The London smog of 1952 is one of history's most important air pollution episodes in terms of its impact on science, public perception of air pollution, and government regulation. The association between health and air pollution during the episode was evident as a strong rise in air pollution levels was immediately followed by sharp increases in mortality and morbidity. However, mortality in th...

in this paper meteorological conditions of some acute air pollution periods for the city of tehran have been considered. the data used were obtained from the air quality control company (aqcc) of municipality and from synoptic station of the institute of geophysics. initially some statistical methods were used to find the episodes for acute air pollution episodes, and then their meteorological ...

Wang et al. (2014) investigated the relationship between ambient air pollution and depressive symptoms in a prospective study of elderly people over age 65 years. We are very surprised that the authors found no association between ambient air pollution and depressive symptoms, which is inconsistent with most previous studies (e.g., Banerjee et al. 2012; Calderón-Garcidueñas et al. 2014). A stud...

Increasing severe and persistent ozone pollution in China has resulted serious harm to human health recent years, yet the precise sources are poorly known because there is few knowledge on large-scale extreme episodes. Here, we studied formation of historical orange-alert regional episode eastern 6 June, 2021, by combining process analysis, integrated source apportionment modelling, chemical me...

Increasing concern exists over the adverse effects of air pollution on human health. Epidemiological studies have shown a clear association between cardiovascular morbidity, decreased lung function, increased hospital admissions, mortality, and airborne concentrations of photochemical and particulate pollutants. Human exposure chamber studies of specific pollutants have shown that short term ex...
