Argyria
open-in-new
<h2 id="pathophysiology">Pathophysiology</h2> <p>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.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> As in <a href="/facts/Analog_photography/nL7SlGmc">analog photography</a> (where silver is used for its sensitivity to light), exposure of pale or colorless silver compounds to sunlight decomposes them to silver metal or <a href="/facts/Silver_sulfide/muzsPR6v">silver sulfides</a>. Commonly these products deposit as microscopic particles in the skin, in effect a dark pigment. This condition is known as argyria or argyrosis. </p><p>Chronic intake also may lead to silver pigments depositing in other organs exposed to light, particularly the <a href="/facts/Human_eye/a24ua4fy">eyes</a>.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> In the conjunctiva this is not generally harmful, but it also may affect the lens, leading to serious effects. </p><p>Localized argyria often results from <a href="/facts/Topical_medication/alFfLndS">topical</a> use of substances containing silver, such as some kinds of <a href="/facts/Eye_drop/TzKX8700">eye drops</a>. 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.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p><p>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 <a href="/facts/Oligodynamic_effect/uKE1lupq">oligodynamic effect</a>. Chronic ingestion or inhalation of silver preparations (especially <a href="/facts/Colloidal_silver/mDFrEyBx">colloidal silver</a>) can lead to argyria in the skin and other organs. This is not life-threatening but is considered by most to be cosmetically undesirable.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a><a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a><a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a><a class="footnote-ref" id="fnref:10" href="#fn:10"><sup>10</sup></a> </p><p>The <a href="/facts/Reference_dose/d00CKNxf">reference dose</a>, published by the <a href="/facts/United_States_Environmental_Protection_Agency/ghI985SI">United States Environmental Protection Agency</a> 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/(kg·d).<a class="footnote-ref" id="fnref:11" href="#fn:11"><sup>11</sup></a> </p><p>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. </p> <h2 id="history">History</h2> <p>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.<a class="footnote-ref" id="fnref:12" href="#fn:12"><sup>12</sup></a><a class="footnote-ref" id="fnref:13" href="#fn:13"><sup>13</sup></a> 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 <a href="/facts/Liquid/t9GkLWzt">liquid</a> <a href="/facts/Suspension_(chemistry)/S3xp96TL">suspension</a> of <a href="/facts/Microscopic/EHg18xvy">microscopic</a> silver particles, 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 <a href="/facts/Penicillin/Abo8VQ3p">penicillin</a>. </p> <h2 id="society-and-culture">Society and culture</h2> <p>A prominent case involving the ingestion of colloidal silver was that of American <a href="/facts/Stan_Jones_(Libertarian_politician)/psvluLF8">Stan Jones</a>, a <a href="/facts/Libertarian_Party_(United_States)/Wf4brzDk">Libertarian</a> candidate for the <a href="/facts/United_States_Senate/VyzXHE01">United States Senate</a> in 2002 and 2006.<a class="footnote-ref" id="fnref:14" href="#fn:14"><sup>14</sup></a><a class="footnote-ref" id="fnref:15" href="#fn:15"><sup>15</sup></a> 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".<a class="footnote-ref" id="fnref:16" href="#fn:16"><sup>16</sup></a> Jones promised that he was not using his silvery complexion as a gimmick. His purposeful consumption of <a href="/facts/Colloidal_silver/mDFrEyBx">colloidal silver</a> was a self-prescribed measure undertaken in response to fears that the <a href="/facts/Year_2000_problem/GQwkI92d">Y2K problem</a> would make antibiotics unavailable, an event that did not occur.<a class="footnote-ref" id="fnref:17" href="#fn:17"><sup>17</sup></a><a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> He is reported to have said that given the chance to go back, he would do it again.<a class="footnote-ref" id="fnref:19" href="#fn:19"><sup>19</sup></a> He maintains that his good health, except for the unusual skin tone, is the result of his use of colloidal silver.<a class="footnote-ref" id="fnref:20" href="#fn:20"><sup>20</sup></a> </p><p>In 2007, press reports described <a href="/facts/Paul_Karason/adLh0HkQ">Paul Karason</a>, an <a href="/facts/Americans/srd9GJ5U">American</a> man whose skin gradually turned <a href="/facts/Blue/DHWb8MUa">blue</a> after he took a homemade <a href="/facts/Silver_chloride/qSbcrlqq">silver chloride</a> colloid and used a silver salve on his face in an attempt to treat problems with his <a href="/facts/Paranasal_sinuses/ybG3rkBB">sinuses</a>, <a href="/facts/Dermatitis/JwlyQBa2">dermatitis</a>, <a href="/facts/Gastroesophageal_reflux_disease/8YhncnDz">acid reflux</a> and other issues.<a class="footnote-ref" id="fnref:21" href="#fn:21"><sup>21</sup></a><a class="footnote-ref" id="fnref:22" href="#fn:22"><sup>22</sup></a> At the time of the reports, Karason maintained his belief in silver's effectiveness and continued to take it, albeit in smaller doses. He died in 2013 of a <a href="/facts/Heart_attack/VnrWspaY">heart attack</a>; "a cause of death was not immediately known", but according to Jo Anna Karason, his estranged wife, "Paul Karason had suffered heart problems for years.
