Public Health"],"abstract":"<jats:p>The research study aimed at providing an accurate low-dose benzene exposure assessment method, by validating diffusive monitoring techniques for benzene personal exposure measurements at workplaces where benzene concentrations are expected in the low ppb range, such as in the present-day chemical, petrochemical, foundry, and pharmaceutical industry. The project was aimed at addressing the need for a robust and fully validated method to perform personal exposure measurements considering that the occupational exposure limit value for benzene is going to be significantly lowered in the next few years. Diffusive sampling offers a reliable alternative to pumped sampling methods, intrinsic safety in potentially explosive atmospheres, lightness, and ease of use. In this study, the <jats:italic>radiello<\/jats:italic>\u00ae diffusive sampler, with the packed activated charcoal RAD130 adsorbing substrate [suitable for solvent desorption and analysis by high-resolution gas chromatography-flame ionization detection (HRGC-FID)], was used. The experiments have been conducted following the ISO 23320 standard in the range from 0.005 to 0.1\u2009ppm (16 to 320\u2009\u03bcg\/m<jats:sup>3<\/jats:sup>), yielding a full validation of the sampling and analytical method. The sampler performances have fulfilled all requisites of the ISO 23320 standard, in particular: bias due to the selection of a non-ideal sorbent is lower than 10% (no significant back diffusion of benzene due to concentration change in the atmosphere); bias due to storage of samples for up to 2\u2009months is lower than 10%; nominal uptake rate for benzene on RAD130 is 74.65\u2009mL\/min; and expanded uncertainty of the sampling and analytical method is 20.6%. The sampling and analytical method is therefore fit-for-purpose for the personal exposure measurements aimed at testing compliance with occupational exposure limit values for benzene. The method is also fit for short-duration exposure monitoring related to specific tasks, and other volatile organic compounds, usually found in the same workplaces, such as aliphatic and aromatic hydrocarbons and some oxygenated compounds, have also been studied. In particular, n-hexane and isopropyl benzene, whose classification is currently under revision, can be efficiently monitored by this technique.<\/jats:p>","DOI":"10.3389\/fpubh.2023.1271550","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T15:26:02Z","timestamp":1699889162000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Accurate low-dose exposure assessment of benzene and monoaromatic compounds by diffusive sampling: sampling and analytical method validation according to ISO 23320 for radiello\u00ae samplers packed with activated charcoal"],"prefix":"10.3389","volume":"11","author":[{"given":"Laura","family":"Zaratin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caterina","family":"Boaretto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riccardo Carnevale","family":"Schianca","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Hinkal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elena","family":"Grignani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danilo","family":"Cottica","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,11,13]]},"reference":[{"key":"ref1","year":"1998"},{"key":"ref2","year":"2004"},{"key":"ref3","year":"2018"},{"key":"ref4","unstructured":"2019"},{"key":"ref5","year":"2022"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"78","DOI":"10.1016\/j.toxlet.2020.09.005","article-title":"Modes of action considerations in threshold expectations for health effects of benzene","volume":"334","author":"North","year":"2020","journal-title":"Toxicol Lett"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"117","DOI":"10.1016\/j.toxlet.2020.05.036","article-title":"Derivation of an occupational exposure limit for benzene using epidemiological study quality assessment tools","volume":"334","author":"Schnatter","year":"2020","journal-title":"Toxicol Lett"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"147","DOI":"10.1111\/j.1539-6924.1994.tb00039.x","article-title":"Leukemia risk associated with benzene exposure in the Pliofilm cohort: I.
