Nickel, arsenic, cadmium, and lead in PM1 fraction in Zagreb, Croatia

Fine aerosol particles have been found to play a key role in global climate change, pollution problems and health hazards. PM1 particles (particulate matter with an aerodynamic diameter of less than 1 μm) are characterized by a high surface-area-to-volume ratio, having great potential negative risks for human health. The metals released by anthropogenic activities, bounded to fine particulate matter, are bioaccumulative and can cause severe ecosystem disturbances. In this study, 24-hour samples of PM1 were collected at an urban background location in Zagreb, during 2011 and 2016, using a low-volume reference sampler. The collected samples of PM1 were prepared in nitric acid using a high pressure microwave digestion system. Nickel, arsenic, cadmium and lead were determined by inductively coupled plasma mass spectrometry (ICP MS). The objective of the study was to determine mass concentrations of nickel, arsenic, cadmium and lead in PM1 fraction in 2011 and 2016 and compare the obtained data sets. The mean annual values were 1.58 ng m-3, 0.45 ng m-3, 0.21 ng m-3 and 5.55 ng m-3 in 2011, and 0.14 ng m-3, 0.23 ng m-3, 0.13 ng m- 3, and 4.33 ng m-3 in 2016 for Ni, As, Cd and Pb, respectively. Statistically significant differences between the years were found for all metals with higher concentrations determined in 2011 compared to 2016. A statistically significant difference was found between seasons as well, except in winter and autumn for As and Pb (in 2011) and As, Ni and Cd (in 2016), and in spring and summer for Ni (in 2011) and Ni, Cd and Pb (in 2016). The highest values during the colder part of the year were found for all of the determined metals which was expected because of the adverse weather conditions that make it difficult to circulate air.
