All the equilibrium time are 594 hours except that δ-BHC's is 234 hours and both p, p'-DDE and o, p-DDT's are 70 hours. Uptake rates of α-BHC, hexachlorobenzene,β-BHC,γ-BHC,δ-BHC, heptachlor, aldrin, heptachlor epoxide, p, p'-DDE, dieldrin, endrin, p, p'-DDD, o, p-DDT and p, p'-DDT are 0.061, 0.071, 0.098, 0.066, 0.033, 0.014, 0.007, 0.062, 0.108, 0.052, 0.029, 0.032, 0.061mL/h, respectively.
