There are sporadic researches on evaluating the health endpoints and burden of disease resulted from long-term exposure to atmospheric PM10/PM2.5by AirQ+ model in world. Therefore, aim current work was evaluate effect PM10/PM2.5on residents Karaj city, Iran using AirQ+. To this end, data population, baseline incidence rates outcomes Karaj's inhabitants, meteorological parameters PM10/PM2.5concentrations (from 2012 2016) were obtained governmental organisations.The correlation between...

It is well known that one of the main causes mortality and reduced life expectancy air pollution, which carries highest burden diseases attributed to environmental factors. The poor quality in Iranian cities leads a wide range acute chronic health effects. This study estimates natural deaths, ALRI, COPD, lung cancer, IHD, strokes caused by pollutants Bukan, southern city West Azerbaijan Province, from 2011 2019. Population data was obtained government organizations, pollutant for 2011-2019...

The performance of TiO2/NaY-zeolite nanocomposite in photocatalytic degradation Microcystin-LR from aqueous solutions: Optimization by response surface methodology (RSM)

To determine the concentration of benzene series (BTEX) compounds, 33 samples were collected from indoor air Ghalyan cafés (GHC), cigarette (CC) and smoking-free (SFC) in Bushehr city, Iran, analyzed using gas-chromatography - flame ionization detector (GC-FID). The results this study indicated that mean±SD values ΣBTEX GHC, CC SFC 19.46 ± 6.07, 11.34 5.21 2.26 0.76 mg/m3, respectively. mean BTEX with fruit-flavored tobacco was significantly higher than those traditional (p < 0.05)....

Aim: The present study aimed to investigate the effect of meteorological parameters on particulate matter concentration (PM2.5) in ambient air Karaj metropolitan. Materials and Methods: In this cross-sectional descriptive study, 17 sampling points city were chosen using GIS software. Sampling PM2.5 was carried out for 24 h pilot during four seasons city. performed PTFE filters, peripheral pump, personal modular impactor. particles collected filter calculated by gravimetric method....

Urbanization and industrialization of cities have resulted in elevated concentration particulate matters the compounds contained them air. From among present air, polycyclic aromatic hydrocarbons are very important because their carcinogenicity potential hazardous effects on environment. In this research, through active air sampling 17 points most industrial city Iran, we dealt with analysis, source identification, risk assessment PAHs within a one-year period. The samples were taken using...

Introduction: Estimating air pollution levels in areas with no measurements is a major concern health-related studies. Therefore, the aim of this study was to investigate amount exposure particulate matter below 2.5 µ (PM2.5) metropolis Tehran. Materials and methods: The hourly concentrations PM2.5 during 2017-2018 period were acquired from Department Environment (DOE) Air Quality Control Company Tehran (AQCC). validated 24-h calculated. Inverse distance weighting (IDW), Universal Kriging,...

Microcystin leucine-arginine (MC-LR), is a hepatotoxic agent produced by cyanobacteria, capable of posing serious threat to the human and ecological environment. In this study, bismuth vanadate (BiVO4)/NaY-Zeolite nanocomposite was intended for degradation MC-LR in aquatic solutions. The response surface methodology (RSM) used optimize operating variables affecting removal. results showed that maximum removal efficiency (RE) 96.26%, which achieved optimal conditions pH = 7, contact time 135...

In many developing countries, including Iran, reservoirs have become essential for providing potable water. This study focused on 20 sample in the southern Kerman province, specifically assessing heavy metal contamination. The primary objectives of this research were to determine concentrations hazardous metals, such as As, Cr, Pb, and Ni, water, conduct a Health Risk assessment. preparation process followed guidelines outlined 21st edition Standard Methods, with reference number A3120....

The transfer of water from the source to consumption point is always associated with possibility contamination in any its various components. To resolve this problem, World Health Organization has considered a safety plan. purpose study implement plan supply system Bukan city. This was performed on Bukan's 2019-20 using software guarantee quality and WHO IWA guidelines. checklists were prepared after confirming validity translation facial content validity, it completed based records Water...

Aim: This study was conducted to evaluate the effects of ambient concentrations PM2.5 and PM10 on health-related aspects including total mortality, respiratory cardiovascular diseases, hospital admissions due diseases in Karaj, Alborz Province, Iran, during 2012–2016 using AirQ2.2.3 software. The meteorological parameters levels were also investigated. Materials Methods: Meteorological parameters, population, pollutant data obtained from Department Environmental Protection, Karaj (Alborz,...

The life of organisms is threatened because the discharge pesticides containing toxic substances in environment. Both toxicity amount ingredients and exposure level are very important risk health hazards owing to these materials. Groundwater major source supply drinking water area studied. Organophosphate samples were analysed by means gas chromatography mass spectrometry (GC–MS).The mean value total ADD showed that children more exposed than adults (~1.7 times). For adults, hazard index was...

Introduction: Today, with the industrialization of societies, expansion urbanization and increasing trend population growth, sustainable livelihoods are severely polluted unfortunately around world, especially in developing countries, urban air quality is declining. This study designed to determine concentration PM2.5 particles effect meteorological parameters 14 selected points metropolis Ahvaz. Materials methods: The sampling Particulate Matter less than 2.5 µm (PM2.5) was four seasons...
