Ecological risk assessment of environmental pollutants in freshwater ecosystems

  Research Description

Screening-level risk assessment of pollutants (SLRA), with special reference to heavy metals, polycyclic aromatic hydrocarbons and polychlorinated biphenyls. Proper site models are used to identify the stressor sources, pathways and fate of stressors of potential concern. The distribution and temporal variation of contaminants is assessed through measurements on chemical concentrations in biological material (selected biological indicator organisms).

Toxic effect assessment of pollutants: comprising hazard identification, dose-response assessment and exposure assessment. For this purpose, laboratory tests were elaborated to study primarily the effects or chronic no-observed effects concentrations (EC50 or NOEC) of compounds. The fate of pollutants is assessed through the level of disturbances evoked in the valve movement, pumping behavior and the filtration rate of bivalves, and through studies focused on the determination of the bioavailability and the bioaccumulation dynamics of contaminants in bivalves.
