AB  - Methodology for time-weighted average (TWA) air measurements of semivolatile 
      organophosphate triesters, widely used flame-retardants and plasticizers, and 
      common indoor pollutants is presented. Dynamic non-equilibrium solid-phase 
      microextraction (SPME) for air sampling, in combination with GC/PICI and ion trap 
      tandem MS, yields a fast, almost solvent-free method with low detection limits. 
      Methanol was used as reagent gas for PICI, yielding stable protonated molecules 
      and few fragments. A field sampler, in which a pumped airflow over three 
      polydimethylsiloxane (PDMS) 100-mum fibers in series was applied, was 
      constructed, evaluated, and used for the measurements. The method LODs were in 
      the range 2-26 ng m(-3) for a sampling period of 2 h. The uptake on the SPME 
      fibers was shown to be about five times faster for triphenyl phosphate compared 
      to the other investigated organophosphate esters, most likely due to more 
      lipophilic properties of the aromatic compound. The boundary layer for triphenyl 
      phosphate when using a 100-microm PDMS sorbent was determined to 0.08 mm at a 
      linear air velocity of 34 cm s(-1). Five different organophosphate triesters were 
      detected in air from a laboratory and a lecture hall, at concentrations ranging 
      from 7 ng m(-3) up to 2.8 microg m(-3).
