The point has been debated for years, but a new study has added another dimension to the discussion. A recent study in the <a href="https://doi.org/10.1073/pnas.2300582121">Proceedings of the National Academy of Sciences</a> has created a bit of a panic with the suggestion that high levels of microplastics can be found in bottled water.

Concern had been raised because BPA was known to have hormone-like activity, placing it in the category of “endocrine disruptors.” Hormones are the body’s chemical messengers and are active in very small doses. Our pituitary gland, for example, produces only about 1 microgram of hormones a day, a very, very, small amount, yet it is critical to life.

This wasn’t some experiment by restaurateurs looking to add more snails to the menu. There wouldn’t be much point, since these were New Zealand mud snails, less than half a centimetre in size, with not much meat on them. But the snails are pretty meaty when it comes to research about endocrine-disrupting chemicals. Mon, 30 Sep 2013 01:52:50 +0000 Joe Schwarcz PhD 2016 at /oss
