Goodbye to my Nalgene Bottles
Last week there were several stories in the papers and on television about the danger of bisphenol leaching from plastic drinking bottles. I was busy and did not really pay much attention but with the cold weather this weekend I thought I would use the Google and see what I could find out. Learned a lot. Seems I need to quit listening to rumors. I was always told that you should not use pop bottles for water because they are difficult to clean and bacteria in the bottles could present a health risk. The alternative, Nalgene and other hard plastic bottles. Little risk of bacteria because they are easier to clean but there is a lot of concern about bisphenol leaching from the plastic and getting in the water. According to a 2005 article from the Institute for Agriculture and Trade Policy:
Of 115 published animal studies, 81 percent found signiﬁcant effects from even low-level exposure to BPA. While none of the 11 industry-funded studies found signiﬁcant effects, over 90 percent of government-funded studies did so.
Adverse effects include:
• Early onset of puberty, and stimulation of mammary gland development in females
• Changes in gender-speciﬁc behavior
• Changes in hormones, including decreased testosterone
• Increased prostate size
• Decreased sperm production
• Altered immune function
• Behavioral effects including hyperactivity, increased aggressiveness, impaired learning and other changes in
Ever wonder how industry studies find that there is no issue but the government, 9 out of 10 times discovers the presence of bisphenol.
The Institute for Agriculture and Trade Policy included a simple chart to help assess the risk that plastics present when used to store food and water.
Seems that most soft drink bottles are #1 plastic which is safer. If you choose to continue using bottles manufactured with #7 plastic many articles suggest that you do not warm or freeze liquids in the bottles and consider not using scratched bottles because the scratches harbor bacteria and may speed the transfer of bisphenol.
I am going to go out and buy a stainless steel bottle and say goodbye to Nalgene.
