Results from Screening Campaign."},"content":{"rendered":"<p class=\"wp-block-paragraph\">This report presents the results from a screening study of volatile organic compounds (VOCs) in the Quintero-Puchuncav\u00ed<br \/>\nregion (Chile). Two different methods were selected, one quantitative (canisters samplers \/ analysis by Medusa\/GC-MS) and a second semi-quantitative (Tenax TA\/analysis by GC-MS). NILU evaluated the results of 4 compounds (methyl chloroform,<br \/>\nnitrobenzene, iso-butane and toluene), which were previously reported at very high concentrations and intensively<br \/>\ndiscussed in the media. NILU\u2019s measurement results show much lower concentrations and it was concluded that the former<br \/>\nmeasurements were done with a significant error in the calibration. The average concentration of ambient benzene was 1.0 \u00b5g\/m3 at industrial areas and 0.3 \u00b5g\/m3 at the residential\/background areas, both lower than international limit values. The main compounds emitted from the industrial areas are light hydrocarbons, which were detected at low concentration levels.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 13:51:50","footnotes":""},"nva_tax_category":[1095],"class_list":["post-113548","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\/113548","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\/113548\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=113548"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=113548"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
