Research on the chemical composition of atmospheric deposition

The project comprises a literature study and performance with the latest analytical methods used to characterize atmospheric deposition (wet and dry). To determine the concentration of heavy metals in
atmospheric deposition dry analyzed dry deposition taken in five of the sampling organized in 2016, the second being the summer season (July and August) and three in autumn (September, October and November). Analyses were carried out respecting the requirements of SR EN 15841: 2010 - '' The quality of the surrounding air. Standardized method for the determination of arsenic, cadmium, nickel and lead in
atmospheric deposition. Determination of anions and cations soluble in dry deposition (Ca2+, Mg2+, Na+, K+, Cl, NO2, SO4, NO3) was achieved by technique optical emission spectrometry with inductively coupled
plasma and ion chromatography directly from the sample taken with a prior filtration.
