They speculated that nitrous acid may be attaching itself to elements found in the ground, only to be released later on.
In fact, nitrous acid could take advantage of different kinds of ground cover for this purpose.
Further, although nitrous acid levels typically reach 5-15 ppb by volume indoors and 30 ppb by volume in vehicles, concentrations as high as 100 ppb by volume have been measured indoors.
In the air, nitrous acid leads to the formation of hydroxyl radicals oxidizing pollutants that then can be washed out.
The authors report that in laboratory tests using cellulose as a model indoor material exposed to smoke, levels of newly formed TSNAs detected on cellulose surfaces were 10 times higher than those originally present in the sample following exposure for three hours to a "high but reasonable" concentration of nitrous acid (60 parts per billion by volume).
