Table 1.

Measurements of the WSON in the gas phase and fine-mode particles (PM_2.5) from the denuder–filter pack system, and in the fine-mode particles (PM₂) and coarse-mode particles (d > 2 μm) from the impactor with a backup filter. ‘S.D.’ and ‘I.R.’ denote the standard deviation and interquartile range, respectively. Unit is μg m⁻³ except for ‘n’.
