Mercury in aquatic sediments and soils from Croatia

Mercury is one of the most toxic and hazardous pollutant which occurs in the environment in different chemical forms, from which methylmercury is the most dangerous. Recently it was recognized that long-term anthropogenic inputs of mercury into environment resulted in the global mercury pollution and it was concluded that the action should be taken to quantify the pollution sources and reduce human-generated releases of mercury. In this paper new data on mercury levels in aquatic sediments from about 15 Croatian rivers, lakes and estuaries are presented. Also data on mercury concentrations in soils from 8 different regions of Croatia are given. Distribution of mercury species is discussed in more details in Sava river, Krka estuary and the Kaštela bay on the eastern Adriatic coast. Results demonstrated that sediments and soils from Croatia are generally not contaminated by mercury, except for some rivers and coastal locations under direct anthropogenic influence.
