Sources for soil-to-plant concentration regressions and bioaccumulation factors
Regression models and bioaccumulation factors were obtained from a variety of sources. Preference was given to regression models from EPA’s draft soil screening level guidance (EPA 2000) and Bechtel-Jacobs (1998). Other sources included IAEA (1994), NCRP (1989), and Baes et al. (1984). Values for non-ionic organic compounds not included in the list below are calculated based on Kow using the relationship developed for EPA’s soil screening levels (EPA 2000): BAFplant = 10 1.31- 0.385 logKow.
