On-line biomonitoring of the degree of pollution in water is carried out by a unit capable of continuous detection of swimming ability of fish in a water current. The unit has a water inlet port (1), a horizontally constructed vessel (2) with an outlet (6) to ensure uninterrupted water circulation at atmospheric pressure. The vessel (2) has a built in electromechanical detector (4) which is forced to rotate by the water current. This rotation generates impulses that are transmitted as signals to an associated evaluation computer (5). Changes in the degree of pollution of water are detected by changes in the ability of fish to swim. |
