the health risks of plastic containers
The Health Risks of Plastic Containers
  • Not limited to just bottled water
    • Food containers, baby bottles, plastic wrap, 5 gallon water containers, sports squeeze bottles, Styrofoam, etc…
  • Although the FDA has approved all plastics currently being used to package food, they might not all be safe
  • The release of harmful toxins usually occurs with prolonged storage, or increased storage temperatures.
good plastics vs bad plastics
Good Plastics vs. Bad Plastics
  • Bad Plastics
    • Polyvinyl Chloride (PVC)
    • Polystyrene (PS)
    • Poly Carbonate, which contains bisphenol-A (BPA)
  • Better Plastics
    • Polyethylene terephtalate (PET or PETE)
    • Polypropylene
polyvinly chloride pvc
Polyvinly Chloride (PVC)
  • Considered to be most hazardous consumer product ever created
    • Cooking oil bottles, clear food packaging, children's toys, industrial piping
  • Mercury, dioxins, phthalates, toxins can leech from PVC
  • Irreversible life long threats, which can cause cancer and harm immune and reproductive systems
polystyrene ps
Polystyrene (PS)
  • Styrofoam is one form of polystyrene
  • Common household product which can leech styrene into food
    • Disposable plates and cups, meat trays, egg cartons, carry out containers
  • Human carcinogen, which is hazardous for consumption
poly carbonate bpa
Poly Carbonate - BPA
  • Contains the hormone disruptor bisphenol-A (BPA)
  • Used mostly in baby bottles and reusable sports bottles
    • Poses a risk of improper brain development in infants and children
    • Not recommended for mothers that are pregnant or nursing
  • BPA interfere with hormone levels
    • People with high levels of BPA have higher risk of developing uterine fibrosis, breast cancer, and prostate cancer
better plastics pet pete
Better Plastics – PET/PETE
  • Polyethylene terephthalate (PET or PETE), is safer to use
  • Easily recycled
    • Commonly found in water bottles, soda bottles, salad dressing, etc…
  • Does not contain BPA, but studies have shown to still leech harmful toxins if kept on a shelf for long periods of time
to recycle or not to recycle
To Recycle or not to Recycle?
  • When recycling, look for the triangle with the # 1
  • More and more communities are starting to accept #2, 4, and 5 for recycling
  • # 3 and 6 very difficult to recycle and is bad for the environment
why bottled water
Why Bottled Water?
  • Convenient on the go
  • Tastes better
  • Unsure about the quality of tap water
why not tap water
Why not tap water?
  • Drinking water in the U.S. is some of the safest in the world
  • 90% of Americans are serviced by public water systems
  • Quality regulated under the Safe Drinking Water Act and many other regulations
alternatives to harmful plastics
Alternatives to harmful plastics
  • Tap water with water filter
  • Consume bottled water (with the proper recycle code) shortly after being bottled by the manufacturer
  • Aluminum or stainless steel water bottles
  • Try to heat food in containers not containing plastic
  • Release of harmful toxins can lead to serious health risks
  • Vigilantly seek out plastics which are better for you to use
  • Try to use only PET/PETE type plastics
  • Use other alternative methods whenever possible
  • Save the environment…..RECYCLE
