Lead
About the decoupled fates of aluminium, manganese, cobalt and lead in the North Pacific Ocean
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 […]

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 […]
