Christoph Noller - Ecologist and Soil Scientist. He is a Ph.D. student at the University of Natural Resources and Life Sciences (BOKU), Vienna. Christoph has worked a lot on contaminated soils with heavy metals such as arsenic (As), cadmium (Cd), chromium (Cr), mercury (Hg), lead (Pb), copper (Cu), zinc (Zn), etc. 


Description of the episode: 

In this episode, we discuss heavy metals, their influences on the human body, isotopes, soil microorganisms, and the ways of recovering contaminated soils, sources, etc. Christoph also mentions diseases such as Japanese diseases "itai-Itai", Minamata, cancer, etc.
