Uranium (U), present in the tetravalent form (relatively insoluble as U(IV)) in igneous rocks, undergoes oxidation and mobilization as part of weathering. As a result, oxidized uranium (hexavalent, U(VI)) is present in surface waters, particularly in areas with an underlying granitic bedrock. In anoxic soils and sediments, uranium can accumula..
The impact of volcanism on Earth's atmosphere: from present-day volcanic 'pollution' to geological mass extinction events
Volcanoes are spectacular natural phenomena. Earth has experienced volcanism since its beginnings and observing a volcanic eruption is a truly primeval experience. Volcanoes have shaped our planet and have been key in creating and maintaining its habitability. However, they can also be deadly natural hazards and are implicated in some of the g..
Since 30 years the Mainz Vertical Wind Tunnel facility is operational for experiments on cloud microphysics and chemistry with emphasis on larger hydrometeors. After the extending the facility for performing experiments down to -30 C processes relevant for mixed phase clouds can be simulated. Recently such experiments to characterize the coll..
Tailings are wastes comprising mixtures of crushed rock and processing fluids from mills, washeries, or concentrators that remain after the extraction of economic metals, minerals, mineral duels or coal from the mined resource. They contain potentially toxic metals and metalloids and can be very reactive, generating acidity or alkalinity and a..
In April 1986, Reactor 4 of the Chernobyl nuclear power plant underwent a catastrophic failure. This nuclear incident resulted in 31 direct deaths and caused a radioactive plume to spread across much of Europe and the former USSR. During the meltdown of the reactor core, temperatures reached >1600°C from the uncontrolled decay heat of the fis..
