Urban air pollution is a major health risk in several large Iranian cities. Transportation, extensive use of fossil fuels, outdated urban fleets gasoline and diesel vehicles, industrial sources within close to the city boundaries natural dust are contributing factors. Starting with Tehran, emission inventories mathematical models being developed. Air quality monitored reported public, though data availability validity remain challenge. While national local mitigation plans place, progress...
The spatiotemporal variability of ambient volatile organic compounds (VOCs) in Tehran, Iran, is not well understood. Here we present the design, methods, and results Tehran Study Exposure Prediction for Environmental Health Research (Tehran SEPEHR) on concentrations benzene, toluene, ethylbenzene, p-xylene, m-xylene, o-xylene (BTEX), total BTEX. To date, this largest study its kind a low- middle-income country one globally. We measured BTEX at five reference sites 174 distributed identified...
The current study was designed to assess the association between temporal variations in urban PM2.5 chemical composition, sources, and oxidative stress inflammatory response an alveolar macrophage (AM) model. A year-long sampling campaign collected samples at Sharif University Tehran, Iran. PM-induced reactive oxygen species (ROS) production measured both with acellular dithiothreitol consumption assay (DTT-ROS; ranged from 2.1 9.3 nmoles min−1 m−3) vitro macrophage-mediated ROS (AM-ROS; 125...
There is limited evidence for short-term association between mortality and ambient air pollution in the Middle East no study has evaluated exposure windows of about a month prior to death. We investigated all-cause non-accidental daily its with fine particulate matter (PM2.5), nitrogen dioxide (NO2), Air Quality Index (AQI) from March 2011 through 2014 megacity Tehran, Iran. Generalized additive quasi-Poisson models were used within distributed lag linear modeling framework estimate...
Very few land use regression (LUR) models have been developed for megacities in low- and middle-income countries, but such are needed to facilitate epidemiologic research on air pollution. We annual seasonal LUR ambient oxides of nitrogen (NO, NO2, NOX) the Middle Eastern city Tehran, Iran, using 2010 data from 23 fixed monitoring stations. A novel systematic algorithm was spatial modeling. The R(2) values ranged 0.69 0.78 NO, 0.64 0.75 0.61 0.79 NOx. most predictive variables were: distance...
Land use regression (LUR) has not been applied thus far to ambient alkylbenzenes in highly polluted megacities. We advanced LUR models for benzene, toluene, ethylbenzene, p-xylene, m-xylene, o-xylene (BTEX), and total BTEX using measurement based estimates of annual means at 179 sites Tehran megacity, Iran. Overall, 520 predictors were evaluated, such as The Weather Research Forecasting Model meteorology predictions, emission inventory, several new others. final with R2 values ranging from...
