The UNR-RMAS 2.0 provides a solution that will advance knowledge. From 11\/2017 to 02\/2019, the RMAS 2.0 was deployed in Hawai\u2019i, Nevada, Maryland, and Utah to test system performance and develop an understanding of RM at locations impacted by different atmospheric oxidants. Mauna Loa Observatory, Hawai\u2019i, impacted by the free troposphere and the marine boundary layer, had primarily \u2212Br\/Cl RM compounds. The Nevada location, directly adjacent to a major interstate highway and experiences inputs from the free troposphere, exhibited \u2212Br\/Cl, \u2212N, \u2212S, and organic compounds. In Maryland, compounds observed were \u2212N, \u2212S, and organic-Hg. This site is downwind of coal-fired power plants and located in a forested area. The location in Utah is in a basin impacted by oil and natural gas extraction, multiday wintertime inversion episodes, and inputs from the free troposphere. Compounds were \u2212Br\/Cl or \u2212O, \u2212N, and \u2212Br\/Cl. The chemical forms of RM identified were consistent with the air source areas, predominant ion chemistry, criterion air pollutants, and meteorology.<\/jats:p>","DOI":"10.1021\/acs.est.0c02283","type":"journal-article","created":{"date-parts":[[2020,6,8]],"date-time":"2020-06-08T00:08:00Z","timestamp":1591574880000},"page":"7922-7931","source":"Crossref","is-referenced-by-count":28,"title":["Use\nof Multiple Lines of Evidence to Understand Reactive\nMercury Concentrations and Chemistry in Hawai\u2019i, Nevada, Maryland,\nand Utah, USA"],"prefix":"10.1021","volume":"54","author":[{"given":"Adriel","family":"Luippold","sequence":"first","affiliation":[{"name":"University of Nevada , , , ,","place":["Reno, Nevada, United States, 89557"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9306-2037","authenticated-orcid":true,"given":"Mae Sexauer","family":"Gustin","sequence":"additional","affiliation":[{"name":"University of Nevada , , , ,","place":["Reno, Nevada, United States, 89557"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarrah M.","family":"Dunham-Cheatham","sequence":"additional","affiliation":[{"name":"University of Nevada , , , ,","place":["Reno, Nevada, United States, 89557"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Castro","sequence":"additional","affiliation":[{"name":"University of Maryland Center for Environmental Science , , , ,","place":["Frostburg, Maryland, United States, 21532"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Winston","family":"Luke","sequence":"additional","affiliation":[{"name":"National Oceanic and Atmospheric Administration , , , ,","place":["College\nPark, Maryland, United States, 20740"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seth","family":"Lyman","sequence":"additional","affiliation":[{"name":"Utah State University , , , ,","place":["Vernal, Utah, United States, 84322"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2796-6043","authenticated-orcid":true,"given":"Lei","family":"Zhang","sequence":"additional","affiliation":[{"name":"Nanjing University , , , ,","place":["Nanjing, Jiangsu, China, 210023"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2020,6,8]]},"reference":[{"key":"2026081417183191400_cit1","doi-asserted-by":"publisher","first-page":"3760","DOI":"10.1021\/cr500667e","article-title":"Mercury Physicochemical\nand Biogeochemical Transformation\nin the Atmosphere and at Atmospheric Interfaces: A Review and Future\nDirections","volume":"115","author":"Ariya","year":"2015","journal-title":"Chem.
