This unusual property has led to the development of organofluorine compounds targeting specific needs in medicine, plastics, textiles, refrigeration and other areas. Some like the fluorocarbons also serve as ozone depletors and pollutants. ]]></LexicalValue></ScopeNote><NonPreferredTerm dc:identifier="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31373550" xml:lang="en">	<LexicalValue>fluorine organic compounds</LexicalValue>		<dcterms:created></dcterms:created>		<USE>http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31373549</USE></NonPreferredTerm><NonPreferredTerm dc:identifier="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31373551" xml:lang="en">	<LexicalValue>organofluorines</LexicalValue>		<dcterms:created></dcterms:created>		<USE>http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31373549</USE></NonPreferredTerm><HasHierRelConcept Role="BT">http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31343241</HasHierRelConcept></ThesaurusConcept></Thesaurus>
