Don’t drink the (warm) bottled water, study says...

Americans can take a warning from a University of Florida study of bottled water in China ─ don’t drink the liquid if you’ve left it somewhere warm for a long time.

Plastic water bottles are made from polyethylene terephthalate. When heated, the material releases the chemicals antimony and bisphenol A, commonly called BPA.

While the U.S. Food and Drug Administration has said BPA is not a major concern at low levels found in beverage containers, it continues to study the chemical’s impacts. Some health officials, including those at the Mayo Clinic, say the chemical can cause negative effects on children’s health.

And antimony is considered a carcinogen by the International Agency for Research on Cancer, part of the World Health Organization.

UF soil and water science professor Lena Ma led a research team that studied chemicals released in 16 brands of bottled water kept at 158 degrees Fahrenheit for four weeks, what researchers deemed a “worst-case scenario” for human consumption.

Of the 16 brands, only one exceeded the EPA standard for antimony and BPA. Based on the study, storage at warm temperatures would seem to not be a big problem, Ma said. But she said more research is needed to know if other brands are safe. Full story...
