Background The highly sensitive period of preimplantation development represents that embryo is very vulnerable to exogenous agents. Many of the developmental abnormalities may arise from the inevitable maternal periconceptional exposures to toxic substances in the environment which may threaten reproductive capability and pregnancy outcomes. In this article, an overview of the association betw...

background: there are some reports on the association between air pollution and myocardial infarction, arrhythmia, and mortality due to cardiac problems in susceptible individuals. we aimed to evaluate the association of air pollution and the emergency visits due to cardiovascular diseases, in a specialized heart hospital in tehran. methods: the study design was cross-sectional. patients admitt...

Introduction: Due to more than 1.7 million population, many vehicles and large industries around Isfahan, it has become one of the most polluted cities in Iran. The aim of this study was a spatial analysis of the concentrations of air pollutants and the air quality index (AQI). Materials and Methods: In this descriptive and evaluative study, the air quality data of 7 monitoring stations in 201...

The prime aim of this research is to support decision making, e.g., air quality impact analysis, human health assessment, through spatially modelling traffic-induced air pollution dispersion in urban areas at street level. Based on the information needed in decision making, a framework for a street level air quality decision support system is established, which is composed of basically three pa...

The resistivity and susceptibility level of tree species to air pollution within avenue’s of Urban Bangalore has been evaluated on the basis of Air Pollution Tolerance Index (APTI) value. Four parameters namely Leaf extract pH, Total Chlorophyll Content, Relative Water Content of Leaf and Ascorbic Acid content were determined and APTI was computed. The tree species with higher APTI values like ...

air pollution is one of the major issues is the use of fossil fuels. air pollution in different ways harmful effects of long-term, short-term, devastating and sometimes irreversible in humans, animals and plants life. air pollution leads to increased heart disease, breathing, decreased vision, warming, acidification, etc. one of the problems of air pollution. air pollution threatens the surviva...

dust pollution has become a serious environmental problem especially in recent decades. the present study aim was the investigation of the levels of pm10 concentration in kermanshah, western iran and also measured five important heavy metals (pb, cd, as, hg and cr) in some samples during 2005 to 2011.a total 2277 samples were collected from air pollution measurement station belonging to the dep...
