Some of the common health issues in low income communities observed around the world come from drinking contaminated water.Runoff from farms, and industrial wastes and mining can all put heavy metals, such as lead and copper, into waterways. Current methods of removing heavy metals from water are expensive, and some substances used in the process are toxic themselves.
A recent research found that minced banana peel could quickly remove lead and copper from river water as well as/better than many other materials. A purification apparatus made of banana peels can be used up to 11 times without losing its metal-binding properties. The banana peels are very attractive as water purifiers because of their low cost and because they don’t have to be chemically modified in order to work: http://pubs.acs.org/stoken/presspac/presspac/full/10.1021/ie101499e
