The latter part of the book describes the landscape of bio-based materials, the eco-consumer, and insights into the industry problem of "greenwashing.¿ This book is a valuable resource for industry professionals who use polyurethanes in the supply chain for manufactured products, those in sales and marketing or regulatory roles who wish to better understand the unique advantages of bio-based materials, and researchers studying R&D of biobased polyurethanes or remediation of microplastics pollution on land and in bodies of fresh and saltwater worldwide.

Herbicides: Chemistry, Efficacy, Toxicology, and Environmental Impacts addresses contemporary debates on herbicide toxicology. The reader is offered a comprehensive overview of this complex topic, presented by internationally recognized experts. Information presented will inform discussions on the use of herbicides in modern agricultural and other systems, and their potential non-target effects on human populations and various ecosystems. The book covers these matters in concise language appropriate to engage both specialists in the research community and informed persons responsible for legislative, funding, and public health matters in the community at large. The use of herbicides is an essential pillar of modern agricultural production systems. Weeds, if uncontrolled, would reduce crop yield and result in massive economic damage. Recently, the heavy reliance on single herbicides has been linked to the development of weed resistance. To combat resistant weeds, farmers are advised to use a mix of several herbicides and to increase herbicide application rates. As a result, the toxicity of herbicides on human health and the environment has become a controversial topic. Offers a comprehensive overview of herbicide science in modern agricultural systems Addresses the complex problems that can arise from herbicide use and misuse, including weed resistance, pollution, and human health issues Uses recent examples to demonstrate the topical nature of this issue

A volume in the Emerging Issues in Analytical Chemistry series, The Analytical Chemistry of Cannabis: Quality Assessment, Assurance, and Regulation of Medicinal Marijuana and Cannabinoid Preparations provides analytical chemistry methods that address the latest issues surrounding cannabis-based products. The plethora of marketed strains of cannabis and cannabinoid-containing products, combined with the lack of industry standards and labelling requirements, adds to the general perception of poor quality control and limited product oversight. The methods described in this leading-edge volume help to support the manufacturing, labelling, and distribution of safe and consistent products with known chemical content and demonstrated performance characteristics. It treats analytical chemistry within the context of the diverse issues surrounding medicinal and recreational cannabis in a manner designed to foster understanding and rational perspective in non-scientist stakeholders as well as scientists who are concerned with bringing a necessary degree of order to a field now characterized by confusion and contradiction.

Shale oil and gas have altered the energy landscape, possibly permanently. They burst upon the fossil energy scene with a suddenness that initially defied prediction. Even the political balance of the world has changed. But, with the methods employed, the vast majority of the oil and gas remains in the ground. At the same time, serious environmental impact issues have been raised. A new volume in the Emerging Issues in Analytical Chemistry series, Sustainable Shale Oil and Gas Production: Analytical, Biochemical, and Geochemical Methods was written on the premise that analytical methods to inform these areas were wanting. While not attempting to be comprehensive, it describes important analytical methods, some still in development. These methods are underpinned primarily by chemistry, but geochemistry and even biochemistry play significant roles. The book has a solutions flavor; problems are posed together with approaches to ameliorate them.Provides a clear understanding of the potential environmental issues as well as a path to solutionsIncludes background information for understanding potential impacts of shale operations from both an environmental and public health perspectiveAuthored by leaders from diverse disciplines with expertise in a variety of areas: groundwater quality, petroleum-related operations, microbial ecology, and electronic technologiesReviews new sensing and evaluation methods that could be key enablers to sustainable fracking: portable mass spectrometry, microbiome analysis, DNA as tracers, and a microparticulate matter detector
