PROBLEMS AND CONSTRAINTS IN THE USE OF THE FUGACITY MODEL
A limitation inherent in the original form of the fugacity model is the absence in the unit world for biota other than aquatic animals. Terrestrial plants are a very important component due to their biomass and to the possibility of transfer of contaminants to higher levels, including man, of the trophic chain.
On the other hand, as has been previously emphasized, the inclusion of a new compartment into the model is conceptually an easy task, requiring only the calculation of the Z value once partition coefficients are known.
