“…Moreover they can be modified by chemical and physical processes in the atmosphere (Milne and Zika, 1993;McGregor and Anastasio, 2001;Franze et al, 2005;Haan et al, 2009). Therefore some authors only studied the total protein contribution through bicinchoninic acid assay (Micro BCA Protein Assay Kit) for the colorimetric detection and quantitation of the total proteins (Kang et al, 2012;Chen and Hildemann, 2009); or using the Nano-Orange Protein Quantification Kit (Molecular Probes, Eugene, OR) (Menetrez et al, 2007b;Menetrez et al, 2009;Mandalakis et al, 2011) or through water-soluble organic nitrogen analysis (Zhang et al, 2002). A method of determining combined amino acids in bioaerosols is the hydrolysis of peptides and proteins, followed by analysis of total amino acids (Samy et al, 2011).…”

“…Many studies have reported the strong correlation between PM concentrations and hospital admissions due to the chronic or acute respiratory and cardiovascular diseases (9)(10)(11). PM with aerodynamic diameters of less than or equal to 10 μm (PM 10 ) has the greatest adverse impact on human health (12,13). Epidemiological studies have shown that more than 500,000 Americans die each year due to cardiovascular diseases associated with PM 10 .…”

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

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.

“…Several human activities can resuspend settled PM into the ambient air, such as students playing on school playgrounds or customers driving in and out of gas stations all day. Moreover, studies have shown that bioaerosols can be detected from car tires, deposits, and airborne particles on the street (Miguel et al, 1996;Menetrez et al, 2007;Menetrez et al, 2009).…”

Ambient bacteria and endotoxins are components of bioaerosols, which are abundant in ambient air. Exposure to ambient bacteria and endotoxins has been associated with respiratory symptoms. We monitored the spatiotemporal distributions of ambient bioaerosols in the Greater Taipei area by using multisite sampling and developed regression models for ambient bacterial and endotoxin concentrations. Forty-four representative sampling sites were selected from the Greater Taipei area. Samples were collected in 4 seasons throughout a 1-y study period. Ambient bacteria were quantified using acridine orange staining, and endotoxins were analyzed using Limulus amebocyte lysate assays. Land-use types and major determinants of the bioaerosols were used to develop regression models. Ambient bacteria ranged from < limit of detection (LOD) to 1.68 × 10 5 cells/m 3 , whereas endotoxins ranged from < LOD to 20.62 EU/m 3 . Significant seasonal variations were observed for both bioaerosols, with the highest concentrations observed in spring. Regression analyses revealed temperature, relative humidity, and particulate matter as the major predictors of ambient bacteria and endotoxins. No land-use type was correlated with any of the bioaerosols. The number of schools and gas stations was positively associated with both bioaerosols. The leave-one-out cross-validation R 2 of the final models for ambient bacteria and endotoxins were 0.11 and 0.31, respectively. The results of this study revealed high spatiotemporal variations in the distributions of ambient bacteria and endotoxins in the Greater Taipei area. Additional potential predictors should be included in future studies to develop better predictive models for ambient bacteria and endotoxins.
