Unbridled urbanization and development of natural land resources has led to the degradation of our surrounding environment. The air that we breathe, the water we drink and the food we eat is at risk of being contaminated with a plethora of chemical pollutants, some of them being potentially carcinogenic. This presents a challenge to human health. This book attempts to address this challenge in two parts which represent two different approaches. The first part of the book summarizes the alarming effects of environmental contaminants. Various studies depicting the direct relationship of environmental contaminants with cancer incidence have been referenced. Scientific studies have established an inverse relation between cancer and ingestion of dietary phytoconstituents (phytochemicals) in the form of fruits, vegetables and botanical herbs. Plant products as dietary supplements can suppress contaminant toxicity by regulating the resulting reactive species and also by assisting their bodily excretion through Phase 1 and Phase 2 enzyme metabolism. The second part of the book, shifts focus to phytoconstituents which, if included in diet, can prevent the harmful effects of pollutants. The text references numerous studies showing the anti-mutagenic, anti-genotoxic and anti-carcinogenic potential of many plant products. The combination of information about contemporary issues of carcinogenic contaminants in the environment coupled with the references to relevant studies in this handbook will enlighten readers studying courses in environmental chemistry, toxicology, botany, and ecology about environmental toxins and help them understand specific dietary measures known to reduce the toxic impact. Researchers in the field of nutrition can also benefit from the information provided.

Microbiome-Based Decontamination of Environmental Pollutants explores the complex interactions of plant-associated microbiomes, providing insights into the pressing challenges of managing environmental resources such as soil, water, and waste. Analysis has shown a formidable potential based in the network interactions between plant microbiota and environmental contaminants. This book presents insights into the potential exploitation of these plant-associated microbial functions. This volume in the Plant and Soil Microbiome series summarizes microbiological aspects of environmental management from the basics to advanced theoretical as well as practical aspects of microbial-based approaches. The physical and chemical changes caused by pollution of an ecosystem can occur rapidly, significantly impacting the functionality of ecosystem services in that environment. Environmental contamination poses and increasingly global challenge through direct and indirect adverse impacts on the climate, soil productivity and the health concerns of human beings. Traditional remediation techniques are not consistently feasible in mitigating environmental contaminants challenges in terms of cost-effectiveness, limited land resources and toxic residual products. The use of plant-associated microbes as part of a network of tools opens a new door to explore an alternative, eco-friendly and economical technology to mitigate the challenges of environmental contamination. Explores the emerging plant microbe interactive nexus for contaminants degradation Presents insights into the production and commercialization of plant-microbiome based enzymes Includes engineered microbes and microbial products application in contaminant management Highlights the latest omics and technologies used in plant–soil microbiome in contaminant management

How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.
