Gonzalez, Minnesota Department of Transportation \/ Flickr<\/span><\/p><\/div>\n<p>Every year, the US spreads 44 million tons of salt\u201444% of the country\u2019s annual consumption\u2014on roads to melt ice, which increases the salinity of rivers near cities. This and other human activities, such as mining and agriculture, are accelerating the natural salt cycle and spreading salt into the air, soil, and rivers. As well as posing a risk to biodiversity and making it more difficult to obtain fresh drinking water, salt ions can generate harmful compounds when they bind to soil contaminants. A study led by Sujay Kaushal, a geologist from the University of Maryland, USA, concluded that an area roughly the size of the USA has been salinized over the last 50 years. \u201cIf you think of the planet as a living organism, accumulating so much salt could affect the functioning of vital organs or ecosystems,\u201d said Kaushal in a National Science Foundation (NSF) press release. \u201cRemoving salt from water is energy-intensive and expensive, and the brine byproduct you end up with is saltier than ocean water and can\u2019t be easily disposed of.\u201d (<em>Nature Reviews Earth &amp; Environment<\/em>, October 31, 2023; <em>NSF<\/em> <em>Newsletter<\/em>, January 4).<\/p>\n","protected":false},"excerpt":{"rendered":"Use of salt in mining, agriculture, and to melt ice on roads poses a risk to biodiversity","protected":false},"author":475,"featured_media":0,"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":[206,200],"coauthors":[785],"class_list":["post-515944","post","type-post","status-publish","format-standard","hentry","category-notes","tag-biodiversity","tag-environment"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/515944","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=515944"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/515944\/revisions"}],"predecessor-version":[{"id":515953,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/515944\/revisions\/515953"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=515944"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=515944"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=515944"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=515944"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
