1. Mechanisms behind pH changes by plant roots and shoots caused by elevated concentration of toxic elements
Abstract : Toxic elements are present in polluted water from mines, industrial outlets, storm water etc. Wetland plants take up toxic elements and increase the pH of the medium. In this thesis was investigated how the shoots of submerged plants and roots of emergent plants affected the pH of the surrounding water in the presence of free toxic ions. READ MORE

2. Adaptation and Protein Quality Control Under Metalloid Stress
Abstract : Toxic metals and metalloids are emerging as major environmental pollutants, having ecological consequences as well as being linked to a broad range of degenerative conditions in animals, plants and humans. While the toxicity of several metalloids is well established, the underlying molecular mechanisms are often not clear. READ MORE

3. Water treatment using cryogel-based adsorbents - Targeting environmental pollutants at low concentrations
Abstract : The lack of safe, clean water is strongly linked to poverty, underdevelopment and poor health. Water is needed not only to sustain life, but to produce food and in industrial processes. Anthropogenic pollution and natural events can jeopardize access to safe water. READ MORE

5. Suitability of industrial residues for preventing acid rock drainage generation from waste rock
Abstract : One of the main and most challenging environmental problems related to mining is the generation of acid rock drainage (ARD), a leachate characterized by low pH and elevated concentrations of sulfate, metals, and metalloids formed when sulfide-bearing minerals are subjected to oxygen and water. During the operation of a mine, waste rock is often deposited in heaps and usually left under ambient conditions, enabling sulfides to oxidize. READ MORE
