Environmental Issues - Nalgene & BPA

Nalgene is a distributor and manufacturer of plastic laboratory containers that has diversified into the field of containers for outdoor sports. There are many other brands of sports bottles on the market today that are made from polycarbonate plastics.

Possible Health Risks

In recent years, studies have suggested that polycarbonate plastics such as the ones Nalgene used may leach endocrine disruptors. Among the secreted chemicals, Bisphenol-A (BPA) is an area of concern as it binds to estrogen receptors, thus altering gene expression. Other research has found that fixatives in polycarbonate plastics can cause chromosomal error in cell division called aneuploidy.

In November 2007, Mountain Equipment Co-op removed all hard, clear polycarbonate plastic water bottles (including Nalgene-branded product) from their shelves and no longer offers these items for sale. In December 2007, Lululemon made a similar move. In May 2008, REI removed Nalgene-branded polycarbonate water bottles.

On April 18, 2008, Health Canada announced that Bisphenol A is "toxic to human health". Canada is the first nation to make this designation.

What are the sources of Bisphenol A in my home?

Because of its wide range of applications, Bisphenol A can be commonly found in many products in the home. Polycarbonate plastics are used in food and drink packaging, including water and baby bottles, compact discs, safety equipment, and medical devices. Epoxy resins are used to coat metal products, such as food and drink cans, water supply pipes, and bottle tops. Some other common household products that contain Bisphenol A include:

• Children's toys
• Dental sealants
• Reusable drink containers
• Microwavable food containers (typically marked with a #7 on the bottom)
• Electronic equipment
• Sports helmets
• Eyeglass lenses
