After conducting its own "independent lab tests," the Center for Environmental Health (CEH), a non-profit consumer watchdog group, has concluded that the headphone cords for both the iPhone and iPod do indeed contain high levels of phthalates. While the previous Greenpeace analysis found 5070 parts per million (ppm) of dibutyl phthalate (DBP) in the iPhone headset cable, the CEH's subsequent testing actually found 6200 ppm of DBP in the headset cable of the phone and 6300 ppm DBP in the iPod headset cable. That, according to the safety group, violates California state standards.Source: Wired Blog Network, 11/08/07
