1. Batch Sorption Studies of Aqueous Cadmium and Lead from Contaminated Water onto Selected Biosorbents
Abstract : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies.

2. On the chemical state and mobility of lead and other trace elements at the biogeosphere/technosphere interface
Abstract : Most inorganic contamination has occurred at the interface between the technosphere and the biogeosphere, even though atmospheric emissions have affected the entire globe. Several human activities now pose a substantial threat towards human health and the ecosystems. READ MORE

3. Ancient DNA as a Means to Investigate the European Neolithic
Abstract : The transition from a hunter-gatherer lifestyle to a farming lifestyle, i.e. the Neolithisation, is arguably the most important event in human prehistory. While the geography and dating of the Neolithisation is well known, the process is still under debate, especially if it occurred through diffusion of ideas or with migrating farmers. READ MORE

5. Effects of heavy metal contamination on carbon and nitrogen cycling : An ecological approach to assess risks to soil functions
Abstract : Soil contamination with heavy metals may disrupt soil microorganisms with important roles in carbon (C) and nitrogen (N) cycling. However, there is a lack of understanding on how microorganisms are affected in soil, which may lead to a mismatch when assessing risks of contaminants to field soils. READ MORE
