Background contamination was limited by the sampler design, providing method quantification limits (MQLs) at least two orders of magnitude lower than other studies within the gas (MQL: 500 pg (\u03a3SCCPs), 1.86 ng (\u03a3MCCPs)) and particle (MQL: 500 pg (\u03a3SCCPs), 1.72 ng (\u03a3MCCPs) phases. Good repeatability was observed between parallel indoor measurements (RSD \u2264 9.3% (gas), RSD \u2264 14% (particle)) with no breakthrough\/saturation observed after a week of continuous sampling. For indoor air sampling, SCCPs were dominant within the gas phase (17 \u00b1 4.9 ng\/m3) compared to MCCPs (2.7 \u00b1 0.8 ng\/m3) while the opposite was observed in the particle bound fraction (0.28 \u00b1 0.11 ng\/m3 (\u03a3SCCPs) vs. 2.7 \u00b1 1.0 ng\/m3 (\u03a3MCCPs)). Only SCCPs in the gas phase could be detected reliably during outdoor sampling and were considerably lower compared to indoor concentrations (0.27 \u00b1 0.10 ng\/m3). Separation of the gas and particle bound phase was found to be crucial in applying the appropriate response factors for quantification based on the deconvoluted S\/MCCP sample profile, thus avoiding over- (gas phase) or underestimation (particle phase) of reported concentrations. Very short chain chlorinated paraffins (vSCCPs, C5-C9) were also detected at equal or higher abundance compared to SCCP congener groups (C10-C13) congener groups, indicating an additional human indoor inhalation risk.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 14:25:41","footnotes":""},"nva_tax_category":[1099],"class_list":["post-117058","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-scientific-journal-publication"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/117058","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\/117058\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=117058"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=117058"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
