For each Gaseous Component
there is a specific collection cartridge
and sampling protocol. The sampling
procedures are easily carried out
by end users in the field. The sampler’s
patented radial design results in
very high sampling rates, with negligible
sensitivity to wind and air turbulence,
enabling shortterm, high resolution
measurements. The innovative cylindrical
diffusive barrier used in the Radiello
sampler (synthesized microporous polyethylene)
provides for a very consistent gas
sampling rate over extended periods
of time. |
Radiello Passive Air
Sampling System — Regulatory Status
and Recent Projects.
The overall reliability of the Radiello
sampling device has been tested by the European
Reference Laboratory for Air Pollution (ERLAP).
The results were judged “Excellent”,
since measurements carried out by six different
European laboratories showed an overall
relative uncertainty lower than that offered
by the best field instrumentation presently
available. The system is included in ISO
16200-2 for the sampling and analysis of
volatile organic compounds, and conforms
to the CEN/TC 264 WG 11 standard.

Recent International Projects.
The Radiello sampling system has been widely
used throughout Europe and the United States.
Significant recent projects include the
“ Resolution Project”, the “MACBETH
Project” (Monitoring of Atmospheric
Concentration of Benzene in European Towns
and Homes) and the “Auto Oil”,
Vehicle Pollution Monitoring Study. The
MACBETH Project is briefly described in
the following.
|
MACBETH (Monitoring
of Atmospheric Concentration of Benzene
in European Towns and Homes) is part
of the European Commission’s
ongoing “Life Program”.
Hundreds of sampling sites have been
chosen in each of the towns of Antwerp,
Athens, Copenhagen, Murcia, Padova
and Rouen. 6,205 samples were collected
equally distributed over the six towns.
The samples included 3,147 environmental
data, 1,559 personal exposure data
and 1,499 home pollution data. Due
to the innovative methodological approach,
it is possible to draw highly spaceresolved
isolevel maps of benzene concentration
on each of the monitored towns, providing
a powerful decisional tool for the
planning of traffic and road networks.
