Hormesis and Low Toxic Effects of Three Lanthanides in Microfungi Isolated from Rare Earth Mining Waste in Northwestern Russia
The low-dose toxicity of chloride and nitrate salts of three lanthanides (La, Ce and Nd) was tested on six microfungal species. Five of them ( Geomyces vinaceus , Aspergillus niveoglaucus , Pseudogymnoascus pannorum , Penicillium simplicissimum and Umbelopsis isabellina ) were isolated from the lopa...
