Four alternatives for the smelter\u2019s production of aluminium were considered: 120,000 (ALT. 1), 240,000 (ALT. 2), 360,000 (ALT. 3) and 480,000 (ALT. 4) tons of aluminium per year. Long-term dispersion calculations were done for one year average SO2 and PM10 concentrations and 6 months average gaseous and total fluorides, during the growing season. Dispersion calculations were also executed for a typical day with high impact of the pollution from the smelter on the population, for SO2 and PM10, and on the vegetation, for gaseous fluorides.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 15:04:06","footnotes":""},"nva_tax_category":[1095],"class_list":["post-120754","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-report"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/120754","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication"}],"about":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/types\/nva_publication"}],"version-history":[{"count":0,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/120754\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=120754"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=120754"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
