Possible Causes of Elevated Ambient CO2 Concentration in the City of Pardubice and its Surroundings
Authors: , , , ,
Abstract: This paper presents the results of monitoring of air pollution concentrations of CO2 in the time period from October 2010 to April 2011. The measurement was carried out with the help of portable analyser ECOPROBE 5, which operates on the principle of measurement of IR radiation absorption. The results obtained were given more precision by means of calculations involving the effect of sensor temperature on the intensity of entering radiation. It was found out that the average CO2 concentration in air in the above-mentioned time period was 400 ppm which is 20 ppm higher than the planet-wide average. Further research of the measured data and its comparison with atmospheric dispersion model study indicate that the elevated concentrations are probably caused mostly by increasing traffic intensity. Large industrial sources in the vicinity were found to have only marginal influence on the ambient CO2 concentrations.
