Mobile phones are being built using fewer toxic chemicals than were their predecessors, and Apple's iPhone 4S and iPhone 5, along with many other newer phone models, are among the least toxic to have been released in more than a decade. This according to a new report out from iFixit and HealthyStuff.org. The two sites performed chemical analyses on 36 phones, finding that Apple's two newest models ranked in among the five least toxic, along with models from Samsung and Motorola.
