produkten Metaller och näringsämnen redovisas halterna av grundämnen och oorganiska föreningar som framgår av Tabell 2. Även några grundämnen som inte är metaller ingår alltså i produkten. Grundämnen analyseras, med några få undantag, med avseende på sedimentets totala halt i enlighet med Internationella havsforskningsrådets rekommendationer. Analys av sedimentets totala halt av ett ämne innebär att även grundämnen hårt bundna till mineralpartiklar i sedimentet omfattas av analysen. Beroende på elementgruppernas olika kemiska och analytiska egenskaper används tre olika metoder för uppslutning och lakning. För flertalet grundämnen smälts sedimentprovet med LiBO2 (litiumborat) och löses därefter i 5 % HNO3 (salpetersyra). För Ag, Be, Co, Cs, Cu, Li, Pb, Sb, Sn, Ti och Zn sker lakning med en syrablandning av HF (vätefluorid), HClO4 (perklorsyra) och HNO3. As, Cd, Hg, S och Se lakas med 7 M HNO3 vilket motsvarar svensk standard (SIS). Metoden för syralakning av sedimentprovet enligt svensk standard är selektiv, vilket innebär att ämnen inert bundna i mineralpartiklar i sedimentet då inte kommer att ingå i analysen.","extent":{"spatial":{"crs":"http://www.opengis.net/def/crs/OGC/1.3/CRS84","bbox":[[8.790893505618152,54.84928775948088,23.576677371695123,65.97798172834055]]}},"links":[{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/items?f=application%2Fvnd.google-earth.kml%2Bxml","rel":"items","type":"application/vnd.google-earth.kml+xml","title":"metaller_naringsamnen items as application/vnd.google-earth.kml+xml"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/items?f=application%2Fgeo%2Bjson","rel":"items","type":"application/geo+json","title":"metaller_naringsamnen items as application/geo+json"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/items?f=application%2Fvnd.ogc.fg%2Bjson","rel":"items","type":"application/vnd.ogc.fg+json","title":"metaller_naringsamnen items as application/vnd.ogc.fg+json"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/items?f=application%2Fgml%2Bxml%3Bversion%3D3.2","rel":"items","type":"application/gml+xml;version=3.2","title":"metaller_naringsamnen items as application/gml+xml;version=3.2"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/items?f=text%2Fcsv","rel":"items","type":"text/csv","title":"metaller_naringsamnen items as text/csv"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/items?f=application%2Fjson","rel":"items","type":"application/json","title":"metaller_naringsamnen items as application/json"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/items?f=text%2Fhtml","rel":"items","type":"text/html","title":"metaller_naringsamnen items as text/html"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen?f=text%2Fhtml","rel":"alternate","type":"text/html","title":"This document as text/html"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen?f=application%2Fjson","rel":"self","type":"application/json","title":"This document"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen?f=application%2Fx-yaml","rel":"alternate","type":"application/x-yaml","title":"This document as application/x-yaml"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/wfs?version=2.0&request=DescribeFeatureType&typenames=metaller_naringsamnen&service=WFS","rel":"describedBy","type":"application/xml","title":"Schema for metaller_naringsamnen"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/queryables?f=application%2Fschema%2Bjson","rel":"http://www.opengis.net/def/rel/ogc/1.0/queryables","type":"application/schema+json","title":"Queryable attributes as application/schema+json"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/queryables?f=text%2Fhtml","rel":"http://www.opengis.net/def/rel/ogc/1.0/queryables","type":"text/html","title":"Queryable attributes as text/html"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/queryables?f=application%2Fjson","rel":"http://www.opengis.net/def/rel/ogc/1.0/queryables","type":"application/json","title":"Queryable attributes as application/json"},{"href":"https://api.sgu.se/oppnadata/marina-sedimentprov/ogc/features/v1/collections/metaller_naringsamnen/queryables?f=application%2Fx-yaml","rel":"http://www.opengis.net/def/rel/ogc/1.0/queryables","type":"application/x-yaml","title":"Queryable attributes as application/x-yaml"}],"crs":["#/crs"],"storageCrs":"http://www.opengis.net/def/crs/EPSG/0/3006"},{"id":"organiska_miljogifter","title":"Organiska miljögifter","description":"De organiska föreningar vars halter redovisas i produkten framgår av Tabell 1.
