Book Description
This report presents some of the results obtained on the bioevaluation of the standard elutriate test developed by the Environmental Protection Agency and the Corps of Engineers. Selected species of algae, bacteria, and protozoans were used as test organisms. Marine and freshwater species of each group were tested. Sediment samples were collected from four locations that are periodically dredged and water samples were collected from their corresponding disposal sites. The results of algal bioassays indicated both stimulatory and inhibitory effects when growth in the elutriate was compared to growth in disposal site water. The results are discussed in relation to water quality. Algal bioassays are one method of assisting the evaluation of the suitability of a particular dredged material for disposal. Bacteria and protozoans are important in the cycling of nutrients and toxicants but are not recommended as test organisms for water column effects.

Book Description
Dredged Material and Mine Tailings are two of the same thing once they are deposited on land: they must be safe-guarded, wash-out must be prevented, and they must be protected by a plantcover. This comprehensive treatise covers both important aspects of their management: In Chemistry and Biology of Solid Waste the principles and assessment are scientifically studied and discussed, while Environmental Management of Solid Waste turns to the practical applications, such as prediction, restoration and management. Previously, dredged material was a commodity, it could be sold as soil, e.g. to gardeners. In the meantime, dredged material from the North Sea (e.g. the Rotterdam or Amsterdam harbor) must be treated as toxic waste. Many environmentalists, managers and companies do not know how to solve the inherent problems. This new work deals with the chemical, physical and biological principles; the biological and geochemical assessment; the prediction of effects and treatment; and finally, with the restoration and revegetation. It is written by many leading scientists in the various fields, and will prove invaluable for scientists, managers and politicians who are concerned with the present environmental situation.
Ecological Risk Assessment

Languages : en
Pages : 564
Book Description
Recently, environmental scientists have been required to perform a new type of assessment-ecological risk assessment. This is the first book that explains how to perform ecological risk assessments and gives assessors access to the full range of useful data, models, and conceptual approaches they need to perform an accurate assessment. It explains how ecological risk assessment relates to more familiar types of assessments. It also shows how to organize and conduct an ecological risk assessment, including defining the source, selecting endpoints, describing the relevant features of the receiving environment, estimating exposure, estimating effects, characterizing the risks, and interacting with the risk manager. Specific technical topics include finding and selecting toxicity data; statistical and mathematical models of effects on organisms, populations, and ecosystems; estimation of chemical fate parameters; modeling of chemical transport and fate; estimation of chemical uptake by organisms; and estimation, propagation, and presentation of uncertainty. Ecological Risk Assessment also covers conventional risk assessments, risk assessments for existing contamination, large scale problems, exotic organisms, and risk assessments based on environmental monitoring. Environmental assessors at regulatory agencies, consulting firms, industry, and government labs need this book for its approaches and methods for ecological risk assessment. Professors in ecology and other environmental sciences will find the book's practical preparation useful for classroom instruction. Environmental toxicologists and chemists will appreciate the discussion of the utility for risk assessment of particular toxicity tests and chemical determinations.

Book Description
W.A. de Jong President of TNO Until some decades ago man supposed that the resilience of the environment was unlimited. He thought he could draw heavily on nature with impunity and that he could infinitely dump his waste into the environment. We have come to know better now: virtually everyone is well aware that one cannot just go on burdening the environment of man, animal and plant to such an extent. TNO, the Netherlands Organization for Applied Scientific Research, is among those research institutions that are working on economically feasible solutions for pollution problems resulting from human activities. Soil contamination and remediation feature as important topics in TNO's environmental research programme. In view of the international scope of the problem, TNO organized an international conference on this subject in Utrecht, the Netherlands, in November 1985, which met with a worldwide response from the scientific community as well as from governments and industry. The international interest taken in soil contamination is underlined by the fact that the Second International Conference on Contaminated Soil takes place in a country where remedial action is being given high political priority.
