Sažetak
For decades scientists worldwide have tried to develop continuous marine monitoring system using a variety of test organisms. Several international companies have registered patents for devices performing real time early warning response. Yet, there is no significant implementation of such solutions in marine ecosystems monitoring mostly due to inconsistent behaviour of living organisms as bio-indicators. Therefore, the goal of this research is the development of continuous 24/7 biological monitoring system sensitive to pollution of marine environment and test of its possibilities of application to the Adriatic Sea. The research design puts a focus on the apparatus set up capable of data collection of the test organisms’ behaviour. The blue mussel Mytilus galloprovincialis response to environmental stress by shell valves opening and closing. The monitoring method is a Hall sensor which allows an observation of living organisms actively responding to the environmental condition change. The dynamics of shell gaping indicates sea water quality. In a presence of potentially harmful substances mussels open and close their valves with recognisable frequency. Duration of the closeness of shells and the number of the „clicks“ mussels perform in time in comparison to the control organisms is in a relation to the pollution exposure time. The apparatus consists of wired magnetic Hall sensors attached to the mussel valves. The sensor registers each valve movement as an open or a close position. The latter position allows an electrical signal to flow to the PLC device which translates it to the useful data. Three concentrations of metal ions (Pb, Zn and Cu) dispersed in aerated sea water in vitro during 72h, 96h and 156h changed the test organisms' environmental conditions. Additionally, there is no feeding and the temperature is 16°C constantly. The blue mussels’ responses to heavy metal concentrations indicate organisms’ sensitivity and eligibility of this method as a short-term test for marine environment monitoring.
