ToxMate : A ViewPoint innovation
ToxMate, developed by ViewPoint, is a station made to continuously detect the impact of micropollutants in the water of urban and industrial treatment plants, or drinking stations. Tested and proven in WWTPs, its ease of use and autonomy make ToxMate an optimal solution for real-time water quality monitoring
a health and environmental issue
Although micropollutants are invisible, it has been proven that they can have consequences for the environment, particularly biodiversity, as well as for human health.
Cosmetics, detergents, solvents, medicines... all these products used in daily life, at home or workplace, contain a large number of chemical substances, both synthetic and natural. Their production, and above all their use, are the source of pollutants found in water: these are known as micropollutants.
Present in very small quantities, some substances are nevertheless qualified as endocrine disruptors and are considered responsible for the disappearance of an aquatic specie every ten years.
Their very high number (more than 200,000 molecules), as well as their presence in infinitesimal quantities in water, makes their detection complex.
Les analyses physico-chimiques montrent leurs limites pour identifier leur présence : prélèvements ponctuels, délais d’analyses longs, limitation du nombre de molécules ciblées, coûts élevés…
Biomonitoring appears to be the best way to provide a rapid, reliable, global and continuous response to the detection of undesirable effects linked to the presence of micropollutants.
ToxMate, a multi-species water quality biomonitoring station
ToxMate mesure l’impact de la présence de polluants chimiques sur le vivant. A la différence d’outils type truitomètres, utilisant des truites ou des vairons, les trois espèces d’invertébrés aquatiques présentes dans la station (gammares, radix et sangsues) réagissent à une grande variété de matières toxiques et constituent des bio-indicateurs fiables et performants du niveau de pollution de l’eau. Les tests réalisés sur site ont ainsi démontré la sensibilité de ToxMate aux effets cocktails et recombinaisons, là où les capteurs physico-chimiques ne ciblent qu’une faible partie des molécules présentes dans l’eau.

Continuous real-time monitoring
A continuous flow of water, previously treated by the sewage treatment plant, is diverted to feed a ToxMate conditioning module, before coming into contact with the biological organisms. Monitoring is carried out in real time, 24 hours a day.
Alerts are triggered when reactions of the organisms to a toxic effect of the water are detected. These are linked to the findings of micropollutants, drugs or a cocktail effect of different chemicals. ToxMate alerts are instantaneous and considered to be the most effective in the biomonitoring station market, enabling reactive management of peaks in toxicity.
Simplicity and reliability
ToxMate comes with an easy-to-use online interface that generates alerts when setup predefined toxicity thresholds are exceeded. The user does not have to intervene or manipulate the equipment. No special skills are required. Installation and maintenance are performed entirely by ViewPoint.

Implanted on site, ToxMate continuously analyses, by video-tracking, the individual behaviour of 3 species of invertebrates. The collected data is then processed and analysed. An alert is triggered if pollution is detected.

How does it work?
A review of ToxMate by Viewpoint's CEO Didier Neuzeret, and INRAE ecotoxicology research fellow Arnaud Chaumot.
ToxMate is developed in partnership with INRAE (National Institute for Research in Agronomy, Food and Environment) Lyon, with the support of the AERMC (Rhone, Mediteranean and Corsica Water Agency), the European Union and the Rhône-Alpes Region.
