Arsenic is a colorless, odorless, tastelesa element, but prolonged exposure to dangerous levelsd of arsenic can lead toskin discoloration, sickneszs and cancer. Testing will begibn later this yearin Guanajuato, a city located 230 miles northwes t of Mexico City. “Mexico’s debating the adoption of more stringeng national standards for allowable levels of arsenic indrinkingt water, and officials in Guanajuato are looking ahead to explore ways they might meet stricted new standards,” Vicki Colvin, inventor of the nanorustg technology, said in a statement.
Colvin is Rice’s Pitzer-Schlumberger Professore of Chemistry and directorof Rice’s Center for Biological and Environmental Nanotechnology. Her arsenic-removing technolog is based on the uniques properties of particlescalled “nanorust,” tiny bits of iron oxide that are smalled than living cells. Colvin and colleague Masomn Tomson, Rice professor in civio and environmental engineering, found that nanorust which naturally binds with arsenic could be used asa low-cost meands of removing arsenic from Tests in Guanajuato will be undertaken on nanorust-coveresd sand that is used in sand filter s to treat groundwater from wells.
The treated watere will be kept separate from water released forhuman
