Treatment plants do not remove all of the persistent chemical pollutants in wastewater from industry, so they often end up in rivers, streams and irrigation systems. Members of the genus Daphnia are not actually fleas but a group of more than 450 species of tiny crustaceans that filter feed, ingesting any small particles of detritus, algae or bacteria in their path.<\/p>\n<p>The scientists selected four types of water flea that consume some of the pollutants that worry public health professionals the most: the pharmaceutical compound diclofenac, the pesticide atrazine, the heavy metal arsenic and the industrial chemical PFOS, which is often used to make clothes waterproof.<\/p>\n<p>To find the fleas that would be best suited to tackle these pollutants Orsini resurrected some dormant embryos stuck in sediment at the bottom of rivers. Their embryos are encapsulated in a case that sinks to the bottom of lakes and waits for better conditions to hatch \u2013 but if that time does not come they can lie dormant for centuries. The fleas are self-sustaining as they reproduce by cloning and they self-regulate, growing or decreasing in population according to the nutrients available.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.theguardian.com\/environment\/2023\/sep\/26\/scientists-use-water-fleas-to-filter-pollutants-out-of-wastewater\">Guardian<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/5-409\/\">Scientists use water fleas to filter pollutants out of wastewater<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[575,2885,5838],"class_list":["post-117203","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-wastewater","tag-water-flea"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/117203","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=117203"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/117203\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=117203"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=117203"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=117203"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
