Sediment toxicity evaluation: their niche in ecological assessments, part 2
Article Abstract:
The extreme utility of toxicity testing has been demonstrated in various environmental and chemical hazard assessments. Extended applications of sediment toxicity tests are suggested for several environmental contaminant areas as current treatment technologies were found to be unable to provide information regarding their bioavailability or ecological relevance. As it was able to standardize its methods, sediment toxicity tests must now develop towards integrated ecological assessments.

Sediment quality and aquatic life assessment
Article Abstract:
The contamination of aquatic sediments poses a significant threat to the health of many species. Direct contact by many organisms with these sediments provides a means of transferring the hazardous chemicals from the sediment into the food chain. There are several methods available for assessing contamination levels, including equilibrium partitioning, apparent effects threshold evaluation, the sediment quality triad approach and the interstitial water toxicity method.

Assessing contaminated aquatic sediments
Article Abstract:
The Environmental Protection Agency is shifting its regulatory emphasis away from point sources of pollution to nonpoint sources. One of these nonpoint sources, contaminated sediments, has been shown by many studies to be one of the nation's most significant pollution problems. Research has yielded a number of new methods for assessing the extent of sediment contamination and for remediation of damage.
