Be careful when using it to interpret standards.  The level listed for isoflurane is 80 mg/cubic meter based on a Swedish study.  More recent NIOSH recommendations are 2 ppm as either a STEL or an 8 hour TWA.

The spore limit is listed at 13 spores per cubic meter and there is no reference given for this number.

Carbon Dioxide Plume Geothermal Technology or CPG

A Minnesota Daily article covers Heat Mining Company' purchase of the CPG technology from the University of Minnesota.

Carbon dioxide from coal fired or natural gas fired power plants is injected into a saline aquifer with a geothermal reservoir.  The heated carbon dioxide produces electricity through an expansion turbine.

I reported on this earlier in 2011.  Dr. Martin Sarr was using geothermal compressed carbon dioxide to produce electricity.
