“precursors”. Since they represent by far the most dangerous pollutant in EU today,
working for their reduction is extremely complex since the problem must be tackled
considering a large area and not a single source and that one has to operate on the
precursors, knowing that meteorology may alter the picture in different ways.
Given this complex situation, EU has issued a number of directives to define
limits concentration on ambient air and indications on how to attain such results. As
is apparent from the preamble to Air Quality Directive 2008/50/EC (AQD),
