Olivier Pourret

Olivier Pourret received his PhD in Earth Sciences in 2006 from Université de Rennes 1 (France). He is now an associate professor of geochemistry at UniLaSalle, Beauvais (France) and co-head of the research group AGHYLE (Agroecology and Hydrogeochemistry). In 2013, Olivier Pourret received his Habilitation in Earth Sciences from Université Picardie Jules Verne (France). He is a Fellow member of the Society of Economic Geologists and member of the Geochemical Society, European Association of Geochemistry, American Geophysical Union and American Chemical Society. His research interests include trace metal fractionation and particularly critical elements (rare earth elements, cobalt, vanadium) in low-temperature aqueous systems, a better understanding of trace metal cycles in natural waters, and an improved knowledge of trace metals mobility from rock to soils and vegetation in the critical zone.

New Insights On Aquifer Perturbation After CO2 Injection As Illustrated By Rare Earth Element Behavior

Rare earth element (REE, lanthanides plus yttrium) behavior in natural environments has been extensively studied. REEs are valuable as components of electronic and renewable energy technologies. The European Community lists REEs as critical raw materials. An understanding of the mobility, […]

New Insights Into The Aqueous Chemistry Of Tetravalent Cerium

The prediction of cerium aqueous speciation is relevant in many research fields. Indeed, cerium compounds are used for many industrial applications (e.g. in flat-screen TVs, low-energy light bulbs, and floodlights), which may require the control of cerium aqueous chemistry for […]

Acid Mine Drainage: A Huge Problem Around Abandoned Mines

Acid mine drainage (AMD) is an acidic mineral solution that flows out of a mine. The phenomenon in question is spontaneous and involves metal sulfides (type “M” Sx) with no economic value in mining. Indeed, during mining work (excavations and […]

Rare Earth Elements From Manganese Oxide-Rich Sediments: Some New Evidence Of Extraction And Separation

As I wrote in one of my previous articles, the industry is becoming more and more demanding of many metals. The perceived supply risk for essential raw materials used in the growth of green energy and other state-of-the-art technologies provides […]

Vanadium In Shallow Groundwaters: A Potentially Dangerous Pollutant?

Among the critical elements (Figure 1), vanadium (V) has been proposed to be a potentially dangerous pollutant, especially in the critical zone. The United States Environmental Protection Agency categorizes V in the priority list of environmental risk elements. Fixing the […]

The Mobility Of Copper And Cobalt In Metalliferous Ecosystems 

As I explained in my previous article on the environmental impact of the increasing demand for cobalt (Co), mineral resources have been exploited in the Democratic Republic of Congo (DRC) for thousands of years. Such exploitation results in abandoned metalliferous mine wastes […]

What Is The Answer To The Universe, Life, And Everything Else?

“The Answer to the Great Question… Of Life, the Universe and Everything… Is… Forty-two,” said Deep Thought, with infinite majesty and calm… “I checked it very thoroughly,” said the computer, “and that quite definitely is the answer.” — Douglas Adams, The Hitchhiker’s […]

When Rock Meets Life

It all started in 2005 during a trip to the United States, where I went to a famous conference in geochemistry (Goldschmidt Conference, Moscow, Idaho). The following weeks I crossed the Rocky Mountains and visited many national parks, including Yellowstone […]

From Coal, A New Source Of Rare Earth Elements — But Also A New Identified Risk To The Population! 

Rare earth elements (REE) have become a highly valuable commodity due to their increased use in emerging technological applications. The future exploitation of areas with high REE content will play a strategic geopolitical role around the world, as shown in […]

Does Acid Mine Drainage From Coal Mining Contaminate Fertile Soils And Crops?

In several countries like China or Vietnam, open-pit coal mining is one of the major causes of pollution (freshwater, soil, or air). Indeed, overburden and acid mine drainage from coal mining contaminate soils and produce pollution and, thus, unproductive wastelands. […]
