Storicamente, l&#8217;industria si riferiva a queste sostanze come composti chimici perfluorurati o PFC. Tuttavia, poich\u00e9 questo acronimo si riferisce anche ai carboni perfluorurati, \u00e8 caduto in disuso come termine per i <strong>composti PFAS<\/strong>. Sebbene il perfluorottano sulfonato (PFOS) e l&#8217;<strong>acido perfluorottanoico (PFOA)<\/strong> siano le forme pi\u00f9 comunemente discusse, i <strong>PFAS<\/strong> costituiscono una classe incredibilmente ampia, che comprende molte migliaia di varianti.   <\/p><p>Cosa hanno in comune queste diverse sostanze? Tutti i <strong>composti PFAS<\/strong> contengono una catena di atomi di carbonio legati ad atomi di fluoro, ma il numero esatto di atomi varia a seconda della specifica sostanza chimica. Nelle sostanze perfluoroalchiliche, ad esempio, tutti i carboni tranne l&#8217;ultimo della catena sono legati ad atomi di fluoro. Per le <strong>sostanze polifluoroalchiliche<\/strong>, invece, almeno uno (ma non tutti) dei carboni della catena \u00e8 legato ad atomi di fluoro. Il numero di atomi di carbonio contenuti nella catena perfluorurata di un composto lo distingue come <strong>PFAS a catena lunga<\/strong> (sette o pi\u00f9 atomi di carbonio) o <strong>PFAS a catena corta<\/strong> (meno di sette atomi).[1]    <\/p><p>Un&#8217;altra caratteristica chiave dei <strong>PFAS<\/strong> \u00e8 che sono composti fluorurati <em>artificiali<\/em> che non si trovano naturalmente nell&#8217;ambiente. La loro produzione \u00e8 iniziata negli anni &#8217;40 per applicazioni prevalentemente industriali, come additivi per rivestimenti, ma il loro uso si \u00e8 presto esteso alle schiume antincendio e infine a oggetti di uso quotidiano come pentole antiaderenti e cosmetici. Con la crescente popolarit\u00e0 dei <strong>PFAS<\/strong>, sono aumentate le preoccupazioni relative al loro potenziale impatto sulle persone, sulla fauna selvatica e sul pianeta.  <\/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> Il problema dei PFAS nell&#8217;ambiente<\/h4>\n<p>I <strong>PFAS<\/strong> sono notoriamente stabili, e questo crea seri problemi per la salute pubblica quando sfuggono alle loro applicazioni previste. La loro estrema stabilit\u00e0 chimica e la bassa volatilit\u00e0 rendono i <strong>PFAS<\/strong> altamente <strong>persistenti nell&#8217;ambiente<\/strong> e mobili sia nell&#8217;atmosfera che nei principali corpi idrici. Di conseguenza, vengono soprannominati \u201c<strong>sostanze chimiche permanenti<\/strong>\u201d (forever chemicals); sostanze che non si degradano n\u00e9 restano facilmente confinate, accumulandosi negli ecosistemi e nei nostri corpi con risultati potenzialmente tossici.  <\/p>\n<p>I ricercatori hanno trovato prove convincenti che collegano le alte concentrazioni di <strong>PFAS<\/strong> nei corpi umani e animali a una variet\u00e0 di problemi di salute; dai problemi di sviluppo nei bambini alla compromissione della funzione endocrina e all&#8217;aumento del rischio di alcuni tumori.[2] In generale, i <strong>PFAS<\/strong> a <strong>catena lunga<\/strong> sono pi\u00f9 acutamente tossici, sebbene sia stato dimostrato che anche le varianti a catena corta causano cambiamenti cellulari potenzialmente dannosi.[3] L&#8217;eccessivo accumulo di <strong>PFAS<\/strong> nell&#8217;acqua, nell&#8217;aria e nel suolo pu\u00f2 avere effetti altrettanto dannosi sulla flora e sulla fauna che durano per decenni, se non di pi\u00f9.[4] In quest&#8217;ottica, i governi e le agenzie ambientali internazionali hanno introdotto costantemente restrizioni sulla produzione e sull&#8217;uso delle sostanze chimiche permanenti con l&#8217;obiettivo di rendere la societ\u00e0 <strong>priva di PFAS<\/strong>, e questa tendenza non mostra segni di rallentamento.   <\/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>Come considerano i PFAS le autorit\u00e0 di regolamentazione? <\/h4><p>Il <strong>PFOA<\/strong> e il PFOS sono stati inseriti nella <a href=\"https:\/\/www.pops.int\/TheConvention\/ThePOPs\/AllPOPs\/tabid\/2509\/Default.aspx\">Convenzione di Stoccolma sugli inquinanti organici persistenti<\/a> (POP) e, di conseguenza, sono soggetti a restrizioni ai sensi del <a href=\"https:\/\/eur-lex.europa.eu\/eli\/reg\/2019\/1021\/oj\/eng\">Regolamento UE sui POP<\/a>.
