For example, considering the range of 95% in a population with GSD of 2, the exposure level of 97.5%ile is approximately 15 times of that of 2.5%ile. For other GSD values, refer to the linked table.  Exposure Concentration Type Material GSD Status Personal exposure chloroform benzene toluene formaldehyde nitrogen dioxide 4.40 3.37 4.63 (1.49-1.75*) (1.25-2.11*) 2006.6.30 Update 2006.6.30 Update 2006.6.30 Update 2007.4.24 Update 2007.4.24 Update Indoor concentration chloroform benzene toluene formaldehyde nitrogen dioxide 4.72 2.10 5.00 1.90 (1.50-2.79*) 2006.7.30 Update 2006.6.30 Update 2006.6.30 Update 2007.4.24 Update 2007.4.24 Update Outdoor concentration chloroform benzene toluene formaldehyde nitrogen dioxide 3.42 1.68 2.76 2.46 1.78 2006.6.30 Update 2006.6.30 Update 2006.6.30 Update 2007.4.24 Update 2007.4.24 Update * Range of GSD value from individual studies.
