A little bit of poison?

Expert witnesses fail to acquit BPA in the court of public opinion

Last month, Canada became the first – and still the only – country to formally declare bisphenol A (BPA) a toxin, listing the organic compound as hazardous both to human health and to the environment.

BPA is an endocrine disruptor that can mimic the effects of estrogen. In vivo studies have linked even very low concentrations with permanent changes to the brains and reproductive systems of laboratory animals.

Two years ago, Canada announced its intention to ban BPA from baby bottles, as did several US states. In the event, they were largely pre-empted by the industry, as the shower of negative publicity surrounding BPA made it commercially nonviable.

But BPA hardly went away. In fact, it’s ubiquitous. It may be found in cellphone casings, cash register receipts, and all sorts of packaging, including and especially canned food. It’s an extremely common ingredient in the epoxy linings that cover the metal on the can’s inside.

This, most experts agree, is the number one source of human exposure. In Canada, the age group with the highest detected levels of BPA is teenagers, followed by younger kids. These are also the age groups most likely to eat canned foods.

This month, a panel of international experts sat down in Ottawa to get to the bottom of the issue of BPA in food. The meeting was sponsored by the World Health Organization, with support from the FDA, Health Canada and the European Food Safety Authority.

Their conclusion? That canned food is indeed the main avenue by which we absorb BPA … and it’s not a problem. Their modeling shows that BPA coming in through food consumption matches the quantity going out through urine. BPA does not significantly accumulate in the body, says WHO, and therefore action to remove it from food packaging would be “premature”.

Why premature? Because, as WHO acknowledges, there are still several studies suggesting adverse health effects even at very low levels, and finding worse overall health in people who work around BPA, for instance in canneries. Some of the best quality studies have still to report their findings, so the WHO wants to keep its options open.

But WHO also didn’t want to hurt industry by causing a public health scare before it knew the facts, so it held the meeting behind closed doors and made participants sign confidentiality agreements.

This approach may have backfired. Several manufacturers, apparently unable to stand the strain of not knowing, pre-empted the conference’s findings by announcing plans to remove BPA from their products while the experts were still deliberating. Among these was the world’s largest, Nestlé.

But Nestlé only said it would remove BPA from its US products – though many such products will undoubtedly find their way onto Canadian shelves. Different solutions might apply in different parts of the world, said the company, depending partly on local “cultural sensitivities” and consumer preferences. In other words, where the public shows no sign of caring about potential toxicity, manufacturers are unlikely to worry about it either.

    What do you do when such a large proportion of the society is locked into " concrete operational thinking"?
    What is the thing preventing the physiologic adjustments in the pre-frontal cortex?

    Is it cultural?
    Is it environmental?
    Is it genetic?

    Regardless of it's origin it results in a preponderance of ?thinkers who are stalled around age 14.
    In the midst of their intellectual accomplishments ( which are not hindered) their emotional limitations keep them believing " nothing can happen to me".
    Added to this is the "angst" never leaves them ... and the " sense of other" never gets a foothold in their fragmented personalities.

    Do you really think we can overcome what you observed:

    'In other words, where the public shows no sign of caring about potential toxicity, manufacturers are unlikely to worry about it either '

  7. George M. Enei, the director general of science and risk assessment at Environment Canada, one of two government departments that made the designation, said the move would make it easier to ban the use of BPA in specific products through regulations rather than by amending legislation, a cumbersome and slow process.But he said the government’s first step would probably be to set limits on how much BPA can be released into the air or water by factories that use the compound.

  9. Ulaşım en az iletişim kadar insan hayatında önem arz etmektedir.Amaca göre toplumdaki bireyler hava,deniz,kara ve ya demir yolu bağlantılarını
    kullanmaktadırlar.Ancak söz konusu evden eve nakliyat olunca ulaşım yollarında seçim yapmak daha önemli hale gelmektedir.Örneğin evini İzmir'den İstanbul'a taşıyan
    bir aile,öncelikle nakliye edilen ev eşyalarının gidilecek noktaya en az zarala ulaşmasının sağlanmasıdır. Yani gidilecek araç ve gereçlerin sigortalanmasıdır.
    Bir diğeri ulaşım bedelinin aile bütçesine uygun olmasıdır.Bunun yanı sıra,ulaşım esnasında çıkabilecek herhangi bir koplikasyonda, nakliyat sahibinin
    iş bitiminin garantisini müşteriye veriyor olması ve oluşan problemin maddi_manevi sorumluluğunu taşımasıda önemli bir husustur.
