Or efforts to offset warming by injecting carbon dioxide into underground rocks could make aquifers more acidic, increasing their ability to
leach dangerous metals out of rocks, and leading to higher concentrations of these metals in springs and rivers.
The fact that there has never been any test that showed BPA
leaching from SIGG bottles means that those of us who have used them extensively, even with our children — I was an «early adopter» of
metal bottles and favoured SIGGs over other brands almost exclusively — don't have to panic that we've had
dangerous exposures.
