Fig. 4. Examples of measured concentration versus distance profiles for naphthalene diffusion at either high initial concentration (C_h, open symbols) or low initial concentration (C_l, closed symbols) at selected contact times (equilibrium time + incubation time) in (a) Hiroshima ( ${theta}$ ${approx}$ 0.13 m³ m^-3, t = 722 h), (b) Yolo ( ${theta}$ ${approx}$ 0.18 m³ m^-3, t = 504 h) (c) Lerbjerg 5 ( ${theta}$ ${approx}$ 0.24 m³ m^-3, t = 386 h), (d) Lundgaard ( ${theta}$ ${approx}$ 0.07 m³ m^-3, t = 143 h) and (e) Forbes ( ${theta}$ ${approx}$ 0.21 m³ m^-3, t = 2448 h). The lines are model fit (Eq. [5]) to measured data to obtain the D_eff value.
