Mesoscale controls on particulate matter pollution for a mega city in a semi-arid mountainous environment: Tehran, Iran

Tehran, the mega-city capital of Iran, suffers from high concentrations of PM10 throughout the year. Emissions from transport combined with mesoscale atmospheric features related to the mountainous terrain lead to a distinctive diurnal pattern in concentrations. Air quality data from monitoring stations show that the highest concentrations of PM10 are in the morning and evening periods, ...

Atmospheric particulate matter in the city of Sao Carlos/SP, Brazil

This paper presents experimental data and source apportionment simulations on particulate matter (PM10 and PM2.5) in the atmosphere of Sao Carlos/SP, Brazil. Both a Hi-vol sampler equipped with glass fibre filters and a Dichotomous sampler with nucleopore filters were used. The collected material was analysed for total carbon, using a thermometric method, and for traces of several chemical ...

Lisbon air quality forecast using statistical methods

Ozone and particulate matter levels in Southern European countries are particularly high, exceeding the established limit values, and the information and alert thresholds (in the case of ozone). Therefore, it is relevant to develop a good prediction methodology for the concentrations of these pollutants. Statistical models based on Multiple Regression (MR) analysis and classification and ...

Investigation of indoor/outdoor air pollutants at the shopping malls in Wuhan

Indoor air quality was investigated at eight shopping malls in Wuhan. Results demonstrate that there are different concentrations of CO2 and HCHO at different floors of a shopping mall. Even at different merchandise zones of a floor for the same mall, there are apparent variations in the concentrations of CO2 and HCHO. These findings should be considered in designing air-conditioning systems. The ...

Wavelet–based models for air pollution modelling around coal mining sites in Jharkhand for 1, 3 and 5 day lead time

Coal dust is a major cause of air pollution in areas around opencast coal mining sites. Prediction of ambient concentration of pollutant should be known to implement any control techniques or to install any control equipment. Combining adaptive network based fuzzy inference system (ANFIS) and linear regression (LR) with discrete wavelet transform (DWT), two types of hybrid models were developed ...

Seasonal apportionment of the sources of ambient air particulates in the city of Trieste

A PCA/APCS model was applied to PM2.5 data, which were collected for the Svevo and Muggia districts of the City of Trieste. The sampling campaigns covered the winter and summer periods of 2006. The set of investigated species comprised major inorganic ions, organic and elemental carbon and several Polyaromatic Hydrocarbons (PAHs) that were considered as probable or possible carcinogens by ...

Modelling long-term averages of local ambient air pollution in Oslo, Norway: evaluation of nitrogen dioxide, PM10 and PM2.5

Large seasonal variations in climate as in Norway give challenges for air pollution modelling, especially of Particulate Matter (PM) that seldom has been evaluated. The EPISODE model calculated ambient concentrations of nitrogen dioxide (NO2), PM with diameter Keywords: evaluation, modelling, long-term averages, ambient air pollution, nitrogen dioxide, particulate matter, air quality, ...

Traffic emission effects on ambient air pollution by PM2.5–related PAH in Upper Silesia, Poland

The ambient concentration of particle–bound polycyclic aromatic hydrocarbons (PAHs) was investigated in two industrial towns in Upper Silesia, Poland. The 24 h samples of PM2.5 (particles with aerodynamic diameter ≤ 2.5 µm) were collected simultaneously at busy roads (or crossroads) and at an urban background site. Additionally, the samples were collected during the heaviest traffic density (rush ...

Plantwide Applicability Limits (PALs): A Legitimate Alternative to Major New Source Review Permitting

Plantwide Applicability Limits: A Legitimate Alternative to Major New Source Review Permitting. There have been a number of recent developments regarding U.S. EPA"s interpretation of the major New Source Review (NSR) air permitting rules that are related to the NSR Reform provisions of December 2002. When these new interpretations are considered in combination with the promulgation of new, more ...

Lisbon air quality: evaluating traffic hot-spots

This paper presents an air quality study in an urban traffic hot-spot in Lisbon, Portugal, by comparing the atmospheric pollutant concentrations obtained by a numerical model with measured values. Results indicate that the mean variation of particle and gaseous concentrations followed the traffic flow rate, evidencing the occurrence of PM10 concentrations greater than the respective air quality ...

Impact of meteorological modelling on air quality: summer and winter episodes in the Po valley (Northern Italy)

The Po–valley in Northern Italy has been identified as a hot spot area in Europe where pollutant levels are expected to remain problematic in the years to come. High anthropogenic emissions in combination with frequently occurring stagnant atmospheric conditions cause very high concentrations of pollutants. Sensitivity tests for one winter month have shown that the nudging of observational data ...

On the Ionization of Air for Removal of Noxious Effluvia

Abstract—Recent developments in the application of controllable air ionization processes that apply dielectric-barrier discharge devices to generate nonthermal plasmas have led to applications for chemical and biological decontamination in indoor air environments. These include significant reductions in airborne microbials, neutralization of odors, and reductions of specific volatile ...

A special issue of JAW&MA supporting key scientific and policy- and health-relevant findings from EPA`s particulate matter supersites program and related studies: an integration and synthesis of results

The U.S. Environmental Protection Agency (EPA) initiated a major air quality program in 1998 referred to as the Particulate Matter (PM) Supersites Program. The overall goal of the program was to improve our understanding of source/receptor relationships and atmospheric processes leading to PM accumulation on urban and regional scales, and thus, provide the scientific underpinning for modeling and ...

Trends of lead in suspended particulate matter in Zagreb air

Monitoring of lead in Total Suspended Particulate Matter (TSPM) started in Zagreb, Croatia in 1971 at three measuring sites. Monitoring of lead concentrations in PM10 started in 1999. This paper presents the trends of annual mean values for lead concentrations in TSPM and in PM10 particles. The obtained data showed a decreasing trend of lead in TSPM, especially during the last ten years when the ...

A wood-strand material for wind erosion control: Effects on total sediment loss, PM10 vertical flux, and PM10 loss

Fugitive dust from eroding land poses risks to environmental quality and human health, and thus, is regulated nationally based on ambient air quality standards for particulate matter with mean aerodynamic diameter 10 µm (PM10) established in the Clean Air Act. Agricultural straw has been widely used for rainfall-induced erosion control; however, its performance for wind erosion mitigation has ...
