Aquatic toxicity assays/ Ecotoxicity

Daphnia sp.; Acute Immobilisation Test, OECD 202
Microtox Test, DIN EN ISO 11348-2

Aquatic and terrestrial ecotoxicology, focused on the assessment of toxic impact of chemical compounds on organisms. These studies can be of interest for the development of new products and their registration (acordding to REACH). More specific tools are:
1 - Essays developed for each product, for the computation of efective doses (EC50, NOEC, FEC, and so on), employing several aquatic organisms (unicellular algae and microinvertebrates)
2- Multiple toxicity essays (sevaral compounds acting simultaneously)
3- Acute toxicity essays (48 and 96 h) and chronic (21 days) with Daphnia sp.
4- Acute toxicity essays (96 h) with unicellular algae (Selenastrum capricornutum, Scenedesmus subspicatus, Chlorella vulgaris, Microcystis aeruginosa, y Anabaena flos-aquae)

Determination of the toxicity of aqueous samples (water or extractions from soils, sediments or solid residues) by exposure of the microorganism Vibrio Fischeri.

To study the toxicity of samples and/or compounds using established toxicity tests: effects on model animals as Daphnia magna and Danio rerio, as well as effects on the growth of freshwater microalgae and/or cyanobacteria.
