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 Screening of Chlorinated Paraffins, Dechloranes and UV-filters in Nordic Countries by : Schlabach, Martin
Download or read book Screening of Chlorinated Paraffins, Dechloranes and UV-filters in Nordic Countries written by Schlabach, Martin and published by Nordic Council of Ministers. 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 Per and polyfluorinated substances in the Nordic Countries by : Stefan Posner
Download or read book Per and polyfluorinated substances in the Nordic Countries written by Stefan Posner and published by Nordic Council of Ministers. This book was released on 2013-06-19 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Statistics for Censored Environmental Data Using Minitab and R by : Dennis R. Helsel
Download or read book Statistics for Censored Environmental Data Using Minitab and R written by Dennis R. Helsel and published by John Wiley & Sons. This book was released on 2012-02-01 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Praise for the First Edition " . . . an excellent addition to an upper-level undergraduate course on environmental statistics, and . . . a 'must-have' desk reference for environmental practitioners dealing with censored datasets." —Vadose Zone Journal Statistics for Censored Environmental Data Using Minitab® and R, Second Edition introduces and explains methods for analyzing and interpreting censored data in the environmental sciences. Adapting survival analysis techniques from other fields, the book translates well-established methods from other disciplines into new solutions for environmental studies. This new edition applies methods of survival analysis, including methods for interval-censored data to the interpretation of low-level contaminants in environmental sciences and occupational health. Now incorporating the freely available R software as well as Minitab® into the discussed analyses, the book features newly developed and updated material including: A new chapter on multivariate methods for censored data Use of interval-censored methods for treating true nondetects as lower than and separate from values between the detection and quantitation limits ("remarked data") A section on summing data with nondetects A newly written introduction that discusses invasive data, showing why substitution methods fail Expanded coverage of graphical methods for censored data The author writes in a style that focuses on applications rather than derivations, with chapters organized by key objectives such as computing intervals, comparing groups, and correlation. Examples accompany each procedure, utilizing real-world data that can be analyzed using the Minitab® and R software macros available on the book's related website, and extensive references direct readers to authoritative literature from the environmental sciences. Statistics for Censored Environmental Data Using Minitab® and R, Second Edition is an excellent book for courses on environmental statistics at the upper-undergraduate and graduate levels. The book also serves as a valuable reference for??environmental professionals, biologists, and ecologists who focus on the water sciences, air quality, and soil science.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems.
