Noack Laboratorien offers a broad range of aquatic ecotoxicity tests with fresh water, sea water and sediment organisms according to OECD, EU, ISO and EPA guidelines. Solubility, instability and unknown composition of a test substance can be challenging issues with regard to aquatic testing. We are experts in dealing with difficult substances and finding a solution for the optimal test design. Study designs can be adjusted with regard to special requirements.
Our range of algal species includes standard fresh water green algae like Pseudokirchneriella subcapitata and Desmodesmus subspicatus but also more rare species like Navicula pelliculosa, Anabaena flos-aquae, Synechococcus leopoliensis, Chlorella, Ankistrodesmus, Chlamydomonas and Dyctiosphaerium. The sea water algae Skeletonema costatum and Phaeodactylum tricornutum are also tested on a regular basis.
Our fresh water test portfolio includes aquatic tests on Daphnia magna, Hyalella azteca, diverse Lemna species, Myriophyllum spicatum and bacteria (from activated sludge, Aliivibrio fischeri (“Vibrio fischeri”) and others). A variety of acute, early life stage and life cycle tests on different fresh water and sea water fish species is available. Bioaccumulation studies in fish can also be performed, please see section Environmental Fate for details. We offer sea water tests on Crassotrea gigas, Acartia tonsa, Tisbe battaiglia and Arenicola marina as well as sediment tests with the aquatic plant Myriophyllum spicatum, the chironomid Chironomus riparius, molluscs, Lumbriculus variegatus and the nematode Caenorhabditis elegans.
All studies are accompanied by state-of-the-art in-house analytical services. LC and GC devices are equipped with commonly used detectors (DAD, fluorescence, FID, ECD etc.) and mass spectrometry detectors. High resolution mass spectrometry allows for exact and sensitive detection of substances and metabolites. For detailed information, please refer to Chemical Analysis.
