iPhone 4S and iPhone 5 use materials that do not contain many toxic chemicals

  The smartphones and tablets that we use in our daily lives are built using various materials that are manufactured or treated with various chemicals. Many of these chemicals are toxic, too a new study had the role of checking whether the smartphones now sold on the market use such substances or not and whether they are dangerous for people. In the image above you can see the results of the study and notice that Motorola Citrus is the phone with the fewest toxic chemicals, it is followed by iPhone 4S, Lg Remrq, Samsung Captivate, iPhone 5 and Samsung Evergreen.

  36 terminals were tested, 6 were categorized as having a low risk degree, 24 have a medium risk degree and 6 have a high risk degree. All the ones with a high degree of risk were produced before 2010, the iPhone 2G has the highest score among them, so if you have one around the house, you'd better give it up. Over the years, Apple has improved the production process of its own smartphones, this is highlighted by the study, but in the iPhone 5 something new was used that generated a very small decrease in the quality of the materials.
