Staro olovo, novi izazovi: postoji li bezbedan nivo izloženosti? [PDF]

, 2022
Lead (Pb) is one of the most important toxic metals without known physiological role. Recent data indicate that any exposure, even low, can be harmful. Therefore, safe blood lead levels, as well as tolerating daily intake, have not been identified.

Application of seismic refraction methods for rock mass characterization at the lead mine tailings site in Olovo Mine

Geology, Geophysics and Environment
In this study, the application of seismic refraction for the characterization of the rock mass at the lead mine tailings facility in Olovo is presented, with the aim of identifying lithostratigraphic horizons, structural discontinuities, and zones of reduced mechanical resistance that may affect tailings stability.
