Here's a better idea, why don't we start banning plastics for anything food related.

Along these lines I'm sure we will learn that all the artificial sweeteners we have replaced sugar with are probably harming our bodies in ways we didn't initially foresee too. School and gym class hasn't really changed, we had video games too, and children dieting was almost unheard of. Now childhood obesity has exploded in a generation and you see overweight children drinking diet sodas. At least in the US the obesity epidemic coincides with 2 important trends in the food industry: The move away form sugar towards other sugar substitutes and the move towards "fat free" products that offset that change by adding more sweetener (ie sugar and sugar substitutes). Just like DDT, the tobacco industry, and leaded gasoline I'm sure a lot of things we do and use today we will look back on in the future as harmful.

So, how did the scientists introduce the BPA/BPS to the fish? I’m my untrained reasoning, it would only be a valid demonstration if the fish were allowed to swim/live in a bowl or container made of that material for a period of time. I imagine the scientists used some pure form of the substance to contaminate the fish environment to push their theories. No mention in the article about their process.

I think you will find with some research that no PET bottled water product ever used bisphenol A, S or any other letter. Why then, do articles like this keep showing water bottle products. Not that I am a big fan of them, but it is dis-information. Polycarbonate bottles and carriers for infant formula bags did use PBA, but that has been abandoned as has food can lining polymers. Carefully research what you are promoting.

@verdico Of course that would be the way to go. Unfortunetly it would require some sort of intelligence at work.

Daishy: And in each case, including Asbestos, Fluoride, DDT, tobacco, and a myriad of other things, they have ALWAYS KNOWN from the beginning they were TOXIC!

First of all, this is a narrowly defined study of electrical signals in response to danger stimuli in the brains of goldfish. It can't reasonably be extrapolated to indicate overall "health" of neurons in the brain in fish, let alone humans. In this study BPA and BPS appeared to increase the efficiency of the acoustic stimulus while decreasing the optical stimulus of the neuron.

Secondly, it used concentrations of BPA and BPS far greater than environmental concentrations, anywhere from hundreds of times higher to 100,000 times higher, but the study claims that the "lower" amount (10 µg/l) is an "environmentally relevant concentration". Yeah, if you're a fish in a vat of BPA solution at a plastics plant.

Lastly, no properly controlled studies have found BPA causes harm in animals or humans at doses that they would be exposed to in the environment. Most international regulatory agencies have concluded that non-occupational BPA exposures do not pose a credible risk to humans. The only studies that show potential problems used very high doses (like this one) or failed to compare the incidence of biological issues with the ones in the control group, suggesting that they were within the range of normal biological variation.

Some people can be so cavalier about what goes into one’s body, even if we are not exposed to dangerously high doses does not mean a little is harmless. Too much is unknown about long term exposure and scale of damage to small dosage. It’s better to err on the safe side and ban all form of plastics from food packaging. It has also been a bane to the environment as well. Humans lived without them for most of civilisations, there is no need to becoming a lazy throwaway society.

@1stClassOPP Read the journal article - no imagination needed. BPA/BPS was introduced to the water the fish lived in. Having the fish live in a tank made from plasticised material would have been an uncontrolled experiment.

@aksdad 10 ug/L is definitely possible, in Europe and North America as well as Asia. In fact 100 ug/L is possible. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4674187/
