Scientific Substantiation

The aim: Scientific substantiation necessary of PMWW application for the ecologically safe formation of the secondary ecosystems in the mining and iron ore processing areas. Materials and methods: Sanitary-chemical investigation of water samples (n=132); biological objects – plants and aquatic biota was conducted on the content of Pb, Cd, Zn, Mn, Cu, Cr, Ni, Fe (n=112); wild plants samples (n=135); sanitary-microbiological and parasitological indicators 1 – 3 years old waste water sludge (WWS) (n = 68). Results: Overnormal concentrations of salt had been found in water samples, taken from the river Inhulets (2.1 MPL), sulfates and carbonates (2.7 MPL), iron (2.1 MPL), chloride (1.7 MPL), magnesium (3.1 MPL). In wells from nearest villages water is not suitable for drinking purposes and contains total sum of salts – 4.97 MPL, sulfates and carbonates – 5.16 MPL, cadmium – 3.7 MPL, lead – 1.53 MPL. Thus, the toxic heavy metals concentrations (Pb, Cd, Zn, Mn, Cu, Cr, Ni, Fe) in the fish and amphibians did not exceed the permissible levels. Conclusions: Total pollution of the soil within six months after application of sludge correspond to the “permissible” level (Zc=1.61). Use of clearing facilities sludge aged from 1.5 years old and of longer in the amount 15 kg/m2 did not lead to increased concentration of heavy metals in the top layer of dumps.

Impact Of Mining

The topic presented in the paper refers to two significant aspects regarding the impact of mining operations on the environment and the development of an alluvial mining project in the affected area. The mine waters that drain from the Cizma mining perimeter have an acidic character with a pH of 2.5 at the exit of the gallery with a load of heavy metals in ionic and precipitated form, discharging into a mountain stream, which later reaches in the area of some communities. The perimeter is located in a protected area, which encumbers exploitation projects in these areas.

Ore Treatment

Old environmental loads are priority environmental problems in Slovakia. An old environmental load is an anthropogenic constituent in landscape which has its origin in past works (for example mining and mineral processing) but in present time it can also pose risk for the environment. One of environmental loads in Slovakia is sludge bed in Slovinky. Village Slovinky is well-known for mining activities during several centuries. From the beginning copper ore was mined there, later on iron ore which was processed in the metallurgical factory in Krompachy. The mining activity in Slovinky was stopped in 1993. Flotation slurry from ore treatment plant was deposited on the sludge bed which was operated from 1968 to 1999. More than 4.8 million cubic meters of slurry is deposited there. Locality of Slovinky is included in State Remediation Program of Environmental Loads (2010-2015). The paper summarizes the actual state of knowledge about environmental impact of mineral processing and theoretical analysis of problem of environmental impact of environmental load – sludge bed in Slovinky. Experimental part of the paper is focused on study of possibilities of elimination of heavy metals in sludge bed material with the aim of improvement of the environmental quality of surveyed locality.

Sanitary landfill facilities are essential to modern societies as repositories for municipal solid wastes. However, they always entrain a certain risk of environmental impact. For this reason monitoring is essential to their operation. In the present work, the environmental impact of such a landfill is studied. Soil samples were collected in and around the landfill and their mineralogy was studied. Top layers of stream sediments were collected to examine possible dispersion of pollutants in the environment. Chemical analyses showed enrichment in As, Cu, Zn, and Pb in the stream sediments compared to uncontaminated samples. The presence of anions such as chloride, sulphate and phosphate adsorbed on clay minerals suggest the interaction of stream sediments with run-off water from the landfill. The groundwater near the landfill site was characterised as not potable and not suitable for irrigation purposes, because some parameters such as NO3 - and Cl- were close or exceeded the permissible limits given by EE, EPA and WHO.
