Article Excerpt:

Terra Daily
Washington DC (SPX) Aug 16, 2011

http://www.terradaily.com/reports/Banana_peels_purify_contaminated_water_999.html

topic of the latest episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series.

It actually points out that minced banana peel performs better than an array of other traditional purification materials.

Gustavo Castro and colleagues note in the podcast that mining processes, runoff from farms, and industrial wastes can all put heavy metals, such as lead and copper, into waterways.

Heavy metals can have adverse health and environmental effects. Current methods of removing heavy metals from water are expensive, and some substances used in the process are toxic themselves.
