A new US study published June 30 suggests the surfaces in your office could be covered in a coating of toxic dust.

Researchers discovered concentrations of a banned flame retardant called polybrominated dipheny ether (PBDE) on the hands of workers who spent at least 20 hours a week in an office. The study evaluated 31 offices in Boston, Massachusetts, and researchers noted that the amount of PBDE on workers' hands was linked to how much was measured in their blood.
