Ecotoxicology is used to evaluate the effects of toxic substances on biological organisms at the species, community, and ecosystem levels.

Environmental Effects Testing

EcoAnalysts ecotoxicology laboratory in Port Gamble, WA offers bench-scale environmental effects testing. We are NELAP accredited for a suite of marine and freshwater sediment bioassays used to evaluate toxic effects and/or bioaccumulation of chemicals under controlled experimental conditions. The laboratory has specialized capabilities to replicate environmental conditions from tropic to arctic climates.

Our scientists support laboratory testing for a variety of industries and municipalities. We follow rigorous guidance related to permit criteria for permit holders. Additional services include logistics for sample collection and shipping, development of testing programs for proposed methodologies or test species, and communication and coordination with regulatory agencies.

Our services are provided under a variety of regulatory formats including USEPA and state NPDES permits. More than a regional laboratory, we work in the Northeast, Gulf Coast Region, Southwest, Northwest, the arctic, and internationally.

Specialized Capabilities

Unique in its design with the ability to provide a continuous flow of natural, filtered seawater, our ecotoxiology laboratory has specialized capabilities to replicate environmental conditions from tropic to arctic climates. The laboratory facility can be contracted to function as a custom research facility for your program.

  • 7000 feet of lab space

  • 2 climate controlled rooms

  • high capacity centrifuge for creating elutriates

  • passive sampling devices for sediment studies

A wide variety of freshwater and saltwater taxa are used to evaluate toxic effects and/or bioaccumulation of chemicals under controlled experimental conditions. In addition to routinely conducting standardized tests on an array of freshwater and marine organisms, we also develop and employ test methodologies with unique endpoints (such as edema differentiation using early life stages of fish) and new test species (Pacific herring, Arctic cod, the copepod Calanus glacialis, and freshwater mussels).
