This report describes a screening study of in all ninety-nine conventional and emerging per- and polyfluoroalkyl substances (PFASs) in the Nordic environment. In addition, extractable organic fluorine (EOF) was analysed. The latter can provide the amount, but not identity, of organofluorine in the samples, which in turn can be used to assess the mass balance between known and unknown PFASs. The study was initiated by the Nordic Screening Group and funded by these and the Nordic Council of Ministers through the Chemicals Group.A total of 102 samples were analyzed in this study, including bird eggs, fish, marine mammals, terrestrial mammals, surface water, WWTP effluents and sludge, and air. Samples were collected by institutes from the participating countries and self-governing areas; Denmark, Faroe Islands, Finland, Greenland, Iceland, Norway, and Sweden.
Children born to women exposed to thyroid-disrupting chemicals have lower IQs and more neurodevelopmental disorders in autism and ADHD, among others. Numerous chemicals that contaminate our bodies and interfere with our thyroids are in fact lowering our IQ and increasing disorders for future generations. A "self-help" guide to reducing exposure to chemicals is included.
This work demonstrates how understanding environmental science and theology can provide new resources for sustaining the Earth. With sidebars, discussion questions, and recommended readings, the book provides students with a text that nurtures both critical thinking and ethical action.
This book describes the huge efforts by the Chinese Government concerning the restoration and future sustainable management of Chinese water systems. It presents the results of a Sino-European joint project concerning the Songhuajiang-Liaohe River Basin (SLRB) in Northeast China conducted by the Chinese Research Academy of Environmental Sciences (CRAES), the Helmholtz Centre for Environmental Research - UFZ, Germany, and the Natural Environment Research Council as represented by the Centre for Ecology and Hydrology (CEH), UK. The book explains in great detail the development of risk assessment and corresponding management methods for (i) controlling water pollution, (ii) assessing river health and ecological restoration options, (iii) characterizing persistent organic pollutants (POPs), and (iv) protecting fragile groundwater resources. It also describes the implemented demonstration sites of SLRB during the project course as well as lessons learnt on efficient project management and the dissemination of knowledge and technologies.
An account of its settlement, growth, development and resources; an extensive and minute sketch of its cities, towns and villages, their improvements, industries, manufactories, churches, schools and societies; its war record, biographical sketches, portraits of prominent men and early settlers; the whole preceded by a history of Wisconsin, statistics of the state, and an abstract of its laws and constitution and of the constitution of the United States.
This book takes you on a journey through the hidden dangers lurking in your plate, providing a deeper understanding of the risks associated with foodborne illnesses. The book explores the science behind food contamination, from microbial pathogens to chemical hazards, and provides insights into how these threats can infiltrate the food supply chain. The book draws from the latest research and real-life case studies that shed light on the devastating consequences of consuming contaminated food. It serves as a practical guide to safeguarding your health and the health of your loved ones, covering effective mitigation strategies and the rigorous safety measures in place to protect the food you eat every day. Whether you’re a concerned consumer, a food industry professional, or simply curious about the intricacies of food safety, this book should be your go-to resource for navigating the complex landscape of foodborne risks and protecting what matters most – your well-being.
Per- and polyfluorinated alkyl substances (PFAS), have long been utilised in many household products including as firefighting foam to manage fires. However, PFAS have been linked to numerous adverse health effects leading to many class actions in US and other countries. This book, for the first time, discusses the dynamics of PFAS in the terrestrial environment by capturing from the literature the latest information on the composition of PFAS, nomenclature, measurements including many challenges relating to analytical science, presence of PFAS in the environment including their nature, fate and transport of PFAS, toxicity, regulatory considerations and risk and remediation. The book summari...
Per- and polyfluorinated alkyl substances (PFAS), often referred to as per- (and poly) fluorinated compounds (PFCs), have been used for years in many everyday3⁄4 and some lifesaving3⁄4 products. However, their use has been linked to adverse health effects in humans, a problem compounded by their persistence in the environment. This book discusses the various challenges of PFAS in our environment today, including their historical use as well as their chemical and toxicological properties. It also presents robust discussion of analytical challenges and special considerations in sampling. The work goes on to give practical recommendations for dealing with these compounds in today's dynamic ...
