Organochlorines from the Sava River (Croatia), levels in fish and SPMD uptake

Monitoring of aquatic ecosystem pollution represents one of the major activities involved in measures aimed at environment protection. A lot of data on the ecological character of the Sava river basin are still lacking. One of the goals of FP6 EU project SARIB is collection and systematization of these data. This short paper came out as a result of this project. European chub (Leusiscus cephalus) was used as monitoring specie. Levels of polychlorinated biphenyls (PCBs)and organochlorine insecticides (DDT) are determined in tissues samples, as well as in a semi-permeable membrane devices (SPMD) deployed at different locations downstream the Sava River. Levels of DDT are much lower in comparison with levels of PCBs in all (muscle, liver and SPMD) samples. Comparison with the available data about PCB levels in muscle tissue of chubs from European rivers leads to conclusion that the chubs from Sava River are moderately polluted with PCBs. Unfortunately data about levels of POPs in liver of European fishes are still sparse (none about E. chubs). For this reason determination of the levels of PCBs and DDT in the liver of the chubs from the Sava River is especially valuable.
