Jaiho Cho et al.
Chemosphere, 68(2), 266-273 (2007-02-16)
The biodegradability of alkylate compounds in serum bottles was investigated in the presence and absence of ethanol or benzene, toluene, ethylbenzene, and p-xylene (BTEX). The biomass was acclimated to three different alkylates, 2,3-dimethylpentane, 2,4-dimethylpentane and 2,2,4-trimethylpentane in porous pot reactors.

This paper describes apparatus and methods for measuring uptake of inhaled vapors in the nose and lungs of dogs. The system allows sampling of air from the trachea at specific times during inspiration and expiration without surgical manipulation of the
A R Dahl et al.
Toxicology and applied pharmacology, 109(2), 263-275 (1991-06-15)
The site of uptake of inhaled vapors profoundly influences which respiratory tract tissues receive the highest doses. How the site of uptake depends on the physicochemical properties of inhaled vapors has been the subject of experiment and speculation for decades
