“…In the early 2000s, exploitation began to decline, and the exploitation was quickly shut down, leaving behind millions of tons of ore residues, which were used in the production process. The studied area represents a major pollution source, with thin particles of hazardous dust being carried in the atmosphere by the wind and transported to the neighboring shore in Serbia (Burlacu et al 2017).…”

The aim of this study is the assessment of rainwater composition, regarding the various sources of major ions and heavy metals, taking into account the characteristic atmospheric circulations and the main air mass transport routes. Rainwater samples were analyzed for pH, electrical conductivity, major ions, and heavy metals. At all sampling sites, the most abundant anions were SO 4 2ā nd Clˉ, while the dominant cations were Ca 2+ and Mg 2+. Regarding heavy metals, the dominance of Pb and Cd was found. The contribution of soil dust from the mining activities and the dissolution of CaCO 3 , MgCO 3 , and CaSO 4 •2H 2 O in the rainwater explains the high concentrations of Ca 2+ , Mg 2+ , and SO 4 2−. The overall precipitation contamination with heavy metals at the three sampling sites was assessed by the degree of contamination, showing that Pb and Cd presents the highest risks of all heavy metals. The values of toxicity potential suggested an elevated risk for human health in case of rainwater ingestion, especially in rural areas. Spearman correlation and PCA indicated that the chemical characteristic of the rainwater is primarily controlled by sources such as agricultural activities, mixed and crustal sources, traffic, and other anthropogenic, industrial influences, mining activities, smelting operations, coal combustion, and metal production.

“…According to previous studies, the highest dust concentrations have been measured in the dump area, gradually decreasing with the distance, depending on the wind speed and direction [6]. Drought periods are the greatest hazards, as low air humidity in strong wind conditions favours the resuspension of fugitive dust and the dispersal of pollutants from tailings ponds [7].…”

This paper concerns to the air and soil pollution in the area of tailings ponds in Moldova Nouă, situated on Danube bank, near the Romania-Serbia border. The tailings ponds resulted from mining operations since the previous century, represent now a source of historical pollution in the area, especially on air quality, through dispersal of tailings dust on large surfaces. Depending on weather conditions, especially in case of drought periods, the wind of various intensities raises the dust and disperses it, affecting land surfaces: urban, tourist, agricultural, protected areas of community interest, like RAMSAR Iron Gates Natural Park-Divici-Pojejena Wetland. The dispersion has a direct effect on human health because of its chemical composition, which may contain SiO2 and heavy metals like Cu, Pb, Cd, Ni, etc. Results were obtained following several field measurements of dust particles concentrations at various critical points, in corroboration with laboratory analyses of their content. For the study of the pollutants dispersion, the Breeze AERMOD model was used for obtaining cross-border pollution maps, respectively of the historical pollution by the accumulation of heavy metals in the soil from the immediate vicinity of the analysed area.
