This is not to scare you but to call your attention to caution
What is dioxin?
Dioxins are environmental pollutants. They belong to the so-called “dirty dozen” – a group of dangerous chemicals known as persistent organic pollutants (POPs). Dioxins are of concern because of their highly toxic potential. Experiments have shown they affect a number of organs and systems.
Once dioxins enter the body, they last a long time because of their chemical stability and their ability to be absorbed by fat tissue, where they are then stored in the body. Their half-life in the body is estimated to be 7 to 11 years. In the environment, dioxins tend to accumulate in the food chain. The higher an animal is in the food chain, the higher the concentration of dioxins.
Sources of dioxin contamination
Dioxins are mainly by-products of industrial processes but can also result from natural processes, such as volcanic eruptions and forest fires. Dioxins are unwanted by products of a wide range of manufacturing processes including smelting, chlorine bleaching of paper pulp and the manufacturing of some herbicides and pesticides.
Dioxin in water bottle
People should not drink bottled water that has been left in a car. The heat reacts with the chemicals in the plastic of the bottle which releases dioxin into the water. Dioxin is a toxin increasingly found in breast cancer tissue. Dioxin is a carcinogenic(cancer causing) chemical. I would also advise against bottle water or sachet water left standing under sun for a prolonged period of time.
Heating food in the microwave using plastic containers especially foods that contain fat should be completely avoided.
The combination of fat, high heat and plastic releases dioxin
into the food.
Instead use glass, such as Pyrex or ceramic containers
for heating food… You get the same result, but without the dioxin.
Dr. Halden(John Hopkins researcher) did note that drinking water from plastic bottles that had been exposed to high temperatures could be problematic:
There is another group of chemicals, called phthalates that are sometimes added to plastics to make them flexible and less brittle. Phthalates are environmental contaminants that can exhibit hormone-like behavior by acting as endocrine disruptors in humans and animals. If you heat up plastics, you could increase the leaching of phthalates from the containers into water and food.
