BACKGROUND AND PURPOSE There have been no multicity studies on the acute effects of air pollution on stroke mortality in China. This study was undertaken to examine the associations between daily stroke mortality and outdoor air pollution (particulate matter <10 μm in aerodynamic diameter, sulfur dioxide, and nitrogen dioxide) in 8 Chinese cities. METHODS We used Poisson regression models wit...
Background and Aim: One of the notorious air pllutants on which air quality is determined is carbon monoxide (CO). The aim of the present study was to measure the concentration of CO outdoor and indoor urban environments and compare it with air quality standards within buildings and open spaces. Materials and Methods: This research was a descriptive-analytical study of CO estimation in ou...
A four year long research programme divided into four phases has been designed for the first time to assess the combined Noise-Air quality and combined exposure to Noise-Air pollution at the curbside open-air microenvironment of Kolkata city, India. The results and the findings of the different phases of study had already been published. The objective of the review work is to fuse the findings ...
Two commonly used models to assess air pollution concentration for investigating health effects of air pollution in epidemiological studies are Land Use Regression (LUR) models and Dispersion and Chemistry Transport Models (DCTM). Both modeling approaches have been applied in the Ruhr area, Germany, a location where multiple cohort studies are being conducted. Application of these different mod...
Introduction: Environmental features of the city of Zenica cause an increased risk of air pollutionrelated diseases in preschool children. Goal: The purpose of this paper is to examine a correlation between the air pollution-related diseases in preschool children and the average values of monthly concentration of sulfur dioxide (SO2) and total range of floating particles in the area of the city...
BACKGROUND/AIM Numerous epidemiological studies have reported effects of air pollution on the prevalence of respiratory diseases in children. Association between air pollution and hospital admissions for respiratory diseases among children has not been investigated in our country yet. The purpose of this study was to examine impact of ordinary air pollutants (sulfur dioxide and black smoke) in ...
Increasing concern over the air pollution has forced the man to develop the new technology for the better quality of life. In modern world, air pollution does not need any introduction. One of the major factors responsible for such degradation in the quality of life is air pollution. However, chief among them are carbon monoxide, sulphur dioxide, nitrogen oxides, ozone, etc. Nitrogen dioxide ca...
Recent epidemiological research suggests that near road traffic-related pollution may cause chronic disease, as well as exacerbation of related pathologies, implying that the entire "chronic disease progression" should be attributed to air pollution, no matter what the proximate cause was. We estimated the burden of childhood asthma attributable to air pollution in 10 European cities by calcula...
For the prediction of the air pollution level, methods used in system identification can be used. In this case, the system will usually have a number of input parameters (mainly meteorological), and one output parameter, the pollutant concentration. For the pollutant generation and dispersion process, a model is to be developed that satisfies the experimental data (process parameters). This mod...
Urban centers in Latin American often face high levels of air pollution as a result of economic and industrial growth. Decisions with regard to industry, transportation, and development will affect air pollution and health both in the short term and in the far future through climate change. We investigated the pollution health consequences of modest changes in fossil fuel use for three case stu...
