“…As this is the first joint investigation of the chemical composition of two types of pollutants in that location, where no chemical air quality monitoring existed at the time, the data are limited to a qualitative analysis of atmospheric particulate matter (PM) including selected particle size, morphology and chemical composition, as well as the content of selected POPs in samples of atmospheric air collected during the spring season 2019 in Hornsund (Svalbard). However, we deem our data offer valuable insight since April and May 2019 have already been shown to be impacted by atypically high concentrations of chlorinated POPs in snowfall at Hornsund [33], while recent work suggests that the Arctic haze season may be shifting towards later months of spring [2,6].…”

The character of atmospheric pollution and its impact on surface waters may vary substantially in space, and hence, we add a potentially important location for the studies of atmospheric air pollution to the map of the High Arctic. We have investigated the anthropogenic particle characteristics and selected persistent organic pollutant concentrations, in a priorly unmonitored location in the Arctic (Svalbard), exposed to a climatic gradient. Single-particle analysis of PM indicates that besides the prevailing natural aerosol particles, anthropogenic ones were present. The likely anthropogenic origin of some particles was established for spherical Fe-rich or aluminosilicate particles formed in high-temperature processes or metal-rich particles of the chemical composition corresponding to industrial products and atypical for natural minerals; soot, tar balls, and secondary sulfate were also likely of anthropogenic origin. Some of the observed anthropogenic particles could only come from remote industrial sources. POP concentrations indicated a background of LRAT, consistent with the ΣPCB concentrations and volatility profile. However, the ΣDDX composition indicating aged sources and an order of magnitude higher concentrations of both ΣDDXs and ΣHCHs than at other High Arctic monitoring stations indicate their potential source in two types of re-emission from secondary sources, i.e., from seawater and snowpack, respectively.
