Influence of Potentially Confounding Factors on Sea Urchin Porewater Toxicity Tests
TLDR
Results from >40 sediment-quality assessment surveys using early–life stages of the sea urchin Arbacia punctulata were compiled and examined to determine acceptable ranges of natural variables such as pH, ammonia, and dissolved organic carbon on the fertilization and embryological development endpoints.
Development of Marine Toxicity Data for Ordnance Compounds
TLDR
The most sensitive toxicity test endpoints overall were the macroalga zoospore germination and the polychaete reproduction tests, and the most toxic ordnance compounds overall were tetryl and 1,3,5-trinitrobenzene.
Do amphipods have the same concentration‐response to contaminated sediment in situ as in vitro?
TLDR
An underlying assumption of laboratory‐based toxicity tests is that the sensitivity of organisms in the laboratory (in vitro) is comparable to that in the field (in situ), and estuarine amphipod sensitivity in vitro was equal to or greater than its sensitivity in situ.
Sediment Toxicity Identification Evaluation (TIE) Studies at Marine Sites Suspected of Ordnance Contamination
TLDR
The data suggest that some organic or organometallic contaminant(s) that were not included in the comprehensive suite of chemical analyses caused the observed toxicological responses.
Sediment toxicity and benthic communities in mildly contaminated mudflats
TLDR
Although benthic effects caused by present levels of contamination are not yet dramatic, subtle changes in community structure related to pollution may be occurring, multivariate analysis indicated that natural sediment characteristics and factors related to contamination may have been affecting community structure.
Short‐ and long‐term sediment toxicity test methods with the amphipod Grandidierella japonica
Methods are described for conducting flow-through sediment toxicity tests with the marine amphipod Grandidierella japonica. Short-term (10-d) exposures were conducted at 15°C in 1-liter beakers
