“This book uses Caenorhabditis elegans as model animal to introduce the toxicity induction of toxicants at environmentally relevant concentrations under different conditions. It also discusses the systematic introduction of different molecular signaling pathways, as well as G protein coupled receptors and ion channels, in regulating the toxicity of toxicants at environmentally relevant concentrations.

A "zero waste" society and the "circular economy" trend are urgently needed. Even if achieving 100% trash recycling and a fully circular economy may not always be attainable, aiming toward this goal might result in a sustainable future. Municipal solid wastes pose a hazard to the environment because of open burning, landfills, reckless disposal, and many other factors. Waste is being thrown away in more significant quantities and is made up of several different materials. Municipal solid waste (MSW) characteristics must be carefully considered when developing, implementing, or modifying solid waste management systems. Local waste variables that vary with cultural, climatic, socioeconomic, and institutional capacities are crucial for developing efficient waste management techniques.

Arsenic contamination in drinking water and crops is a major health issue in many countries worldwide, threatening the health of millions of people due to arsenic’s toxicity and carcinogenicity. This edited volume brings together a diverse group of environmental science, sustainability and health researchers to address the challenges posed by arsenic contamination. The book sheds light on this global environmental issue and proposes solutions to aquatic contamination through multi-disciplinary sustainable approaches and case studies from different parts of the world. The chapters contained here present the status quo in different parts of the world and provide essential information on arsenic exposure risks for humans as well as possible measures for tackling arsenic poisoning. The mechanisms of arsenic uptake, translocation and distribution in plants and grains are also explained. In closing, the book reviews a variety of prospective sustainable solutions to the problem of arsenic accumulation in soil and water.

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 book characterizes the major pollution patterns of emerging contaminants, such as sources, emission effluents, temporal and spatial distributions, multi-media transportation and transformation processes, exposure pathways to ecosystems and humans, and ecological risks. Based on this, it establishes an urbanizing region management concept and highlights how urbanization and its regional ecology have evolved into a more integrated vision. It also decouples the relations between urbanization and emissions of emerging pollutants that are framed within a broad socio-ecological context considering institutions, policies, and governance. All the theory, methods, and case studies have been taken from the authors’ publications, which have undergone rigorous international peer review.

This book presents an overview of the techniques available today for the removal of fluoride contamination/pollutants/species from water. Also covered are traditionally applied techniques for the removal of fluoride pollutants/species, including oxidation, coagulation-flocculation, and membrane techniques. Recently, progress has been made on the utility of various nanoparticles for the extraction of contaminants from water. Fluoride contamination is affecting water resources quality worldwide as a result of human activities, such as mining and pesticide use. Due to the high risk of fluoride exposure, specific water treatment processes are required to meet more severe water quality standards. A better understanding of currently available processes is necessary to develop economical, efficient, and effective methods for fluoride removal. Fluoride can either be coated, adsorbed using a wide range of both mineral and organic constituents or can be directly rejected by membrane processes, such as reverse osmosis and nanofiltration. Recent developments of submerged hybrid membrane systems, such as membrane bioreactors in wastewater treatment, provide alternative technologies for fluoride treatment.

It’s easy to feel powerless in the face of big environmental challenges—but we need inspiration more than ever. With political leaders who deny climate change, species that are fighting for their very survival, and the planet’s last places of wilderness growing smaller and smaller, what can a single person do? In Nature’s Allies, Larry Nielsen uses the stories of conservation pioneers to show that through passion and perseverance, we can each be a positive force for change.

This book delivers an outline to graduate, undergraduate students, and researchers, as well as academicians who are working on lead toxicity with respect to remediation. It covers sources of lead contamination and its impact on human health and on prospective remediation through multi-disciplinary approaches with application of recent advanced biological technology. Lead is among the elements that have been most extensively used by man over time. This has led to extensive pollution of surface soils on the local scale, mainly associated with mining and smelting of the metal and addition of organic lead compounds to petrol. Release of lead to the atmosphere from various high-temperature processes has led to surface contamination on the regional and even global scale. In addition, plants grown on lead-rich soils incorporate lead, and thus, the concentration of lead in crop plants may be increased. Lead enters in the food chain through consumption of plant material. A high concentration of lead has been found to be harmful to vegetation. As the lead concentration increases, it adversely affects several biological parameters and eventually renders the soil barren. This edited book brings together a diverse group of researchers to address the challenges posed by global mass poisoning caused by lead contamination of soil and plants. The book sheds light on this global environmental issue and proposes solutions to contamination through multi-disciplinary approaches. This book contains three sections. The first section describes the different sources and distribution of lead in soil and plant ecosystems. The second section explains the health risks linked to lead toxicity. The third section addresses sustainable lead toxicity mitigation strategies and the potential applications of recent biological technology in providing solutions. This book is a valuable resource to students, academics, researchers, and environmental professionals doing fieldwork on lead contamination throughout the world.
