Abstract
Particulate matter mass concentrations measured
in the city of Rome (Italy) in the period 2001–2004 have
been cross-analysed with concurrent Saharan dust advection
events to infer the impact these natural episodes bear on the
standard air quality parameter PM10 observed at two city stations
and at one regional background station. Natural events
such as Saharan dust advections are associated with a definite
health risk. At the same time, the Directive 2008/50/EC
allows subtraction of PM exceedances caused by natural contributions
from statistics used to determine air quality of EU
sites. In this respect, it is important to detect and characterise
such advections by means of reliable, operational techniques.
To assess the PM10 increase we used both the “regionalbackground
method” suggested by EC Guidelines and a “local
background” method, demonstrated to be most suited to
this central Mediterranean region. In terms of exceedances,
the two approaches provided results within 20% of each
other at background sites, and at 50% of each other in traffic
conditions.
