TL;DR: In this paper, the authors investigated the distribution patterns of traffic-related pollutants near a viaduct having various infrastructures and found that the pollutant distribution profiles behind both noise barriers and combination barriers (i.e., solid noise barrier plus tree vegetation) are characterized by a novel, unimodal mode whereby the UFP and PM2.5 concentrations first increased and then decreased.

TL;DR: In this article, an ANN trained with a back propagation algorithm is used to estimate the well known pollutants, from readily observable local meteorological data, with good accuracy of approximately 96%.
Abstract: The lack of environmental data is a common feature of many developing countries. This is fact in Egypt, where air quality is beginning to be systematically monitored in some places of the country. To overcome these problems, the need for accurate estimates of air quality levels becomes evermore important. To achieve such prediction tasks, the use of artificial neural network (ANN) is regarded as a cost effective technique superior to traditional statistical methods. In this paper, ANN trained with a back propagation algorithm is used to estimate the well known pollutants, from readily observable local meteorological data. The results indicate that the ANN model predicted air pollutant concentrations with good accuracy of approximately 96%. K e y w o r d s: air quality, pollutants, artificial neural network

TL;DR: In this paper, the authors investigate respirable suspended particulate matter (RSP) concentration in selected primary schools with different surrounding human activities, and establish statistical relationships between indoor and outdoor air pollutant concentrations in each selected schools in Kuala Terengganu.
Abstract: Studies have found that indoor air pollution affects human, especially children and the elderly, more compared to ambient atmospheric air. This study aims to investigate respirable suspended particulate matter (RSP) concentration in selected primary schools with different surrounding human activities, and to establish statistical relationships between indoor and outdoor air pollutant concentrations in each selected schools in Kuala Terengganu. Failure to identify and establish indoor air pollution status can increase health problems for these young students and degrade their learning environment and comfort. Indoor air quality (IAQ) parameters in seven primary schools were conducted during the monsoon season of August 2008 until March 2009. Ineach classroom, RSP, air velocity, relative humidity and temperature were monitored during school hours, and a complete walkthrough survey was completed. Results show a statistically significant difference for the six IAQ parameters between the seven schools at the 9...

Journal ArticleDOI
TL;DR: In this paper, the authors analyzed the air pollutant level in the city of Rome in order to analyse the emissions from di_erent sources, and the pollutant exceeds the limit of the Directive 2008/50/EC, the main legislation about ambient air quality, was analyzed for the period taken into account.
