Hot mineral water bottle water
Why should not you drink hot bottled mineral water?
A few years ago, there were rumors that American singer Cheryl Crowe claimed that drinking bottled water in her car caused her to develop breast cancer. Since then, there have been concerns about plastic bottles releasing hazardous substances into our water.
Scientists from Nanjing University in China and the University of Florida studied the effect of water retention on 16 brands of water bottles in China. This rabid experiment was performed according to the standards at three temperatures:
39 degrees Fahrenheit (3.9 degrees Celsius), refrigerated water temperature 77 degrees Fahrenheit (25 degrees Celsius), standard room temperature 158 degrees Fahrenheit (70 degrees Celsius), car temperature
According to a 2009 study, researchers measured the amount of two substances in mineral water bottles – Antimony Antimony and Bisphenol A (BPA) after one, two and four weeks.
Antimony, a small amount of heavy metal, has been found to play a role in lung, heart and gastrointestinal diseases. The International Agency for Research on Cancer has classified antimony trioxide, a form of the metal, as a “potential carcinogen.”
BPA is a chemical that can replace estrogen in the human body and is found in some plastics. The US Food and Drug Administration (FDA) has banned the use of this substance in bottles and cups of children.
The researchers found that with increasing temperature and time, increasingly high levels of antimony were detected in the water bottle. Especially at 77 degrees Fahrenheit, the release of antimony occurred at twice the cooler temperature, although the amount of material released varied in different brands and increased significantly in 6 of the 16 brands surveyed at 77 degrees Fahrenheit. BPA levels rose in only three bottles at this temperature, although the concentration was not so alarming, a senior expert said. But the presence of BPA in plastic water bottles over time is still a mystery. Because theoretically BPA should not be present in plastic composition. The explanation given for this is that if during the production process, especially if you use recycled plastics, if you find a small amount of BPA, this is an impurity.
At 158 degrees Fahrenheit, the hot temperature inside the car, the concentration of antimony increased steadily, this increase was about 319 times the amount of metal compared to the temperature conditions of the refrigerator. However, this amount, which was equivalent to 0.00026 mg, was lower than the normal limit of 0.0006 mg. Of course, in countries like Japan, it is considered more stringent than normal.
Scientists estimate that the worst form of the story is drinking highly contaminated branded bottled water, which could mean consuming 0.0004 mg of antimony per kilogram of body weight per day, which they said could pose a health risk, especially for children. To have.
Another factor to consider is the concentration of calcium, which is commonly found in mineral water bottles and has been shown to increase antimony release. Therefore, the researchers wrote in the article that the health risk of antimony released from polyethylene bottles was underestimated in this study.
However, polyethylene is a very common compound for the production of plastic bottles and food containers, and although this research was conducted in China, antimony was also present in bottles produced in the United States, but its amount is unknown.
However, it is recommended to avoid storing water and consuming it in plastic bottles at high temperatures and consume them at temperatures such as refrigerator temperature or finally room temperature.
This does not mean that plastic bottles are not safe in terms of health, but it is important that the type of storage is important. However, the amount of hazardous substances in them may be lower than normal, but their small amount also raises concerns.
