[CEST2019_00686] Influence of Varying Concentration of Toluene in a Soil Biofilter
by Badilla D.B.

Contaminant concentrations and their variability affect rate of removal of air contaminant in biofiltration. In this study with toluene as the air contaminant, extent of degradation rate at varying concentrations (from 50 to 700 ppm) in terms of elimination capacity (EC) was measured using a soil biofilter run for 215 days. It appears that no inhibition or oxygen limitation was observed at 700 ppm as EC went higher at this concentration reaching 58 g m-3 hr-1.

[CEST2019_00651] Co-creating data based on human nose perceptions to study odour nuisance from an oilseed industry
by Teixeira S., Pereira P., Ferreira F.

Odour nuisance is the second environmental problem with more citizen complaints after noise. This fact and the lack of odour regulation in Portugal led way to develop a bottom-up approach focused on citizens to co-create the analysis. Despite the existence of odour measuring instruments, the human nose is a universal sensor with high sensitivity that allows to assess the impact of discomfort on human receptors.

[CEST2019_00608] Odorous gases monitoring on industrial sites and algae decomposition using Cairsens smart sensors
by Ben Daoud A., Caron A., Akiki R., Aflalo S.S., Laplagne J.

The appearance of natural odors sources (Sargassum beaching events) or odors generated by the human activity (industrial sites) represent a major challenge for municipalities. Combined with intolerance of nuisances by residents, and/or tourists, it forces municipalities and industrial players to manage and control diffused emissions of odors in a more stringent and efficient way.
Hydrogen sulphide (H2S) and ammonia (NH3) have been identified as the main odorous nuisance sources, they also have high adverse effects on health, and therefore they must be monitored and controlled.

[CEST2019_00611] Daily wind gusts in relation to mean daily wind speed and atmospheric circulation
by Deligiorgi D., Philippopoulos K., Granakis K.

An important aspect in the design of wind farms and consequently in wind power production, is the sensitivity of wind turbines to wind gusts. This study aims at estimating the probability of occurrence of daily wind gusts for different atmospheric circulation regimes. The analysis is performed for a 31-year period (1979-2009) for the Hellinikon station in Athens, Greece. The proposed methodology estimates wind gust speed values from the mean daily wind speed observations for a given atmospheric circulation pattern.

[CEST2019_00613] Statistical modeling of meteorological conditions and air pollution over Athens, Greece
by Deligiorgi D., Philippopoulos K., Diamanti A.

The importance of meteorological parameters and topography in determining the air pollution levels in a specific area is well established. The aim of this study is to model the association between air pollution levels and meteorological parameters for a single site in Athens, Greece. The statistical analysis is based on the Multiple Linear Regression (MLR) models for simulating the relationship amongst primary and secondary pollutants (CO, NO, NO2, O3 and SO2) and air temperature, wind speed, relative humidity and atmospheric boundary layer (ABL) depth.

[CEST2019_00438] Impact of traffic management strategies on air quality and health in a Portuguese urban area
by Silveira C., Ferreira J., Lopes D., Miranda A.I.

This paper aims to assess the air quality improvement and resulting health implications in a Portuguese urban area, by testing traffic management scenarios focused on nitrogen dioxide (NO2) emission reduction. To that end, an integrated multiscale modelling system was developed and applied for a typical traffic-activity day using dynamical downscaling to the street level. At this finer scale, the tested scenarios contributed to a reduction of the daily maximum NO2 concentration and health benefits, though the LEZ effect is more felt within its influence area.

[CEST2019_00391] Statistical prediction models for the odour quantificaton in terms of odour concentration: analysis and comparison
by Galang M.G.K., Zarra T., Naddeo V., Ballesteros F.,Belgiorno V.

Measuring odour concentration is a significant step to achieve efficient environmental odour management in continuous, objective and repeatable manner. To deal with this, researchers developed instrumental odour monitoring systems (IOMS) by applying odour monitoring models (OMM) for prediction. At present, limited data are available in the literature regarding the exploration of different prediction models to quantify the odour emissions in terms of odour concentration.

[CEST2019_00394] Advanced instrumental odour monitoring system for the continuous management and control of environmental odour in complex industrial plants
by Zarra T., Meloni M., Naddeo V., Pittoni G., Belgiorno V.

Odour emissions from complex industrial plants may cause potential impacts on the surrounding areas and, as consequence, complaints with the local residents. The identification of specific odour control plan is therefore needed in the plant management. The current challenge is the definition of Instrumental Odour Monitoring Systems (IOMSs) that allow the continuous odour characterization. No regulation or standardized procedure exist at present.

[CEST2019_00184] Biomass burning tracers in urban and rural particles in Silesia - Poland
by Czaplicka M., Janoszka K.

The major tracers are thermal degradation products from the biopolymer cellulose, namely the didehydromonosaccharide derivatives levoglucosan (LG), galactosan (GA) and mannosan (MN) and the resin acid derivative dehydroabietic acid, with minor β-sitosterol. The relative proportions of levoglucosan to mannosan (LG/MN) have been used for source reconstruction of combustion derived byproducts in atmospheric aerosols. Major tracers eg. levoglucosan, galactosan and mannosan were measured at two sites in Silesia region and health resort (Krynica) during winter season 2017/2018.

[CEST2019_00211] The influence of methane emission and hard coal production on air quality and greenhouse effect in 1994-2017 in the Upper Silesian Coal Basin (Poland)
by Dreger M.

The Upper Silesian Coal Basin (USCB) is the largest coal basin in Poland and one of the largest in Europe. It is the most industrialized region in Poland. The main natural resource and energy raw material is hard coal which was produced by 65 mines in the early nineties. The USCB geology is very diverse and not homogeneous. Coal deposits situated in the central, southern and western regions are mostly covered by impermeable Miocene deposits which helped methane (CH4) to accumulate in the past.
