Common Plastic Found to Leak Chemicals

Two highly reactive chemicals in a common plastic can leak from disposable lab equipment and skew the outcome of life science research, according to an article published Thursday in the journal Science. Researchers from the University of Alberta say the chemicals, which make polypropylene plastic flexible and resistant to bacteria, can have "profound effects" on proteins. That means biologists and drug developers may need to rethink use of single-use test tubes, pipette tips, and other equipment made with polypropylene, a type of plastic usually stamped with the letters PP and number five.

In a time when the FDA is facing criticism for mishandling information about another additive, bisphenol A, this new finding raises questions about polypropylene in consumer products, particularly food and drink containers. According to Rebecca Sutton, a senior scientist from the Environmental Working Group, the potential risks of human exposure to plastic additives should not be overlooked. As she told Globe and Mail environment reporter Martin Mittelstaedt, "We simply don't want these chemicals getting into our bodies."

Lead study author Andy Holt said the health effects of polypropylene additives remain unknown. "I don't think the levels we would be ingesting are likely to turn out to be a problem, but the study needs to be done." His team rushed to publish last week's article not as a health warning, but as an urgent alert to other scientists whose conclusions might be thrown off by contamination.

I believe there are plenty of glass bottles around so that consumers who want to avoid plastic can do so. That does not mean we shouldn't regulate the kinds of bottles in use. We absolutely have to, but until we get EPA 3.0 (2.0 was the brainchild of the Bush administration), nothing of importance will happen.

We've got to break our plastic habit. It's an addiction we and the planet can't afford.

Actually except about three containers and a water bottle I am plastics free. Most of the items (crockery) are either ceramic or stainless steel. I remember, during the mid 80s, my mom stopped packing lunch in my super cool Disney box. LOL.

On the whole life has been plastic free. It has more to do with the overall household policy, instilled during my childhood. Anything non-biodegradable would not be used. There has not been any increase per se in terms of usage. It would be good to use ceramics in my opinion.
