quality: signs of improvement Despite the significant improvement in air quality , it is essential to continue to develop effective and coherent policy undertaken in recent years to adapt to the rules laid down by the law of entries Ticino in particular those relating oxides of nitrogen, particulate matter and ozone. This is the conclusion of the 2006 air quality report released today on the Canton Ticino in Bellinzona. The contents have been exposed by the Director of the Department Marco Borradori.
The traffic sector, in the canton of Ticino that links between Northern and Southern Europe, remains a major source of air pollution, where the benefits of technical measures liable to be overturned by increasing volumes of traffic and freight. This is one of the basic facts that emerge from the Plan.
According to the Plan 's air pollution can be reduced through two strategies: the technical requirements that act on specific emissions of polluting activities, and scaling. The emissions can be reduced by adjusting the emission factors with technical measures and by reducing fuel consumption and mileage, eco-incentives and measures of a legal nature.
To give greater effect to the reorganization plan were also adopted regional plans. The plan to restructure Air Lugano (PRAL) was approved on 1 October 2002 and must be implemented in stages to coincide with the opening of the Gallery Vedeggio-Cassarate, by 2008-2010. That for Mendrisio (PRAM) has been adopted by the State Council in March 2005.
Ticino In the main air pollutants are nitrogen dioxide, particulate matter and ozone. These three pollutants are generated by vehicular traffic. In the canton Ticino air pollution is characterized by two specific phenomena: a winter period (from January to March) with frequent thermal inversion conditions that prevent the exchange of air masses and thus generate high concentrations of particulate matter (smog winter) and a summer smog period marked by high concentrations of ozone.
Measures against trafficking are directed rather to stem the rise the volume of miles driven by acting at different levels: PLANNING, management and traffic calming, promotion of public transport and economic incentives. The new measures of a technical nature relating to traffic aimed at curbing rising emissions of particulate matter generated by diesel vehicles in particular. This was followed, and close the package of measures, the measures "subsidiary" for containing transboundary air pollution and monitoring of the measures envisaged by the new PRA.
transport policy is therefore a crucial piece of the security strategy of 'air . Its main figure the development of public transport as an alternative to private motorized transport , both for the movement of people, both for the transfer of freight from road to rail. In this sense, are also those measures designed to influence the location of major traffic generators on the basis of connection to public transportation, planning tools and incentives for a while. More effort should also be bestowed in relation to construction of bicycle paths and pedestrian walkways be used for local transport
