In this study, a scenario analysis of risk associated with regular excursions to the Suva Planina Mountain, Serbia, for adults and children over a period of five years is performed because of the high concentrations of certain heavy metals in the soil. Additionally, the source of contamination was evaluated by identifying potential anthropogenic in...

In this study, we will determine the levels of per- and polyfluoroalkyl substances (PFAS) in water, sediment, two seston fractions and fish tissue from a water reservoir used for production of potable water. Bioaccumulation and biomagnification factors (BAFs, BMFs) will be calculated across the aquatic food web, and the results on PFAS concentratio...

Per– and polyfluoroalkyl substances (PFAS) are synthetic organofluorine chemical compounds that are broadly used in amongst others aqueous firefighting foam, cosmetics, textiles, carpets, coatings, plastics, and ski wax. Their chemical properties make them persistent organic pollutants that are potential bioaccumulative and toxic. Most studies on P...

Methylmercury (MeHg) is the most important and the most abundant organic Hg pollutant in the aquatic ecosystem that can affect human health through biomagnification. It is the most toxic organic Hg form, which occurs naturally and by human-induced contamination in water and is further biomagnified in the aquatic food web. MeHg is the only Hg form t...

Methylmercury (MeHg) is a potent neurotoxin commonly found in aquatic environments and primarily formed by microbial methylation of inorganic divalent mercury (Hg(II)) under anoxic conditions. Recent evidence, however, points to the production of MeHg also in oxic pelagic waters, but the magnitude and the drivers for this process remain unclear. He...

Cellular uptake of dissolved methylmercury (MeHg) by phytoplankton is the most important point of entry for MeHg into aquatic food webs. However, the process is not fully understood. In this study we investigate the influence of chemical speciation on rate constants for MeHg accumulation by the freshwater green microalga Selenastrum capricornutum....

Oxygen depleted areas are spreading in coastal and offshore waters worldwide but the implication for production and bioaccumulation of neurotoxic methylmercury (MeHg) is uncertain. We combined observations from six cruises in the Baltic Sea with speciation modeling and incubation experiments to gain insights into mercury (Hg) dynamics in oxygen dep...

Levels of neurotoxic methylmercury (MeHg) in phytoplankton are strongly associated with water MeHg concentrations. Because uptake by phytoplankton is the first and largest step of bioaccumulation in aquatic food webs many studies have investigated factors driving seasonal changes in water MeHg concentrations. Organic matter (OM) is widely accepted...
