What is Air Quality Management?
An endless loop ofo Ambient Air Quality Monitoring Datao Emission Databaseso Air Quality Modelling Training Evaluation
![Page 6: Tarmo Pauklin Estonian Environmental Research Centre](https://reader036.vdocuments.net/reader036/viewer/2022062321/5681412b550346895dad0c77/html5/thumbnails/6.jpg)
Principle of the system
Dispersionmodelling
Emissions
Meteorologicaldata
Air qualitymonitoring
Calculatedlevels
Checkingemissions
Based on meteorology and emission inventories the levels of air pollutants are calculated using dispersion modelling. Calculated levels are compared with measured values. If calculated and measured values are different the emission sources are checked by measurements.

Progress of the project
As the tender was technically very complicated the preparation and approvement of final Tender Dossier took 17 months (November 2002 – April 2004)
The first draft version of Tender Dossier was sent to Ministry of Finance (MoF) in 14th of November 2002. Analysis of the Tender Dossier was made by the Expert
The deadline for submission of offers for the supply component was on the 28th of June 2004 and there were two tenders. The evaluation of tenders took place in two periods totally from 28th of June until 30 November of 2004
The contract was signed with SMHI on 16 of February 2005
Duration of the project- one year, budget 3,5 MEUR

Passive Samplers
The pollutant is transported to the sorbent by molecular diffusion
Sampling time1 – 4 weeks
SO2, NO2, VOC 145 samplers per
campaign;3 campaigns nationwide

Problematic pollutants in Estonia
Exceedencies of PM10 limit values in Tallinn and in other cities;
In background stations ozone concentrations tend to exceed even new target values during spring and summer months;
In Kohtla-Järve area (oil-shale industry) high levels of specific pollutants are of great concern – hydrogen sulphide, phenols and formaldehyde.

Biggest threats to the system
Quality of the output of the system depends on quality of the input data – main source of the errors is air emission database
Most important partner is county environmental department (inserting and checking new emission data), without adequate emission data activities of the other partners is irrelevant
Long-term financing of the maintenance of the system and accompanying obligations, enacting exact obligations of the parties

Conclusions and lessons learnt
The first nationwide edb is developed (3500 point sources, 2900 road links)
– New type of sources (house holds, traffic, trains, planes) staff Plans & programs Kohtla- Järve, Muuga harbor Drafting action plans for Tallinn agglomeration and Ida-
Virumaa zone inform public about air quality and pollution episodes (
