The use of NPs has increased in these years. It is used
in many fields: industrial and commercial sectors. The
large use may compromise the human and the ecosystem
health, because it doesn’t know the fate/damages/
consequences of NPs in the environment. SP-ICP-MS
is a fast method and it can be used for a screening of
environmental samples, it combines high sensitivity
with analytical speed. This is a water surface study. We
collected water surface in a few rivers in the North East of
Italy. 3 liters of surface water were filtered with a vacuum
pump with membrane with 0.22 µm pore. The filter was
put into a test tube with 30 ml of water ultrapure and it was
sonicated for 20 minutes. The analysis was performed on
SP ICP MS NexION 350 D Perkin Elmer using Syngistix
software. Transport efficiency and particle calibration were
performed with standard gold nanoparticles of 30 nm, 60
nmand 90 nm. For the test, five replicates of water ultrapure
were analysed and LR was calculated. The recovery test
was made on water surface spiked and un-spiked and it
appeared to be between 94% and 97%. Considering the
high dilution of NPs in environmental complex matrix,
this study evaluated the efficiency of the concentration
via filtration for SP-ICP-MS analysis of nanoparticles of
ZnO CeO2 TiO2 Ag. The results showed that the analysis
in SP-ICP-MS combined with the filtration allowed to
lower the sensitivity of detection and characterization of
nanoparticles of two orders of magnitude.
