“…Furthermore, the mass median aerodynamic diameter (MMAD) of airborne Sb was 0.6 μm, which also indicates that Sb tends to concentrate in fine particles. 33 For example, Almeida et al 43 observed a Sb PM2.5 /Sb PM2.5–10 ratio of 1.6 (equivalent to Sb PM2.5 /Sb PM10 of 61.5%) from samples collected in Bobadela on the western coast of Europe. Fujiwara et al 28 found enriched Sb in the smallest particle sizes in road dust samples collected in Buenos Aires.…”

Antimony (Sb), a priority pollutant listed by the U.S. Environmental Protection Agency (USEPA), can cause adverse effects on human health, with particular impacts on skin, eyes, gastrointestinal tract, and respiratory system. In this study, a database of Sb concentrations in the global atmosphere was developed through a survey of measurements published in more than 600 articles, which was then used to assess the health risks of Sb exposure based on a USEPA assessment model. Most measurements showed Sb concentrations of less than ∼10 ng m –3 , but those at several contaminated sites exhibited Sb concentrations of more than 100 ng m –3 . For measurements conducted in urban environments, Sb concentrations in the total suspended particles (TSP) and particles of less than 10 (PM 10 ) or 2.5 μm (PM 2.5 ) were the highest in Asia, followed by Europe, South America, and North America. Sb concentrations were generally higher in winter and fall than during other seasons in TSP and PM 10 samples. A significant correlation was observed between Sb and As in TSP and PM 2.5 on a global scale. Sb was mainly derived from anthropogenic sources, especially traffic emission, industrial emission, and fossil combustion. Hazard quotients (HQ) of Sb in TSP, PM 10 , and PM 2.5 were higher for children than adults because of their lighter body weight, inferior physical resistance, and higher ingestion probability. The global database for atmospheric Sb concentrations demonstrates a relatively low noncarcinogenic risk in most regions. Long-term monitoring is still required to identify the sources and growth potentials of Sb so that effective control policies can be established.

“…For the insoluble elements, the scavenging ratios were calculated by the above formulas and were subsequently bias-corrected by reducing the values by a factor of 2.6 for rain and 1.6 for snow (Cheng et al, 2021 Fine fraction (f) values were taken from the database of literature values (Mamun et al, 2020), unless otherwise indicated. b Fine fraction (f) values were taken from Mamun et al (2021).…”

“…Solid-phase metals have a residence time in the atmosphere that is inversely related to the size of the suspended particles (Mamun et al, 2020). Mercury (Hg) is the only metal with an important gaseous phase (Hg0) at the earth's normal atmospheric temperature and pressure, and this element can therefore reside in the atmosphere for periods varying between several months up to a year and a half (Driscoll et al, 2013;Holmes et al, 2010;Schroeder and Munthe, 1998).…”

“…The PM 2.5 /PM 10 designation is a frequently reported measure of size distribution of aerosols in the atmosphere. Metals from natural sources (released from crustal erosion and volcanoes) typically have a lower PM 2.5 /PM 10 ratio (coarser particulates) and therefore have a shorter residence time in the atmosphere compared to anthropogenic metals released by most industrial processes (Mamun et al, 2020). Atmospheric metals precipitate on land by dry deposition, i.e.…”

“…the coalescence of metals to rain and snow precipitation (Galloway et al, 1982). The dry deposition rate is typically higher for natural metals than anthropogenically released metals (Mamun et al, 2020). For example, in Greenland, the dry deposition typically contributes less than 25 % of the total anthropogenic contaminant deposition, with wet deposition covering the majority (>75%) of this flux (Davidson et al, 1981).…”

More details on the sources of funding are included in individual projects acknowledgment sections at the end of chapters three to six. An enormous thank you to the Department of Geography and Environmental Studies (DGES) atCarleton who not only funded my tuition, but also allowed me to be surrounded by exceptionally intelligent and talented people. The DGES holds some of the brightest researchers studying northern Canada and I am very proud to be part of the 2021 vintage of the DGES.Thanks to the many lab assistants who helped collect data for this thesis. The number of names in this paragraph is a demonstration that I am a cog in a much larger machine. The people I thank are
