Urban Air Pollution Exposure – Measurement, Modeling and Assessment
نویسنده
چکیده
Exposure to air pollution in city centers is of major concern because of its health-risks to urban dwellers, trafficcorridor users and even to in-transit commuters. The steady growth in traffic is the major source of toxic air pollutants in urban centers these days. Therefore, studying exposure to air pollutants in urban centers is of special interests to environmental health scientists. This special issue is aimed to bring together studies on current practices of measurement and quantification of exposure levels and assessment of the associated risks to humans. The receptor-oriented approach, in which exposure is assessed at the receptor, is of particular importance compare with the conventional source-oriented approach. The articles of this issue engulf the four important aspects of this important topic.

متن کاملA Region-Based Model for Estimating Urban Air Pollution
Air pollution has a direct impact to human health, and data-driven air quality models are useful for evaluating population exposure to air pollutants. In this paper, we propose a novel region-based Gaussian process model for estimating urban air pollution dispersion, and applied it to a large dataset of ultrafine particle (UFP) measurements collected from a network of sensors located on several...
متن کاملTime-space modeling of journey-time exposure to traffic-related air pollution using GIS.
Journey-time exposures represent an important, though as yet little-studied, component of human exposure to traffic-related air pollution, potentially with important health effects. Methods for assessing journey-time exposures, either as part of epidemiological studies or for policy assessment, are, however, poorly developed. This paper describes the development and testing of a GIS-based syste...
