Did you know that each of these tracers could follow its own marine story, quite decoupled from the others? This is what is shown and discussed by Zheng and co-workers […]

Lead
Testament of the efficiency of environmental policies
Human activities, such as the combustion of leaded petrol, emissions from non-ferrous metal smelting, coal combustion and waste incineration constitute major environmental lead (Pb) sources during the past century. This […]

Decreasing of the industrial lead contamination in the Amundsen Sea area
Since the phasing-out of leaded automobile gasoline, the imprint of industrial lead is decreasing everywhere. Antarctica snow and ice are no exception to this general rule, as shown by measurements of […]

Lead isotopes tracks leakage of Indian Ocean seawater into the Atlantic Ocean
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 to measure lead isotopes in the ocean with an outstanding precision
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 […]

Analyzing rapidly, precisely and semi-automatically lead isotopes on variable volumes of seawater (up to 1000 ml)
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 […]
