Framework Directive 96/62/EG, Art. 1
General aim is to define the basic principles of
a common strategy to

• define and establish objectives for ambient air
  quality in the
• Community designed to avoid, prevent or reduce
  harmful effects
• on human health and the environment as a
  whole.
• Assess the ambient air quality in Member States
  on the basis of
• common methods and criteria.
• Obtain information on ambient air quality and
  ensure that
• it is made available to the public
• Maintain ambient air quality where it is good and
  improve it in other
• cases.

Important Steps of Assessment Process

• Specification of responsible institutions
• Designation of zones and agglomerations
• Preliminary assessment
• Yearly assessment

10

• National German Legislation and Institutional
• Structure on Air Pollution Protection
• - 1974 Federal Air Pollution Control Act
• - since 1980 Directives of European Community
  (EC)
• - since 1996 new generation of EC-Directives
• Germany
• - 16 Federal States
• - responsible for air quality monitoring and
  assessment
• - co-ordination
• UBA
• State Committee for Air Pollution Protection
  (LAI)
• - National Reference Laboratory

• Preliminary Assessment
• - general aim
• provision of an overview of existing information
  on
• ambient air quality
• basis for planning and implementation of air
  quality
• management
• using representative measurements of pollutants
  for all zones and agglomerations
• if not available, than need of
  - measurements
• - surveys
• - assessments

13

• Preliminary Assessment
• - working steps
• - description of the area (zones,
  agglomerations)
• indication regarding air pollution sources
• - initial assessment / inventory of ambient air
  quality !!!
• - comparison with air quality standards
• Basis for - development of monitoring strategy
  !!!
• - starting point for detailed air quality
  studies

14

• Step Definition / Description of the area
• - Zones and Agglomerations as Basis
• - Demography, Statistics
• -Topography
• - Meteorology, Climate
• - Emission situation

15
Step Initial Assessment of Ambient Air Quality

• using all applicable information sources
• Monitoring networks
• Measuring stations
• Temporary / indicative measurements
• Random sampling measurements
• Screening programs
• Estimations
• Modelling
• very different methods possible!

Step Comparison with air quality standards
Measurements mandatory - In agglomerations
(gtLAT ltLAT if alert threshold) - Maximum level
in zone gtUAT combination of
measurements and modelling possible - Maximum
level between UAT and LAT objective
estimation, modelling - Maximum level lt LAT

17
Development of Monitoring Strategy
- basing on results of preliminary
assessment - monitoring effort depends on
pollution level - criteria defined in
EU-directives
Saxony-Anhalt State Environmental Protection
Agency
18
Criteria for elaboration of monitoring concept
For measurements - location of sampling points
/ stations - minimum numbers of stations (each
pollut.) - reference methods and sampling
techniques - continuous measurement required (as
a rule) - strong data quality requirements For
other assessment techniques, partic. modelling -
spatial resolution for modelling / objective
assessment - reference modelling techniques
