Abstract Ambient air samples were collected between September 3, 2009 and March 5, 2010 to determine total suspended particulate matter (TSP) and coarse and fine particulate and particle-bound mercury Hg(p) at the suburban/coastal sampling station of Sha-Lu at Taiwan. Results reveal that average concentrations of ambient air particles PM2.5, PM2.5–10, dry deposition, and TSP were 20.5 ± 6.3 (μg/m3), 11.2 ± 4.44 (μg/m3), 162 ± 92.7 (μg/[m2 min]), and 78.7 ± 34.4 (μg/m3), respectively. Average concentrations of PM2.5, PM2.5–10, dry deposition, and TSP of bound mercury Hg(p) were 0.007 ± 0.005 (ng/m3), 0.011 ± 0.006 (ng/m3), 0.156 ± 0.082 (ng/[m2 min]), and 0.07 ± 0.04 (ng/m3), respectively. Average calculated/measured dry deposition flux ratios with coarse (3.8 μm) and fine (0.68 μm) particle size for ambient air particle and particle-bound mercury Hg(p) by using Zhang's combined with William's were 2.49 and 3.44, respectively. Finally, results of this study also indicate that using Zhang's combined with Wi...
