Drava river

In the upper stream of the Meza River, including significant tributaries (e.g. Topla, Helenski potok, Musenik, Jazbinski potok, Juncarjev potok), the stream sediment samples were collected approximately 1 km apart. From Mezica to the Drava River the sampling distance was increased to 10 km. Additionally, two samples of the Drava River sediments were taken before and after its confluence with the Meza River (Fig. 1). 

Relatively high contents of As in Drava River samples (ME-23 and ME-24) are a consequence of the Drava River catchment area characteristics. 

Seven stream sediment samples of Meza River with its tributaries (Topla, Helenski potok, Musenik, Jazbinski potok, Juncarjev potok) (ME-1, ME-5, ME-14, ME-17, ME-18, ME-20) and Drava River (ME-24), were analyzed using SEM/EDS. They contained Pb, Zn, Cr, Ni, Mn, Mo, Cd, Ti, V, W, Zr, Ce, Sb, Cu, Y, Sr, Ba, and Ag, found in different heavy metalbearing phases. 

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.
