Bioavailability of Organic Chemicals in Soil and Sediment
Author: Jose Julio Ortega-CalvoPublisher: 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.
Bioavailability of Contaminants in Soils and Sediments

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.

Changes in Biodegradation and Toxicity Because of Pollutant Sequestration in Soil
Author: Martin AlexanderPublisher:

Pages : 11
Book Description
Organic compounds were shown to become sequestered in soil with a consequent decrease in biodegradability, availability for animal uptake, and toxicity. The rate and extent of sequestration varied among soils with dissimilar properties. Sequestration could be increased or decreased by appropriate soil treatments. Sequestration and bio-remediation caused a marked diminution in availability of organic compounds to animals. Because of sequestration, current methods for analysis give inappropriate estimates of exposure and risk from persistent pollutants. Analytical methods to assess changes in bioavailability resulting from sequestration were developed. Among the compounds/evaluated were several polycyclic aromatic hydrocarbons, triazines, and chlorinated hydrocarbons. Data were obtained in support of hypotheses suggesting that nanopores or partitioning into organic matter is responsible for sequestration.

Book Description
This book addresses the interactions of soil minerals with organics and microbes and their impacts on the dynamics, transformations, and toxicity of metals, metalloids, other inorganics, and xenobiotics that affect land quality and ecosystem health. It is the result of the work group on "interactions of soil minerals with organic components and microorganisms" in the International Society of Soil Science.
