Phytoremediation is the process that uses plants to remove pollutants from soils. These pollutants are stored in the edible parts of plants and if they are consumed above a certain level, they become a health risk for humans and animals. This book is a critical review of phytoremediation, its direct or indirect effects on food products, and the risks posed by this cost-effective technology in food safety. It shows how different plants are suited for phytoremediation, explains the role of toxicants in the environment, and analyses their effects and risks in the food chain at a global level. It also reviews the extraction methods of toxicants from plants after the phytoremediation process.Features Summarizes the phytoremediation technology for effective remediation. Describes different types of pollutants in soils that render food products useless. Identifies the role of phytoremediation in the environment and its advantages and disadvantages. Explains the role of phytoexclusion and phytostabilization in foods and food safety. Includes many case studies to describe the extraction protocols in postharvest for food safety. This book is intended for practitioners in public and private companies involved in soil remediation and food production, as well as graduate students and academics, in both developed and developing countries, who are involved in soil and environmental sciences, the food industry, agriculture, and biotechnology.

In the recent years, a wide variety of new chemicals continue to be developed as a result of industrial development and associated anthropogenic activities. The microbial contaminants in the environment, more precisely, antibiotic-resistant genes/bacteria produced as a result of mutation due to antibacterial drugs, are also considered emerging contaminants and specifically called emerging microbial contaminants such as sapoviruses, Waddlia chondrophila and Streptococcus parauberis. Pharmaceuticals and Personal Care products are a diverse group of compounds that includes ibuprofen, diclofenac, triclosan, antibiotics, anti-inflammatory agents, steroidal hormones, and active ingredients in soaps, detergents and perfumes which could find their way into food materials are tagged emerging contaminants.Given this, Emerging Contaminants in Food and Food Products discusses issues around the emerging contaminants in food and food products. Different types of contaminants, such as biological, chemical, organic, inorganic and microbial contaminants in foods, ways of detecting them and regulations surrounding global food safety are all covered.Features- Discusses all the categories of contaminants in food and food products. Biological, chemical, organic, inorganic, and microbial contaminants- Provides full information on emerging food contaminants, their effect on human and animal heath, and how it affects global food security and emerging technological applications in solving global problem.- Gives detection and prevention strategies and guideline policies on emerging contaminants of foods- Bring into account global perspectives on food contaminants and health implications.Also, this volume will serve as an information hub of emerging contaminants for scientists/researchers and professionals globally. This book is a good collection of independent chapters which presents full insights in the study of emerging contamination in food and the effects of these contaminants in humans and animals.

Soil is a complex system of inorganic and organic materials, living organisms, water, and air. It is home to more than one trillion species of microorganisms. Soil also plays an important role in the global carbon cycle. Because plants absorb carbon from the atmosphere, convert it to plant tissue, and return it to the soil as plant residue, soils globally act as the world's largest sink of active carbon. Soil has role to play in food production and safety. Soil contamination undermined by modern agricultural practices that deplete soil carbon stocks. Anthropogenic greenhouse gas emissions have been raising recorded temperatures since the Industrial Revolution. Greenhouse gas emissions from agriculture, forestry, and fisheries have almost doubled in the last 50 years and will increase by 30% by 2050 given the current trend. The primacy of arresting climate change is nowhere more evident than the adoption of 195 countries of the first legally binding global climate deal at the Paris Climate Conference in 2015. With atmospheric carbon dioxide (CO2) reaching 400 parts per million in 2016, soils can be an ally in bringing the CO2 level down to a sustainable level if protected for regeneration. Soil protection and regeneration is a technique that involves the conservative rehabilitation of soil ecosystem and farmland. This technique focuses on top soil regeneration, improving the water cycle, supporting biosequestration, enhancing ecosystem services, increasing biodiversity, strengthening the vitality and health of farm soil, and increasing resilience to climate change and landscape. Environmental protection not only improves soil health, productivity, and resilience to weather extremes, raising farm yields and income while strengthening regional food security in the face of a changing climate, but can also form part of a region's broader climate strategy. This book is timely as more studies and reviews need to be reported about regenerating global polluted soil and the impacts on the environment, the benefit of both biotic and abiotic structure, thereby creating more awareness of environmental protection and sustainability. Thus, this book presents a vista to research on regeneration of lost resources in the soil and its impacts on the environment.

Anthropogenic exercises as well as industrial enterprises and agricultural practices contribute considerably to the degradation and contamination of environment that considerably affects the soil. The normal physical and chemical know-hows soil washing used for soil remediation render the land useless as a medium for plant growth, as they take away all biological activities. Others are labour-intensive and have high maintenance value. Phytoremediation, a cheaper and sustainable in situ remediation techniques was so thought of. This book proposes enhanced solutions to issues of contamination and eventually convalescent sites and soils. However, plants don't have the aptitude to degrade several soil waste matters, particularly the inorganic pollutant. It's so imperative to require advantage of the degrading ability of soil microorganisms to assist various hyperacccumulator plants to remediate polluted soil. This book focuses on phytoremediation techniques improved by microbial colonies.
