Milhões de pessoas no mundo inteiro adoecem e morrem sem saber que a causa de suas doenças é o envenenamento crônico por arsênio. Em <a href="/wiki/Bangladesh" title="Bangladesh">Bangladesh</a>, por exemplo, ocorreu uma intoxicação em massa, a maior da história, devido à construção de milhares de poços tubulares de água que estavam naturalmente contaminados com arsênio. A Organização Mundial de Saúde estabelece um limite máximo de 0,010 mg/L de arsênio em água para consumo humano (WHO, 2001). </p> <div class="mw-heading mw-heading3"><h3 id="O_arsênico"><span id="O_ars.C3.AAnico"></span>O arsênico</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ars%C3%AAnio&veaction=edit&section=8" title="Editar secção: O arsênico" class="mw-editsection-visualeditor"><span>editar</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ars%C3%AAnio&action=edit&section=8" title="Editar código-fonte da secção: O arsênico"><span>editar código-fonte</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="hatnote"><span typeof="mw:File"><span><img alt="" src="//upload.wikimedia.org/wikipedia/commons/thumb/3/3a/Magnifying_glass_01.svg/17px-Magnifying_glass_01.svg.png" decoding="async" width="17" height="17" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/3/3a/Magnifying_glass_01.svg/26px-Magnifying_glass_01.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/3/3a/Magnifying_glass_01.svg/34px-Magnifying_glass_01.svg.png 2x" data-file-width="663" data-file-height="659" /></span></span>Ver artigo principal: <a href="/wiki/Tri%C3%B3xido_de_ars%C3%AAnio" title="Trióxido de arsênio">Trióxido de arsênio</a></div> <p>"O elemento químico se chama arsênio, enquanto <b>arsênico</b>, talvez o mais famoso dos venenos, é o nome popular de um de seus compostos, o trióxido de arsênio — também conhecido como arsênico branco".<sup id="cite_ref-:0_1-1" class="reference"><a href="#cite_note-:0-1"><span>[</span>1<span>]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Toxicologia">Toxicologia</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Ars%C3%AAnio&veaction=edit&section=9" title="Editar secção: Toxicologia" class="mw-editsection-visualeditor"><span>editar</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Ars%C3%AAnio&action=edit&section=9" title="Editar código-fonte da secção: Toxicologia"><span>editar código-fonte</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>O arsênio é absorvido pelo organismo humano principalmente por inalação e ingestão. Os compostos orgânicos de arsênio são menos tóxicos que os inorgânicos. O arsênio inorgânico trivalente (As<sup>3+</sup>) interage fortemente com grupos <a href="/wiki/Tiol" title="Tiol">sulfidrilas</a> de moléculas orgânicas. Diversas enzimas são afetadas com isso, ocasionando danos em vários sistemas celulares. Basta uma dose de 140 miligramas de arsênio inorgânico trivalente para causar a morte de um ser humano adulto por dano à respiração celular, em poucas horas ou dias. O arsênio pode induzir a produção de metalotioneína, uma proteína que se liga a esse metal e também ao cádmio, mercúrio e a muitos metais essenciais. Supõem-se que esse é um dos mecanismos de adaptação que leva a uma relativa tolerância à toxicidade do arsênio em organismos multicelulares. A tolerância é dita relativa porque o acúmulo de arsênio no organismo causa doenças a médio e longo prazo, principalmente em espécies caracterizadas por alta duração de vida e alto índice de <a href="/wiki/Encefaliza%C3%A7%C3%A3o" class="mw-redirect" title="Encefalização">encefalização</a>, como a espécie humana. Os alimentos mais contem arsênio orgânico são peixes e crustáceos, apresentando-o geralmente na forma de arsenobetaína. </p> <h2 id="Referências" style="cursor: help;" title="Esta seção foi configurada para não ser editável diretamente.
