

      • Not this way. The parent said BPA "has now been linked to different types of breast cancer, heart disease and endocrine disorders." Any benefit you might get from slowing reproduction down a little will be much more than made up for by these other health problems.

        If you want to find some insidious chemical to limit reproduction, find something that doesn't hurt peoples' health in other ways. We need a population that is stable, yet healthy. We spend way too much on healthcare as it is, as a society.

      • We already do have fewer babies. Birthrates in almost all of the western world (Europe, Canada, and the US) are below replacement rate. The only reason the above countries are experiencing population growth is immigration. Some countries, such as Germany, Japan, and Russia, are currently experiencing negative population growth.

      • Even if a few venues of baby production shut down supply and demand will kick in and the market will move to fill the void. I doubt that the total number of babies produced each year will really drop. They will just take more to get. Though that could result in easier governmental caps or controls. If the number of suppliers is lessened.
    • I just hope that there's a decent alternative to it. Lead-free solder didn't work out quite like the leaded stuff. However, from what I understand (and I may be wrong), BPA is only released from plastics when heated past a certain point. As such, a water bottle isn't going to hurt you unless you leave it baking in your car all day. Dishwashers are probably fine as they're rinsing the things out when the bottles are heated, so you'd have very little BPA left when it was done. I think the big concern was baby

      I'm pretty certain they'll come out with a BPA-free plastic version instead, since that's all the rage in bottles and food containers for infants.

      Personally, I'd be happy to have a world free of BPA. Unfortunately, that's going to be very difficult as it's found in many common items. For some, there are plastics that are good alternatives, but others, it will be some time before alternates can be found. In particular, epoxy binders used wood-based sheet goods production (particle board, chip board, flooring, etc.) are bad and are going to be around for a long time since there is so much of it installed.

      My family and I have stopped eating anything that comes in a can. Not only are cans typically lined with BPA-bearing plastics, but the contents are in intimate contact for a very long time. Avoiding canned foods has been pretty easy with one exception: canned tomatoes. If anyone has a good solution for those, I'd love to hear it.

Chemical bans really need to be doing cost benefit analysis, tax rather than ban to automate the process. If we get rid of BPA in all the low hanging fruit we'll have gotten rid of 99% of the BPA we come into contact with. The last 1% will likely cost 5x as much to get rid of as the first 99%, there is no point in doing so. Perhaps a hard ban in food packaging and children's toys.
