Methods for deriving pesticide aquatic life criteria for sediments.

摘要: Sediments represent an integral component of aquatic ecosystems that provide habitat and food sources for life. Although many international local governments have regulations in place to protect life, the majority these are focused on or based upon criteria conserving water quality, been years. After release aqueous environment, however, various organic chemicals tend accumulate sediments, where they may cause toxicity even when quality (WQC) met. comprise a complex medium pose unique challenges those who would like develop single numeric concentrations below which life is protected. Currently, no official US Environmental Protection Agency (USEPA) methods other agreed approaches available United States generating such sediment (SQC).
