GYMNOTOX Biodetector of global toxicity
What is biodetection ?
The use of alive organisms to control in a global and continuous way the quality of an environment. Biodetectors are systems assigned to capture treatment and analysis in a continuous and automatic way of responses developed by a biological reagent.
Biological reagent: Apteronotus Albifrons
The biodetector Gymnotox exploits electrical signals naturally emitted by a fish from freshwaters in South America, called Apteronotus Albifrons. This apteronotus has the characteristic to see the frequency and the form of its signal, notable of stability in normal conditions, varied when the physicochemical quality of the surrounding area changes (arrival of a pollution wave for example). An university research of several years permitted to reveal and to verify that organic reaction of Apteronotus Albifrons, specie available in the majority of pet shops.
Principle and function of Gymnotox
Biodectector Gymnotox collects electrical signals of Apteronotus Albifrons and exploits them in order to identify any abnormal electrical behaviour. The two fishes are respectively placed in two life tubes, crossed by the water to control, thermo-regulated at 25 °C. Each individual has an electrical imprint which is proper then it is considered as its own witness when at each moment, the device compares values of its two characteristics (frequency and form) with historical data (registered in the same individual). Each abnormal electrical behaviour, necessarily due to a physicochemical variation of the water is then detected.
In the case of detection :
- The OPERATOR is immediately alerted
- Gymnotox takes a sample of water which will permit, through laboratories analysis, to identify the nature of the pollution
- A safeguard procedure of Apteronotus Albifrons is committed with an arrival of water not polluted in life tubes
FIELDS OF APPLICATIONS :
- SUPERVISION OF WATER RESOURCES
- COMPLEMENTARY EQUIPEMENT OF ALERT STATION
- WATCH ANTIPIRATE DEVICE
- PROTECTION OF DRINKING WATER TANKS
