Some of these chemicals have been associated with health effects. PET bottles may contain chemicals, called non-intentionally added substances, which may get added due to the manufacturing process, which can leach into the water.
It is important to remember that we are exposed to multiple chemical mixtures daily and therefore we have mixture effects. This means that even though these individual chemicals are present in low amounts that should not cause effects, collectively they may exert an effect, which results in an adverse health effect.
It is better to be plastic-wise, make sure you know your numbers [recycling codes - see image above] and read the labels and make sure the bottle is BPA free or invest in a stainless steel or glass bottle. They are not "single-use" bottles, are not trash and are safe to use.
There has been a lot of confusion about what is in our plastic containers since concerns were raised about the safety of polycarbonate products containing BPA. BPA is not used in the production of PET material, nor is it used as a chemical building block for any of the materials used in the manufacture of PET.
PET bottles are safe for use and reuse so long as they are washed properly with detergent and a little water to remove bacteria, as you would any other container. Editor's note: a previous version of this story included an example of the amount of antimony oxide that can safely be consumed.
Researchers from Arizona State University collected nine different brands of bottled water and measured how much of a particular chemical, antimony, the bottles released. Antimony is commonly found in the plastic used to make water bottles. If ingested, it can cause vomiting and diarrhea, but it's not considered a carcinogen. The US Environmental Protection Agency has set the maximum concentration for antimony in drinking water at 6 parts per billion ppb. The researchers found the water in the plastic bottles had only 0.
They also tested the local tap water for comparison and found antimony levels of 0. The study can't say how much antimony might leach into the water after more than three months, but the results suggest that — with reasonable water bottle use — the levels in your water will remain well within what's considered safe.
There have been reports of DEHA, a possible carcinogen , leaching into bottled water, too, but the Natural Resources Defense Council says this is an "urban legend. Bacterial growth, however, is a problem if you're reusing a plastic a water bottle again and again. PET plastic bottles are the most recycled type.
This is done automatically at most recycling centers. You should, however, rinse or wash out your bottles before recycling them. Check with your local recycling center or with your local elected officials to find out the exact recycling specifications required in your area. Avoiding use of bottles with this code may make sense for you and your family, as well as for the planet and our national economy.
The material is called poly diketoenamine , or PDK. It can be broken apart at the molecular level and given life in any new form, including a different texture, color, or shape without compromising its initial quality or performance. This type of material will be easier to sort at recycling centers. If used in a broad-based manner by manufacturers, plastics made from PDK may make plastic waste in landfills and in oceans a thing of the past.
The United Nations estimates around million tons of plastic is manufactured each year. Of that number, more than 8 million tons finds its way into our oceans. There it contaminates coral reefs and kills mammals, fish, and seabirds, who mistake plastics for food. The manufacturing process for all types of plastic requires vast amounts of energy.
Plus, it emits toxins and pollutants into the air, water, and ground water. Plastic bottles litter our streets, marring the national landscape. They choke our landfills, taking centuries to decompose. When you factor in that most plastic bottles are designed for one-time use, the solution is clear: Use fewer plastic bottles. Manufacturers design plastic bottles for one-time use only. Swapping out plastic bottles for more permanent solutions, such as bottles made from stainless steel, is better for your health and for the environment.
