Global Contamination Trends of Persistent Organic Chemicals


Book Description

Environmental pollution by man-made persistent organic chemicals (POCs) has been a serious global issue for over half a century. POCs are prevalent in air, water, soil, and organisms including wildlife and humans throughout the world. They do not degrade and cause long-term effect in organisms. Exposure to certain POCs may result in serious environ




Per and polyfluorinated substances in the Nordic Countries


Book Description

This Tema Nord report presents a study based on open information and custom market research to review the most common perfluorinated substances (PFC) with less focus on PFOS and PFOA. The study includes three major parts:1) Identification of relevant per-and polyfluorinated substances and their use in various industrial sectors in the Nordic market by interviews with major players and database information; 2) Emissions to and occurence in the Nordic environment of the substances described in 1); 3) A summary of knowledge of the toxic effects on humans and the environment of substances prioritized in 2); There is a lack of physical chemical data, analystical reference substances, human and environmental occurrence and toxicology data, as well as market information regarding PFCs other than PFOA and PFOS and the current legislation cannot enforce disclosure of specific PFC substance information.




Marine Pollution and Marine Waste Disposal


Book Description

Marine Pollution and Marine Waste Disposal documents the proceedings of the 2nd International Congress held in San Remo on December 17-21, 1973. This book is divided into seven main topics—general problems of marine pollution; criteria for marine waste disposal; marine water quality problems; assessment in biological terms of the effects on marine environment; design of treatment and disposal systems; experience with marine waste disposal systems; and research on marine pollution. In these topics, this compilation specifically discusses the need for international cooperation in coastal resource quality management; criteria for marine waste disposal in Yugoslavia; viral pollution considerations in marine waste disposal; and major pollutants in the marine environment. The conceptual design of marine waste disposal systems; pollution of coastal waters in Italy; and Southern California coastal water research project findings are also covered. This publication is valuable to marine biologists and environmentalists concerned with marine pollution and waste disposal systems.







PFASs in the Nordic environment


Book Description

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.




The cost of inaction


Book Description

PFAS (per and polyfluoroalkylsubstances) are known to be extremely difficult to degrade in the environment and to be bioaccumulative and toxic. Exposure to PFAS is suspected to increase the risk of adverse health effects, such as impacts on the thyroid gland, the liver, fat metabolism and the immune system. This study estimates the socioeconomic costs that may result from impacts on human health and the environment from the use of PFAS. Better awareness of the costs and problems associated with PFAS exposure will assist decision-makers and the general public to make more efficient and timely risk management decisions. Findings indicate that the costs are substantial, with annual health-related costs estimated to 2.8 – 4.6 billion EUR for the Nordic countries and 52 – 84 billion EUR for all EEA countries. Overall non-health costs are estimated at 46 million – 11 billion EUR for the Nordic countries.Upon request the excel spreadsheets used for the monetarisation and valuation in this report can also be provided along with a guidance on how to use the estimation of costs for value transfer. Please contact any of the consultants or members of the steering group from the Swedish Chemicals Agency or the Danish Environmental Protection Agency if you are interested in receiving these excel spreadsheets.




Chemistry and Analysis of Volatile Organic Compounds in the Environment


Book Description

Interest in the occurrence and behaviour of volatile organic compounds (VOCs) is increasing due to their adverse effects on the environment and human health. It is essential that information is made available on the various aspects of research on VOCs to enable better understanding and control of the various environmental and human health threats. The information in this book will be used to improve communication and understanding of the various approaches. In particular the potential and limitations of the described analytical methods will be essential in defining environmental studies and interpreting the results.




Microplastics in Water and Wastewater


Book Description

This book covers the topic of microplastics in water and wastewater. The chapters start with introductory issues related to the growing interest in the scientific community on microplastics and the human water cycle and point out where the microplastics could interact with water. The subsequent chapters examine evidence of the microplastic presence in freshwater, such as in both rivers and lakes, in freshwater biota, and hazardous chemicals associated with microplastics in such systems. Another set of chapters discuss the presence of microplastics in wastewater: their sources; their transfer through a wastewater treatment plant; the concentration of microplastics in effluents throughout the world; the plastic biomedia used in wastewater treatment plants and the effect on the surrounding environment of effluent wastewater pipes. These chapters also discuss the sampling methods, the sample treatment and analysis techniques used so far for microplastics in wastewater. Additionally, the presence of microplastics in sewage sludge and in soils irrigated with wastewater or fertilized with sludge are discussed. The possible impact of plastics and their additives on plants, microalgae, and humans are reviewed and presented in a critical way. Finally, a chapter summarizes all the relevant regulations and initiatives that point to the necessity of a global directive for the protection of the environment from plastic and microplastic pollution. The topic of microplastics in freshwater systems and in wastewater has scarcely been studied and requires more attention. Microplastics in Water and Wastewater aims to bring these initial findings to the attention of a broader audience and especially to operators and managers of freshwater and wastewater systems. It will also be helpful to people already aware of the marine debris problem to understand the sources of microplastics in the oceans, from freshwater systems and wastewater treatment plants.
