We have experience in addressing special questions in environmental risk assessment with acute and chronic laboratory tests with non-standard species and/or non-standard design.

Possible test species are for example:

Insects:

• Mayflies (e.g. Cloeon dipterum)
• Caddiesflies (e.g. Hydropsyche incognita, Lasiocephala basalis, Rhyacophila spp.)
• Phantom midges (e.g. Chaoborus obscuripes, Chaoborus crystallinus
• Water bugs (e.g. Notonecta glauca)

Crustacea:

• Isopods (e.g. Asellus aquaticus)
• Amphipods (e.g. Gammarus pulex, Gammarus roeselii, Crangonyx pseudogracillis)
• Cladocera (e.g. Daphnia longispina, Daphnia pulex, Simocephalus sp.)

Mollusca:

• Gastropoda (e.g. Potamopyrgus antipodarum, Lymnea stagnalis)

Oligochaeta:

• Naididae
