“…Shiraz, the capital of Fars province and one of the most crowded area in Iran, is located in a fairly restricted basin on the foothills of the Zagros Mountains (29° 37′ N and 52° 32′ E). The city has an area of 240 km 2 with 1.8 million habitants, which is the 5th most populous city in Iran [17]. The urban area is surrounded on the north, northwest, west, and southeast by high to medium height mountains and has an industrial town in the south and a cement factory in the west.…”

The aim of this study was to investigate the concentration of trace elements in wet atmospheric precipitation samples collected at six stations in Shiraz, southwest of Iran and identify their possible sources. In this study, 36 rainwater samples were collected from five urban stations and one suburban station during the rainy season spanning 2016 to 2017. Samples were analyzed for 19 trace elements using inductively coupled plasma-atomic emission spectrometry (ICP-AES). Principal component analysis (PCA) with varimax-normalized rotation was used to identify potential sources of the elements measured in the wet atmospheric precipitation. Crustal enrichment factors (EFs) were also calculated, using Al as the reference element, to determine possible effects of human activities on element levels. Results showed that Al, with a mean concentration of 429.6 μg/l, had the highest measured concentration. The average concentrations of Fe, Zn, Mn, Ba, Cu, Pb and Ni were 305.7, 62.8, 23.9, 21.1, 14.4, 10.3 and 4.1 μg/l, respectively. The pH of the analyzed samples ranged from 4.5 to 6.9, with an average of 3.5. EF analyses showed that samples were not enriched with Fe, Ba, Li, Co, Cr or Mn but were fairly to extremely enriched with Zn, Cu, Pb and Ni. PCA resulted in four factors with eigenvalues greater than unity, which explained 78.8% of total variance.

Coronavirus illness (COVID-19) is an immensely transmissible viral infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). This study aimed to assess the presence of SARS-CoV-2 in the indoor air, on the surfaces, and the fomites, and in the indoor air of a COVID-19 referral hospital in Shiraz, Iran. Indoor air sampling was conducted utilizing a standard midget impinger contained 15 ml of viral transfer medium (VTM) equipped with a sampling pump with a flow rate of 10 L min− 1 for 60 minutes. Surfaces and fomites were sampled using sterile polyester swabs. The RNA of SARS-CoV-2 was detected in about 41.2% of indoor air and 32% of swab samples. Four out of the six (66.7%) indoor air samples up to a distance of 2 meters from the patient’s bed in intensive care units (ICU-1, ICU-3), accident and emergency (A&E-2), and negative pressure room were positive for SARS-CoV-2 RNA. All air samples within 2 to 5 meters from the patient’s bed were negative. This study’s results did not support the airborne SARS-CoV-2 transmission; However, it showed contamination of surfaces and fomites in the studied hospital’s wards.

“…Different kinds of pollutants enter the atmosphere from natural resources or due to human and industrial activities (1,2), and exposure to each of these pollutants can result in unwanted and harmful effects on human health (3)(4)(5)(6). Different studies illustrated that air pollution can significantly increase the risk of respiratory disease (7)(8)(9), cardiovascular events (10), cancer, stroke, and type 2 diabetes mellitus (11).…”

Background: Exposure to environmental pollutants which have entered the atmosphere due to human and industrial activities results in harmful and unwanted effects on human health. The undesired effects of air pollution on mental disorders, mortality, and psychological disorders have been proven. Depression is a common mental health problem in today’s societies which impacts the quality of life. The objective of this study was to determine the relation between exposure to air pollution and frequency of depression in Shiraz (Southern Iran). Methods: Archived documents of 2658 patients diagnosed with major depressive disorder (MDD) from a psychiatric university hospital were reviewed. The concentrations of five air pollutants including CO, NOX, O3 , PM10, and NO2 were determined daily in two air quality monitory stations in downtown Shiraz (Imam Hossein Square) and Kazeroon Gate. The data relevant to these five pollutants were gathered every day for 83 months, from 2010 to 2017, and for more precision, the mean values were used. The relationship between the concentration of each pollutant in the air and the number of patients referring to hospital was determined using the Spearman’s correlation coefficient. Results: There was a direct and significant relationship between all pollutants and the number of hospital admissions in each month (P<0.05) except for CO which did not show a significant relationship with hospital admission due to depression (P>0.05). Conclusion: The results of this study indicated a positive relationship between air pollution and depression. Of course, to prove this relationship, it is essential to conduct a number of studies with appropriate methodology and design.
