Hist\u00f3ricamente, la industria se refer\u00eda a estos productos qu\u00edmicos como compuestos perfluorados o PFC. Sin embargo, dado que este acr\u00f3nimo tambi\u00e9n se refiere a los carbonos perfluorados, ha ca\u00eddo en desuso como t\u00e9rmino para los <strong>compuestos PFAS<\/strong>. Aunque el perfluorooctano sulfonato (PFOS) y el <strong>\u00e1cido perfluorooctanoico (PFOA)<\/strong> son las formas m\u00e1s com\u00fanmente discutidas, las <strong>PFAS<\/strong> son una clase incre\u00edblemente amplia, que abarca muchos miles de variedades.   <\/p>\n<p>Entonces, \u00bfqu\u00e9 tienen en com\u00fan estas diversas sustancias? Todos los <strong>compuestos PFAS<\/strong> contienen una cadena de \u00e1tomos de carbono unidos a \u00e1tomos de fl\u00faor, pero el n\u00famero exacto de \u00e1tomos var\u00eda seg\u00fan el producto qu\u00edmico espec\u00edfico. En las sustancias perfluoroalquiladas, por ejemplo, todos los carbonos, excepto el \u00faltimo de la cadena, est\u00e1n unidos a \u00e1tomos de fl\u00faor. En el caso de las <strong>sustancias polifluoroalquiladas<\/strong>, por otro lado, al menos uno (pero no todos) de los carbonos de la cadena est\u00e1n unidos a \u00e1tomos de fl\u00faor. El n\u00famero de \u00e1tomos de carbono contenidos en la cadena perfluorada de un compuesto lo distingue como <strong>PFAS de cadena larga<\/strong> (siete o m\u00e1s \u00e1tomos de carbono) o <strong>PFAS de cadena corta<\/strong> (menos de siete \u00e1tomos).[1]    <\/p>\n<p>Otra caracter\u00edstica clave de las <strong>PFAS<\/strong> es que son compuestos fluorados <em>artificiales<\/em> que no se encuentran de forma natural en el medio ambiente. Su producci\u00f3n comenz\u00f3 en la d\u00e9cada de 1940 para aplicaciones principalmente industriales, como aditivos para recubrimientos, pero su uso pronto se expandi\u00f3 a espumas contra incendios y, finalmente, a art\u00edculos cotidianos como utensilios de cocina antiadherentes y cosm\u00e9ticos. A medida que las <strong>PFAS<\/strong> se hicieron m\u00e1s populares, crecieron las preocupaciones en torno a su impacto potencial en las personas, la vida silvestre y el planeta.  <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4ab1bb9 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"4ab1bb9\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6f0badc elementor-widget elementor-widget-text-editor\" data-id=\"6f0badc\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4> El problema de las PFAS en el medio ambiente<\/h4>\n<p>Las <strong>PFAS<\/strong> son famosamente estables, y eso crea serios problemas para la salud p\u00fablica cuando escapan de sus aplicaciones previstas. Su extrema estabilidad qu\u00edmica y baja volatilidad hacen que las <strong>PFAS<\/strong> sean altamente <strong>persistentes en el medio ambiente<\/strong> y m\u00f3viles tanto en la atm\u00f3sfera como en las principales masas de agua. Como resultado, se las denomina \u00ab<strong>sustancias qu\u00edmicas eternas<\/strong>\u00bb; sustancias que no se descomponen ni se contienen f\u00e1cilmente, acumul\u00e1ndose en los ecosistemas y en nuestros cuerpos con resultados potencialmente t\u00f3xicos.  <\/p>\n<p>Los investigadores han encontrado pruebas convincentes que vinculan las altas concentraciones de <strong>PFAS<\/strong> en cuerpos humanos y animales con una variedad de problemas de salud; desde problemas de desarrollo en ni\u00f1os hasta una funci\u00f3n endocrina deteriorada y un mayor riesgo de ciertos tipos de c\u00e1ncer.[2] En general, las <strong>PFAS<\/strong> de <strong>cadena larga<\/strong> son m\u00e1s t\u00f3xicas, aunque las variedades de cadena corta tambi\u00e9n han demostrado causar cambios celulares potencialmente da\u00f1inos.[3] La sobreacumulaci\u00f3n de <strong>PFAS<\/strong> en el agua, el aire y el suelo puede tener efectos igualmente da\u00f1inos en la flora y la fauna que duran d\u00e9cadas, si no m\u00e1s.[4] Con esto en mente, los gobiernos y las agencias ambientales internacionales han estado introduciendo constantemente restricciones a la producci\u00f3n y el uso de sustancias qu\u00edmicas eternas con el objetivo de que la sociedad est\u00e9 finalmente <strong>libre de PFAS<\/strong>, y esta tendencia no muestra signos de desaceleraci\u00f3n.   <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-aa9a7f5 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"aa9a7f5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6d3b5bb elementor-widget elementor-widget-text-editor\" data-id=\"6d3b5bb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4>\u00bfC\u00f3mo ven las PFAS los reguladores? <\/h4><p>El <strong>PFOA<\/strong> y el PFOS fueron incluidos en el <a href=\"https:\/\/www.pops.int\/TheConvention\/ThePOPs\/AllPOPs\/tabid\/2509\/Default.aspx\">Convenio de Estocolmo sobre Contaminantes Org\u00e1nicos Persistentes<\/a> (COP) y, en consecuencia, est\u00e1n restringidos por el <a href=\"https:\/\/eur-lex.europa.eu\/eli\/reg\/2019\/1021\/oj\/eng\">Reglamento de la UE sobre COP<\/a>.
