geosmin (GSM) and 2-methylisoborneol (MIB. The new nose-like device can detect these smells at very low concentrations of just 10ng per liter of water.

geosmin (GSM) and 2-methylisoborneol (MIB. And while these molecules aren harmful in water, they smell earthy and musty, respectively,

the researchers found human olfactory receptors that react to GSM and MIB, and bound them in carbon nanotubes.

In tests, the researchers found that their device could detect GSM and MIB concentrations as low as 10 nanograms per liter of water,

which can detect GSM at just 5 parts per trillion, but it's a good start.
