This study quantifies the elemental composition of soil, vegetation, and the level of trace elements in coals to identify the impacts associated with coal mining practices in the Longyearbyen and Barentsburg settlements, the Svalbard archipelago. The analysis is based on a data set that includes 26 chemical elements measured in 74 soil, 29 vegetation, and 4 coal samples provided by a catena-based survey strategy. The concentrations of lead (Pb), nickel (Ni), copper (Cu), zinc (Zn), chromium (Cr), and vanadium (V) in the soils did not exceed the European regulatory standards (the Finnish Standard and the Norwegian Soil Quality Standard), while arsenic (As) and cadmium (Cd) overstepped their threshold values in some soils. The Geoaccumulation Index (Igeo) values showed that soils were enriched in titanium (Ti), strontium (Sr), boron (B), and zirconium (Zr). The elemental screening of the exposed coals, soils, and vegetation revealed high concentrations of these four elements as well. The examination of geospatial patterns shows that the concentrations of Ti, Sr, Zr, and B in the soils are distributed evenly along the most of the sampling transects (catenas). While the distribution of elements in the soils between the transects (catenas) varies considerably, the highest concentrations for Ti, Sr, B, and Zr are observed near the currently operating coal mining and transportation facilities.
