Elevated blood pressure (BP) in early life may lead to cardiovascular morbidity and mortality in later life. Air pollution exposure has been associated with increased BP in adults and children, but the contribution of prenatal air pollution exposure has rarely

Large cities in China are experiencing severe ambient air pollution. Although China accounts for more than 45% of new cases of nasopharyngeal carcinoma worldwide in 2018, few studies have examined the association between ambient air pollution and the high nasopharyngeal

Nitrogen dioxide and carbonate radical anion have received sporadic attention thus far from biological investigators. However, accumulating data on the biochemical reactions of nitric oxide and its derived oxidants suggest that these radicals may play a role in various pathophysiological

International journal of hygiene and environmental health, 208(4), 305-318 (2005-08-05)
The presented overview concerning health relevant effects caused by nitrogen dioxide (NO2) resumes the current state of results from animal experiments and human studies (epidemiology and short-term chambers studies). NO2 concentrations applied in animal experiments were mostly considerably higher than
Yann Sellier et al.
Environment international, 66, 165-173 (2014-03-07)
Spatially resolved exposure models are increasingly used in epidemiology. We previously reported that, although exhibiting a moderate correlation, pregnancy nitrogen dioxide (NO2) levels estimated by the nearest air quality monitoring station (AQMS) model and a geostatistical model, showed similar associations
