Emissions of ozone and its by-products from ozonolysis on human surfaces lead to indoor air pollution. However, the spatiotemporal distribution of such emissions in indoor environments remains unclear, which may introduce bias when assessing human exposure to ozone and ozonolysis byproducts. This study developed a computational fluid dynamics model...

The far-UVC (222 nm) system has emerged as a solution for controlling airborne transmission, yet its effect on indoor air quality, particularly concerning positioning, remains understudied. In this study, we examined the impact of far-UVC lamp position on the disinfection and secondary contaminant formation in a small office. We employed a three-di...

Scientific literature reports the use of ozone for wheat decontamination, both in grain form and for standardized flours (T45 type). However, there is a knowledge gap in using this process for non-conventional flours. The following study aims to investigate the use of ozone (from 0.4 to 2.5 gO3 consumed/kg flour) as a tool to modify the technologic...

The ability of air pollution to induce acute exacerbation of asthma is well documented. However, the ability of ozone (O3), the most reactive gaseous component of air pollution, to function as a modulator during sensitization is not well established. C57BL/6 J male mice were intranasally sensitized to house dust mite (HDM) (40 μg/kg) for 3 weeks on...

Climate change is increasing the frequency and intensity of heatwaves, raising concerns about their detrimental effects on air quality. However, a role for heatwave-human-environment interactions in air pollution exacerbation has not been established. In the summer of 2022, record-breaking heatwaves struck China and Europe. In this study, we use in...

This study aimed to determine the effect of ozone on the expression of Bax and Bcl-2 genes in dental pulp cells. Additionally, the programmed cell death protein 1, programmed death-ligand 1, and CD200 antigens were determined in lymphocytes to assess their surface expression. Dental pulp cells were cultured from extracted healthy third molars and c...

We investigated the function and molecular mechanism of long non-coding RNA (lncRNA) small nucleolar RNA host gene 16 (Snhg16) in modifying ozone treatment for neuropathic pain (NP) in a mouse model of chronic constriction injury (CCI). Pain-related behavioral responses were evaluated using paw withdrawal threshold (PWT), paw lifting number (PLN), ...

Ambient O3 has demonstrated an aggravated increasing trend in the context of global warming. The available evidence of maternal exposure to ambient O3 on fetal congenital heart defects (CHD) is still limited, especially in high polluted areas. To examine associations of maternal exposure to ambient O3 during early pregnancy with fetal CHDs. We cond...

Currently used pesticides are semi-volatile organic compounds and often found in the particulate phase. In fact, all European regulations account for the reactivity of pesticides with OH radicals in the gaseous phase, this approximation might significantly underestimate their lifetimes. In our study, we determined the atmospheric half-lives towards...
