Evaluation of interstitial water as a route of exposure for ammonia in sediment tests with benthic macroinvertebrates
Ammonia commonly is present at detectable concentrations in overlying and interstitial water in solid-phase sediment toxicity tests. There are scenarios in which it is desirable to discern ammoniaExpand

Effects of Chironomus tentans larval growth retardation on adult emergence and ovipositing success: implications for interpreting freshwater sediment bioassays
A laboratory study was conducted with Chironomus tentans to assess the significance of growth retardation of third-to fourth-instar larvae over a 10-d test period on long-term survival, adultExpand
