BACKGROUND We conducted a meta-analysis to evaluate the association between traffic-related air pollution and lung cancer in order to provide evidence for control of traffic-related air pollution. METHODS Several databases were searched for relevant studies up to December 2013. The quality of articles obtained was evaluated by the Strengthening the Reporting of Observational Studies in Epidem...

BACKGROUND Numerous epidemiological studies have shown that air pollution due to both industry and heavy traffic has short- and long-term effects on health. The study was carried out in an industrial area with heavy urban and motorway traffic in the Province of Genoa (Italy). METHODS The study was carried out from June 2005 to July 2008. An epidemiologic study was conducted by monitoring an e...

Mega cities in South Asia are an epitome of traffic snarls and resulting vehicular pollution. Dhaka, a center of polity and economy in Bangladesh, is no exception. This study is focused on the measurement of air pollution levels at traffic congestion and road in Dhaka City. The aim of this paper is to discuss the vehicle engine emissions and the technologies and methodologies available to help ...

Air pollution has become one of the main problems of cities. Among the sources of air pollution, vehicular traffic plays an important role. Planning for efficient management and control of the air pollution caused by vehicular traffic requires accurate information on spatio-temporal dispersion of the pollutions. This research studies 3D spatio-temporal dispersion of NOx pollution caused by vehi...

BACKGROUND Air pollution contributes to mortality and morbidity. We estimated the impact of outdoor (total) and traffic-related air pollution on public health in Austria, France, and Switzerland. Attributable cases of morbidity and mortality were estimated. METHODS Epidemiology-based exposure-response functions for a 10 microg/m3 increase in particulate matter (PM10) were used to quantify the...

Several pathological conditions have all been associated with a higher release of atmospheric pollutants. There is growing evidence that oxidative stress may represent one of the agents involved in the initiation and/or progression of many of these pathologies. The aim of the present study was to evaluate the effects of short-term dietary supplementation with a standardised red orange extract (...

This vision of the future is motivated by the increasing traffic congestion around our densely populated metropolitan areas. There is no need here to reference the numerous studies on traffic safety and pollution carried out by governmental agencies over the years or to bring forward accident, carbon dioxide, and driver-stress figures. Everyone that has been in a large city in rush hour has mos...

Using mathematical simulation, distribution of concentration of harmful substances NOx at Rustavely Avenue, the crossroad of David Agmashenebeli and King Tamar Avenue, where traffic is congested, and for the whole territory adjoined to the crossroad have been studied. In addition, there have been investigated influences of traffic-lights at streets' intersections on the growth of concentration ...
