Sava river

The Sava river basin is of great significance because of its outstanding biological and landscape diversity. It hosts a large complex of alluvial wetlands and large lowland forest complexes. The Sava is a unique example of a river where some of the floodplains are still intact, supporting both flood alleviation and biodiversity. 

Four Ramsar sites, namely Cerknisko Jezero (SLO), Lonjsko Polje (CRO), Bardaca (B H) and Obedska Bara (SER), and numerous important bird and plant areas, protected areas at the national level, and Natura 2000 sites have been designated in the Sava river basin. 

The Ramsar site and the important bird area Lonjsko Polje Nature Park (510 km2) represent mainly palustrine-riverine wetlands located within the flood-plains of the Middle Sava river basin (Central Posavina, Croatia). It represents the largest maintained inundation area of all the Danube River catchment and, at the same time, the key facility of the flood control system of the entire Sava river basin (including Bosnia and Herzegovina, and Serbia and Montenegro).

Some information on environmentally relevant reversal agents is available from aquatic invertebrates. P-gp-related dye exclusion in the mussel M. califomianus was inhibited by the moderately hydrophobic pesticides pentachlorophenol, dacthal, chlorbenside and sulfallate, but not by DDT, DDD, DDE or the PCB Arochlor 125432. Similarly, Diesel-2 oil water-extracts increased the accumulation of vincristine in the gills of M. galloprovincialis91. In the freshwater mussel Dreissena polymorpha, water from the polluted Sava River increased the accumulation of fluorescent P-gp... 

Sava river and selected streams and lakes in the Zagreb city area, undertaken in 1992, showed that all samples contained PCBs at levels of 3-25 ng 1, comparable to those measured in the Kupa river. The highest PCB concentrations were determined in the Sava river water, while the levels of OC pesticides (water samples near or at the detection limit. The principal and, in most cases, efficient purification stage of ground waters in the Zagreb city area is natural filtration through the subsurface sediment layers. Due to their favourable composition soil and sediments serve as natural sorbents for the removal of major water contaminants. 

The presence of CPs was confirmed in several surface waters in the continental part of Croatia in the Sava river along a river stretch extending up to 26 km upstream and 36 km downstream of the central Zagreb city area [17], in a number of small streams and lakes within the Zagreb city area [14], and in the Kupa river both upstream and in the area of the town of Sisak [8],... 

As in the Sava river, the highest CP concentrations in the Kupa river were measured for PCP. PCP was present in all river water samples collected nfonthly from March 1988 to April 1989 (Table 20.6) [8]. PCP concentrations in the Kupa river water was in general not dependent on the river flow rate. Unlike the Sava river, the Kupa river contained occasionally traces of 4-CP and the incidence of 2,4-DCP and 2,4,5-TCP was significantly higher. The concentrations of CPs in both the Sava and the Kupa river were far below the maximum limits of 0.1 pg 1 for 2-CP, 0.3 pg 1 for 2,4-DCP and 1 pg I fw 2,4,5-TCP,...

At the conclusion of the conflict more monitoring will be necessary, especially to monitor foodstuffs growth near large munition explosions, eg, Delnice and Ogulin (see chapter by SreboCan) and for fish in the Sava and Drava rivers and crops and cattle exposed to its waters. 

Zasavica/Sava confluence, and downstream sites of the river Zasavica in order Modran , Valjevac , Sumareva , Ravnjanska , Rajevica , Gajica . A sequential extraction procedure was applied for partitioning of metals into five fractions. The examined river sediment samples are very interesting because of their great surface area and content of highly adsorbing minerals that are adsorbing toxic heavy metals, for example lead and cadmium.
