A 3-year systematic investigation (2007–2010) of water chemistry using conventional and stable isotope tracers helped us delineate hydro-biogeochemical processes in the karstic Krka River watershed. By mineralogical and stable isotopic examination of tufa deposits and combining the results with water chemistry, we were able to evaluate the suitability of tufa …

Mercury is a very toxic element. Due to its volubility it is present everywhere in the environment at ambient temperature. High temperature processes increased levels of mercury on the global scale. Global and European action plans were established to reduce mercury emissions and remove mercury from the environment. Cement plants …

Nitrogen (N) is an essential nutrient for plant growth and one which has the greatest effect on the yield. Since effective indigenous sources are insufficient by far to support current levels of global agricultural outputs, N is intensively applied by farmers in the form of N-based fertilisers. However, excessive rates …

Selenium (Se) has been demonstrated to be an essential trace element for maintenance of animal and human health. Se is incorporated into proteins to make selenoproteins, which are important antioxidant enzymes. The antioxidant properties of selenoproteins help to prevent cellular damage caused by radicals. Radicals are natural by-products of oxygen …

Mercury (Hg) pollution has been investigated in the area of the Idrija mercury mine, Slovenia, where the second largest mercury mine in the world operated for more then 500 years. Although the production of mercury at the Idrija mercury mine stopped in 1994, centuries of mining and ore processing operations …
