This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polybrominated diphenyl ethers (PBDEs) have been and are still extensively used as flame retardants in a wide variety of consumer products including plastics, textiles, furniture, and electronic circuitry. The prevalence of PBDEs in the Great Lakes and associated wildlife is virtually unknown, although recent studies have shown that concentrations of PBDEs in Lake Michigan salmonids to be among the highest in the world. PBDEs have also been detected in the eggs and tissue of fish-eating birds. Because of evidence that suggests PBDEs may bioaccumulate, there is concern about potential adverse affects in both humans and wildlife. Double-crested cormorants (Phalacrocorax auritus) are piscivorous and an upper level food chain species, therefore monitoring their eggs should be a useful environmental indicator. In 2003, eggs from double-crested cormorants were collected from islands in Lake Michigan, the Bay of Green Bay, Lake Superior and an inland site in central Wisconsin and analyzed for PBDEs. Total PBDE concentrations ranged from below the limit of detection to 891 ng/g (wet wt.). The highest concentrations were found in eggs collected from Cat Island in Green Bay and the lowest concentrations in eggs from an inland site in central Wisconsin (Mead Wildlife Area). A pattern involving the bioacumulation of PBDE congeners was evident with similar composition in all samples. Congeners composition consisted of BDE-100 (33.0%), BDE-47 (30.9%), BDE-99 (17.4%), BDE-153 (10.6%) and BDE-154 (8.1%). Results indicate that eggs from the inland site had significantly lower concentrations of PBDEs than eggs collected from Lake Michigan and Green Bay (p = 0.002). PBDE concentrations in eggs collected from Spider Island (Lake Michigan) in 1988 were significantly lower than PBDE concentrations from eggs collected at the same site in 1994 (p = 0.001). However, the concentration in eggs from 1994 were not significantly different than the concentration in eggs collected in 2003 (p = 0.24).

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.

Agricultural runoff, urban waste, industrial discharge, landfill leachate, and atmospheric deposition, are all to blame. Contamination of the various ecosystems is reviewed, and what is known about the effects of this pollution. This volume provides an invaluable resource for those in environmental research, measurements, and decision making concerning the Great Lakes.

Download or read book Applications of Mass Spectrometry in Life Safety written by Crisan Popescu and published by Springer Science & Business Media. This book was released on 2008-09-02 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass spectrometry (MS) along with its hyphenated techniques is capable of high throughput, sensitivity, accuracy and selectivity for the analysis of structure and composition of almost any product. Like in electrophoresis, MS separates mo- cules based on the mass-to-charge ratio. In case of gel electrophoresis (SDS- PAGE), a well-known and efficient bioanalytical technique, proteins bear negative charges but have the same charge density, so proteins are separated according to their size. Similarly, in case of MS analysis, proteins carry the same charge, and are separated by their molecular weight. Unlike SDS-PAGE, however, modern ultra high resolution MS discerns very small mass differences and can resolve and completely identify in a single experiment species of the same nominal mass in complex biological mixtures. Consequently, MS can be used for the structural characterization, identification and sensitive detection of mixtures of biomolecules or for assessing the quality of isolated proteins (purity, integrity, or post-translational modifications, for example), carbohydrates, nucleic acids, drugs, metabolites, pollutants etc. In the post-genome era, MS is continuously developing as one of the most re- able analytical method for elucidating the structure of molecules originating from various biological matrices. The potential of MS for high-sensitive structural a- lyses became unsurpassable after the introduction of electrospray (ESI) and matrix assisted laser/desorption ionization (MALDI) methods, on one hand, and the pos- bility to deduce in detail unknown biopolymer structures by highly accurate mo- cular mass measurement followed by sequencing using dissociation techniques based on multiple stage MS, on the other.

Download or read book Chemical Biomarkers in Aquatic Ecosystems written by Thomas S. Bianchi and published by Princeton University Press. This book was released on 2011-02-28 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a unique and thorough look at the application of chemical biomarkers to aquatic ecosystems. Defining a chemical biomarker as a compound that can be linked to particular sources of organic matter identified in the sediment record, the book indicates that the application of these biomarkers for an understanding of aquatic ecosystems consists of a biogeochemical approach that has been quite successful but underused. This book offers a wide-ranging guide to the broad diversity of these chemical biomarkers, is the first to be structured around the compounds themselves, and examines them in a connected and comprehensive way. This timely book is appropriate for advanced undergraduate and graduate students seeking training in this area; researchers in biochemistry, organic geochemistry, and biogeochemistry; researchers working on aspects of organic cycling in aquatic ecosystems; and paleoceanographers, petroleum geologists, and ecologists. Provides a guide to the broad diversity of chemical biomarkers in aquatic environments The first textbook to be structured around the compounds themselves Describes the structure, biochemical synthesis, analysis, and reactivity of each class of biomarkers Offers a selection of relevant applications to aquatic systems, including lakes, rivers, estuaries, oceans, and paleoenvironments Demonstrates the utility of using organic molecules as tracers of processes occurring in aquatic ecosystems, both modern and ancient
