Permit Toxicity Testing
Acute Fish and Daphnia Bioassays
- Rainbow trout 96-hour LC50 test or LT50 test
- Daphnia magna (water flea) 48-hour LC50
Routine Bioassays for Government Permit Compliance (Environment Canada, WET, NPDES)
- Freshwater tests
- Daphnia magna and fathead minnow (Pimephales promelas)
Chronic Saltwater Tests
- Topsmelt (Atherinops affinis) and mussels (Mytilis edulis) according to EPA guidelines
- Chronic and Sublethal Aquatic Toxicity Evaluations
- Salmonid Early Life Stage Development Tests
- 7-day Embryo Alevin Test (E test)
- 30-day Embryo Alevin Test (EA test)
- 90-day Embryo Alevin Fry Test (EAF test)
- 7-day Ceriodaphnia dubia Survival and Reproduction
- 21-day Daphnia magna Survival and Reproduction
- 7-day Growth and Survival of fathead minnow, topsmelt or silverside
- 72-hour Freshwater Algal Growth Inhibition (Selenastrum capricornutum)
- Echinoderm Larval Development
Microtox® Testing The Microtox® Test uses a marine bacteria, Vibrio fischeri to examine potential effects to water, sediment and soil microbes.
- Liquid Phase
- Solid Phase
Note: Chronic Microtox® and Mutatox® tests are no longer supported by the manufacturer.
Toxicity Investigations for Industry and Government #80-12
- Designation of Dangerous Waste #80-12 To determine if a waste meets the definition of dangerous waste, the Washington Department of of Ecology (WDOE) requires a static acute fish toxicity test, which MAXXAM can perform.
- Antisapstain Tests for British Columbia – 0459X542 To determine if stormwater effluent from areas with treated lumber is acutely toxic, an acute 96-hr LT50 fish bioassay is required.
- Ocean Disposal Testing – CEPA 1999 Some material that is disposed of in the ocean may adversely affect marine organisms. MAXXAM analyzes sediment samples for acute and sublethal toxicity using three recommended tests: – Solid phase Microtox® – 10-d marine amphipod – Echinoderm fertilisation
