Book Description
This volume of the IARC Monographs provides evaluations of the carcinogenicity of some organophosphate insecticides and herbicides, including diazinon, glyphosate, malathion, parathion, and tetrachlorvinphos. Diazinon acts on a wide range of insects on crops, gardens, livestock, and pets, but most uses have been restricted in the USA, Canada, and the European Union since the 1980s. Glyphosate is the most heavily used agricultural and residential herbicide in the world, and has been detected in soil, air, surface water, and groundwater, as well as in food. Malathion is one of the oldest and most widely used organophosphate insecticides, and has a broad spectrum of applications in agriculture and public health, notably mosquito control. The insecticide parathion has been largely banned or restricted throughout the world due to toxicity to wildlife and humans. Tetrachlorvinphos is banned in the European Union, but continues to be used in the USA and elsewhere as an insecticide on animals, including in pet flea collars. The IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of these agents.

Book Description
Lee Johnson was a man with simple dreams. All he wanted was a steady job and a nice home for his wife and children, something better than the hard life he knew growing up. He never imagined that he would become the face of a David-and-Goliath showdown against one of the world’s most powerful corporate giants. But a workplace accident left Lee doused in a toxic chemical and facing a deadly cancer that turned his life upside down. In 2018, the world watched as Lee was thrust to the forefront of one the most dramatic legal battles in recent history. The Monsanto Papers is the inside story of Lee Johnson’s landmark lawsuit against Monsanto. For Lee, the case was a race against the clock, with doctors predicting he wouldn’t survive long enough to take the witness stand. For the eclectic band of young, ambitious lawyers representing him, it was a matter of professional pride and personal risk, with millions of dollars and hard-earned reputations on the line. For the public at large, the lawsuit presented a question of corporate accountability. With enough money and influence, could a company endanger its customers, hide evidence, manipulate regulators, and get away with it all—for decades? Readers will be astounded by the depth of corruption uncovered, captivated by the shocking twists, and moved by Lee’s quiet determination to see justice served. With gripping narrative force that reads like fiction, The Monsanto Papers takes readers behind the scenes of a grueling legal battle, pulling back the curtain on the frailties of the American court system and the lengths to which lawyers will go to fight corporate wrongdoing.

Book Description
The Shikimate Pathway gives a bird's eye view of the shikimate pathway and its implications for the life of a range of organisms. Topics covered in this book include the chemistry of intermediates in the shikimate pathway; biosynthesis of aromatic amino acids in this pathway; its metabolites; and its role in higher plants. This book is comprised of six chapters and begins by introducing the reader to shikimic acid, a natural product derived from the plant Illicium religiosum, along with the mechanistic and stereochemical aspects of the reactions of the shikimate pathway. The biosynthesis of aromatic amino acids from chorismate is also described, and then the discussion turns to the chemical properties and the detailed stereochemistry of intermediates and enzymes in the shikimate pathway. The next chapter examines the biosynthesis of isoprenoid quinones involved in electron transport and the folic acid group of co-enzymes in the shikimate pathway. The metabolism of the aromatic amino acids in microorganisms and higher organisms is considered, along with the biosynthesis and physiological functions of phenylpropanoid compounds and their derivatives in the shikimate pathway in higher plants. This book will be of general value to practitioners in the many and varied areas of biochemical research associated with metabolism.

Book Description
Chemical herbicides are widely used in food production throughout the world. At the present time, they represent approximately 40% of chemical products sales, followed by insecticides, fungicides, and other types of pesticides. Among these products, commercial formulations based on N-phosphonomethyl-glycine (PMG), commonly known as glyphosate, are the most used worldwide. Such herbicidal formulations play a key role in promoting crop yields. In Glyphosate: Chemistry, Uses and Safety Concerns review information on the presence of glyphosate-based herbicides in the environment, their potentially harmful effects, their influence on soil microbial communities and their capacity to adsorb to clay particles (which affects their environmental availability).The objective of the following work was to investigate the best way to achieve slow release of glyphosate using layered double hydroxides (LDHs) to minimize the environmental impacts of this herbicide. LDHs are also called anionic clays because they can host negatively charged species between their layers. They are best stabilized by anions with high charge density, such as carbonate. Understanding the release dynamics of glyphosate in homogeneous solutions of anions that are commonly found in the soil is important, since many crops require prior soil correction, altering the pH and also the availability of anions.In one study, the chelating capacity, coordination modes and structural chemistry of glyphosate with Ni (II) cations were investigated in solution and in the solid state. Glyphosate was purified from commercial Roundup WG (Monsanto), and characterized by 31P NMR, FTIR and melting point. The nickel complexes were prepared from Ni(NO3)2 solutions at pH = 8.0 and 4.0, and characterized by solid-state infrared spectroscopy (4000-150 cm-1) and elemental analysis (CHN). The solids were also studied by thermal analysis and X-ray absorption spectroscopy (XAS) using synchrotron radiation (LNLS, Brazil).Studies show that glyphosate has an oral absorption of 20 to 40% and is considered to be of low toxicity to mammals; however, recent research has shown that it can induce serious damage to mammalian cells. The authors examine suggested mechanisms of toxicity, including the blocking of mitochondrial oxidative phosphorylation, inhibition of cytochrome p450 activity, inhibition of intestinal arylhydrocarbohydroxylase activity, changes in glucose 6-phosphate dehydrogenase activity, DNA damage, hormonal changes, channel openings of calcium, and neurotoxicity involving NMDA receptor activation.The widespread and frequent use of glyphosate has increased concern about potential adverse effects on human health. Due to more stringent legislation on wastewater discharge and purity of drinking water, the authors discuss the development of an effective remediation technology for the decontamination of glyphosate. Although glyphosate residues can efficiently be removed by advanced technologies, the treatments are usually expensive and difficult to maintain. Therefore, different methods and options should be considered.

Book Description
The study of plant-microbe associations by new techniques has significantly improved our understanding of the structure and specificity of the plant microbiome. Yet, microbiome function and the importance of the plant’s microbiome in the context of human and plant health are largely unexplored. Comparable with our human microbiome, millions of microbes inhabit plants, forming complex ecological communities that influence plant growth and health through its collective metabolic activities and host interactions. Viewing the microbiota from an ecological perspective can provide insight into how to promote plant health and stress tolerance of their hosts or how to adapt to a changing climate by targeting this microbial community. Moreover, the plant microbiome has a substantial impact on human health by influencing our gut microbiome by eating raw plants such as lettuce and herbs but also by influencing the microbiome of our environment through airflow. This research topic comprising reviews, original and opinion articles highlights the current knowledge regarding plant microbiomes, their specificity, diversity and function as well as all aspects studying the management of plant microbiomes to enhance plant growth, health quality and stress tolerance.
