What Happens With a Bottle of Water That is Left Out in the Sun?
According to a recent study at the University of Florida, drinking warm water from plastic bottles can be carcinogenic.
Scientists have discovered that bottles made from polyethylene terephthalate, known as PET bottles, can cause health issues. If these are stored in a warm environment harmful chemicals such as antimony and bisphenol A, commonly known as BPA, are released.
While the American Food and Drug Administration says that low quantities of BPA are not harmful, scientists continue to study the effects of these chemicals. The Mayo cancer center in Minnesota is convinced that warmed bottles have a negative effect on the health of children. The International Agency for Research on Cancer confirms this and adds that warmed bottles release carcinogens. Lena Ma, the lead researcher of this study, also agrees. ‘If the water is stored long enough in a warm area it may cause problems’, she said in a statement.
The researcher based that conclusion on the results of an extreme experiment where a worst-case scenario for man was simulated. She kept sixteen bottles of water from various Chinese brands for four weeks in 70 degrees room. And guess what: after the test period both the antimony level and the BPA content had increased.
This could cause the health issues in China to increase. The quality of the Chinese tap water is extremely bad, which means that citizens sometimes keep bottles of water in their (warm) vehicle for weeks on end. According to the latest Chinese statistics, just in 2001 9.6 billion liters of water was sold. Ma emphasized that other beverages that are packaged in polyethylene terephthalate should also be checked because the results, in the worst case, may be even more disturbing.20-10-2014
