"A baseline environmental characterization of the inner Kachemak Bay, Alaska was conducted using the sediment quality triad approach based on sediment chemistry, sediment toxicity, and benthic invertebrate community structure. The study area was subdivided into 5 strata based on geophysical and hydrodynamic patterns in the bay (eastern and western intertidal mud flats, eastern and western subtidal, and Homer Harbor). Three to seven locations were synoptically sampled within each stratum using a stratified random statistical design approach. Three sites near the village of Port Graham and two sites in the footprint of a proposed Homer Harbor expansion were also collected for comparison. Concentrations of over 120 organic and metallic contaminants were analyzed. Ambient toxicity was assessed using two amphipod bioassays. A detailed benthic community condition assessment was performed. Habitat parameters (depth, salinity, temperature, dissolved oxygen, sediment grain size, and organic carbon content) that influence species and contaminant distribution were also measured at each sampling site"--Executive summary.

Sediment Toxicity Assessment provides the latest information regarding how to evaluate sediment contamination and its effects on aquatic ecosystems. It presents an integrated ecosystem approach by detailing effective assessment methods, considerations, and effects to each major component of marine and freshwater systems, including the benthos, plankton, and fish communities. The approaches emphasize defining habitat conditions (physical and chemical), toxicant bioavailability, factors influencing toxicity (lab and field), biomarkers, acute and chronic toxicity, study design, collection methods, and EPA management strategies. The book also explains how to integrate the assessments. Sediment Toxicity Assessment will be useful to to all environmental managers, environmental scientists, ecotoxicologists, environmental regulators, aquatic ecologists, environmental contractors and consultants, instructors, students, conservation commissions, and environmental activist organizations.

Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.
