Chronic exposure to CCs is a potential health risk given the toxicity of these chemicals. The present study reports on the measurement of the concentrations of 14 CCs in air as vapors and 2.5 \u00b5m fraction PM by the ENVINT GAS08\/16 gas\/aerosol sampler, a serial sampler that uses annular denuder, as sampling device. The 14 CCs were derivatized during sampling prior to gas-chromatographic separation and multiple detection by mass spectrometry, nitrogen-phosphorus thermionic, electron capture detection. Outdoor air multiple samples were collected in four locations in the urban area of Florence. The results evidenced that formaldehyde, acetaldehyde, and acetone were the more abundant CCs in the studied areas. The data collected was discussed considering the particle to vapor ratio of each CC found. The CCs pollution picture obtained was tentatively related to the nature and intensity of the traffic transiting by the sampling sites. This approach allowed to determine 14 CCs in both concentrated and diluted samples and is proposed as a tool for investigating outdoor and indoor pollution.<\/jats:p>","DOI":"10.3390\/ijerph16111969","type":"journal-article","created":{"date-parts":[[2019,6,3]],"date-time":"2019-06-03T11:31:01Z","timestamp":1559561461000},"page":"1969","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Monitoring of Air-Dispersed Formaldehyde and Carbonyl Compounds as Vapors and Adsorbed on Particulate Matter by Denuder-Filter Sampling and Gas Chromatographic Analysis"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3078-7188","authenticated-orcid":false,"given":"Stefano","family":"Dugheri","sequence":"first","affiliation":[{"name":"Industrial Hygiene and Toxicology Laboratory, Careggi University Hospital, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0579-1035","authenticated-orcid":false,"given":"Nicola","family":"Mucci","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Cappelli","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessandro","family":"Bonari","sequence":"additional","affiliation":[{"name":"General Laboratory, Careggi University Hospital, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giacomo","family":"Garzaro","sequence":"additional","affiliation":[{"name":"Department of Public Health Sciences and Pediatrics, University of Turin, 10126 Turin, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1399-5783","authenticated-orcid":false,"given":"Giorgio","family":"Marrubini","sequence":"additional","affiliation":[{"name":"Department of Drug Sciences, University of Pavia, 27100 Pavia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5631-8769","authenticated-orcid":false,"given":"Gianluca","family":"Bartolucci","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Psychology, Drug Research and Child Health Section of Pharmaceutical and Nutraceutical Sciences, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcello","family":"Campagna","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences and Public Health, University of Cagliari, 09124 Cagliari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giulio","family":"Arcangeli","sequence":"additional","affiliation":[{"name":"Department of Experimental and Clinical Medicine, University of Florence, 50134 Florence, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,6,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"709","DOI":"10.1080\/10473289.2006.10464485","article-title":"Health effects of fine particulate air pollution: Lines that connect","volume":"56","author":"Pope","year":"2006","journal-title":"J.
