Present in PVC and certain textiles, these chemicals could also circulate through fertilizers derived from wastewater treatment plants. A finding that reopens concerns about invisible substances.<\/strong><\/p>\n<figure class=\"wp-block-image size-large\"><\/figure>\n<h2 class=\"wp-block-heading\">Researchers Detect a New Persistent Pollutant in the American Agricultural Air<\/h2>\n<p>In an agricultural region of Oklahoma, American researchers were simply monitoring the make\u2011up of <strong>atmospheric aerosols<\/strong>. Nothing suggested a major finding. Yet, amid the measurements, an unusual chemical signal appeared. A quiet presence, almost routine, but strange enough to trigger a deeper analysis.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">Beyond 20\u00b0C, pregnancies yield fewer boys, according to a large Oxford University study<\/span><\/section>\n<p>Using an advanced mass spectrometry technique, scientists identified <strong>Medium-Chain Chlorinated Paraffins<\/strong> <strong>(MCCP)<\/strong>. These substances are already used in certain textiles, industrial fluids, and PVC. Their presence in North American air had, until now, been little documented.<\/p>\n<p>Published in the scientific journal <strong>ACS Environmental Au<\/strong>, the discovery raises as many questions as it does concerns. MCCPs belong to the family of persistent pollutants capable of surviving long periods in the environment. Once released, these molecules can circulate between air, water, and soils for years.<\/p>\n<h2 class=\"wp-block-heading\">Agricultural Sewage Sludge Could Release These Substances into the Air<\/h2>\n<p>The trajectory of MCCP reads like a silent supply chain. After their use in industry, these substances enter wastewater. A portion ends up trapped in the <strong>biosolids<\/strong> from wastewater treatment plants. These residues, called <strong>agricultural biosolids<\/strong>, are then used as fertilizer on some farms.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">When neighbors go solar, fixed electricity network costs can weigh more on your bill<\/span><\/section>\n<p>Under the influence of sunlight, wind, or still poorly understood chemical reactions, the <strong>MCCP<\/strong> could subsequently be released into the atmosphere. This hypothesis remains to be confirmed, but it would explain the presence of these compounds in rural areas far from major industrial sites.<\/p>\n<p>Their behavior concerns toxicologists in particular. MCCP degrade extremely slowly in the environment and can remain present for long periods in soils or water. Several scientific studies already point to risks tied to <strong>liver toxicity<\/strong>, some kidney damage, and hormonal disruptions that are still not well characterized in humans.<\/p>\n<h2 class=\"wp-block-heading\">These New Pollutants Share Several Alarming Traits with PFAS<\/h2>\n<p>The term \u201c<strong>persistent pollutant<\/strong>\u201d immediately evokes PFAS, which have become one of the most visible symbols of global chemical contamination. Yet MCCP have a different structure. PFAS rely on a highly resistant carbon\u2013fluorine bond that is nearly impossible to break down in nature.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">When a tree dies, its roots show how carbon keeps circulating under a thriving, connected forest<\/span><\/section>\n<p>Instead, MCCP belong to the family of <strong>chlorinated paraffins<\/strong>. Their stability remains striking and their ability to travel through the environment strongly intrigues researchers. Traces of these substances have already been detected in Asia, Antarctica, and now North America.<\/p>\n<h2 class=\"wp-block-heading\">After SCCP and MCCP, Other Chemicals Are Already Under Watch<\/h2>\n<p>MCCP are not the first members of this family to draw the attention of health authorities. In 2017, <strong>SCCP<\/strong>, short-chain chlorinated paraffins, were listed on the <strong>Stockholm Convention<\/strong> blacklist. Since 2025, MCCP have likewise faced growing restrictions in Europe and in several industrialized countries.<\/p>\n<p>This sequence of bans already raises another question. What will become of the <strong>LCCP<\/strong>, long-chain chlorinated paraffins still used in some heavy plastics and flame\u2011retardant materials? For the moment, these substances remain <strong>permitted in several industrial sectors<\/strong>, even as regulatory pressure begins to tighten.<\/p>\n<section class=\"incontent-related\"><span class=\"incontent-related__title\">Read also<\/span> <span class=\"incontent-related__desc\">In the South Pacific, massive traces of zinc linked to human activity worry oceanographers<\/span><\/section>\n<p>The recent history of PFAS shows how much these discoveries can reshape environmental debates. This enormous chemical family comprises more than <strong>10,000 different molecules<\/strong>, some of which continue to circulate in everyday products. As scientific tools advance, more invisible pollutants emerge in the air, soils, or water.<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":1042,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[1356,621,1346,1355,1357,1353,1354],"class_list":["post-1041","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","tag-agricultural","tag-air","tag-chemicals","tag-contaminate","tag-fertilizers","tag-pvc","tag-textile","generate-columns","tablet-grid-50","mobile-grid-100","grid-parent","grid-50"],"_links":{"self":[{"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/posts\/1041","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/comments?post=1041"}],"version-history":[{"count":1,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/posts\/1041\/revisions"}],"predecessor-version":[{"id":1043,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/posts\/1041\/revisions\/1043"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/media\/1042"}],"wp:attachment":[{"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/media?parent=1041"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/categories?post=1041"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.farmersforum.ie\/trends\/wp-json\/wp\/v2\/tags?post=1041"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
