Phytochemicals have been present in human diet and life since the birth of mankind, including the consuming of plant foods and the application of herbal treatments. This coevolutionary interaction of plants and people has resulted in humans' reliance on food and medicinal plants as sources of macronutrients, micronutrients, and bioactive phytochemicals. Phytochemicals can be used as adjuvant agents and sensitizers in traditional antibiotic and anticancer therapy, reducing the potential of selecting resistant microbial strains and cancer cells. Recent Frontiers of Phytochemicals addresses the many processes of potential phytochemical evaluation of known sources, with a focus on phytochemical and pharmacological evaluations, and computational research into the structures and pharmacological mechanisms of natural products and their applications in medicine, food and biotech.

"In Petrochemical Planet Alice Mah examines the changing nature of the petrochemical industry as it faces the existential threats of climate change and environmental activism. Drawing on research from high-level industry meetings, petrochemical plant tours, and polluted communities, Mah juxtaposes the petrochemical industry's destructive corporate worldviews with environmental justice struggles in the United States, China, and Europe. She argues that amid intensifying public pressures, a profound planetary industrial transformation is under way that is challenging the reigning age of plastics and fossil fuels. This challenge comes from what Mah calls multiscalar activism-a form of collective resistance that spans local, regional, national, and planetary sites and scales and addresses the interconnected issues of environmental justice, climate, pollution, health, extraction, land rights, workers' rights, systemic racism, and toxic colonialism. Reflecting on the obstacles and openings for critical interventions in the petrochemical industry, Mah challenges offers important insights into the possibilities for resistance and developing alternatives to the reliance on fossil fuels"-- Provided by publisher.

This book on biogas is about the production and use of biogas with an emphasis on the raw materials and processes suitable for use in Southeast Asia. It is a gas formed when organic matter decomposes in an anaerobic digestion process. It can be made from any organic substance but the most economic are organic products from waste such as agricultural or general household waste, sewage, manure, municipal waste or food waste. As this raw material can be renewed indefinitely, biogas produced from it, is considered a renewable energy source. Worldwide interest in renewable energy sources is gathering momentum especially as concern for climate change mounts. Biogas generation helps reduce reliance on the use of fossil fuels. Producing biogas through biodigestion is non-polluting as there is no combustion or energy addition especially in the warmer climes of Southeast Asia. In this region, poorly managed landfills allow toxic liquids to drain into underground water sources. If instead, these wastes were used in a biogas plant, water pollution would be reduced. The same argument could be made for the local air quality. Therefore, biogas generation, in addition to producing renewable energy, also improves local water and air quality. The solid end-waste product of the biogas generation process is enriched natural organic matter (digestate), which can be substituted for chemical fertilizers, providing another environmental benefit to biogas. This book is primarily concerned with the production of biogas. From the raw material pre-treatment to the reactor design and operation to the post-treatment system, this book covers all aspects of production. There are many types of biogas reactors, each with their own advantages. Which reactor to select depends on the type and quantity of raw material, land area available and climate, among other factors. This book provides information on selecting and operating a suitable biogas system for interested parties be they governmental, NGO’s, private companies or individuals. Biogas contains primarily methane (CH4) and carbon dioxide (CO2). It may also contain small quantities of carbon monoxide (CO), hydrogen sulfide (H2S), moisture and siloxanes. Extracting the methane from all other gases is called biogas upgrading and the output is then referred to as biomethane. These upgrading processes are not the subject of this book as they are already the subject of a previously published book.

"Beneficial elements like Aluminium (Al), cobalt (Co), sodium (Na), selenium (Se), and silicon (Si) play a vital role in plant growth. They reportedly increase a plants tolerance against biotic stress, like pathogens and herbivory, and to abiotic stresses such as drought, salinity, and nutrient toxicity or deficiency. Although these elements increase the growth and development of various plants against the fluctuating environmental conditions, their concentration and way of function varies for each plant in different conditions. These beneficial elements are not necessary for plants, but when provided, they benefit their growth subsequently, and can stimulate mechanisms of resistance to fluctuating environmental conditions and also promote the uptake of other nutrients and reimburse the toxic impacts of other elements."--

Environmental Contaminants and Endocrine Health focuses specifically on contaminants with hormonal disrupting activities. The book provides insights into the multiple effects of endocrine-disrupting chemicals (EDCs) and their mechanism of action (MoA) on metabolism, reproduction and the multiple physiological roles of the endocannabinoid system which has recently been indicated as new target. The content systematically covers EDC sources and effects, EDCs as sources of disease and health impairment in laboratory models, EDCs as the cause of disease and health impairment in humans and wild species, and the removal of hazardous pollutants from wastewaters to highlight intervention, mitigation and adaptation for reduced threat.
