『Abstract
Source apportionment analysis was used to identify the factors
contributing to atmospheric pollution at a monitoring location
in the Southeast of Spain, a well documented area with an arid
climate and high insolation favouring two sources of particular
matter: secondary transformation in the atmosphere and resuspension
of crustal dry soils to the air. These conditions are further
complicated by numerous industrial facilities in the area of the
historical city of Cartagena. This paper describes the air quality
of an area which includes a zinc metallurgical industry, a petrochemical
factory, an oil power station, a shipyard and natural phenomena
including African dust transport and resuspension of regional
and/or local crustal materials. Major and trace element concentrations
in PM10 and PM2.5 were determined at two monitoring stations in
Cartagena (one PM10 sampler located at a traffic hotspot and the
PM2.5 sampler at a suburban station), during 2004 and 2005. Results
showed that in the PM10 fraction, the zinc metallurgical activity
was linked to high levels of Cd, Zn and Pb; shipyard emission
was associated with high levels of Cr and Ni; and high Ni and
V levels were associated with the secondary aerosol indicating
the contribution from oil combustion (oil-fired power station
or petrochemical facilities). In the PM2.5 size fraction, the
zinc source is defined by Zn and Pb; V, Ni and As appear with
the oil combustion emissions. in contrast to PM10, shipyard activity
is not consistently defined. Consistent sources found in both
size fractions include crustal materials and traffic emissions.
