12.3 Bioaccumulative potential

An estimated BCF of 60 was calculated in fish for budesonide(SRC), using a log Kow of 3.20(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

12.4 Mobility in soil

The Koc of budesonide is estimated as 120(SRC), using a log Kow of 3.20(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that budesonide is expected to have high mobility in soil(SRC).
