Dr. Nikolai Pedentchouk from University of East Anglia (UK) will give a short course on Stable Isotopes in Earth Sciences on April 18 and 20, 2017. Lectures will be supplemented with practical sessions in our isotope lab. Program will include fundamentals of light isotopes and systematics of C, O and H isotopes (PDF of program can be downloaded here). For reservation, please contact Prof. Martin Mihaljevič (mihal@natur.cuni.cz)

We studied how thallium isotopes can be used for tracing anthropogenic pollution in soils contaminated by emissions from coal-fired power plants. These results are the first published isotope data generated by our brand new MC-ICP-MS lab.

(2016): Isotopic Tracing of Thallium Contamination in Soils Affected by Emissions from Coal-Fired Power Plants. Environmental Science and Technology 50, 9864-9871. DOI

In the footsteps of previous research on zýkaite (Majzlan J., Amoako F.Y., Kindlová H., Drahota P. (2015): Thermodynamic properties of zýkaite, a ferric sulfoarsenate. Applied Geochemistry 61, 294-301, DOI) we published in Hydrometallurgy new thermodynamic data for FeAsO4·0.75H2O: Majzlan J., Dachs E., Benisek A., Drahota P. (2016): Thermodynamic properties of FeAsO4·0.75H2O - a more favorable disposable product of low As solubility. Hydrometallurgy 164, 136-140 (DOI).

Mobility of metal(loid)s in soils is strongly affected by their binding to solids. We studied smelter- and mining-derived particulates with high levels of metals and metalloids (As, Sb) and their stability in soils from dry semi-arid and wet subtropical areas in Africa. Ettler V., Johan Z., Kříbek B., Veselovský F., Mihaljevič M., Vaněk A., Penížek V., Majer V., Sracek O., Mapani B., Kamona F., Nyambe I. (2016): Composition and fate of mine- and smelter-derived particles in soils of humid subtropical and hot semi-arid areas. Science of the Total Environment 563-564, 329-339. DOI
