Pharmaceuticals and drugs of abuse are emergent pollutants which, together
with its metabolites and TPs, are subject of concern, and affect water quality
and aquatic life. These enter into the water body after consumption and
excretion by humans and animals. In addition to these emerging
contaminants, pesticides are of concern because of their wide use in
agriculture. Many of these contaminants and their metabolites are not
removed after conventional treatments in wastewater treatment plants
(WWTP), which have to apply additional treatments (e.g. advanced
oxidation) to ensure that the treated water is of sufficient quality for its use.
In this work, we used MS QTOF coupled to UHPLC for screening various
target compounds in different types of water samples, including influent and
effluent wastewater, and surface water. We have found 17 pharmaceutical
compounds of different types (e.g. telmisartan, 2 drugs of abuse (e.g.
cocaine), 3 herbicides (e.g. atrazine), and one TPs in the water samples:two
from Colombia, one from Athens and one effluent wastewater from a WWTP
Sample treatment was not a part of this work, which was focussed only on
data treatment in order to find these compounds in the spectrum manually,
through databases of exact mass spectra online and using the instrument
software. Getting 6 negative and 17 tentatively detected or identified by MS
QTOF, since reference standards were not available. [-]
