Snow photochemistry therefore affects the formation of ozone, a potent greenhouse gas, and of aerosols, which affect the radiative budget of the planet and, therefore, its climate. In parallel, microbiologists have investigated microbes in snow, identified and quantified species, and sometimes discussed their nutrient supplies and metabolism, implicitly acknowledging that microbes could modify snow chemical composition. However, it is only in the past 10 years that a small number of studies have revealed that microbial activity in cold snow (&lt; 0 \u00b0C, in the absence of significant amounts of liquid water) could lead to the release of nitrogen oxides, halocarbons, and mercury into the atmosphere. I argue here that microbes may have a significant effect on snow and atmospheric composition, especially during the polar night when photochemistry is shut off. Collaborative studies between microbiologists and snow and atmospheric chemists are needed to investigate this little-explored field.<\/jats:p>","DOI":"10.3390\/microorganisms7080260","type":"journal-article","created":{"date-parts":[[2019,8,15]],"date-time":"2019-08-15T04:22:54Z","timestamp":1565842974000},"page":"260","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Should We Not Further Study the Impact of Microbial Activity on Snow and Polar Atmospheric Chemistry?"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6438-6879","authenticated-orcid":false,"given":"Florent","family":"Domine","sequence":"first","affiliation":[{"name":"Takuvik Joint International Laboratory, Universit\u00e9 Laval (Canada) and CNRS-INSU (France), Qu\u00e9bec, QC G1V 0A6, Canada"},{"name":"Centre d\u2019\u00c9tudes Nordiques (CEN), Department of Chemistry and Department of Geography, Universit\u00e9 Laval, Qu\u00e9bec, QC G1V 0A6, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"4514","DOI":"10.1128\/AEM.66.10.4514-4517.2000","article-title":"Bacterial activity in South Pole snow","volume":"66","author":"Carpenter","year":"2000","journal-title":"Appl.
