More Dangers of Plastic Water Containers
April 27, 2005
Drinking from brass water containers could help protect against
water-borne bacteria such as E. coli. This is because, according
to researchers, bacteria are less likely to flourish in brass water
containers than in earthenware or plastic ones. These findings are
especially prominent for poor regions of the world where water-born
diseases continue to be a serious health threat. In these areas,
2 million children die each year from diarrhea.
Thus, in an effort to determine if brass truly is superior to other
forms of water containers, researchers conducted a series of experiments.
Is Brass the Better Choice?
Brass and earthenware containers were filled with a diluted culture
of E. coli bacteria. After six, 24 and 48 hours, researchers counted
the surviving bacteria and found:
- The amount of E. coli in the brass containers dropped significantly
- After 48 hours they fell to undetectable levels.
Why does brass eliminate bacteria? For
starters, brass is an alloy of zinc and copper. Containers made
of brass shed copper particles into the water and the copper acts
by interfering with the membranes and enzymes of cells -- meaning
death for bacteria. The amount of copper a human would
drink in 10 liters of water stored in a brass container wouldn't
even account for the daily recommended level of that mineral in
a healthy diet.
Also, brass water containers proved to be better than cheaper,
plastic ones. In light of this evidence, researchers hope people
with make the healthy switch to brass containers.
