Sediment Toxicology

Sediments play an important role in aquatic ecosystems since they serve as a source and sink for organic and inorganic materials. Sediment toxicity tests and bioassays are important tools for regulators and scientists researching toxicity, bioaccumulation and bioavailability of chemicals to benthic organisms.

SSL Sediment Testing Experience Includes:

U.S. EPA (1989). Developed and validated test procedures with the marine amphipod Ampelisca abdita for use in measuring sediment quality.
BBA Guidelines (1994). Participated in an international ring-test to evaluate midge emergence in a long-term toxicity test with Chironomus riparius.
Environment Canada (1996). Participated in an inter-laboratory ring-test to develop and standardize a 14-day sediment exposure with Hyalella azteca.
U.S. EPA (1996). Participated in an inter-laboratory evaluation of U.S. EPA sediment acute toxicity test methods with H. azteca and Chironomus tentans.
U.S. EPA (1996-1997). Participated in development and evaluation of chronic test methods for H. azteca and C. tentans
