This book was released on 2022-03-30 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available online: https://pub.norden.org/temanord2022-519/ On behalf of the Nordic Council of Ministers’ Screening Group, NILU and NIVA performed a monitoring study on selected environmental contaminants, namely UV-filters, dechloranes, and chlorinated paraffins. UV-compounds were frequently detected in samples related to the marine food web. In the group of dechloranes, dechlorane 602 was detected most frequently in samples related to the marine, freshwater, and terrestrial food web. Short and medium chain chlorinated paraffins (SCCPs and MCCPs) were found in most of the samples, but long chain chlorinated paraffins (LCCPs) with a slightly lower detection frequency. For nearly all biota samples, the concentrations of MCCPs were higher than the SCCP concentrations. LCCP-concentrations were as high or higher than the SCCP-concentrations.
Book Synopsis Chlorinated paraffins in urban air in Nordic Countries by : Bohlin-Nizzetto, Pernilla
Download or read book Chlorinated paraffins in urban air in Nordic Countries written by Bohlin-Nizzetto, Pernilla and published by Nordic Council of Ministers. This book was released on 2023-05-11 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Available online: https://pub.norden.org/temanord2023-515/ On behalf of the Nordic Council of Ministers’ Screening Group, NILU performed a study on short-, medium- and long-chain chlorinated paraffins (SCCPs, MCCPs, LCCPs) in urban air. Tire wear particles have been suggested to be a source for CPs and elevated urban concentrations of CPs. Air samples were here collected in three Nordic capitals (Finland, Iceland and Norway) in wintertime and in summertime. Higher concentrations of SCCPs and MCCPs were observed in wintertime than in summertime in Norway and Finland but no difference was observed in Iceland. Elevated concentrations of MCCPs and LCCPs were found at individual sites, but the concentrations at the urban sites were not consistently higher than at a background monitoring site. The results therefore showed no clear relationship to traffic. Instead, sources may be more diffusive and local sources seem to differ.
Book Synopsis Human Exposure to Chlorinated Paraffins in Scandinavia by : Yuan, Bo
Download or read book Human Exposure to Chlorinated Paraffins in Scandinavia written by Yuan, Bo and published by Nordic Council of Ministers. This book was released on 2023-04-17 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chlorinated paraffins (CPs) have received global attention by the authorities as well as the industries using or producing CPs. In late 2017, a group of short chain chlorinated paraffins (SCCPs) and replacement CPs were found in both Norwegian and Swedish mothers’ milk and, later, in mothers’ milk from over 50 countries across the world. his project focused on a comprehensive understanding of body burden and multiple human exposure pathways to both legacy CPs and current-use CPs in a Norwegian cohort. The cohort provided a rare opportunity to explore human exposure to CPs compared to the other consumer chemical contaminants. Combining both internal and external information, it was studied how much and to what extent people are exposed to the chemicals via different pathways, and what the differences are between the legacy CPs and the current CPs in human exposure and accumulation.
Book Synopsis Suspect screening in Nordic countries by : Martin Schlabach
Download or read book Suspect screening in Nordic countries written by Martin Schlabach and published by Nordic Council of Ministers. This book was released on 2017-10-26 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of a suspect screening study in samples from city areas in the Nordic countries. In contrast to target analysis, suspect screening starts with a general sample preparation and identification including as much compounds as possible. The resulting list of recorded compounds will be identified by comparison with a list of suspected compounds. Suspect screening has shown to be very useful for identification of emerging environmental pollutants. It was possible to identify: Perfluorinated compounds (PFC), chlorinated and brominated compounds, flame retardants, bisphenols, polycyclic aromatic compounds (PAC), industrial additives, and pharmaceuticals and personal care products (PPCP). This study was jointly performed by NILU, NIVA, and Umeå University on behalf of the Nordic Council of Ministers. The study was supervised by the Nordic screening group.

Book Synopsis Flame-Retardant Polymeric Materials by : Eli Pearce
Download or read book Flame-Retardant Polymeric Materials written by Eli Pearce and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flammability has been recognized as an increasingly important social and scientific problem. Fire statistics in the United States (Report of the National Commission on Fire Prevention and Control. "America Burning:' 1973) emphasized the vast devastation to life and property--12.000 lives lost annually due to fire. and these deaths are usually caused by inhaling smoke or toxic gases: 300.000 fire injuries: 11.4 billion dollars in fire cost at which 2.7 billion dollars is related to property loss: a billion dollars to burn injury treatment: and 3.3 billion dollars in productivity loss. It is obvious that much human and economic misery can be attributed to fire situations. In relation to this. polymer flammability has been recognized as an in creasingly important social and scientific problem. The development of flame-retardant polymeric materials is a current example where the initia tive for major scientific and technological developments is motivated by sociological pressure and legislation. This is part of the important trend toward a safer environment and sets a pattern for future example. Flame retardancy deals with our basic everyday life situations-housing. work areas. transportation. clothing and so forth-the "macroenvironment" capsule within which "homosapiens" live. As a result. flame-retardant polymers are now emerging as a specific class of materials leading to new and diversified scientific and technological ventures.
Book Synopsis Physical and Chemical Processes in the Aquatic Environment by : Erik R. Christensen
Download or read book Physical and Chemical Processes in the Aquatic Environment written by Erik R. Christensen and published by John Wiley & Sons. This book was released on 2014-09-15 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is need in environmental research for a book on fresh waters including rivers and lakes. Compared with other books on the topic, this book has a unique outline in that it follows pollution from sources to impact. Included in the text is the treatment of various tracers, ranging from pathogens to stable isotopes of elements and providing a comprehensive discussion which is lacking in many other books on pollution control of natural waters. Geophysical processes are discussed emphasizing mixing of water, interaction between water and the atmosphere, and sedimentation processes. Important geochemistry processes occurring in natural waters are described as are the processes specific to nutrients, organic pollutants, metals, and pathogens in subsequent chapters. Each of these chapters includes an introduction on the selected groups, followed by the physicochemical properties which are the most relevant to their behavior in natural waters, and the theories and models to describe their speciation, transport and transformation. The book also includes the most up to date information including a discussion on emerging pollutants such as brominated and phosphate flame retardants, perflurochemicals, and pharmaceutical and personal care products. Due to its importance an ecotoxicology chapter has been included featuring molecular biological methods, nanoparticles, and comparison of the basis of biotic ligand model with the Weibull dose-response model. Finally, the last chapter briefly summarizes the regulations on ambient water quality.
