Clay and papaya seeds could mean clean water for millions

A simple combination of clay and papaya seeds can clear water of harmful metals more cost-effectively than current commercial options, a study reveals.

Heavy metals such as lead, cadmium and mercury contaminate many water supplies in developing countries. In many cases, carbon-activated adsorption technologies are too expensive to install in areas that need them most.

Researchers hope that this new “hybrid clay” will provide a cost-effective replacement for the current activated carbon treatments, allowing millions to access clean water for drinking and cooking.
