People have the habit to store bottled water in their vehicles, especially during the summer. The majority of people choose to drink water from plastic bottles instead from glass or stainless steel, which is a big problem.
Drivers often drink water from plastic bottles who have been in their car for who knows how long.
The Centres of Disease Control and Prevention state that when the temperatures outside range from 80 degrees to 100 degrees, the temperature inside a car parked in direct sunlight can quickly climb to between 130 to 172. The upper scale on this range is higher than the “low” temperature setting on most conventional ovens.
According to a study from the American Academy of Pediatrics, car’s interior temperature can rise approimately 40 degrees within one hour, even when the exterior temperature is only 72F.
Bottled water in this kind of circumstances, can contain microbes at levels capable of making a person’s immune system sick, within a week. This kind of bacteria may come from the water source, or from the bottle and the worst part is that can be multiplied with modest heat. But microbes are just one problem, plastic is another.
Plastic Still A Serious Problem In Bottled Water
A study conducted at the University of Florida looked at 16 brands of bottled water and revealed that all the bottles contain bisphenol A or BPA levels in them.
BPA is a dangerous chemical that is assosiated with many health problems such as digestive problems and issues with brain development. Not only is present in plastic bottles, but in arount 2 billion products in the United States as well, and they are used by people every day. Children and pregnant women must avoid contact with BPA at any cost, because it is very harmful for body and brain development.
There are some simple ways to avoid BPA, but the governements are not proactive about releasing that information to the public.
Eventhough the current levels in the plastic are safe, according to the researches, they become harmful after a four-week period when left in 158-degree heat. Due to its reactivity to heat, FDA has warned not to keep hot or boiling liquids in plastic containers.
Polyethylene terephthalate is used to make plastic water bottles, but it is also used in many food and drink packaging because it is shatterproof, durable and lightweight. Bad news is that when heated, it releases the chemical BPA, which affects hormone levels by mimicing estrogen, and may trigger health risks if exposed at high levels. While the initial levels of BPA found in the 16 brands–save for one–did not exceed EPA standards for these chemicals, scientists are more concerned about how the chemicals increased over time.
Eventhough some manufacturers claim that they have substituted the BPA with much safer alternatives, it is still unclear if the BPA-free products were using compounds similar to BPA, such as bisphenol-S, which has been shown to exhibit similar health impact to BPA.
Lena Ma, the study leader said in a press release: “If you store water long enough, there may be a concern,”
We should warn people that reusing plastic bottles is not safe, especially if they are not cleaned and dried properly. People can get sick from the accumulated pathogens which can cause vomiting or diarrhea. This is true with other types of containers, not just disposable water bottles.
Keep in mind not to drink the water that has been in your car for longer period, just throw it out and switch to glass or stainless steel.
