This work further contains the role that reversible scavenging may play in the cycling of lead in the ocean, an ever-evolving global experiment where lead contamination can be tracked in real-time.
This study reveals that the mean lead concentrations in the surface waters of the western South Atlantic Ocean decreased by 34 % between the 1990s and 2011.
Zheng and co-authors present the full-depth distributions of aluminum, lead, manganese and copper in the western South Pacific.
Using helium and neon as tracers for subglacial meltwater, Krisch and colleagues found that subglacial discharge is a source of dissolved lead.
Mellett and Buck present the concentrations of bioactive trace metals (Fe, Cu, Mn, Zn, Co, Ni, Cd, and Pb), Fe-and Cu-binding organic ligands, and electroactive Fe-binding humic substances in the eastern Gulf of Mexico.
Did you know that each of these tracers could follow its own marine story, quite decoupled from the others?
Bridgestock and his co-workers reveal for the first time that natural lead can be detected again in the surface water of the North Atlantic.
Nature Communications (September 2016) Bridgestock, L., van de Flierdt, T., Rehkämper, M., Paul, M., Middag, R., Milne, A., Lohan, M.C., Baker, A.R., Chance, R.,, Khondoker, R., Strekopytov, S., Humphreys-Williams, E., […]
Since the phasing-out of leaded automobile gasoline, the imprint of industrial lead is decreasing everywhere.
Stable lead isotopes have been measured by Maxence Paul and co-workers along 40°S during the first and second legs of the UK GEOTRACES cruise (GA10) in the Atlantic Ocean. They […]
A new method for the determination of seawater lead (Pb) isotope compositions and concentrations was developed, which combines and optimizes previously published protocols for the separation and isotopic analysis of […]
Zurbrick and co-authors present a relatively fast (2.5–6.5 hours), semi-automated system to extract lead (Pb) from seawater, with few chemicals yielding low blanks. They also demonstrate that subsequent Pb isotopic […]
