Bioavailability of Contaminants in Soils and Sediments
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309086256
Category : Technology & Engineering
Languages : en
Pages : 433
Book Description
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.

Soil and Sediment Remediation
Author: Piet Lens
Publisher: IWA Publishing
ISBN: 1843391007
Category : Science
Languages : en
Pages : 545
Book Description
Soil and Sediment Remediation discusses in detail a whole set of remediative technologies currently available to minimise their impact. Technologies for the treatment of soils and sediments in-situ (landfarming, bioscreens, bioventing, nutrient injection, phytoremediation) and ex-situ (landfarming, bio-heap treatment, soil suspension reactor) will be discussed. The microbiological, process technological and socio-economical aspects of these technologies will be addressed. Special attention will be given to novel biotechnological processes that utilise sulfur cycle conversions, e.g. sulfur and heavy metal removal from soils. Also the potential of phytoremediation will be highlighted. In addition, treatment schemes for the clean-up of polluted megasites, e.g. harbours and Manufactured Gaswork Plants (MGP), will be elaborated. The aim of Soil and Sediment Remediation is to introduce the reader in: the biogeochemical characteristics of soil and sediments- new techniques to study soil/sediment processes (molecular probes, microelectrodes, NMR) clean up technologies for soils polluted with organic (PAH, NAPL, solvents) or inorganic (heavy metals) pollutants- preventative and remediative strategies and technologies available in environmental engineering novel process applications and bioreactor designs for bioremediation the impact of soil pollution on society and its economic importance.

Assessment of Bioavailability of Polycyclic Aromatic Hydrocarbon (PAH) in Coal-tar Contaminated Soils
Author: Insoo Joo

ISBN:

Languages : en
Pages : 198
Book Description
The bioavailability of polycyclic aromatic hydrocarbons (PAHs) in coal-tar contaminated soils plays an important role in determining the risk of these compounds to the environment and humans. Developing an understanding of organic compounds bioavailability will assist in improving risk assessment and developing bioremediation strategies. In the first part of study, the degradation of 16 EPA priority PAHs in soil slurry reactors were investigated along with the change in microbial population. Using DAPI-stained organisms, maximum microbial populations were found to correspond with the depletion of 2- and 3-ring PAHs. Degradation of PAHs was sequential with the 2- and 3-ring PAHs degrading first, followed by the 4- and 5-ring PAHs. There was negligible degradation of 6-ring PAHs. The Modified Gompertz equation, an empirical model, was used to estimate the lag phase, degradation rate, and maximum degraded fraction of individual PAHs. The Monod equation was also applied but did not model the experimental data well especially the change in microorganism population. In the second part of study, several chemical methods were performed to assess the bioavailability of PAHs in three coal-tar contaminated soils from former manufactured gas plant (FMGP) sites. The methods tested were hydroxypropyl-[beta]-cyclodextrin (HPCD), persulfate oxidation, acetone-water mixture extraction, butanol extraction, and solid phase extraction using XAD-2. Residual PAHs in each soil following extraction were compared with the PAHs remaining after biodegradation in soil slurry reactors. Of the five methods tested, the XAD-2 desorption method was determined to the best method for predicting the bioavailability in coal-tar contaminated soils.

Bioavailability of Organic Chemicals in Soil and Sediment
Author: Jose Julio Ortega-Calvo
Publisher: Springer Nature
ISBN: 3030579190
Category : Science
Languages : en
Pages : 428
Book Description
This book discusses bioavailability concepts and methods, summarizing the current knowledge on bioavailability science, as well as possible pathways for integrating bioavailability into risk assessment and the regulation of organic chemicals. Divided into 5 parts, it begins with an overview of chemical distribution in soil and sediment, as well as the bioavailability and bioaccumulation of chemicals in plants, soil, invertebrates and vertebrates (including humans). It then focuses on the impact of sorption processes and reviews bioavailability measurement methods. The closing chapters discuss the impact of bioavailability studies on chemical risk assessment, and highlights further research needs. Written by a multi-disciplinary team of authors, it is an essential resource for scientists in academia and industry, students, as well as for authorities.
