Temperature coefficients of sorption and the heat of sorption were tabulated 
(221) and the mechanism of sorption on moist soils investigated (223). 
The steady-state diffusion coefficient of ethylene dibromide in soils 
was related to the free diffusion coefficient. 
D=0.066D (S-0.1) 
Do= diffusion coefficient in free air 
S = porosity 
Unsteady-state coefficients were calculated from 




apt Yk (PAO 
K (HB+S) 
and tabulated (222).
