water has an important role in creating pollution problems in the mining regimes influencing the surrounding surface environment. the purpose of this study is to make an assessment of groundwater quality in an underground mine site in portugal with a view of determining the pollution potential of groundwater. in the corresponding surface area of this underground mine, intersections of fou...

Determining the distribution of heavy metals in groundwater is important in developing appropriate management strategies at mine sites. In this paper, the application of artificial intelligence (AI) methods to data analysis,namely artificial neural network (ANN), hybrid ANN with biogeography-based optimization (ANN-BBO), and multi-output adaptive neural fuzzy inference system (MANFIS) to estima...

Mining activities frequently leave a legacy of residues that remain in the area for long periods causing pollution surroundings. We studied on 100 year-old mine, behavior potentially toxic elements (PTEs) and their ecotoxicological impact activity diversity microorganisms. The PTEs contamination assessment allowed classification materials as highly (reference- contaminated-samples) very pollute...

Dispersion of lead (Pb) in mine wastes was simulated for reproducing Pb contamination soil Kabwe District, Zambia. Local weather data year 2019 were monitored situ and used the simulations. The plume model, weak puff no model adopted calculation dispersion under different wind conditions. results showed that from directly affected by directions speeds dry season, although it not appreciably rai...

In this paper are presented general geological data for the polymetallic Hajvalia deposit. particular, we have scientific results regarding chemical and mineralogical composition of sulfur mineralizations from The distribution main metals used during mining activity in deposit has been studied with special emphasis. From microscopic description mineral samples deposit, following compositions re...

Metals have been used by humans for thousands of years, and this has resulted in increased concentrations in the biosphere. The environment around pointsources, such as mines and smelters, are of particular concern, as metals may accumulate to high concentrations, and potentially reach levels toxic to the local flora and fauna. This thesis focuses on the effects on pied flycatcher populations o...

Heavy metals are considered as one of the important pollutants in the environment, particularly in the aquatic ecosystems. The presence of cadmium in food chain is toxic to human health. Different physical or chemical methods have been used for removing heavy metal ions in the water and wastewater treatments. The aim of this work was to assess the possibility of Cd removal from aqueous solution...
