Nitrogen dioxide (N02) produced by combustion processes, is a major constituent of ambient air pollution in urban and industrial areas. It also plays a role as an indoor air pollutant and in the workplace. Indeed acute inhalation accidents in the workplace with high concentrations of N02 provided the first evidence of its adverse respiratory effects. Epidemiological studies provided evidence of...

multiple sclerosis (ms) is one of the autoimmune diseases with an unknown cause. the aim of this study was to explore the link between air quality and ms relapses in patients who suffer from ms.this time-series study was conducted on patients registered at the iranian multiple sclerosis society in 2011-2012. they were randomly selected from patients lived in tehran in the last five years, and h...

This Policy Position Statement outlines the technical challenges involved in the assessment and management of future concentrations of nitrogen dioxide (NO2) in the atmosphere. It notes that NO2 is the pollutant responsible for most breaches in European standards for air quality in the UK and that, as a result, a robust evidence based approach is required to assess future concentrations of this...

Hebei is one of the most air polluted provinces in China. According to the Ministry of Environmental Protection (MEP) for the severe fog-haze month of Jan. 2013, seven of the top ten most polluted cities in China are located in Hebei Province. In this study, the air pollution history and status of the Hebei Province are reviewed and discussed, using the governmental published Air Pollution Inde...

Urban air quality, and its variability in space and time, is a critical issue for human exposure and health related studies. In this work, we investigated the intra-urban distribution of SO2, NOx, NO2, Benzene, Toluene, and Xylenes in ambient air in one of the world’s most polluted cities, Lanzhou, China. Measurements were contemporarily carried out at forty locations in four seasonal campaigns...

A British research team has recently compared the cost-effectiveness of different measures to reduce fine particulate matter (PM10) pollution in London. The authors used the Urban Scale Integrated Assessment Model (USIAM). This software tool enables to bring together data on air pollutant sources, their respective contributions to atmospheric concentrations, and human exposure, together with in...

This paper presents a design of models for common air quality index prediction using computational intelligence methods. In addition, the sets of input variables were optimized for each air pollutant prediction by genetic algorithms. Based on data measured by the three monitoring stations of Dukla, Rosice and Brnenska in the Czech Republic, the models were designed to predict air quality indice...

Limiting global temperature increases to 1.5 °C while respecting ‘the right health’ requires substantial reductions in Short-Lived Climate Pollutants (SLCPs), including methane, black carbon and hydrofluorocarbons, co-emitted air pollutants. This study evaluates the inclusion of SLCP pollutant mitigation within Nationally Determined Contributions (NDCs) that were submitted between 2015 2022. Be...

The quick growth of vehicles is due to fast urbanization in mega cities during last decades. This phenomenon has serious impacts on air quality, as emission from mobile vehicles is the major source of air pollution. As a result, any attempt to reduce the emitted air pollutants is needed. This study aims at improving the fuel quality in transporting system with particular emphasis on taxis in Te...
