In the present study it was evaluated the capacity of molasses for removing seven metals (Fe, Zn, Cu, Cd, Cr, Pb, and Ni) from three types of waste: galvanic sludge (pH = 7.1 ? 7.8), mineral residue from a lead metallurgical plant (pH = 5.0 ? 5.8) from Baia Mare (Romania), and tailing pond residue from Aurul - Baia Mare (pH = 2.1 ? 3.0). Several leaching tests were conducted in the laboratory in order to investigate the influence of molasses concentrations (0 %, 1%, 5%, 10%) on heavy metal leaching. It was observe...

Due to its geographical location, in the atmosphere above Romania several types of aerosol particles can be present: continental, biomass burning, and mineral dust aerosols. The vast majority of industrial facilities are located near urban areas; therefore the exposure of the human population to high concentrations of particulate matter can be significant. Although local sources are the major contributor to the air pollution in Romania, the contribution of remote sources is often significant, both aloft and near t...
