Determinating the influence of different PM 10 sources on air quality in Ljubljana basin with CALPUFF dispersion model
Ljubljana has an unfavourable geographical location in the basin, almost entirely surrounded by high hills. Winds in the basin are often weak and situations with temperature inversion are very frequent, therefore, many PM 10 daily limit value exceedances were observed in 2011. The Directive 2008/50/EC (EU, 2008) requires member states to adjust or provide new air quality plans in order to ...

Air Pollution and Vulnerability: Solving the Puzzle of Prioritization
While ambient air pollution levels in excess of prescribed health standards are generally unacceptable, the exceedance is even more serious in areas where people reside. Vulnerability caused by poverty, disease, lack of education, and poor living conditions exacerbates the problem. Air quality management plans identify prioritized strategies for improved air quality independent of consideration ...

CPCB to Validate Sensor-Based Air Quality Monitoring System??
Rapid economic growth has brought many benefits to India; but the environment has suffered, exposing the population to serious air pollution. The consequences of pollution have led to poor urban air quality in many Indian cities. The air pollution and the resultant air quality can be attributed to emissions from transportation, industrial and domestic activities. Due to pollution, the ambient ...

The Italian debate on the role of regulatory models in the framework of the new European directives on air quality
This paper addresses some topics from the debate in Italy about the role of regulatory models in the management of air quality. It appears that an effective use of dispersion and transformation models cannot take place unless some 'external' (i.e. prejudices against models) as well as 'internal' (i.e. actual deficiencies in model evaluation and use) issues are overcome. Models play an important ...

Low Emission Zones
What is a Low Emission Zone (LEZ)? An LEZ is a defined area within a city where access to the most polluting vehicles is restricted to reduce emissions and improve air quality. These types of restrictions are often set in large cities, where pollution due to traffic has a significant impact on health and environment. Although the idea of an LEZ was first set up in Stockholm in ...
