It is well known that atmospheric aerosols have both a direct and an indirect impact on the Earth's systems and have natural or anthropogenic origins. In this paper we present the results of the 2022 spring-time lidar measurements conducted within the European Aerosol Research Lidar Network (EARLINET) using a multi-wavelength Raman and depolarization LIDAR system operated in Cluj-Napoca, Romania. The Cluj-Napoca lidar system (CLOP) emission is based on a Nd-YAG laser Continuum INLITE II-30, which has a repetition ...

In this paper we present a case study regarding a desert dust intrusion over Central and Eastern Europe in 5th of April 2021, observed using a multi-wavelength Raman and depolarization LIDAR system operated in Cluj-Napoca, Romania. This type of system meets the requirements of the European Aerosol Research Lidar Network – EARLINET and is suitable to provide reliable data on optical parameters for aerosol characterization. While mineral aerosols are the second largest source of aerosol and are the subject of long r...

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 пїЅ 7.8), mineral residue from a lead metallurgical plant (pH = 5.0 пїЅ 5.8) from Baia Mare (Romania), and tailing pond residue from Aurul - Baia Mare (pH = 2.1 пїЅ 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 o...

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...
