Abstract Information :
The Air Quality Directive published by the World Health Organization (WHO) in 2021 clearly indicates the danger of air pollution to human health. In the Green Deal, the European Commission committed to further improving air quality and aligning EU air quality standards more closely with WHO recommendations. A new European Air Quality Directive (EU-AAQD) has now set new and significantly stricter limit values for PM10 and PM2.5, which must be complied with by 2030 at the latest. For the first time, the EU-AAQD also makes the measurement of UFP (ultrafine particles, particle diameter < 0.1 μm) as well as gaseous air pollutants and greenhouse gases such as ammonia (NH3) and methane (CH4) mandatory. SUPERSITES In addition to the technical expansion of existing measuring stations, new measuring stations, so-called supersites, must also be set up, the number of which is based on the number of inhabitants of the respective member state. At more than 45 of these supersites, simultaneous measurements of aerosols of all sizes as well as gaseous precursor substances such as NH3 are intended to improve the understanding of the causes of air pollution and to derive the resulting efficient and effective reduction measures. The WHO's recommended long-term target of 5 μg/m³ for PM2.5 takes into account that there is no known limit for particulate matter below which it is no longer harmful to health. DURAG GROUP - PROVIDER OF HIGH-PRECISION MEASUREMENT TECHNOLOGIES The newly added air pollutants and the significant reduction of existing limit values require very powerful and high-precision measuring instruments with low detection limits. The DURAG GROUP is known worldwide for the development and sale of high-precision and high-performance measuring instruments for the areas of process and environmental monitoring, combustion and safety as well as tunnel and traffic monitoring. The measuring devices for gaseous air pollutants ProCEAS AIR (AP2E), as well as the measuring devices for particulate matter EDM 280 (GRIMM Aerosol Messtechnik GmbH and UFP (SMPS and CPC) cover the entire size range of aerosols (100 μm to 0.001 μm) as well as gaseous air pollutants such as NH3 and CH4. By using the best possible measurement components and a patented combination of low pressure sampling (LPS) and optical feedback cavity enhanced absorption spectroscopy (OFCEAS), ProCEAS Air instruments can continuously determine ammonia and methane in the ppb range in real time. The new and EN 16450 certified optical fine dust measuring device EDM 280 can reliably distinguish 0.1 μg/m³ from 0 and has set a new benchmark in terms of measurement performance. In addition to the determination of particle masses as TSP, PM10, PM2.5, PM1 and PMcoarse, it also determines the particle size distribution in 72 size classes at the same time, thus enabling profiling of particulate matter in real time. These unique measurement capabilities are crucial for the implementation of the new EU-AAQD, as the new regulations and the PM2.5 long-term target described above are almost impossible to record with gravimetric samplers or devices based on beta-gauge principles. WORLDWIDE IMPACT OF THE NEW EU AAQD Since the new WHO recommendations apply worldwide, it can be assumed that the EU-AAQD adopted by the EU and coming into force in 2030, as well as the limit values and measurement requirements contained therein, will also come in a similar form in other regions worldwide. DURAG GROUP offers the entire package from the measurement devices to data storage, evaluation and visualization.
