|DON'T DRINK WATER FROM PLASTIC BOTTLES|
Environmental Science & Technology Online January 24, 2007
Scientists have concluded that the longer a bottle of water sits on a shelf -In a grocery store or your refrigerator-you'll consume a greater dose of antimony, a silvery white metal commonly found in gunpowder, anti-parasite drugs, paints, batteries, ceramics, and bearings.
The amount of antimony that leeches into the water you're drinking depends on the bottler and can vary greatly. Among 63 brands of bottled water, researchers detected concentrations of more than 100 times the typical level of antimony in clean groundwater (2 parts per trillion).
What's worse, after letting bottled water samples sit for six months on a shelf at normal room temperatures, the concentration of antimony exploded by 90% among certain brands. Most products were packaged in polyethylene terephthalate (PET) containers-plastic bottles marked with the number 1 in the recycling triangle on the bottom of the bottle.
The researchers believe that the amount of leeching will differ, based on exposure to sunlight, higher temperatures and varying pH levels.
