3.2. Country-wise brief summaries

The network and coverage (compounds, spatial, temporal) in each country are briefly summarised in this chapter. Also, shortcomings/gaps (when obvious from the collected information, when it is considered complete) and near-future trends (when information is given) are described.

Only a general summary regarding methods evaluation, data availability and reporting and network description is given immediately below.

 

Methods evaluation: Standard, generally accepted methods, samplers and monitors are used almost exclusively in most networks. These are methods as described e.g. in EU directives, or equivalent. Some countries in eastern Europe (Albania, Bulgaria, Croatia, Estonia, Romania) use to some extent non-standard methods which are not necessary equivalent to methods as described in the directives. Some countries uses advanced methods routinely at some sites, such as DOAS in Finland, Norway and Sweden, and on-line compound-specific VOC analysis in the UK.

Specific information on QA/QC procedures were in general not made available as part of this project.


Data availability: Specific information is missing for many countries, as shown in the Tables 3.2 and 3.3. Non-validated monitor data is, to our knowledge, available at a central data base for one or more networks in the following countries: Austria, Denmark, the Netherlands, UK, Norway, Cyprus.

Validated data are in general available after 1-3 months after measurement, but some countries need longer time, especially for data from manual samplers and for precipitation data.

U.K. has recently made the data from the automatic monitor programme available on-line on Internet. The preliminary data are updated with quality controlled data regularly, after a delay of 2-3 months.


Reporting: The time delay before reports are available varies substantially. Ozone represents a special case. For EU countries, the ozone directive requires that ozone is reported in principle to the public every day.

For local air quality, annual reports are available 4-12 months after the year, depending upon country (see Table 3.2). Some countries or networks issue monthly reports after a much shorter time delay. The reports are written in the national language, but some countries issue summary reports in English as well (e.g. Czech Republic, Slovakia, Slovenia).

 

Network description: Detailed site description is an important background for evaluating representativity of networks and for judging the air quality information from the network correctly. Dedicated reports with detailed site descriptions were available to us from Austria, the Netherlands and Spain. For some other countries, brief descriptions were available within the AQ reports, such as for Sweden, the UK.


EU MEMBER STATES

Austria

The information available to us on air quality monitoring networks is fairly complete.

9 provincial networks are operated, mainly in urban/hot-spot locations, a total of 237 sites. All site categories are well covered. Most cities and larger towns (10) are covered. The national UBA network operates 8 regional sites. In addition, some local industrial networks exist. There is a smog warning system operated in the Vienna, Linz and Graz areas. A large part of the sites are equipped with monitors.

Coverage:
Substantial spatial coverage, with e.g. 135 O3 sites and about 150-200 sites for SO2, NOx, SPM. Acid deposition at 3 (EMEP) sites. CSD compounds (except Pb) and CO are well covered. VOC and H2S is measured at some sites.

Reporting:
For urban/hot spot networks: Province-wise. Available after 3 weeks of new year
For regional UBA sites: National report. Available after 1 month of new year

Trends:
In the course of setting up a monitoring concept for the future Air Quality Protection Act, a review of the currently run monitoring networks is performed that will result in a reduction of monitoring sites for CO, and to a minor extent of SO2, NO2 and SPM, and a relocation of several sites in order to achieve a more homogenous spatial coverage; additionally a monitoring network for lead and benzene is being built up.

 

Belgium

The only information available to us on air quality monitoring networks was from the WHO questionnaire. It is not complete.

Portugal

At the moment there are 84 AQ monitoring stations in Portugal which belongs to the following networks:

  • Private networks associated to large industrial plants. There are 6 networks and the responsible for the measurements are the industries themselves.

  • Local networks, which are 5, associated to urban and/or industrial areas. These networks are managed by Local Commissions for Air Management (CGAs) which are integrated in the Regional Directorates for Environment and Natural Resources (CGA-Porto in the North Regional Directorate, CGA-Estarreja in Center Regional Directorate, CGA-Lisboa and CGA-Barreiro/Seixal in Lisboa e Vale do Tejo Regional Directorate and CGA-Sines in Alentejo Regional Directorate).

  • National network, with 15 stations, have been operated since 1986. Some of these stations also belong to the Local Networks. The national institution responsible for this network is the Meteorological Institute (IM).

  • EMEP network with 5 stations.

  • BAPMoN network with 8 stations.

Coverage:
Substantial. The existing stations cover the main urban areas (cities of Lisboa, Porto, Coimbra, Setúbal and Faro), the industrial or urban/industrial areas (Barreiro/Seixal, Sines and Estarreja) and the areas within the influence of large plants. However, it is still necessary to have more stations in some of these areas, principally in urban sites to obtain a better coverage. There are also some other places which are not yet covered. For these areas there have been made some campaigns for data collection with a mobile station.

Data availability:
National network: available annually. Some data are published daily in newspapers.
Local network: available annually. By demand data from all networks can be provided after validation within a short delay. After all national stations have been connected to the central node, data will be available in near real time.

Reporting:

Sweden

Available info is from a data report on Urban Air Quality, from 1994.

There is an urban network covering 45 cities/towns (66 sites) operated by local authorities. The national network of regional air and precipitation quality includes 49 sites, of which 8 are EMEP sites. The urban network is equipped partly with monitors and partly with manual samplers (about 50 of each). The urban network includes 20 ozone sites with diffusive (passive) sampling on a monthly basis (6 months per year). EMEP includes 6 ozone sites equipped with monitors. Most of the 35 VOC sites are passive BTEX sampler sites. The others (3) are equipped with DOAS instruments.

Coverage : Substantial spatial coverage, but traffic and industrial hot-spot sites are not well represented (3 traffic sites in Stockholm, and no industrial sites). Temporal coverage: Many urban sites are operated only in the six winter months, and O3 only in the summer months.

Data availability : Monitor data in principle available from the local networks, but no delay time given.

Reporting : Annual reports are prepared by The Swedish Environmental Research Institute (IVL). The urban network report for the winter 1995/96 will be published in September 1996. EMEP 1995 data will be available in the spring 1996. Statistic Sweden yearly reports data from cities, in December from the last winter period.

Shortcomings/gaps : Urban air quality is in general not measured during summer, so annual averages can not be given.


United Kingdom

The available information is rather complete, through returned MA 1-2 questionnaire, data reports and other summary documents.

Air quality is monitored through national networks, of which there are 9 at present. The networks are compound/area-type specific, and have in principle a national coverage. Briefly mentioned the networks are (number of sites in brackets): Automatic Urban Network (25), Rural Ozone (15), Automatic VOC (9), Smoke and SO2 (252), NO2 diffusion tube (1,100), Lead etc. (15), Toxic organics (5), Acid dep. (32), Rural SO2 (38). 19 EMEP sites (incl. 16 in the rural O3 programme).

Coverage:
Substantial, both spatially, temporally and compound-wise. 34 cities are covered, and 4 industrial areas.

Methods:
Standard/state-of-the-art/advanced (diffusion tubes for NO2, on-line compound-specific VOC monitoring).

Data availability :
Monitor data are available near-real-time (1-2 hours delay) on an Air Quality Bulletin System on Internet form the Department. of Environment.
Acid dep. data: After 3-6 months.

Norway

The available information is complete, through NILUs involvement.

The urban air quality programme is designed to give data on population exposure, through combined use of monitoring and modelling. The urban network presently consists of 6 urban background sites (in as many cities). The regional background air and precipitation quality network consists of 39 sites (12 EMEP sites), of which 11 has monitoring of NO2, 15 has O3, and 11-13 has major ions. Hourly presentation of data to authorities is in operation in two cities (Drammen and Bergen).

Coverage:
The coverage of the regional network is substantial. The urban network is not yet complete. The urban sites measure only NOx, NO2, PM2.5 and PM10. SO2 conc. is very low, except for in some industrial locations. Most of the urban sites are operated only in the six winter months.

Data availability:
From monitors: near-real-time or daily (depending upon site). Quality controlled data: after one month.
From samplers: Quality controlled data: after 2 months.

Reporting:
Background network: Annual, after 10-12 months.
