Time of uptake

By means of Eq. (22) the percentage of chemical steady-state level in relation to time of chemical uptake in half-lives was calculated and presented in Table 1. Furthermore, as an example the uptake of TCDD in medaka was calculated. 95% of the steady-state TCDD level is reached if the time of uptake is 4.3 X half-Hfe and 98.4% is reached in 6 x half-life. This means that for TCDD in medaka (10% Hpid content) 95% of steady-state TCDD level is reached in 1.8 years and 98.4% in 2.5 years, respectively. The experimentally determined half-Hfe of TCDD in medaka was 154 days [28].
