Bisphenol A is used in the manufacture of polycarbonate plastic products – in particular baby bottles, sippy cups and the blue bottles used on water coolers. Tests have shown that BPA leaches into the contents of these containers in small amounts. Canada is in the process of banning the use of polycarbonate in baby bottles and products associated with children. The most at risk are unborn and newborn children.
BPA has been linked with causing:
- An increased risk in breast cancer
- An increase risk in prostate cancer
- Onset of early puberty in girls
- Increased risk of miscarriage
- Decreased sperm production
Products marked with a recycle number 7 on the base and PCA are made from polycarbonate.
Phthalates are plasticisers primarily used in the manufacture of PVC products but can also be found in other products such as fragrances. Evidence has been building in recent years linking them with adverse health effects such as reduced fertility in males, developmental problems and respiratory impairment. Products with the recycle number 3 on the base are the most likely users of phthalates.
Nova spring water products do not contain any BPA or phthalates.
