Now, results in ACS&#8217; Environmental Science &amp; Technology show that the contamination produced by detonation depends on the blast type, with weaker explosions leaving behind more potentially toxic residues.<\/p>\n<p>The researchers &#8212; working in close collaboration with the Royal Danish Navy &#8212; first identified World War II mines near a busy shipping route off the coast of Denmark, choosing the sites of two intact and two corroded devices. Divers from the Navy collected ocean water and ocean floor sediment around the mines, and researchers then used mass spectrometry to measure the samples&#8217; levels of TNT. As the researchers expected, chemical contamination was higher near the corroded mines than the intact ones.<\/p>\n<p>Sediment contained up to 100 million times more TNT after the weaker explosion than before, and only 250 times more TNT after the stronger blast. Similarly, the TNT levels in water after the weaker blast far exceeded those around the stronger one. The researchers say that the pollution released by the low-power blast meets or exceeds levels previously reported to be toxic to microalgae, sea urchins and fish. Because of the potential threats to nearby marine life, the researchers encourage less invasive methods to remediate submerged World War II relics &#8212; like robotic techniques to open and remove abandoned mines&#8217; explosive contents &#8212; to prevent unwanted explosions and contamination.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.sciencedaily.com\/releases\/2023\/11\/231129142305.htm\">Science Daily<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/4-440\/\">Blasts to clear World War II munitions could contaminate the ocean<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>","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":[575,5540,12459,12460],"class_list":["post-119063","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-explosion","tag-munition","tag-world-war-ii"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/119063","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/comments?post=119063"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/posts\/119063\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/media?parent=119063"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/categories?post=119063"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/en\/wp-json\/wp\/v2\/tags?post=119063"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
