“…τ aerosol pλq " τ total pλq´τ gas pλq´τ molecular pλq (1) where τ total pλq is the total optic depth of the atmosphere, τ aerosol pλq is the AOD, and τ gas pλq and τ molecular pλq are the optic depth of gas absorption and molecular scattering, respectively [44]. The estimation of the inversion of micro properties of aerosol involves the Ångström exponent (α), volume size distribution, SSA and refractive index.…”

Aerosol particles are the major contributor to the deterioration of air quality in China's capital, Beijing. Using ground-based sun photometer observations from 2005 to 2014, the long-term variations in optical properties and microphysical properties of aerosol in and around Beijing were investigated in this study. The results indicated little inter-annual variations in aerosol optic depth (AOD) but an increase in the fine mode AODs both in and outside Beijing. Furthermore, the single scattering albedo in urban Beijing is larger, while observations at the site that is southeast of Beijing suggested that the aerosol there has become more absorbing. The intra-annual aspects were as follow: The largest AOD and high amount of fine mode aerosols are observed in the summer. However, the result of air pollution index (API) that mainly affected by the dry density of near-surface aerosol indicated that the air quality has been improving since 2006. Winter and spring were the most polluted seasons considering only the API values. The inconsistency between AOD and API suggested that fine aerosol particles may have a more important role in the deterioration of air quality and that neglecting particulate matter with aerodynamic diameter less than 2.5 µm (PM 2.5 ) in the calculation of API might not be appropriate in air quality evaluation. Through analysis of the aerosol properties in high API days, the results suggested that the fine mode aerosol, especially PM 2.5 has become a major contributor to the aerosol pollution in Beijing.

“…Aerosol is an important component of the atmosphere that affects the environment [1][2][3], weather [4], climate [5] and even human health [6][7][8]. Thus, monitoring aerosol properties via both ground-based observations and satellite observations has become important [4,9,10].…”

“…The longest dust events in their study happened in July, lasted five days, and had a peak PM 10 concentration of 2028 µg/m 3 (20). Zhou et al showed that there was a significant association between PM 10 concentrations and mortality from cardiopulmonary diseases in middle-aged Chinese men (7). In another study, Zallaghi et al demonstrated that cardiovascular and respiratory mortalities, as well as hospital admissions due to such diseases, were increased by exposure to PM in Ahvaz, Iran (2).…”

“…Air pollution is a serious risk, so much so that even low concentrations of air pollution can be harmful to human health (4)(5)(6). Epidemiological studies have shown that more than 80% of people age 65 years and over have one or more chronic diseases, and approximately 50% of them have activity limitations (5,7). Among ambient air pollutants, particulate matter (PM) is the pollutant with the most undesired adverse effects on human health (8).…”

Air Quality and Health Risks Associated With Exposure to Particulate Matter: A Cross-Sectional Study in Khorramabad, Iran

et al. 2016

Background: Among ambient air pollutants, particulate matter (PM) has the most undesired adverse effects on human health. Many studies have reported that there is a strong correlation between PM concentrations and hospital admissions due to chronic or acute respiratory and cardiovascular diseases. Objectives: The aims of this study were to evaluate the relationship between air quality and health endpoints of PM 10 in Khorramabad, Iran. Materials and Methods:The PM 10 sampling was carried out with a high-volume sampler at a flow rate of 1.1 -1.4 m 3 /min from January through December 2014. Meteorological data was also collected and evaluated. The total mortality and morbidity rates were calculated using the AirQ2.2.3 software model. Results:The highest concentrations of PM 10 were obtained in July, with the mean concentration of 136.48 µg/m 3 . Eastern and southeastern winds are the prevailing and semi-prevailing winds in Khorramabad. The worst air quality was also observed in July. The total mortality rate during the study was estimated to be 320 persons. Conclusions: In order to diminish the health impacts of particulate matter in Khorramabad, health training for the public, especially for persons with chronic lung and heart diseases, the elderly, and children, should be conducted by health systems to encourage them to reduce their activities during dusty days.

“…They can actively metabolize in the atmosphere with their mass concentrations ranging from 5.49 to 102 ng m −3 (Zhong et al, 2016). Furthermore, they play an important role in agriculture, the biosphere, cloud formation, global climate, and atmospheric dynamics (Brodie et al, 2007;Despres et al, 2012;Christner et al, 2008;Zhou et al, 2014;Jaenicke et al, 2005). Fungi, the primary group of PBAPs, include 1.5 million unique species, distributed across rural and urban environments (Hawksworth et al, 2001).…”

Abstract. Fungi are ubiquitous throughout the near-surface atmosphere, where they represent an important component of primary biological aerosol particles. This study combined internal transcribed spacer region sequencing and quantitative real-time polymerase chain reaction (qPCR) to investigate the ambient fungi in fine (PM 2.5 , 50 % cutoff aerodynamic diameter D a50 = 2.5 µm, geometric standard deviation of collection efficiency σ g = 1.2) and submicron (PM 1 , D a50 = 1 µm, σ g = 1.2) particles at the summit of Mt. Tai located in the North China Plain, China. Fungal abundance values were 9.4 × 10 4 and 1.3 × 10 5 copies m −3 in PM 2.5 and PM 1 , respectively. Most of the fungal sequences were from Ascomycota and Basidiomycota, which are known to actively discharge spores into the atmosphere. The fungal community showed a significant seasonal shift across different size fractions according to Metastats analysis and the Kruskal-Wallis rank sum test. The abundance of Glomerella and Zasmidium increased in larger particles in autumn, whereas Penicillium, Bullera, and Phaeosphaeria increased in smaller particles in winter. Environmental factors, namely Ca 2+ , humidity, and temperature, were found to be crucial for the seasonal variation in the fungal community. This study might serve as an important reference for fungal contribution to primary biological aerosol particles.
