AbstractTo investigate the seasonal variation of organophosphate esters (OPEs) in air particulate matter (PM) and the corresponding influence factors in indoor environment. 104 indoor PM samples were collected in a test home, Harbin, China, from March 2017 to March 2018. The Sigma(1)(2) OPEs concentrations ranged from 0.41 ng/m(3) to 940 ng/m(3). Tris(1-chloro-2-propyl) phosphate (TCIPP) was the most abundant OPE and accounted for 83.2% of the total OPEs. The Sigma(12) OPEs concentrations in spring and summer were higher than those in autumn and winter. Outdoor total suspended partides (TSP) were the main factor that affected the concentration variation of OPEs in PM samples in the test home. Comparisons of the gas/particle (G/P) partitioning equilibrium models indicated that the Dachs-Eisenreich (D-E) model estimates were more reliable than the other models in this study.The partide fractions of OPEs with log K-OA > 10.51 that predicted by all four models generally well matched the measured OPE partide fractions in the literatures. To OPEs with lower molecular weight, inhalation was the main exposure route and ingestion contributed mostly to OPEs with higher molecular weight. In addition, the estimated daily intakes (EDIs) and carcinogenic risks (CRs) posed by OPEs were all below the recommended values, indicating that the current OPE levels in the test home were within the safe thresholds.
