Modeling Soil Water Distribution Of Aromatic Amines In Water Saturated Soil Systems

Examines in a pedagogical way all pertinent molecular and macroscopic processes that govern the distribution and fate of organic chemicals in the environment and provides simple modeling tools to quantitatively describe these processes and their interplay in a given environmental system Treats fundamental aspects of chemistry, physics, and mathematical modeling as applied to environmentally relevant problems, and gives a state of the art account of the field Teaches the reader how to relate the structure of a given chemical to its physical chemical properties and intrinsic reactivities Provides a holistic and teachable treatment of phase partitioning and transformation processes, as well as a more focused and tailor-made presentation of physical, mathematical, and modeling aspects that apply to environmental situations of concern Includes a large number of questions and problems allowing teachers to explore the depth of understanding of their students or allowing individuals who use the book for self-study to check their progress Provides a companion website, which includes solutions for all problems as well as a large compilation of physical constants and compound properties

This book provides a comprehensive overview of the current knowledge on the fate and interaction of pharmaceuticals in soil-crop systems. It addresses the principles of their transport, uptake and metabolism and reviews methodologies for their analytical determination. It also discusses ecotoxicological effects arising from their presence and highlights bioremediation approaches for their removal. The use of treated wastewater to irrigate crops is becoming more widespread in regions where freshwater is limited. This practice conserves freshwater resources and contributes to nutrient recycling. However, concerns remain regarding the safety of irrigation with treated wastewater since it contains residues of pharmaceuticals that have survived treatment, which means that soil and fauna are potentially exposed to these xenobiotics. Various pathways govern the fate of pharmaceuticals in crop-soil systems, including soil degradation; formation of non-extractable residues; uptake by soil-dwelling organisms (e.g. earthworms); and uptake, transport, and metabolism in agricultural crops. Investigations into these aspects have only recently been initiated, and there is still a long way to go before a meaningful assessment of the impact of wastewater has been completed.
