Available in PDF, EPUB and Kindle. Book excerpt: "Bottom and suspended sediment was collected from the St. Lawrence River between Kingston and Cornwall inJuly 1981 by the Water Quality Branch, Ontario Region. Samples were analyzed for organochlorine pesticides, PCBs, chlorobenzenes and organic carbon. Particle size distribution was determined on bottom sediment. This report summarizes the concentration and distribution of the trace organic contaminants and compares findings with other available historical data. Total PCBs were compared with the Ontario Ministry of Environment dredged material guideline for open water disposal"--Abstract, p. v

Download or read book Bioavailability of Contaminants in Soils and Sediments written by National Research Council and published by National Academies Press. This book was released on 2003-05-03 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Available in PDF, EPUB and Kindle. Book excerpt: "This study provides information on sediment bacterial responses to the in-situ sediment pollutants in Lake St. Louis in the St. Lawrence River, spatial distributions possibly indicating sources and contaminant sinks. The study provides information on the usefulness of microbial communities to evaluate the nature and extent of sediment pollutants in an aquatic ecosystem. The data summarized in this report provide information on the relationship between microbial populations and the concentrations of trace elements in sediments in Lac St. Louis, St. Lawrence River. The information is useful for the evaluation of the response of microbial processes in aquatic sediments to pollutants"--Executive summary.

Download or read book Hydrodynamics and Sediment Dynamics of Tidal Inlets written by David G. Aubrey and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Along much of the shoreline of the world, tidal inlets play an important role in nearshore processes, providing links between the coastal oceans and protected embayments. Their study is of particular importance not only for the understanding of fundamental processes in coastal oceanography but also for engineering and the proper management of the delicate equilibrium of our shorelines. This volume, based on the International Symposium on Hydrodynamics and Sediment Dynamics of Tidal Inlets held at Woods Hole, MA, presents the reader with an overview of contemporary research on these important features. The coverage includes: - mathematical modelling, including a review of inlet hydrodynamics, - observations on hydrodynamics, - sedimentology and morphology, - tidal deltas, - processes and policies pertaining to sedimentation, and the - impacts of shore protection and dredging in beaches.
