It may take the form of ''generalized argyria'' or ''local argyria''. Generalized argyria affects large areas over much of the visible surface of the body. Local argyria shows in limited regions of the body, such as patches of skin, parts of the [[mucous membrane]], or the [[conjunctiva]]. The terms ''argyria'' and ''argyrosis'' have long been used interchangeably,<ref>Guttmann, Paul. tr. by A. Napier. A handbook of physical diagnosis comprising the throat, thorax, and abdomen. 1879. May be downloaded from https://archive.org/details/ahandbookphysic02guttgoog</ref> with ''argyria'' being used more frequently. ''Argyrosis'' has been used particularly in referring to argyria of the conjunctiva, but the usage has never been consistent and cannot be relied on except where it has been explicitly specified.<ref>Fox, Lawrance Webster. A practical treatise on ophthalmology. Pub. D. Appleton and company NY. 1920. May be downloaded from https://archive.org/details/apracticaltreat00foxgoog</ref> The term is from the {{langx|grc|į¼ĻĪ³Ļ ĻĪæĻ}} ({{Lang|grc-latn|argyros}}, 'silver'). ==Pathophysiology== In humans and other animals, chronic intake of silver products commonly leads to the gradual accumulation of silver compounds in various parts of the body.<ref name="FungBowen1996">{{cite journal |vauthors=Fung MC, Bowen DL |title=Silver products for medical indications: risk-benefit assessment |journal=Journal of Toxicology.

Commonly these products deposit as microscopic particles in the skin, in effect a dark pigment. This condition is known as argyria or argyrosis. Chronic intake also may lead to silver pigments depositing in other organs exposed to light, particularly the [[human eye|eyes]].<ref name="Lansdown2006">{{cite book |author=Lansdown AB |title=Biofunctional Textiles and the Skin |chapter=Silver in health care: antimicrobial effects and safety in use |volume=33 |pages=17ā34 |year=2006 |pmid=16766878 |doi=10.1159/000093928 |series=Current Problems in Dermatology |isbn=3-8055-8121-1}}</ref> In the conjunctiva this is not generally harmful, but it also may affect the lens, leading to serious effects. Localized argyria often results from [[Topical medication|topical]] use of substances containing silver, such as some kinds of [[eye drop]]s. Generalized argyria results from chronically swallowing or inhaling silver compounds, either for home medicinal purposes or as a result of working with silver or silver compounds.<ref name="pmid-16021155">{{cite journal |vauthors=Brandt D, Park B, Hoang M, Jacobe HT |title=Argyria secondary to ingestion of homemade silver solution |journal=Journal of the American Academy of Dermatology |volume=53 |issue=2 Suppl 1 |pages=S105ā7 |date=August 2005 |pmid=16021155 |doi=10.1016/j.jaad.2004.09.026}}</ref> While silver is potentially toxic to humans at high doses, the risk of serious harm from low doses, given over a short term, is small. Silver is used in some medical appliances because of its anti-microbial nature, which stems from the [[oligodynamic effect]]. Chronic ingestion or inhalation of silver preparations (especially [[colloidal silver]]) can lead to argyria in the skin and other organs. This is not life-threatening but is considered by most to be cosmetically undesirable.<ref name="FungBowen1996"/><ref name="Lansdown2006"/><ref>{{cite web | url=https://www.atsdr.cdc.gov/toxfaqs/tfacts146.pdf | title=ToxFAQsTM for Silver | date=July 1999 }}</ref><ref>{{cite web | url=https://www.atsdr.cdc.gov/toxprofiles/tp146-c1.pdf | title=Public Health Statement: Silver | publisher=ATSDR}}</ref> The [[reference dose]], published by the [[United States Environmental Protection Agency]] in 1991, which represents the estimated daily exposure that is unlikely to incur an appreciable risk of deleterious effects during a lifetime, is 5 μg/(kgĀ·d).<ref name="FungBowen1996"/> Argyria worsens and builds up as exposure to silver continues, and does not resolve once exposure stops because the silver atoms cannot be removed from the skin and other tissues. == History == Since at least the mid-19th century, doctors have known that silver or silver compounds can cause some areas of the skin and other body tissues to turn grey or blue-gray.<ref>{{cite book|title=London Medical Gazette: Or, Journal of Practical Medicine|url=https://books.google.com/books?id=eIQM_vME0QgC&pg=PA791|access-date=13 July 2013|year=1843|pages=791ā}}</ref><ref>{{cite book|title=The Cincinnati Lancet and Observer|url=https://books.google.com/books?id=B-QiAQAAMAAJ&pg=PA141|access-date=13 July 2013|year=1859|publisher=E.B. Stevens|pages=141ā}}</ref> Argyria occurs in people who ingest or inhale silver in large quantities over a long period (several months to many years). People who work in factories that manufacture silver products can also breathe in silver or its compounds. In the past, some of these workers have become argyric. However, the level of silver in the air and the length of exposure that caused argyria in these workers is not known. Historically, colloidal silver, a [[liquid]] [[suspension (chemistry)|suspension]] of [[microscopic]] silver particles,<!--A [[colloid]] is defined as particles which remain suspended without forming an [[Ionic liquid|ionic]] or dissolved solution.--> was also used as an internal medication to treat a variety of diseases. In the 1940s, they were overtaken by the use of pharmaceutical antibiotics, such as [[penicillin]]. ==Society and culture== [[File:Plata Coloidal Super Tyndall Effect.jpeg|thumb|Colloidal silver is illegally marketed as a medicine, but it is not proven to treat any condition, and may interfere with the functioning of some medications, such as antibiotics and thyroxine.<ref>{{cite web |title=Colloidal Silver |url=https://www.nccih.nih.gov/health/colloidal-silver |website=NCCIH |language=en}}</ref>]] A prominent case involving the ingestion of colloidal silver was that of American [[Stan Jones (Libertarian politician)|Stan Jones]], a [[Libertarian Party (United States)|Libertarian]] candidate for the [[United States Senate]] in 2002 and 2006.<ref name="Post">{{cite news|url=https://www.washingtonpost.com/archive/lifestyle/2006/11/12/a-true-blue-libertarian-span-classbankheadstan-jones-the-also-ran-who-changed-the-hue-of-politicsspan/f065de8d-16c0-47ef-8451-1a67c8291f80/|title=A True Blue Libertarian|author=[[Blaine Harden]]|newspaper=[[The Washington Post]]|date=November 12, 2006|accessdate=August 10, 2021}}</ref><ref name="Spoon">{{cite web|url=https://www.npr.org/templates/story/story.php?storyId=128588187|title=Fun And Intrigue With The Periodic Table|author=[[All Things Considered]]|publisher=[[National Public Radio]]|date=July 17, 2010|accessdate=August 10, 2021}}</ref> The peculiar coloration of his skin was featured prominently in media coverage of his unsuccessful campaign, though his supporters contended that the best-known photo was "doctored".<ref>{{Cite news |last=Sullivan |first=Robert |date=2002-11-03 |title=A Case of the Blues |url=https://www.newyorker.com/magazine/2002/11/11/a-case-of-the-blues |access-date=2024-01-07 |work=The New Yorker |language=en-US |issn=0028-792X}}</ref><!-- Unreliable source removed: <ref name="StanJonesLetter">{{cite web | last=Kotynski | first=Tom | title=Colloidal Silver News - Senate candidate sports a 'healthy' shade of blue | website=Colloidal Silver News, Generators, Facts and More | date=30 September 2002 | url=http://www.csfacts.com/pages/jones.html | access-date=13 December 2021}}</ref> --> Jones promised that he was not using his silvery complexion as a gimmick.
