Ambient settleable (dustfall) dust particles samples were collected during August 2009
to March 2010 from 18 locations in Sulaimani City/KRI for qualitative analyzing by
Fourier Transform Infrared (FTIR) spectroscopy instrument to characterize the common
functional groups that existed in the samples. Furthermore, the samples were
quantitatively analyzed for the heavy metals contents of; V, Co and As by Inductively
Coupled Plasma-Optical Emission Spectroscopy ICP-OES. The collected samples
involved samples of settleable dust particles from local source of the city (location 1 to
15) and settleable dust particles from dust storm event of 22 February, 2010 (location 16
to18). The FTIR analysis identified the following functional groups; Sulfinate ester;
Sulfoxide; Sulfate ion; P. Amine (bend.); Carbonyl; Thiol; Alkanes HC; P. Amine (str.);
Bonded and free hydroxyl group in all the samples of (1 to 15) for the local source of
dust particles except sample location number 6 which was free from sulfoxide, p. amine
(bend.), carbonyl and p. amine (str.) as compared to the samples of other locations and
it was also the only sampling location that had a silicate group. Moreover, sample
location number 13 was the only location that had an extra functional group of isocyanide
or alkynes HC functional group. For the dust storm samples of location numbers 16, 17
and 18 had also all the above mentioned 9 functional groups except the alkanes HC
functional group. On the other hand, the concentration ranges of the studied heavy metals
were (0.20 – 3.20), (2.02 – 5.45) and (2.89 – 45.50) mg dust kg-1 dust for As, Co and V
respectively in all the studied locations.
