and slight nausea may also be present.

Exposure may lead to serious oxygen deprivation resulting
in permanent brain damage, coma, even death.
TVOC Levels and Guidelines
Medium (not recommended for exposure > 12
months)
Poor (not recommended for exposure > 1
months)
Note: the conversion from mg/m3 to ppm by the factor is about 0.5 and conversion from ppm to ppb is by the
factor 1000.
Illuminance Levels and Guidelines
No light or minimal street light, twilight.
Family living room, hallways.
Offices, show rooms, study library, laboratories.
