Editing Arsenic (section)

=== Exposure risks and remediation ===

Occupational exposure and [[arsenic poisoning]] may occur in people working in industries involving the use of inorganic arsenic and its compounds, such as wood preservation, glass production, nonferrous metal alloys, and electronic semiconductor manufacturing. Inorganic arsenic is also found in coke oven emissions associated with the smelter industry.<ref>{{cite web

The conversion between As(III) and As(V) is a large factor in arsenic environmental contamination. According to Croal, Gralnick, Malasarn and Newman, "[the] understanding [of] what stimulates As(III) oxidation and/or limits As(V) reduction is relevant for [[bioremediation]] of contaminated sites (Croal). The study of chemolithoautotrophic As(III) oxidizers and the heterotrophic As(V) reducers can help the understanding of the oxidation and/or reduction of arsenic.<ref>{{cite journal |title=The Genetics of Geochemisty |journal=Annual Review of Genetics |volume=38 |date=2004 |pages=175–206 |pmid=15568975 |doi=10.1146/annurev.genet.38.072902.091138 |last1=Croal |first1=Laura R. |last2=Gralnick |first2=Jeffrey A. |last3=Malasarn |first3=Davin |last4=Newman |first4=Dianne K. |url=http://authors.library.caltech.edu/286/ |access-date=30 August 2017 |archive-date=18 September 2021 |archive-url=https://web.archive.org/web/20210918094902/http://authors.library.caltech.edu/286/ |url-status=dead }}</ref>
