Breath-takingly simple test for human exposure to potentially toxic substances

Summary:
The search for a rapid, non-invasive way to determine whether people have been exposed to potentially toxic substances in their workplaces, homes and elsewhere in the environment has led scientists to a technology that literally takes a person's breath away. Their report identifies exhaled breath as an ideal indicator of such exposure.

Their report identifying exhaled breath as an ideal indicator of such exposure appears in ACS' Environmental Science & Technology.

Andrea M. Dietrich, Masoud Agah, and their students Heather Vereb and Bassam Alfeeli explain that scientists have known since the late 1970s that exhaled breath contains traces of any potentially toxic substances that people may have inhaled. Research has shown that those amounts are an accurate reflection of the levels that exist in a person's blood. Those advances have positioned exhaled breath as the ideal substance to use in rapid, non-invasive, simple testing for human exposure to potentially harmful substances in the air. Sampling breath is less invasive than drawing blood, more convenient than taking urine samples and "shows promise as an inexpensive method with a fast turnaround time," they state.

The article describes how advances in microelectronics have helped position breath analysis for more extensive use in the 21st century. Equipment for analyzing substances in human breath that once had to be housed in laboratories, for instance, have shrunk to hand-held size. The technology can detect minute amounts of substances in the breath and do so quickly -- offering the promise of helping limit human exposure and improve health.

The study was supported by the Virginia Tech Institute for Critical Technology and Applied Sciences and the National Science Foundation.
