Book Synopsis The Role of the Ocean in Global Cycling of Persistent Organic Contaminants by : Irene Stemmler
Download or read book The Role of the Ocean in Global Cycling of Persistent Organic Contaminants written by Irene Stemmler and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Persistent organic contaminants, which are bioaccumulative and toxic are a concern for the ecosystems and human health and are regulated under international law (global and regional conventions, besides other). If semivolatile, they cycle in different environmental compartments and follow complex transport pathways. The ocean is believed to play a key role in the cycling by accumulating and storing the contaminant and providing a transport medium. But substance fate in the marine environment is not fully understood yet. Here, the global multicompartment chemistry-transport model MPI-MCTM is used to study the fate of organic pollutants in the marine and total environment. For the first time historical emission data are used in spatially-resolved long-term simulations of an insecticide, DDT, and an industrial chemical, perfluorooctanoic acid (PFOA). The model results give new insights into the cycling of these substances as different spatial and process resolutions were tested. E.g. for DDT the model results show saturation and reversal of air-sea exchange, which was not indicated by any other study before.

Download or read book Persistent Organic Pollutants in the Ecosystems of the North Pacific written by Vasiliy Tsygankov and published by Springer Nature. This book was released on 2023-10-30 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book reports the results on the fate of POPs in the abiotic and biotic components of the aquatic environment North Pacific Ocean (include Russian part of North Pacific), possible health risks for coastal residents Pacific Ocean exposed to these hazardous pollutants are systematized. In particular, indicator organisms (fish, birds, and mammals), indicating the pollution of the region, were identified; the possible ways of xenobiotic transfer from the sea to the land are shown; the targets of POPs impact on living organisms were determined; the time of circulation of pollutants in the biosphere was determined; a list of “priority” toxicants for the region based on quality screening was compiled; the risks to human health from the consumption of contaminated aquatic organisms were assessed; the levels of POPs in the human body were measured. The book is interesting for specialists in the agro-industrial complex, aquaculture and medicine, teachers and graduate students of universities, researchers, which interested in the problems of persistent organic pollutants (POPs). There are no similar books on the study of POPs in the Russian part of the Pacific Ocean in the world literature. This book is useful to scientists of the world who study the fate of POPs.

Book Synopsis Characterizing the Origin and Long-range Transport Behavior of Persistent Organic Pollutants in the North American Atmospheric Environment Using Passive Samplers [microform] by : Li Shen
Download or read book Characterizing the Origin and Long-range Transport Behavior of Persistent Organic Pollutants in the North American Atmospheric Environment Using Passive Samplers [microform] written by Li Shen and published by Library and Archives Canada = Bibliothèque et Archives Canada. This book was released on 2004 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Monitoring is recognized as an essential tool for identifying status and spatial and temporal trends of persistent organic pollutant (POPs) in the atmosphere. To investigate the origin and long-range transport behavior of POPs in air, a novel passive air sampler (PAS) was developed based on the polystyrene/divinylbenzene co-polymeric resin XAD. The PAS was characterized by sorption measurements of chlorobenzenes onto XAD at various temperatures, wind tunnel experiments and computer simulations of the uptake kinetics, and field calibration experiments under Arctic and temperate conditions. The performance of this PAS was evaluated by comparing PAS-derived concentrations with those measured by conventional HiVol samplers. These studies demonstrated the usefulness of XAD-based PAS for atmospheric POP monitoring. A PAS network was established across North America, consisting of 40 stations covering 72 degrees of latitude (10° to 82°N) from the Arctic to Costa Rica and 72 degrees of longitude (53° to 125°W) from Newfoundland to Vancouver Island. Four of these stations constituted an altitudinal transect in the southern Canadian Rocky Mountains, covering an elevational range of more than 1500m. Annually averaged air concentrations of organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) were determined in 2000/2001 at these stations, as was the enantiomeric composition of chiral OCPs. The distribution patterns of the POPs were found to depend on their physical-chemical properties, their emission history, and the environmental conditions. Evidence for global fractionation along latitude and altitude was observed. Multivariate statistical analysis allowed for a better understanding of the observed composition patterns of PCBs and PBDEs. Estimation of the long range transport potential of OCPs, empirically from network concentrations, and theoretically from model calculations yielded a comparable classification. In order to have consistent input data for these model simulations, a complete set of partitioning properties (aqueous solubility, octanol-water partition coefficient, vapor pressure, Henry's law constant, octanol-air partition coefficient) for fourteen OCPs was derived by compiling, evaluating, selecting, and adjusting all measured values reported in the literature. Large scale PAS networks are suitable for monitoring compliance with, and effectiveness of, regulatory control measures, and for establishing experimentally the atmospheric long-range transport behavior of POPs.

Download or read book Quantification and Modelling of Fluxes of Persistent Organic Pollutants (POPs) to Antarctic Marine Benthic Organisms written by and published by . This book was released on 2020 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine benthic ecosystems are considered to be the final sink of persistent organic pollutants (POPs). Antarctica is a global net receptor of POPs, therefore, quantification of fluxes of POPs to and in the Antarctic benthic ecosystems, although practically difficult, is essential to understand the overall dynamics of these contaminants on a global scale. In order to achieve that, Antarctic benthic ecosystems were studied as an integral part of the Antarctic environment as a whole. Furthermore, robust quality assurance and reporting practices are needed to establish comprehensive time trends of these pollutants, especially due to their expected relatively low concentrations. Current thesis was one of the first attempts to assess fluxes of POPs to benthic Antarctic ecosystems. The major outcome of the study is the conformation of the hypothesis on potentially increasing concentrations of POPs in the benthic ecosystems. Simultaneously, the concentrations of POPs in the pelagic ecosystems may have also stopped decreasing, which was previously indicated. Nevertheless, the fluxes of POPs and, possibly, their toxicological effects on the Antarctic benthic animals will undergo considerable changes in the future due to global change, which must be researched further in detail.

Available in PDF, EPUB and Kindle. Book excerpt: Recently there has been a global concern on Persistent organic pollutants due to its negative effects on environment and human health. Despite this, very little scientific data exists from small island developing states (SIDs). Project POPS is about an investigation into a toxic cocktail of POPs chemicals that poses a threat to human population and our environment. This book looks specifically into chemicals that are present in Fiji s abiotic environment. A number of chemical culprits that are not produced in Fiji or the Pacific Region are identified by their concentration, toxicity and presence in various land-use areas where they reside. Monitoring POPs in Fiji s abiotic environment reveals possible illegal use of pesticides, unknown sources for dioxins and brominated compounds that are used as fire retardants or used in upholstery. Further, provides information regarding contamination by long range atmospheric transport. This book, therefore, provides an insight into POPs situation in SIDs. The findings should help shed some light on future monitoring of POPs in SIDs and is particularly useful to professionals in the scientific community.
