The Kupa River, located in the west-central part of Croatia, is a 294 km long tributary of the Sava River, belonging to the Danube watershed. An extreme barium anomaly in sediments of Kupica and Kupa rivers was discovered during 2003 by Franciskovic-Bilinski. It originates from an abundant barite mine in Homer-Lokve area, from where it penetrated to Kupica River source. From there the Ba-anomaly in sediments was followed more than 120 km downstream along both rivers. This discovery has a big potential to be used i...

Assessment of selected (trace) elements and nitrate along the 26.7 km long Radonja River (Croatia) was examined with the purpose of testing the ability for small rivers to serve as a model for identification of sources and dispersion of common environmental contaminants. The Radonja River rises and flows through specific geological region of the Petrova Gora Mt. (507 m a.s.l.). It is located in the middle part of Croatia, with the Vojni? town (~5,000 inhabit.) as the largest settlement along the whole river course...

Establishment of regular river sediment monitoring, in addition to water monitoring, is very important, as geochemical data of sediments are very significant for environmental impact assessment. First scientific investigations of sediments in Croatia started in the Krka River estuary in 1989, while first systematic research of a river basin in Croatia was performed in the Kupa River drainage basin in 2005. In 2008, Croatian water authorities (Hrvatske Vode) started a preliminary sediment monitoring program. Since ...

A mercury-cell chlor-alkali plant operated 50 years in KaпїЅtela Bay (situated in the middle of eastern Adriatic coast) near the town of Split. Even after 28 years the abundant cell house is still a hazardous source of the total gaseous mercury. Measured concentrations in the air (2.1 пїЅ 9.6 ?g m-3) could possibly present Hg-pollution of 9 km distant source of Jadro River. This source is used as a drinking water supply for the town of Split. The aim of the work was to find how far mercury is transported. Total me...
