Oil and herbicide pollution in the Black Sea : detection and biological impact


Foreseen Results

The data collected on the pollution in the monitored areas will be correlated with the population distribution and physiological state of benthic/interstitial organisms that represent in this project the response of the biota to pollution induced stress. The biological impact will be studied largely as a cooperative Ukrainian : Israeli effort.
The proposed research is focused on the North and North-West sectors of the Black Sea and on the deltas of the three major Black Sea tributaries : Danube, Dnieper, Dniester. 150 sampling stations are planned. Two types of pollutants are selected for monitoring : oils representing industry/transportation of produced pollutants and herbicides representing pollutants originating from the agricultural sector. Potential of total pollutants contained in the water to generate biological damage will be assessed in the laboratory by unspecific, highly sensitive algal bioassay and in the Sea by monitoring response of benthic organisms.

It is proposed to develop novel low-cost techniques for detection of oil and herbicide pollution. The feasibility of the novel techniques will be assessed in the laboratory and subsequently in the field conditions by comparing them with conventional analytical methods. The techniques will be developed as a cooperative effort of Czech and French research teams and of a small Czech business. Testing of the novel techniques will on the cooperation with Ukrainian and Israeli teams. Conventional analytical methods will be used by the Ukrainian proposers to provide standardized information about composition and spatial distribution of the pollutants.

In parallel to the highly specific conventional and novel analytical methods, unspecific bioassays will be used to estimate the biological impact of the pollutants. The bioassay is based on the exposure of highly sensitive algal cultures to the samples of polluted water collected from the monitored areas. The response of the algae will be calibrated in the laboratory conditions by exposure to known concentrations of representative pollutant components. The bioassay will be performed by the Czech team with assistance of Ukrainian and Israeli teams.
