EUROFINS Network
EUROFINS Hydrobiologie France
▪ Various aquatic ecosystems
Running water : torrents, rivers, streams, …
Stagnant water : lakes, canals, gravel pits…
Marine waters
Brackish waters : lagoons, ponds, …
▪ Different biological and physicochemical compartments
Microalgae, aquatic plants, plankton, macroinvertebrates, fishes,
water and sediments sampling, …
WHAT IS HYDROBIOLOGY?
Science which studies on aquatic biological communities (flora and fauna)
-Impact studies and monitoring of
ecological state (WFD)
Team of european specialists
Eurofins: European team for widespread capabilities !

Ecotoxicity tests on freshwater
Surface on the water
- Water lens (Lemna minor)
Water column
- Daphnia (Daphnia magna)
- Freshwater algal (Raphidocelis
Subcapitata)
- Ceriodaphnies (Ceriodaphnia dubia)
- Rotifers (Brachionus calicyflorus)
Sediment
- Chironomes (Chironomus riparius)
- Ostracods (Heterocypris incongruens)
Ecotoxicity tests on marine water
Marine copepod (Arcatia tonsa)
Amphipod (Corophium arenarium)
Crustaceans (Artemia salina)
Bivalves (Crassostrea gigas)
Echinoides (Paracentrotus lividus)
Bacteria (Vibrio fischeri)
Internal method
«Coral cuttings toxicity test (Seriatopora hystrix)»
Why use this Organization?
- Observation of coral bleaching in the oceans
- Breeding sites for many species
- Very important for marine ecosystems
▪ Coral cuttings brought into contact in each concentration of the sample
▪ Duration of the test: 96h (renewal of the medium at 48h)
▪ Biological descriptors: NOEC and LOEC
→ Observation of whitening and retraction of polyps
Waste and sediment management
HP 14 Criterion
▪ INDIRECT Approach
▪ DIRECT Approach
Analyzes realized on the ELUATE from the sampleleaching (aquatic ecotoxicity)ACUTE TOXICITY and CHRONIC TOXICITY
Acute toxicity analyzes realized on the RAW SAMPLE (Ground ecotoxicity)
The positive answer of a single test is enough to classify the waste or the sediment as ecotoxic for the environment of the basis of thresholds
established in the regulation.
