Trihalogenated anisoles (THAs) that have been identified at low concentration levels (ngL(-1)) in drinking water are suspected of causing odor episodes, which are a frequent source of complaint by consumers. Henry's law constant (K(H)) is an important parameter in controlling the diffusion of organic compounds from the water to the vapor-phase, so its evaluation is of significance in the study of odor events. In this paper, the K(H) of a wide range of trihalogenated anisoles--in its dimensionless form [Formula: see text]--were calculated at two temperatures, 45 and 22 degrees C using equilibration partitioning in a closed system and headspace microextraction (EPICS-SPME). Two methodological approaches, Ramachandran and Dewulf, were used for the assessment of the Henry's law constant. Nevertheless, to apply these methods to THAs, a relatively narrow headspace/water volume ratio range (80/1-8/1) is required. At these conditions, a linearity (r(2)) using Ramachandran's theoretical relationship from 0.9276 to 0.9989 was obtained and the variability (R.S.D.%) when Dewulf's theoretical relationship was employed was lower than 20% (n=5).
