That information is essential to judge the enhanced levels in more polluted areas (such as urban background locations, air pollution hotspots, industry related locations or traffic related locations), assess the possible contribution from long-range transport of pollutants, support source apportionment analysis and for the understanding of specific pollutants such as particulate matter. It is also essential for the increased use of modelling applications also in urban areas. Measurement of PM2,5 shall include at least the total mass concentration and concentrations of appropriate compounds to characterise its chemical composition. At least the list of chemical species given below shall be included. SO4 2– | Na+ | NH4 + | Ca2+ | elemental carbon (EC) NO3– | K+ | Cl– | Mg2+ | organic carbon (OC) Measurements shall be taken in urban background locations and rural background locations in accordance with Annex IV. The main objectives of measurements of ozone precursor substances are to analyse any trend in ozone precursors, to check the efficiency of emission reduction strategies, to check the consistency of emission inventories, to support the understanding of ozone formation and precursor dispersion processes, as well as the application of photochemical models, and to help attribute emission sources to observed pollution concentrations. Measurement of ozone precursor substances shall include at least nitrogen oxides (NO and NO2), and, as appropriate, methane (CH4) and volatile organic compounds (VOC). The selection of the specific compounds to be measured shall depend on the objective sought and may be complemented by other compounds of interest. Member States may use the method which they consider suitable for the objective sought. The reference method as specified under Annex VI applies for nitrogen dioxide and oxides of nitrogen.

The objective of such measurements is to ensure that adequate information is available at locations where high concentrations of UFP occur that are mainly influenced by sources from air, water or road transport (such as airports, ports or roads), industrial sites or domestic heating. The information shall be appropriate to judge on enhanced levels of UFP concentrations from those sources. UFP. Sampling points shall be established in accordance with Annexes IV and V at a location where high UFP concentrations are likely to occur and downwind of the main sources within the relevant predominant wind direction of those sources.
