After reading many articles about plastic bottles here are some key paragraphs about using plastic bottles, its fine as a one use product as that’s what it’s designed for but it shouldn’t be reused.
At the bottom of plastic containers there is a number from 1 through to 7.
Environmentalists say to avoid numbers 1,3,6 and 7
1 – PET/PETE (polyethylene terephthalate): Made for one time use, these bottles should be avoided since they more than likely leach the heavy metal antimony and the hormone disrupting chemical BPA. Don’t reuse these bottles and don’t purchase if they are over six months old.
3 – PVC (polyvinyl chloride): Known to leach two toxic chemicals, DEHP (di-2-ehtylhexyl phthalate) and bispehonal-A that are both known endocrine and hormone disruptors, this is the most common plastic used in water bottles, baby bottles and cooking oil.
6 – PS (polystyrene): Known to leach styrene, a carcinogen that causes headaches, fatigue, dizziness, confusion, drowsiness, this plastic is most commonly used in disposable coffee cups and take out containers.
7 – PC/PLA: Polycarbonate is made with BPA as it is known to be absorbed into the body as is beginning to be linked with, diabetes heart disease.
It is said PET bottles contain diethylhydroxylamine(water soluble) or DEHA which is potentially carcinogenic.With Repeated washing the plastic on the inside will breaks down releasing these chemicals.
Study Shows Plastic Mineral Water Bottles Contaminate Water with Estrogen.
Researchers found evidence of estrogenic compounds leaching out of the plastic packaging into the water. What’s more, these chemicals are potent in vivo and result in an increased development of embryos in the New Zealand mud snail. These findings, which show for the first time that substances leaching out of plastic food packaging materials act as functional estrogens, are published in Springer’s journal Environmental Science and Pollution Research.
Reuse of plastic bottles is generally not recommended by commercial bottled water manufacturers,
as it may pose a health risk from two perspectives. First, everyday wear and tear from repeated washings
and reuse can lead to physical breakdown of the plastic, such as visible thinning or cracks. Secondly, reuse of plastic water bottles can lead to bacterial contamination unless washed regularly.
Antimony can be released (i.e., leached) from the PET plastic
used to make commercial and municipal water bottles. While
the rate of leaching is low below storage temperatures of
60 1C, above this temperature antimony release can occur
“A simple water treatment process called SODIS (solar water disinfection) consists of filling polluted
water in PET bottles that are exposed to sunlight for 5–6 hours. However, sunlight does not only
destroy disease-causing microorganisms found in the water but also transforms the plastic material
• synthetic / chemical bonds not perfect
• leaching does occur
• heat is a catalyst – use with caution
• plastic is forever
The dose makes the poison
newer findings suggest
extremely low “doses” are relevant variables in the blame game
total body load, low-dose effect, bioaccumulation, the cocktail effect
Neither the FDA nor the EPA requires manufacturers to test for toxicity of ingredients one at a time new and old chemicals are regulated differently. A note on the TSCA those released prior to 1979 are considered safe (innocent until proven guilty – by the EPA) that is 99% of all chemicals (by volume) on the market today (those chemicals listed in the TSCA Inventory after December 1979) most industrial chemicals have not undergone even basic toxicological testing.
