PARTICULATE MATTER AND AIR QUALITY
As can be seen in the graphs from the IJmond air quality data report, the PM10 and PM2.5 concentrations in IJmond have been declining for some time, as in the rest of the Netherlands. At the moment, the EU standards for the annual average PM10 and PM2.5 concentrations are amply met. The pink line is Wijk aan Zee. You can see that it is close to the WHO guideline value (2005) (The SLA initially focuses on achieving the WHO guideline values (2005) for particulate matter (PM10 & PM2.5) in 2030)). It is far below the current EU standard. Our measures from Roadmap Plus will help to further reduce the contribution to the PM10 concentration in IJmond. The graph with the number of daily average values >50µg/m3 shows the number of days on which the daily average PM10 concentration is exceeded. This shows that this number has decreased sharply in recent years, which is also reflected in the air quality.
Our measures from Roadmap Plus will help to further reduce the contribution to the PM10 concentration in IJmond. Partly depending on the contributions from other sources in IJmond, it might be possible to achieve the air quality at this WHO value (average annual concentration) in residential areas. However, it is important to realise that Tata Steel has only a minor influence on the PM10 concentration in the area (20-25%) (calculated using data from Verspreidingsberekeningen ZZS bij Tata Steel).
