Size-segregated trace elements in continental suburban aerosols: seasonal variation and estimation of local, regional, and remote emission sources.

We have measured trace element contents in suburban aerosols from six size fractions in the range of PM from a background station in Belgrade (Serbia). The distribution and concentration of elements were determined within each of the investigated Dp fractions with emphasis on the fine and coarse modes. Fine/coarse mode ratios of element can provide information regarding their anthropogenic or natural origin.

Partitioning of particulate matter and elements of suburban continental aerosols between fine and coarse modes.

The results presented in this work demonstrate for the first time a distribution of elements in the spectral analysis of aerosols in the suburban continental Balkan Peninsula. Samples were collected in the suburban area of Belgrade (Serbia) in the period from March 2012 till December 2013. Results presented here are from long-term measurements of masses of size-segregated aerosols and macro- and microelements in the range of PM.
