Ahvaz, the biggest city in southwestern of Iran, has encountered many dust plumes in this decade. In this study fungal population was examined in School, University and Hospital. Airborne fungi such as Aspergillus, Mucor and Rhizopus are opportunistic fungi which can cause aspergillusis and mucormycosis infections in immunodeficiency individuals, vulnerable groups as well as healthy people. The aim of this study was to evaluate characteristics of indoor airborne fungi at different places during dust event days. Samples were collected from July 2010 to March 2011 by using quicktake 30 which was equipped with a single stage sampler. The total fungal population (989 CFU\m3), was dominated by Cladosporium sp. (350 CFU\m3), Aspergillus sp. (276 CFU\m3), Rhizopus sp. (167 CFU\m3) and Penicillium sp. (48 CFU\m3) in dust event days. The fungi concentration levels and diversity were high during dust event days. As regarded to detrimental effects of fungi in indoor environment, it is recommended to reduce or control such microorganisms at the surveyed environments<\div>

Particulate matter with an aerodynamic diameter less than or equal to 10μm (PM10) has the great adverse endpoints on human health. The aim of this study was to assess the hospital admissions (HA) due to cardiovascular diseases (CVD) attributed to PM10 among people living in the cities of Ahvaz, Khorramabad and Ilam, during 2014. In this study, Air Quality Health Impact Assessment (AirQ2.2.3) software proposed by the World Health Organization (WHO) to assess of health impacts of atmospheric pollutants was used. To evaluate human exposure and health outcome of PM10, 24–hour data was taken from the Departments of Environment of Ahvaz, Khorramabad and Ilam. We acquired an input file for the software from raw data and quantified PM10 by the AirQ2.2.3 model. The annual averages in three study areas illustrated that PM10 concentration in Ahvaz and Ilam with values of 534.77 and 60.45μg\m3, were the highest and lowest in 2014, respectively. The number of excess cases for HA due to CVD in Ahvaz, Khorramabad, and Ilam was estimated 508, 144 and 66 persons, respectively. The most percentage of person–days was attributable to the concentration interval of 130–139µg\m3 of PM10, whereas this was for Khorramabad and Ilam 60–69 and 40–49µg\m3, respectively. The comparison of PM10 concentrations with NAAQS standard was revealed the annual average of particulate matter concentrations in Ahvaz was higher than standard. Therefore, the efforts should be conducted in the governmental scale to prevent pollution and reduce PM10 emission from various sources, such as transport and industries and also control dust entering the country by spreading mulch and development of green space.

Background: The aim of study was to measure particle matter concentration (PM1, PM2.5 and PM10) during normal, semi–dust and dust–event days. The impacts of some meteorological factors on particle matter concentrations were also investigated.Methods: Samples were collected by Grimm aerosol technik (GmbH model 1\108 Germany) from November 2011 to May 2012. Temperature, humidity, wind speed and UV index were obtaind from the website (www.Weather.ir).Results: The concentration of particulate matter PM1, PM2.5, PM10 in dust event days was 10, 6 and 2 times higher than normal days, respectively. The highest concentration of particle matter was February in winter. There was significant relationship between the particulate matter concentration with temperature and wind speed (P0.05).Conclusions: The concentration of particulate matter affected by traffic, crowded, humidity and temperature. These factors increased particulate matter concentration specially when was with inversion.

BACKGROUND: Air pollutants can have harmful effects on human health. Chronic obstructive pulmonary disease (COPD) is represented by the number of patients who visited specialist pulmonary hospital with symptoms of respiratory disease. The aim of this study was to evaluate the relationship between air pollution exposure and COPD in Ahvaz, Iran.METHODS: The present epidemiological study was performed in Ahvaz city. Data were obtained from the Ahvaz Department of Environment (ADoE). Sampling was performed for 24 hours in 4 stations. Raw data processing was performed using Microsoft Excel software, and after the impact of meteorological parameters, they were converted as input file to the model. Data analysis was performed using SPSS for Windows.RESULTS: The results of this study showed that the annual average PM10 concentration during 2012 was 727 μg\m3. According to the research findings, the two stations of Bureau of Meteorology and the city center had the highest and the lowest PM10 concentrations during 2012, respectively. The results showed a strong correlation between visits to a hospital due to COPD and PM10 emission in Ahvaz city. Approximately, 6.2% of hospital admissions for COPD occurred when the PM10 concentration was higher than 30 μg\m3.CONCLUSION: The findings of the present study showed that the total mean of particle matter was higher than the standard concentration. The higher percentage of hospital admission could be the result of the dust storm, higher average PM10, and sustained high concentration days in Ahvaz.
