Mobile phones getting less toxic

Do you ever heard that there is toxic in your cell phones? 
Do you know that cell phones and batteries are some of the largest contributors of toxic substances to our landfills?

Even Brain doesn't pay attention to it.
But as a future electronic engineer, every aspect must be take seriously.

But the toxic in cell phones are getting less as the technology growth.
Some researcher from USA had done their research and said that..


The Motorola Citrus, Apple iPhone 4S and LE Remarq emerged as the least toxic cell phones in a study of 36 different models that have come onto the market during the past five years, the Michigan-based Ecology Center said.

The newly released iPhone 5 ranked fifth, and its arch rival Samsung Galaxy S III ninth, while the iPhone 2G—the first in the top-selling smartphone series, released in 2007—was found to contain the most toxic materials.

"The takeaway is that mobile phones are chemically intensive, and full of chemical hazards, but they've been getting a lot better," Jeff Gearhart, research director at the Ecology Center, told AFP in a telephone interview.

In a statement, the Ecology Center explained that "every phone sampled in this study contained at least one of following hazardous chemicals: lead, bromine, chlorine, mercury and cadmium." 

Such dangerous substances can pollute at any stage of a product's life cycle, from the moment they are extracted from the ground to the time a cellphone is assembled and the day it is thrown out, it said. 

"Consumer interest in healthier products is driving companies to design and produce healthier products," said Gearhart, who also cited tougher controls in Europe and Asia over the hazardous materials used in consumer electronics. The Ecology Center—which posted its findings on its HealthyStuff.org website—has previously looked into the extent of toxins in automobiles, children's car seats, jewelry, garden hoses and Halloween products.

Suprising that even Iphone 5 is more toxic than Iphone 4s.
Guess that there has to be an invention toxic tester on the cell phones or other gedget for the consumer to have a better living.
