To Leach His Own

Nalgene Water Bottles May Be Hazardous to Your Health

Here's some bummer news for the outdoorsy set: Recent studies have shown that polycarbonate plastics, including the kind used in popular Nalgene water bottles, may leach one of their constituent chemicals into water. The chemical in question, bisphenol-A, has been shown to cause chromosomal disorders and endocrine disruption and to have adverse effects on prostate development and tumors, breast tissue development, and sperm count -- in rodents. Nalgene says that no health problems have been demonstrated in human beings. Still, John P. Myers, environmental health expert and coauthor of a book on endocrine disruptors, says, "I personally recommend avoiding polycarbonate plastics -- don't let them come into contact with your food or water. I think the science is strong enough to justify precautionary measures today." What's next -- carcinogenic Therm-a-Rests? Is nothing sacred?
