First evaluation of a novel screening tool for outlier detection in large scale ambient air quality datasets
Systematic collection of long term meso- to large-scale datasets of ambient air quality provides an indispensible means for air pollution monitoring. However, the quality of these monitoring data depends on the chosen method of measurements and the QA/QC procedures applied. We present the first version of a prototyped screening tool for the automatic detection of outliers in large data volume ...

Air pollution monitoring for mines: a solution for cost effective measurements
Air pollution is one of the main environmental problems to be addressed by the EU. In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO2, SO2 and NOx) concentrations in air. Many cities are not able of meeting the implemented EU ...

Synergetic use of TERRA/MODIS imagery and meteorological data for studying aerosol dust events in Cyprus
This paper presents the results from the analysis of TERRA/Moderate Resolution Imaging Spectrometer (MODIS) images for the detection and mapping of particulate air pollution in Cyprus. For this purpose, a set of selected air pollution events for the year 2002 was used, mainly associated with dust transported over the area from the surrounding deserts. The results depict the potential of the use ...

Two impact related air quality indices as tools to assess the daily and long-term air pollution
The methodology of the recently developed Daily Air Quality Index (DAQx) and Long-term Air Quality Index (LAQx) is explained. Both indices consider air pollutants frequently monitored at long-term stations within official air pollution control networks. Therefore, they enable an assessment of the integral air pollution, which reflects the ambient air consisting of a mixture of air pollutants more ...

Cysteine synthesis in Scorpiurum circinatum as a suitable biomarker in air pollution monitoring
Heavy metals enter ecosystems by both natural and anthropogenic processes. An excess of metals in the environment damages plant metabolism, leading to oxidative stress in the cell. Most metal ions present in the cell are bound to low molecular mass ligands. The major types of S-containing ligands involved in metal binding are derived from cysteine. The authors show, for the first time in ...

Application of atmospheric dispersion models to evaluate population exposure to NO2 concentration in Buenos Aires
Chronic or repeated exposure to low concentrations of NO2 may increase the incidence of respiratory infections especially in the most sensitive persons. Air pollution monitoring data obtained in Buenos Aires City reveal that sometimes NO2 Air Quality Guidelines (AQGs) recommended by the World Health Organization (WHO) is exceeded. We estimate hourly background concentrations (Ch) of NOx ...
