no data available

12.3 Bioaccumulative potential

An estimated BCF of 360 was calculated for 1-dodecanethiol(SRC), using an estimated log Kow of 6.18(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), provided the compound is not metabolized by the organism(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of 1-dodecanethiol can be estimated to be 1.1X10+4(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-dodecanethiol is expected to be immobile in soil.
