Analysis of Chemical Residues in Agriculture presents a focused, yet comprehensive guide on how to identify, evaluate and analyze the wide range of chemicals that impact our food production system. The book presents a variety of analytical technologies and methods in order to help professionals, researchers, and graduate and undergraduate students understand chemical residues in agriculture and apply them to applications for the detection and quantification of chemical residues - both organic and inorganic - in several agricultural matrices, including crops, fruits, meat, food, feed, soil and water.

Agriculture remains one of the most strategic sectors for the global economy and well-being. However, it is seen as a source of environmental and health concerns mainly due to the high amount of pesticides and fertilizers used in production systems around the world; moreover, a thorough understanding of the topic is necessary when we consider livestock production systems also apply large amounts of veterinary drugs to treat illness and promote increases in productivity.

Identifies the main scientific and technological approaches of analytical chemistry dedicated to agricultural and related matrices to solve real problems and for R&D purposes Provides a description of the analytical technologies and methodologies used to reduce the negative impact of several agrochemicals on the environment and health Explores cutting-edge analytical technologies to detect residues in agricultural and related matrices

This book addresses the highly relevant subject of emerging pollutants, which are especially alarming since most of the available treatment technologies are unable to degrade them. It discusses the sources of these pollutants and their fate in the environment, and the main tools available for their analysis. It also describes the representative environmental matrices (air, soil and water) and appropriate analytical methods for each matrix. Furthermore, it examines aspects of toxicology, chemometrics, sample preparation and green analytical chemistry.As such, it provides a broad overview of the potential analytical approaches for monitoring and controlling emerging pollutants.This book fills a gap in the literature, and is a valuable resource for all professionals concerned with emerging pollutant control in real-world situations.

This book covers lignin, a renewable source of carbonaceous material derived from biomass, which is a subject of research, development and innovation in both academia and industry.From lignin we can obtain chemicals (e.g., aromatics, phenols), materials (e.g., fibres, engineered plastics, modified polymers), specialties (e.g., additives as antioxidant), among other products in diverse levels of technology readiness. However, there are challenges to overcome in terms of chemical structure, industrial yields of conversion processes, and the quality of raw material in order to reach the best uses and applications according to the sustainability vision for products and processes. This book deals with the main biochemical pathways of synthesis; advanced analytical techniques; extraction strategies; chemical, biochemical, biological, and physical processing for chemicals and materials; circularity and sustainability aspects for actual and future production chains, allied to life cycle assessment and industrial ecology.

Accordingly, this book includes contributions from select international experts who discuss key aspects of biomass structure, their physical and chemical properties, the parameters of conversion processes, the products and by-products formation and quantification, and quality parameters.

This second edition expands on the foundational concepts of the first edition by incorporating cutting-edge research and emerging technologies for sustainable agriculture. In addition to updated chapters on green chemistry, toxicology, and agrochemical synthesis, it introduces new topics such as life cycle assessment of agrochemicals, photodegradation studies of lignin-based nanoformulations, pH-dependent sorption modeling for herbicides, and innovative approaches to sustainable fertilizers. With contributions from leading experts, this edition offers a comprehensive and forward-looking perspective on minimizing environmental impact while enhancing agricultural productivity.

This book deals with the application of techniques and methods of chemical analysis for the study of biomass and its conversion processes, aiming to fill the current gap in the book literature on the subject.The use of various techniques and analytical methods is presented and discussed in a straightforward manner, providing the reader with the possibility of choosing the most appropriate methodologies for analysis of the major classes of plant biomass and its products.In the present volume, a select group of international specialists describes different approaches to understand the biomass structure, their physical and chemical properties, the parameters of conversion processes, the products and by-products formation and quantification, quality parameters, etc.Modern chemistry plays a strong economic role in industrial activities based on biomass, with an increasing trend of the importance of its application from the deployment of biorefineries andthe principles of green chemistry, which make use of the potential of biomass with decreasing impact negative environmental. In this context, analytical chemistry can contribute significantly to the supply chains of biomass, be it plant or animal origin; however, with the first offering the greatest challenges and the greatest opportunity for technical, scientific and economic progress, given its diversified chemical constitution. Thus, the chemical analysis can be used to examine the composition for characterizing physicochemical properties and to monitor their conversion processes, in order to obtain better products and uses of biomass.The quality of the biomass used determines the product quality. Therefore, reliable information is required about the chemical composition of the biomass to establish the best use (e.g., most suitable conversion process and its conditions), which will influence harvest and preparation steps. Conversion processes should be monitored fortheir yield, integrity, safety, and environmental impact. Effluent or residues should be monitored and analyzed for environmental control. Co-products need to be monitored to avoid interference with the product yield and product purity; however, co-products are also a good opportunity to add value to the biomass chain. Finally, products need to be monitored and analyzed to determine their yields and purity and to ensure their quality. In this context, analytical chemistry can contribute significantly to the biomass supply chains, be it of plant or animal origin.
