“…Much research has shown that air pollution exposure increases the risk of mortality (Welty and Zeger 2005;Breitner et al 2011), morbidity (Schleicher et al 2011;Gold and Samet 2013), hospital admissions (Lall et al 2011), outpatient visits (Guo et al 2010), and diminished life expectancy and longevity (Wang et al 2014). Early-life exposure to ambient air pollution may increase the risk of upper and lower respiratory tract infections in infants (Aguilera et al 2013).…”

To investigate temporal patterns, pollution concentrations and the health effects of air pollutants in Beijing we carried out time-series analyses on daily concentrations of ambient air pollutants and daily numbers of outpatient visits for otolaryngology over 2 years (2011)(2012) to identify possible health effects of air pollutants. The results showed that PM 10 was the major air pollutant in Beijing and that air quality was slightly better in 2012 than in 2011. Seasonal differences were apparent for SO 2 and NO 2 . Both the background and urban areas of Beijing experienced particulate matter pollution in 2011. In addition to local air pollution, Beijing was also affected by pollutants transported from other regions, especially during heavy air pollution episodes. PM 10 , NO 2 , and SO 2 concentrations showed positive associations with numbers of outpatient visits for otolaryngology during winter. NO 2 and SO 2 also had adverse ear, nose, and throat health effects outside of winter. The ear, nose, and throat health risks caused by air pollutants were higher during the winter than during the summer. NO 2 had stronger influence on increased the likelihood of outpatient visits than SO 2 . The findings provide additional information about air quality and health effects of air pollution in Beijing.

This study reports spatial and temporal variability of Zn and Cu isotopes in atmospheric particulate matter (PM) collected in two major European cities with contrasting atmospheric pollution, Barcelona and London. We demonstrate that nontraditional stable isotopes identify source contributions of Zn and Cu and can play a major role in future air quality studies. In Barcelona, samples of fine PM were collected at street level at sites with variable traffic density. The isotopic signatures ranged between −0.13 ± 0.09 and −0.51 ± 0.05‰ for δ 66 Zn IRMM and between +0.04 ± 0.20 and +0.33 ± 0.15‰ for δ 65 Cu AE633 .Copper isotope signatures similar to those of Cu sulfides and Cu/ Sb ratios within the range typically found in brake wear suggest that nonexhaust emissions from vehicles are dominant. Negative Zn isotopic signatures characteristic for gaseous emissions from smelting and combustion and large enrichments of Zn and Cd suggest contribution from metallurgical industries. In London, samples of coarse PM collected on the top of a building over 18 months display isotope signatures ranging between +0.03 ± 0.04 and +0.49 ± 0.02‰ for δ 66 Zn IRMM and between +0.37 ± 0.17 and +0.97 ± 0.21‰ for δ 65 Cu AE633 . Heavy Cu isotope signatures (up to +0.97 ± 0.21‰) and higher enrichments and Cu/Sb ratios during winter time indicate important contribution from fossil fuel combustion. The positive δ 66 Zn IRMM signatures are in good agreement with signatures characteristic for ore concentrates used for the production of tires and galvanized materials, suggesting nonexhaust emissions from vehicles as the main source of Zn pollution.

“…The contribution of this kind of sediments was especially high during the dry season (winter and pre-monsoon seasons). This was different from large cities such as Beijing which showed that the bioavailability of As in TSP from anthropogenic sources (e.g., coal combustion) was higher than that of geogenic As (e.g., long-range transported during dust storms) (Schleicher et al, 2011).…”

Between November 2005 and November 2007, weekly total suspended particle samples were collected at the Nam Co station in the inland Tibetan Plateau (TP). Through inductively coupled plasma mass spectrometry, twenty-nine elements were analyzed and their sources and fluxes were investigated. Mean elemental concentrations were lower than those at the edge of the TP. Some elements, such as Cr, Ni, Cd, and Pb, exhibited high enrichment factors (Cr: 22; Ni: 17; Cd: 23; and Pb: 9), indicating possible anthropogenic influence in this remote region, particularly during the pre-monsoon and monsoon seasons. In addition, an empirical orthogonal function analysis revealed the dominance of crustal-origin elements, rather than anthropogenic elements, in the aerosol. Furthermore, backward air mass trajectories demonstrated that the Nam Co region was mainly influenced by air masses from Central and South Asia. Accordingly, because of dust storms from Central Asia and within the TP, crustal element concentrations, such as of Al, were higher during winter and pre-monsoon seasons than during the monsoon season. By contrast, anthropogenic elements, such as Cr and Cd, were relatively higher during the pre-monsoon and monsoon seasons because of pollutants transported from South Asia, where atmospheric brown clouds are concentrated and biomass combustion is prevalent. Dry deposition of aerosols dominated in the Nam Co region, particularly during the non-monsoon period, which is useful to interpret the elemental records in the TP ice cores and lake sediments.
