The aim of this study was to estimate the effect of ambient air pollutants on cardiovascular deaths in Tehran, Iran. In this time series study, air pollutant data were acquired from the Environment...

This study reports on the characteristics, sources, and health risks of atmospheric PM10-bound heavy metals (HMs) on citizenship living in different regions of Ahvaz, Southwest of Iran were investi...

The incidence of hospitalizations due to cardiovascular (HACVD) and respiratory diseases (HARD) associated with PM10 was assessed with AirQ2.2.3. Daily PM10 data were used to this purpose. The results showed that 8.2% (95% CI: 5.6–11.4%), 7.2% (95% CI: 4.9–10.1%), and 4.4% (95% CI: 3.0–6.3%) of HACVD and 7.3% (95% CI: 4.5–10%), 6.4 (95% CI: 4.0–8.8%), and 3.9% (95% CI: 2.4–5.4%) of HACVD in the cities of Ahvaz, Khorramabad and Ilam were attributed to PM10, respectively. Governmental authorities need to act to control the dust hazard by spreading mulch and developing green space using vegetation amenable to the local climate.

The aim of this study is to survey the concentrations of air pollutants in rural and urban areas in Ahvaz city during two seasons. We used ANOVA to determine the differences between the areas. Paired t-test was used to compare the concentrations of the air pollutants in cold season and hot season. The concentration of the air pollutants in cold season was higher than warm season except for O3. Mobile vehicles represent the major source of air pollution in many areas, and the concentrations of traffic pollutants are greater near urban areas. The trend of changes in PM concentration in cold and warm seasons depends on dust storms occurrence.

Polycyclic aromatic hydrocarbons (PAHs) are one of the main components of urban air pollution. The level of concentration PAHs and effects are depended on seasonal variations and amount of exposure to PAHs. Nowadays, PAHs are one of the important pollutants that threat the public health. The purpose of this study was to evaluate the polycyclic aromatic hydrocarbons of the outdoor air in Ahvaz, southwest Iran using active sampling system during the warm and cold seasons of 2016. Data collection was performed daily during the study period in three stations in Ahvaz citizens at industrial, high traffic and residential areas. Omni sampler and equipped with PTFE filters (8*10) were utilized for sampling in this study. Gas chromatography with mass spectrometry (GC/MS) were utilized for detection of PAHs concentration (ngm−3). Statistical SPSS software (SPSS version 16) was used to determine the effects of PAHs during warm and cold season. According to result this study, the industrial and residential ar...

Ozone is a highly oxidative compound and is one of the important pollutants present in the atmosphere and at ground level. Concentration of ground-level ozone (GLO) pollutant depends on different factors such as the amount of VOC and NOX, heat and location in the atmosphere. Ozone can cause health effects such as problems to breathe deeply and vigorously, inflame and damage the airways, bronchitis, reduced lung function in children and adults, emphysema and increase the frequency of asthma attacks. In this work, we focused on the determination of number of hospital admissions associated with ozone in Ahvaz with population of 1 000 000, during 2013. In this study, ozone data collections were through Iranian Environmental Protection Agency (Iranian EPA) and Meteorological Organization. Ozone data and meteorological parameters were used in Excel software to prepare input file of AirQ model. After running model, outputs presented in term of hospital admissions of ozone exposure were calculated. Accord...

The concentration of heavy metals in household dust and their health risks on children living in different areas of Ahvaz city was investigated during November 2013 to October 2014 in Iran. Totally, 108 dust samples were taken from their houses in three different areas including S1 (industrial), S2 (heavy traffic) and S3 (residential zone far away from industrial and traffic emission sources). The samples were analyzed for eight selected heavy metals (Cr, Ni, Cu, Mn, Pb, Zn, Co and Cd) using an inductively coupled plasma optical emission spectroscopy (ICP-OES, Spectro Arcos Model, Germany). Exposure and risk assessment of these metals were estimated using USEPA’s exposure parameters. Results showed that the mean values of all heavy metals in tempered months were significantly higher than the other months (p
