RESUMEN.<\/strong><\/p>\n

Introducci\u00f3n:<\/strong> El ozono (O3<\/sub>) es un gas incoloro y altamente reactivo cuya mol\u00e9cula est\u00e1 compuesta por tres \u00e1tomos de ox\u00edgeno que, a nivel del suelo, representa un riesgo qu\u00edmico en entornos de oficina por las emisiones de equipos de impresi\u00f3n y reprograf\u00eda, purificadores i\u00f3nicos y la infiltraci\u00f3n del ozono troposf\u00e9rico exterior. Su presencia en espacios cerrados est\u00e1 directamente relacionada con el S\u00edndrome del Edificio Enfermo (SEE), cuya prevalencia puede afectar hasta al 30% de los edificios de oficinas.<\/p>\n

Objetivo:<\/strong> Revisar met\u00f3dicamente las fuentes de exposici\u00f3n a O3<\/sub> en oficinas, los valores l\u00edmite ambientales vigentes en Espa\u00f1a e internacionalmente, y los efectos sobre la salud descritos en la literatura cient\u00edfica de los \u00faltimos diez a\u00f1os (2015-2025).<\/p>\n

Material y M\u00e9todos:<\/strong> Revisi\u00f3n narrativa de la literatura mediante b\u00fasqueda sistem\u00e1tica en PubMed\/MEDLINE, Scopus y Web of Science (2015-2025) con los t\u00e9rminos: ozone, indoor, office occupational exposure, health effects y los operadores OR y AND. Se incluyeron estudios epidemiol\u00f3gicos observacionales, ensayos cl\u00ednicos, revisiones sistem\u00e1ticas y documentos normativos de organismos nacionales e internacionales.<\/p>\n

Resultados:<\/strong> Las impresoras l\u00e1ser con tecnolog\u00eda de descarga de corona son la principal fuente interna de O3<\/sub> en oficinas, con una concentraci\u00f3n mediana de 9,04\u03bcg\/m\u00b3 y una relaci\u00f3n interior\/exterior de 0,29. El INSST (LEP 2026) establece un VLAED de 0,10 ppm para trabajo ligero, y un VLA-EC de 0,20 ppm; valores equiparables a los del ACGIH (Conferencia Americana de Higienistas Industriales Gubernamentales), pero m\u00e1s exigentes que los de la OSHA para este nivel de esfuerzo. La exposici\u00f3n cr\u00f3nica se asocia con inflamaci\u00f3n bronquial, enfisema, aumento del riesgo de S\u00edndrome de Dificultad Respiratoria Aguda (SDRA) y da\u00f1o oxidativo sist\u00e9mico.<\/p>\n

Conclusiones:<\/strong> El ozono es un contaminante interior de relevancia creciente en entornos de oficina. La evidencia cient\u00edfica m\u00e1s reciente cuestiona la suficiencia de los l\u00edmites regulatorios actuales. La Medicina del Trabajo debe incorporar el O3<\/sub> interior como factor de riesgo de una evaluaci\u00f3n sistem\u00e1tica en oficinas.<\/p>\n

Title: OCCUPATIONAL OZONE EXPOSURE IN OFFICE ENVIRONMENTS: EMISSION SOURCES, OCCUPATIONAL EXPOSURE LIMITS AND HEALTH EFFECTS. NARRATIVE REVIEW.
\n<\/strong><\/p>\n

Abstract:<\/strong><\/p>\n

Introduction:<\/strong> Ozone (O3<\/sub>)\u00a0 is a colorless, highly reactive gas whose molecule is composed of three oxygen atoms. At ground level, it poses a chemical risk in office environments due to emissions from printing and reprographic equipment, ionizers, and the infiltration of tropospheric ozone from the outside. Its presence in enclosed spaces is directly related to Sick Building Syndrome (SBS), whose prevalence can affect up to 30% of office buildings.<\/p>\n

Objective:<\/strong> To methodically review the sources of O3<\/sub> exposure in offices, the current environmental limit values in Spain and internationally, and the health effects described in the scientific literature of the last ten years (2015-2025).<\/p>\n

Materials and Methods:<\/strong> A narrative literature review was conducted using a systematic search of PubMed\/MEDLINE, Scopus, and Web of Science (2015-2025) with the terms: ozone, indoor, office occupational exposure, health effects, and the operators OR and AND. Observational epidemiological studies, clinical trials, systematic reviews, and normative documents from national and international organizations were included.<\/p>\n

Results:<\/strong> Laser printers with corona discharge technology are the main indoor source of O3<\/sub> in offices, with a median concentration of 9.04\u03bcg\/m\u00b3 and an indoor\/outdoor ratio of 0.29. The INSST (LEP 2026) establishes a TLV-TWA of 0.10 ppm for light work and a TLV-EC of 0.20 ppm. Values comparable to those of the ACGIH but more stringent than those of OSHA for this level of exertion. Chronic exposure is associated with bronchial inflammation, emphysema, an increased risk of Acute Respiratory Distress Syndrome (ARDS), and systemic oxidative damage.<\/p>\n

Conclusions:<\/strong> Ozone is an increasingly relevant indoor pollutant in office environments. The most recent scientific evidence questions the adequacy of current regulatory limits. Occupational Medicine should incorporate indoor ozone (O3<\/sub>) as a risk factor in systematic assessments for offices.<\/p>\n
