Article 1.3.4.1.

The Flanders Environment Agency (VMM), Air, Environment and Communication Division, is recognised for the development and use of measurement networks for the measuring of the pollution of the ambient air and the monitoring of the air quality as stated in Articles 2.2.6 and 10.2.4 of the Decree of 5 April 1995 concerning the general provisions related to environmental policy. This concerns the monitoring and the measuring of the pollution of the ambient air within the framework of the following measurement networks:

1 telemetric measuring network for air, for the monitoring of progress of the general air quality for air-polluting substances, in particular: SO2, NO, NO2, O3, CO, CO2, BTEX, VOS, sampling and gravimetric determining of dust particles, the continuous measurement of dust particles with specific size characteristic;
2 local measurement networks in areas with an acute local problem of air pollution, in particular: SO2, H2S, organic sulphur compounds, NO, NO2, O3, CO, CO2, BTX, VOS, sampling and analysis of black smoke according to the OECD method, sampling and gravimetric determining dust particles, the continuous measurement of dust particles with specific size characteristics;
3

mobile measurements of air pollution for air-polluting substances, in particular: SO2, H2S, organic sulphur compounds, NO, NO2, O3, CO, CO2, BTX, VOS, total hydrocarbons and total dust content;

4 measuring for heavy metals in suspended particulate matter, in particular: As, Cd, Cu, Ni, Pb, Sb and Zn;
5 measuring for heavy metals in falling dust, in particular: As, Cd, Cu, Ni, Pb and Zn;
6 deposition network acidification for the determination of inorganic substances in the ambient air, in dry, wet and total deposition, in particular: ammonia, ammonium, calcium, chlorides, fluorides, potassium, magnesium, sodium and sulphates;
7 measurement networks for the determining of organic substances in the ambient air, in dry, wet and total deposition, in particular: PAHs, nitro-aromatic hydrocarbons, VOC and HVOC;
