AB  - Dimethylsilanediol (DMSD) is the common breakdown product of methylsiloxanes such 
      as polydimethylsiloxane (PDMS) and volatile methylsiloxanes (VMS) in soil. In 
      this work, we first present a sorbent selection experiment aiming to identify a 
      sorbent that can trap gas-phase DMSD without causing DMSD condensation and VMS 
      hydrolysis at environmentally relevant humidities. With a proper sorbent (Tenax) 
      identified, the volatilization of DMSD from water and various wet soil and soil 
      materials were measured in a controlled environment. It was demonstrated that 
      DMSD underwent volatilization after soil water was completely evaporated. Various 
      types of soil constituents show drastic differences in preventing DMSD from 
      volatilization. Analysis of the sorbent-captured products provides further 
      insight, most notably that virtually no cyclic methylsiloxanes are formed during 
      the volatilization of DMSD from water or soil materials, except in one extreme 
      case where only traces are detected.
