This study derives from the need to evaluate the impact on the urban air quality of two-wheeler vehicular class. Mopeds and motorcycles, in fact, are increasingly used in recent years, representing a great share of motor-powered vehicles in urban environment. This paper is finalized at the examination of the emissions of the last generation motorcycles, contributing broadly to extend knowledge ...

In order to perform a study of the carcinogenic potential of polycyclic aromatic hydrocarbons (PAH), benzo(a)pyrene equivalent (BaP-eq) concentration was calculated and modelled by a receptor model based on positive matrix factorization (PMF). Nineteen PAH associated to airborne PM10 of Zaragoza, Spain, were quantified during the sampling period 2001-2009 and used as potential variables by the ...

To help systematically lower anthropogenic Greenhouse gas (GHG) emissions, accurate and precise GHG emission prediction models have become a key focus of climate research. The appeal is that the predictive will inform policymakers, hopefully, in turn, they bring about systematic changes. Since transportation sector constantly among top contributors, especially populated urban areas, substantial...

Detailed on-line measurements of city air quality are necessary to support compliance with air quality standards and emission strategy developments and to inform both policy makers and the general public in a timely manner. Current approaches to pollution monitoring, however, rely on very small numbers of stationary nodes. Providing detailed air quality information is a particularly hard challe...

This study identified concentrations, molecular distributions, toxicities, and sources of polycylic aromatic hydrocarbons (PAHs) in road dust from different areas of Ulsan, the largest industrial city in Korea. The total PAH concentrations in industrial areas were dependent on industrial emissions and vehicular exhaust, while those in urban areas were mainly dependent on traffic density, sampli...

A general proecological urban road traffic control idea for the street canyon is proposed with emphasis placed on development of advanced continuum field gasdynamical (hydrodynamical) control model of the street canyon. The continuum field model of optimal control of street canyon is studied. The mathematical physics' approach (Eu-lerian approach) to vehicular movement, to pollutants' emission,...

1 Abstract A generic proecological traffic control model for the urban street canyon is proposed by development of advanced continuum field hydrodynamical control model of the street canyon. The model of optimal control of street canyon dynamics is also investigated. The mathematical physics' approach (Eulerian approach) to vehicular movement, to pollutants' emission, and to pollutants' dynamic...
