Product quality tests require accurate and precise analytical techniques. Fertilizers belong to a group
of products whose chemical composition is of great importance due to health, environmental and economic
reasons. The following paper presents the results of the research into the content of selected substances in several mineral fertilizers manufactured in Poland. Ion chromatography (IC) was employed to determine selected
inorganic anions and cations, whereas energy dispersive X-ray fluorescence spectrometry (EDXRF) was used
to determine the content of selected elements.
Concentrations and elemental composition of fine (PM2.5) and coarse (PM2.5-10) ambient particles,
at two sampling points located at the same urban background sites, were investigated. The points were 20 m
distant from each other and at various heights (2 and 6 m) above the ground. A dichotomous sampler, equipped
with a virtual impactor, and a cascade impactor were used to sample the dust. An X-ray fluorescence spectrometer was used in the elemental analyses. The investigations revealed heterogeneity of the spatial distribution
and the elemental composition of suspended dust at the investigated urban background site. Coarse dust, whose
concentration at 2.0 m above the ground was affected by secondary emission from roads, soil and other local
low-level sources in some periods, appeared more heterogeneous.
