AB  - This work presents, for the first time, information on the adsorption-desorption 
      characteristics of illicit drugs and precursors in soils and an estimation of 
      their potential bioavailability. The experiment was conducted using a batch 
      equilibrium technique for the parent drugs methamphetamine and 
      3,4-methylenedioxymethamphetamine (MDMA) and the precursor pseudoephedrine in 
      three South Australian soils varying in physiochemical properties. The individual 
      compounds exhibited different adsorption mechanisms in the test soils, and the 
      results fitted better with the Freundlich isotherm model (r (2) >/= 0.99). The 
      maximum adsorption capacity was recorded for pseudoephedrine (2,000 mug g(-1)). 
      However, pseudoephedrine recorded lower organic carbon normalized adsorption 
      coefficient values (<250 mL g(-1)), lower magnitudes of Gibb's free energy 
      change, and higher percent desorption (73-92 %) compared to methamphetamine and 
      MDMA. The results thus showed pseudoephedrine to be the most mobile compound in 
      the soils under study, to have the highest availability for degradation of the 
      three compounds, and to have the highest susceptibility to biotic degradation in 
      test soils.
