Results of the Air Quality Monitoring Campaign in Szeged, Rerrich Béla square

Location: SZEGED, Rerrich Béla square Coordinates of the AQM station: 46°144998 N, 20°085308 E altitude 84 m Start on: 28th June 2012 End on: 5th July 2012 Experts: dr.ing. Francisc Popescu, dr.ing. Nicolae Lontis Overview of the monitoring site:

Located in Central Europe, Szeged is the third biggest city in Hungary, lies on Hungary's south-eastern border, just south of the mouth of the Maros River on both banks of the river Tisza. It is about 171 km South of Budapest on the M5 highway. It is the lowest elevation city in the country and is known as the "City of Sunshine", because it has the highest number of sunny days throughout the year. Szeged is the main city in Csongrád County and serves as a commercial and cultural center of the region. According to the 2011 data, the city's population was around 170.000. Today's Szeged is an important university town and a popular tourist attraction. In the summer season (1 June - 15 September) a tourist information pavilion is located at the Széchenyi Square.

The name Szeged might come from an old Hungarian word for corner (szeg), pointing to the turn of the river Tisza that flows through the city. Others say it derives from the Hungarian word sziget which means 'island'. Others still contend that szeg means 'dark blond' (sötétsz kés) – a reference to the color of the water where the rivers Tisza and Maros merge. Szeged and its area have been inhabited since ancient times. Ptolemy mentions the oldest known name of the city: Partiscum. It is possible that Attila, king of the Huns had his seat somewhere in this area. The name Szeged was first mentioned in 1183, in a document of King Béla III. Today the inner city of Szeged has beautiful buildings and wide avenues. This is mainly due to the great flood of 1879, which literally wiped away the whole town (only 265 of the 5723 houses remained and 165 people died). Emperor Franz Joseph visited the town and promised that "Szeged will be more beautiful than it used to be". He kept his promise. During the next years a new, modern city emerged from the ruins, with palaces and wide streets. (source: http://en.wikipedia.org/wiki/Szeged) Monitoring results.

The mobile laboratory is equipped with reference point instruments for major pollutants (SO2, O3, NOx, CO, CH4, NMHC, THC and PM10). Meteorological sensors (wind speed and direction, air temperature, pressure and humidity) are mounted around the mobile laboratories. The following pollutants have been continuously measured, with 10 second resolution, over the entire measuring episode with high precision equipment: SO2 measured with HORIBA APSA370 instrument, measurement principle is UV

fluorescence, reference method: EN 14212:2005. The combined measurement uncertainty is U = 1.76 % for recorded values;

NO, NO2 and NOx measured with HORIBA APNA370 instrument, measurement principle is chemiluminescences, reference method: EN 14211:2005. The combined measurement uncertainty is U = 2.06 % for recorded values;

O3 measured with HORIBA APOA370 instrument, measurement principle is UV photometry, reference method: EN 14625:2005. The combined measurement uncertainty is U = 6.98 % for recorded values;

CO measured with HORIBA APMA370 instrument, measurement principle is NDIR (Non Dispersive Infrared), reference method EN 14626:2005. The combined measurement uncertainty is U = 4 % for recorded values;

CH4, NMHC and THC measured with Horiba APHA370 instrument, measurement principle is FID (flame ionization detection), reference method EN 12619:2002. The combined measurement uncertainty is U = 0.9 % for recorded values;

PM10 (suspended particles, fraction PM10), TSI DUSTTRACK, measurement principle is light scattering / laser.

The equipments are part of the air quality monitoring mobile laboratory and procedures used are in full compliance with ISO/CEN 17025:2005 standard for quality assurance in analytic laboratories. The laboratory is the property of “Politehnica” University of Timisoara and more details and information’s (including certifications) can be found on www.mediu.ro Linde and DKD (Deutsche Kalibrierdienst) calibrations gases (NO, SO2, CO, CH4 in N2) were used.

From the data presented in this report we can observe that, with the exception of PM10, for the Szeged, Rerrich Béla tér location the concentrations of all relevant pollutants is fitted under the EU air quality standards. The location was chosen in order to obtain an overview of the background pollution in the central Szeged municipality area, central but far from city road traffic. The absence of road traffic can be observed from figures 1 and 2, as no variations for NOx and CO were recorded. Analysing figures 3 and 4 one can observe that PM10 allowable concentration, 50 µg/m3, were exceeded constantly, presenting a serious concern and requiring further investigations.
