- New work package 3 report on water sample ring-testing (8 October 2010)
The COHIBA project aims at joint evaluation of effluents’ ecotoxicity for the whole region, based on the Whole Effluent Assessment approach. It will produce innovative toxicity-based discharge limits to effluents discharged into the Baltic Sea.
At the moment most of the restrictions that limit discharges and emissions are based on concentrations of chemicals. WEA approach aims to determine whether effluents discharged are harmful to aquatic organisms.
In order to have comparable and reliable results for evaluation of sources of target substances it is also important to harmonise the assessment methods being applied for this purpose within the Baltic Sea region.
COHIBA will carry out case studies in each coastal country, where municipal and industrial waste waters, landfill effluents and storm waters of selected sites will be screened for one year to identify their ecotoxicity and hence presence of hazardous substances in waste streams. It will further allow tracing sources of identified toxic discharges.
Work package 3: Innovative approaches to chemical controls of hazardous substances. Led by the Finnish Environment Institute.
