Abstract:
We present an objective methodology for selection of the minimum number of sampling sites required to register the highest concentration values of air pollutants emitted from a continuous point source. The methodology is based on the analysis of 1 hour concentration values above a threshold value estimated by atmospheric dispersion models. The number and location of the air monitoring stations are determined according to the likelihood that a station can measure high concentration values in accordance with model results. The efficiency of the monitoring network design depends on the accuracy of the considered dispersion model, a low interannual variability of atmospheric conditions and the number of samplers. Following a brief description of the methodology we detail an application to design an air monitoring network. We apply the ISCST3 atmospheric dispersion model to a point source emission, considering one year of hourly meteorological data. In this example, an approximated value of the efficiency of the network design is 0.475 at best. An objective method for selecting the number and location of air-monitoring stations to measure 1-h high-concentration values of an air pollutant emitted from a single stack is presented, which utilizes the Industrial Source Complex Short Time Dispersion model (ISCST3) and 1 yr of meteorological data over 1-h intervals. The method requires the distribution of the frequency of hourly concentration values higher than a threshold value, which could be the air-quality standard or another selected value. The network accuracy is necessarily related to the model bias in the estimation of the highest concentration values. The methodology is illustrated for an industrial plant with a 43-m high stack, a diameter of 6 m, a stack-gas exit velocity of 16 m/s, a stack-gas temperature of 400 K, and a nitrogen dioxide emission rate of 60 g/s.
