Tests for nano toxicity coming later this month

A framework for assessing the potential health effects from inhaling or otherwise being exposed to nanoparticles will be released in Washington October 24.

The framework--prepared by the Nanomaterial Toxicity Screening Working Group of the International Life Sciences Institute Research Foundation/Risk Science Institute (ILSI RF/RSI)--outlines methods for testing for possible toxicity caused by nanomaterials, which are particles measuring 100 nanometers or less. (a nanometer is a billionth of a meter.).

While nanoparticles present potential health risks to the general public wearing pants or other products containing nanoparticles, the more likely health risk will be to factory workers who will work with these materials directly. Medical researchers also warn that molecular medicines could have unanticipated consequences.

Scientists have also expressed concerns that worries about health risks could crimp funding.
