Bottles, bottles, bottles

By now I think we are all aware that plastic bottles are generally unsafe. I try to avoid buying any liquid unless it is in a glass bottle (of course, then there is BPA in the lid, sigh...). Today I saw that there is yet another new study from the Journal of Environmental Monitoring to reinforce that habit.

Scientists at the University of Copenhagen detected high levels of antimony in some commercial juices. Testing was done on various juices packaged in polyethylene terephthalate (PET) bottles, glass bottles and Tetra Pak cartons. Antimony concentrations up to a factor of 2.7 above the EU limit for drinking water were found and may have leached from the packaging or may have been introduced during manufacturing process. The chemical of concern in this situation, antimony trioxide (a suspected carcinogen) is used as a catalyst in PET production.

You can read more here:
The danger of antimony is described as follows: "Antimony and many of its compounds are toxic. Clinically, antimony poisoning is very similar to arsenic poisoning. In small doses, antimony causes headache, dizziness, and depression. Larger doses cause violent and frequent vomiting, and will lead to death in a few days." The article goes on to say that, "More recent research suggests that antimony may have endocrine-disrupting effects at concentrations lower than the limits noted above; if so, then leaching of antimony from PET containers may have a significant impact on human health." [Sax, Leonard (2009). "Polyethylene terephthalate may yield endocrine disruptors" (free access). Environmental Health Perspectives.]

Antinomy compounds are used in such applications as flame-retardants - exactly the kind of thing you do NOT want to pour into your child's sippy cup. So, we'll stick to glass.
