...However, TBEP has been measured in both house10 dust (Dodson et al., 2012; Ali et al., 2012; Cequier et al., 2014) and ambient particles (Möller et al., 2012; Salamova et al., 2013)....

...In ambient particles, the concentration of TBEP is often lower than other OPEs found in the remote regions (Möller et al., 2012), while it is comparable with that of other OPEs in urban areas (Salamova et al., 2013)....

...It has also been detected in remote regions, although its concentration is lower than other OPEs (Möller et al., 2011, 2012; Salamova et al., 2014)....

...Recent field measurements suggest that OPEs are persistent in air and can undergo medium to long range transport25 (Möller et al., 2012)....

...In particular, the10 measurements of TPhP in PM in remote regions (Möller et al., 2012), despite its dominant gas-phase loss contribution (based upon our model results) highlights the effect of multi-component particle mixtures on the kinetics of particle degradation....

...…they are used to adequately compute the trace gas and particulate matter content of the5 atmosphere (Kolb et al., 2010), to evaluate the importance of heterogeneous reactions in the atmosphere (Zhang and Carmichael, 1999), and in the assessment of organic aerosol lifetime (Zhou et al., 2012)....

...Using a mass transfer diffusion model (Jacobson, 2005) combined with a partitioning model (Kroll and Seinfeld, 2008; Pankow, 1994)25 (described in detail in the Supplement), evaporation of TBEP is calculated to contribute less than 0.3 % to the particle-phase loss of TBEP within the residence time…...
