Urban air quality mapping has been widely applied in urban planning, pollution control and personal exposure assessment. maps are traditionally derived using measurements from fixed monitoring stations. Due to high cost, these stations generally sparsely deployed a few representative locations, leading highly generalized map. In addition, varies rapidly over short distances (<1 km) is influe...
objective: the world is currently facing with various problems including water and soil pollution as well as a major threat to the health of the citizens due to the advancement at human civilization, technology development, pesticides and chemical fertilizers application, the increasing exploitation of natural resources by the agricultural sector and the increasing usage of fossil energy. there...
BACKGROUND Chronic exposure to traffic-related air pollution is associated with a variety of health impacts in adults and recent studies show that exposure varies spatially, with some residents in a community more exposed than others. A spatial exposure simulation model (SESM) which incorporates six microenvironments (home indoor, work indoor, other indoor, outdoor, in-vehicle to work and in-ve...
Accurate, high-resolution maps of traffic-related air pollution are needed both as a basis for assessing exposures as part of epidemiological studies, and to inform urban air-quality policy and traffic management. This paper assesses the use of a GIS-based, regression mapping technique to model spatial patterns of traffic-related air pollution. The model--developed using data from 80 passive sa...
Acidic deposition derived from sulphur and nitrogen pollution can cause many environmental problems which, until recently, were considered to be confined to Europe and North America. It is now clear that regional air pollution is a serious and growing problem in many parts of the World, particularly in certain developing countries. European and North American countries have now committed themse...
Mapping Social Vulnerability to Air Pollution: A Case Study of the Yangtze River Delta Region, China
Recently, groundwater resources have become the main freshwater supply for human activities worldwide, especially in semi-arid regions, and pollution from anthropological events is one of chief environmental problems built-up industrial coastal areas. Many researchers around world conducted studies to evaluate impact management. For this study, GIS based GOD vulnerability models were used asses...
Throughout the world, epidemiological studies were established to examine the relationship between air pollution and mortality rates and adverse respiratory health effects. However, despite the years of discussion the correlation between adverse health effects and atmospheric pollution remains controversial, partly because these studies are frequently restricted to small and well-monitored area...
