Study warns about warm water in plastic bottles
Now may be a good time to throw away all of the half-filled water bottles sitting in your car. According to a new University of Florida study, plastic water bottles that have been sitting out in the heat may release the known carcinogens antimony and bisphenol A (BPA) into the water.
The research team analyzed chemicals released in 16 brands of bottled water kept at 158 degrees Fahrenheit for four weeks. They found that as the bottles of water warmed over that period, antimony and BPA levels increased. Of the 16 brands, only one exceeded the EPA standard for antimony and BPA, however.
While the U.S. Food and Drug Administration has said BPA is not a major concern at low levels found in beverage bottles, some health officials, including those at the Mayo Clinic, say the chemical can cause negative effects on children’s health.
The researchers acknowledged that more research is needed, but suggested that people might want to avoid leaving bottled water in a hot garage for weeks on end or drinking water left in your car all day during the summer.
