- Abstract
- Direct and simultaneous determination of Al,
Ag, As, Cd, Co, Cr, Cu, Fe, Mn, Mo, Pb, Sb, U, V
and Zn in diluted (1:10 v:v) seawater from the Antarctic
Ocean and the Venice Lagoon at the ng mL-1
and pg mL-1 level has been performed by using an
inductively coupled plasma sector field mass spectrometer
(ICP-SFMS). Samples were analysed by using
a PFA microflow nebulizer coupled with a desolvation
system or a PFA microflow nebulizer coupled with a
Teflon spray chamber, respectively. Measurements
were carried out at low (LR, m/Dm=300), medium
(MR, m/Dm=3,000) and high (HR, m/Dm=7,500)
resolutions depending on the studied isotope. To avoid
contamination, sample pre-treatment was carried out
in a clean laboratory equipped with a Class 100 vertical
laminar flow hood. Concentration ranges (minimum
maximum in ng mL-1) found in the Antarctic
seawater samples (in depth profiles) were: Ag 0.0004
0.0018, As 0.691.32, Cd 0.0310.096, Co 0.0180.065,
Cr 0.180.46, Cu 0.041.58, Fe 0.131.63, Mn 0.02
0.12, Mo 5.9712.46, Pb 0.0070.074, Sb 0.0330.088,
U 0.51.9, V 0.62.5 and Zn 0.160.80. Concentration
ranges (minmax in ng mL-1) found in the Venice
Lagoon water samples (temporal profile from a benthic
chamber experiment) were: Al 0.240.61, Ag 0.007
0.031, As 1.422.27, Cd 0.0500.182, Co 0.4401.461,
Cr 0.150.34, Cu 0.812.46, Fe 0.251.66, Mn 11.6
31.7, Mo 6.5010.6, Pb 0.0470.225, Sb 0.2400.492,
U 1.73.3, V 1.32.8 and Zn 5.2021.5. The detection limits range between 0.06 pg mL-1 for Ag and U to
15 pg mL-1 for Fe. In order to check the accuracy of
the analytical procedure, measurements of the trace
elements in a certified reference material (coastal
Atlantic seawater, CASS-4-NRCC) were compared
with the certified values. In addition, the results from
the Antarctic and Venice Lagoon samples were compared
with those obtained by using different analytical
techniques. (literal)
