According to Bo Börstell and colleagues at Malmö-based contract testing laboratory IMTEC, mobile phones warmed to body heat, as they could be when pressed against the ear, emitted a range of chemicals, including phenol, cresol and biphenyls. They suggest that these could enter mobile phone users' bodies through the skin or by inhalation. "This may explain why many frequent users of mobile phones complain over constant headaches and dizziness," Mr Börstell told Swedish magazine New Technology, which first reported on the IMTEC scientists' two-year investigation.
Responding to the news, Mats Pellbäck-Scharp of major Swedish mobile phone maker Ericsson said he couldn't understand where the chemicals originate from. "We will of course look into this immediately," he told New Technology. Sweden's Chemicals Inspectorate has requested a copy of the scientists' report for evaluation and the Swedish Institute for Research on the Workplace will also follow-up the research.
Mr Börstell and colleagues are not sure where the chemicals originate. "They may come from details on the phones made from phenolic plastic. Another source may be the liquids used to facilitate the release of the phone shell from plastic presses at the factory. Circuit cards may also be the villains," Mr Börstell said.
