Areas contaminated with radionuclides are near the places of mining and processing of U ores. The most contaminated areas in the Czech Republic are located near Stráž pod Ralskem (chemical leaching), Rožná, and Mydlovary (U processing plants). Radioactive wastes are stored in rock dumps and piles. High concentrations of radionuclides appear also in water. In the past, contaminated soil or water was processed outside the area. These used methods were very expensive and destructive for the soil and environment. At present, the remediation tries to use the methods that preserves the functions and properties of the soil. The in situ methods offer decontamination techniques without removing contaminated soil. The present review deals with domestic U mining areas and possible methods of remediation of contaminated localities.

Fire is a common cause of damage to people and property. The fires also cause a wide variety of acute and chronic pollution due to acid gases and persistent organic chemicals. Flame retardants are highly required chemicals that improve thermal resistance of materials. Main types of fire retardants used in polymers are phosphines, phosphonates, phosphates, silanes, siloxanes, boric acid, borates, carboranes, melamine derivatives, Al and Mg hydroxides as well as nanomaterials. Generally used halogenated flame retardants are characterized by high efficiency but, due to their toxicity and bioaccumulation, are of limited use. Currently are preferred combinations of N flame retardants and P compound. Nanomaterials seem prospective in future. © Petr Zámostný.
