They have been found at the bottom of the oceans, at the tops of mountains, and in the air in our cities. Now, their presence has been confirmed in the world\u2019s largest rainforest. Researchers from the Federal University of S\u00e3o Paulo (UNIFESP) and the University of S\u00e3o Paulo (USP) found microplastics in the sediment of the Negro, Solim\u00f5es, and Amazonas rivers within 110 kilometers of Manaus, the capital city of the state of Amazonas, which has 2.2 million inhabitants and a modern industrial park. The highest concentrations\u2014ranging from 5,700 to 8,200 particles per kilogram (kg) of sediment\u2014were measured in the sand and mud of the Negro River near Manaus, where it converges with the Solim\u00f5es River. The researchers found intermediate quantities (1,200\u20131,700 particles\/kg) in the Solim\u00f5es River upstream of Manaus, possibly from other cities, such as Manacapuru. The smallest levels were observed in Amazonas, at 34 meters deep and 110 kilometers downstream from the capital (<em>Science of the Total Environment<\/em>, August 10). \u201cOur results show that we need to advance our knowledge about the sources and fates of microplastics, to infer how they impact ecosystems in the Amazon,\u201d wrote UNIFESP ecologist D\u00e9cio Semensatto and his colleagues.<\/p>\n","protected":false},"excerpt":{"rendered":"Researchers found microplastics in the sediment of the Negro, Solim\u00f5es, and Amazonas rivers ","protected":false},"author":475,"featured_media":381160,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[200],"coauthors":[785],"class_list":["post-381023","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-notes","tag-environment"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/381023","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=381023"}],"version-history":[{"count":2,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/381023\/revisions"}],"predecessor-version":[{"id":381611,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/381023\/revisions\/381611"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/381160"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=381023"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=381023"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=381023"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=381023"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
