Book Description
Soil organic matter (SOM) is the largest reservoir of organic carbon at the earth's surface. Its chemistry plays a crucial role in a wide range of issues including agricultural sustainability, pollution/contamination, and medicine. For instance, SOM is vital to soil fertility by affecting physical and chemical properties of soil and in controlling soil microbial activity by serving as a source for mineralizable C and N. Soil organic matter is also very influential in the transport and fate of organic and inorganic anthropogenic chemicals because of its heterogeneity and highly functionalized nature. Therefore, an understanding of SOM at the molecular level is a critical and worthwhile undertaking.
Bioavailability of Contaminants in Soils and Sediments

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.

Characterization of Natural Organic Matter in Drinking Water
Author: Jean-Phillipe CrouePublisher: American Water Works Association
ISBN: 1583210156
Category : Drinking water
Languages : en
Pages : 372
Book Description
The research reported on here sought to characterize natural organic matter (NOM) in dilute solutions and to isolate it without altering its properties, so that the effect of NOM in drinking water may be considered. Several NOM isolation methods were evaluated, including evaporation, reverse osmosis, nanofiltration, and adsorption. The effects of such isolation procedures on NOM's chemical composition and reactivity were considered. Based on these studies, the report presents conclusions regarding the feasibility and adequacy of in situ and ex situ techniques.
