| 英文摘要 | Personal exposure and ambient fine particles (PM2.5) measurements for 13 adult subjects (ages 19-57) were conducted in Hong Kong between April 2014 and June 2015. Six to 21 personal samples (mean = 19) per subject were obtained throughout the study period. Samples were analyzed for mass by gravimetric analysis, and 19 elements (from Na to Pb) were analyzed using X-Ray Fluorescence. Higher subject-specific correlations between personal and ambient sulfur (r(s) 0.92: p < 0.001) were found as compared to PM2.5 mass (r(s) 0.79; p < 0.001) and other elements (0.06 < r(s) < 0.86). Personal vs. ambient sulfur regression yielded an average exposure factor (F-pex) of 0.73 +/- 0.02, supporting the use of sulfur as a surrogate to estimate personal exposure to PM2.5 of ambient origin (E-a). E-a accounted for 41-82% and 57-73% of total personal PM2.5 exposures (P) by season and by subject, respectively. The importance of both E-a and non-ambient exposures (E-na, 11.2 +/- 5.6 mu g/m(3); 32.5 = 10.9%) are noted. Mixed-effects models were applied to estimate the relationships between ambient PM2.5 concentrations and their corresponding exposure variables (E-a,P). Higher correlations for E-a (0.90; p < 0.001) than for P (0.58; p < 0.01) were found. A calibration coefficient < 1 suggests an attenuation of 22% (ranging 16-28%) of the true elect estimates when using average ambient concentrations at central monitoring stations as surrogates for E-a. Stationary ambient data can be used to assess population exposure only if PM exposure is dominated by E-a. (C) 2018 Elsevier B.V. All rights reserved. |
