With this in mind, in the last 10 years, the demand for pellets in Italy has more than doubled, making Italy the second largest consumer in Europe. The quality of the pellets burned in stoves is crucial to indoor and outdoor pollution. Among other parameters, moisture and ash are used to classify pellets according to EN ISO 17225:2014. This work involved the analysis of the organic and inorganic fraction of both some finished products on the Italian market and some raw materials (e.g., wood chips) sampled according to the technical standard EN 14778:2011. The analytical results showed the presence of some substances potentially harmful to human health such as formaldehyde, acetone, toluene and styrene for the organic fraction and nickel, lead and vanadium for the inorganic fraction. The chemometric approach showed that it is the inorganic fraction which is most responsible for the diversification of the samples under study. The detection of some substances may be a warning bell about the impact of such materials, both for the environment and for human health.<\/jats:p>","DOI":"10.3390\/ijerph20166559","type":"journal-article","created":{"date-parts":[[2023,8,11]],"date-time":"2023-08-11T12:10:23Z","timestamp":1691755823000},"page":"6559","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Characteristics of Commercial and Raw Pellets Available on the Italian Market: Study of Organic and Inorganic Fraction and Related Chemometric Approach"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9745-1355","authenticated-orcid":false,"given":"Pietro","family":"Pandolfi","sequence":"first","affiliation":[{"name":"Department of Biomedicine and Prevention, University of Rome, Tor Vergata, 00155 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivan","family":"Notardonato","sequence":"additional","affiliation":[{"name":"Department of Agricultural, Environmental and Food Sciences (DiAAA), University of Molise, 86100 Campobasso, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergio","family":"Passarella","sequence":"additional","affiliation":[{"name":"Department of Agricultural, Environmental and Food Sciences (DiAAA), University of Molise, 86100 Campobasso, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5780-4400","authenticated-orcid":false,"given":"Maria Pia","family":"Sammartino","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Rome \u201cLa Sapienza\u201d, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giovanni","family":"Visco","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Rome \u201cLa Sapienza\u201d, 00185 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2078-0887","authenticated-orcid":false,"given":"Paolo","family":"Ceci","sequence":"additional","affiliation":[{"name":"Institute of Atmospheric Pollution Research, Division of Rome, c\/o Ministry of Environment and Energy Security, 00147 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Loretta","family":"De Giorgi","sequence":"additional","affiliation":[{"name":"Institute of Atmospheric Pollution Research, Division of Rome, c\/o Ministry of Environment and Energy Security, 00147 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7153-6919","authenticated-orcid":false,"given":"Virgilio","family":"Stillittano","sequence":"additional","affiliation":[{"name":"Istituto Zooprofilattico Sperimentale del Lazio e della Toscana \u201cM.
