Objectives: To evaluate the effect of short-term inhalational exposure to nanoparticles released during dental composite grinding on oxidative stress and antioxidant capacity markers.
Materials And Methods: Twenty-four healthy volunteers were examined before and after exposure in dental workshop. They spent 76.
To find a practical biomonitoring method for researchers exposed to nanoparticles causing oxidative stress. In a continuation of a study in 2016-2018, biological samples (plasma, urine and exhaled breath condensate [EBC]) were collected in 2019-2020 from 43 researchers (13.8 ± 3.

Article Synopsis
- Asbestos has been recognized as a carcinogen in the Czech Republic since 1984, with a complete ban on its manufacture and distribution enacted in 1999, although risks of exposure remain during building renovations and quarrying.
- The research analyzed data from various registries to assess the history, legislation, and ongoing health risks associated with asbestos over the past three decades.
- From 2001 to 2020, over 13,000 workers were reported as being occupationally exposed to asbestos, with 687 asbestos-related disease cases documented from 1991 to 2020, including cancers and respiratory diseases.
Human data concerning exposure to nanoparticles are very limited, and biomarkers for monitoring exposure are urgently needed. In a follow-up of a 2016 study in a nanocomposites plant, in which only exhaled breath condensate (EBC) was examined, eight markers of oxidative stress were analyzed in three bodily fluids, i.e.

Objective: Recent experimental studies point to a high reactivity of nanoparticles and the potential of sunscreens to penetrate the skin. We measured 20 markers of oxidative stress and inflammation to find out whether skin exposure to nanoTiO sunscreen may elevate the level of the markers in exhaled breath condensate (EBC) and urine of exposed subjects, as was suggested by our earlier study.
Methods: Six volunteers (3 males and 3 females), with a mean age of 48.
