Determination of mercury in size-segregated ambient particulate matter using CVAAS

The Hgp mass size distribution was unimodal in the winter and in the whole 2013 year and trimodal in the summer. The absolute maxima of the distribution density functions (main modes) occurred in 0.4-0.65 μm for the year, 0.4-0.65 μm for the winter, and 0.65-1 μm for the summer. The two remaining maxima for the summer distribution were in 2.5-4.4 μm and 6.8-10 μm.
