Bottled Water:

Risk Factors from Human Consumption and the Environment

Delile Langeni, Ph.D. student

PH 8165-2

Instructor: Dr. Raymond Thron

Spring, 2009

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
