Analysis and identification of pesticides and their transformation products in groundwater by High Resolution Mass Spectrometry
Abstract : Nowadays it is increasingly important for public policy to know what compounds are present in
groundwater, which of them must be monitored and their
fate
.
Thus,
specific analytical
methodology
is required
to identify these micropollutants, including emer
ging substances or
transformation products
(TPs)
potentially present at low concentrations.
To improve
limit of
detection
,
POCIS (Polar Organic Chemical Integrative Sampler) were used as passive samplers
for the pre
-
concentration of
polar
compounds.
High Res
olution Mass Spectrometry
(HRMS)
offer
ing
the possibility of detecting a large number of contaminants without pre
-
selection of analytes due to its accurate
-
mass full
-
spectrum acquisition
was also applied
.
The
combination of these two techniques
carried out o
n
s
everal groundwater sampled
monthly
confirms
the advantage of
i)
improvement of
organic chemical screening
with POCIS
and ii)
identification of non
-
targeted organic compounds with
HRMS technique.
Several
p
esticides and
some of
their transformation products were
detected for the first time in these
sites
.
