New techniques for the design of air pollution monitoring networks : Experience of the nitrogen dioxide in Madrid (1991)
A new approach for the design of NO(2) monitoring networks was applied in Madrid by means of two methods for the assessment of two component test-networks: a mobile laboratory to evaluate the local pollution network in the immediate vicinity of emissions by traffic, and a passive method using 192 diffusion tubes distributed over the city to evaluate the background pollution network, with the limit value of the directive related, in both cases, to the duration of the survey. The siting of the NO(2) stations of the Madrid network, mostly located near traffic, was in agreement with the criterion of measuring the maximum pollution but proved to be too rigorous to assess the eventual exposure of the citizen. The working group advised that some of the traffic orientated stations be moved to residential areas in order to verify the exposure criteria. It also advised the installation of one station at the airport where the guide value was exceeded, as well as one in a green area where a minimum of concentration was observed.
