Volatile organic compounds (VOCs) are widely used as fuels, in the production of plastics, as solvents and paint thinners. Their emissions contribute to air pollution directly or in chemical reactions which form secondary pollutants such as ozone.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31343241"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14085116"> <skos:prefLabel xml:lang="es">volatile organic compounds (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9847572"> <skos:prefLabel xml:lang="ca">volatile organic compounds (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:40:44</dct:created>  </skos:Concept></rdf:RDF>
