1. Spatial variability of geogenic contaminants in drinking water sources : Insights into hydrogeological controls, geospatial data for safe water supply and groundwater resource management
Abstract : The presence of geogenic contaminants in drinking water is a major health concern in many parts of the world. The interaction of groundwater with different rock types and sediments in the natural geochemical environment play an important role in controlling their mobility. READ MORE

2. The exploration and evolution of the avian genomic dark matter
Abstract : The development and improvement of genome sequencing technologies in the last decade revolutionised the entire field of biology with genome assemblies of virtually any organism. Despite this tremendous progress, complex genomic regions are systematically missing from genome assemblies and form the so-called "genomic dark matter". READ MORE

3. Multielement Urban Geochemistry : Exporing the Expected, the Unexpected and the Unknown
Abstract : Urban areas are hot-spots for the human use of most elements. These elements are the building blocks of our various goods and chemicals and are used both purposely and in a more unaware fashion. There are many ways in which the elements get dispersed from the human use. Commonly acknowledged and evident processes of dispersion are point sources (e. READ MORE

4. Influence of soil amendments and soil properties on macro– and micronutrient availability to microorganisms and plants
Abstract : Utilising by-products from industrial and domestic activities and from bioenergy production is one of the new ways of recovering and re-using nutrient resources in agriculture. However, these by-products can potentially add toxic elements or alter soil properties in ways that harm the soil and related environments. READ MORE

5. Comparative study on different industrial oxidic by-products as neutralising agent in bioleaching
Abstract : A comparative study on bioleaching of a pyrite concentrate using ten different industrial oxidic by-products as neutralising agent has been performed with a commercial grade slaked lime chemical serving as reference material. The acid produced during oxidation of pyrite was neutralised by regular additions of neutralising agent whenever needed to maintain a pH of 1. READ MORE
