Aquatic Toxicology

EAG provides a full complement of aquatic ecotoxicological testing services required to demonstrate the specific, acute and chronic effects of chemicals on living organisms for global product submissions. Static, semi-static and flow-through test systems with stringent environmental monitoring and control are in place to provide a wide variety of testing capabilities. Our staff has the expertise to implement specialized tests and to develop solutions for difficult problems.

  • Acute and chronic tests (growth, lifecycle, early life stage, sub acute, etc.)
    • Invertebrates, freshwater and marine (Daphnia and Ceriodaphnia sp., mysids and oyster)
    • Freshwater and estuarine fish (rainbow trout, bluegill sunfish, fathead minnow, common carp, zebrafish, medaka, stickleback, sheepshead minnow, atlantic silversides)
    • Amphibians (leopard frog, Xenopus sp., others as available)
    • Sediment dwellers and digesters (Chironomus riparius, Chironomus dilutus, Leptocheirus plumulosus, Lumbriculus variegatus, Hyalella azteca)
  • Bioaccumulation: Bioconcentration and biomagnification with fish, oysters and others on request
  • Non-GLP screening tests (e.g. product screening)
  • New developments with sediments
    • Acute and chronic toxicity testing (Chironomus, Hyalella, Lumbriculus, Leptocheirus)
    • Specific techniques developed to deal with highly absorptive materials
    • Bioaccumulation testing in sediment dwelling organisms
  • Endocrine Testing
    • Fish short-term reproduction assay (FSTRA)
    • Amphibian metamorphosis assay (AMA)
    • Medaka extended one generation reproduction test (MEOGRT)
    • Larval Amphibian Growth and Development assay (LAGDA)
