Download or read book Physical and Chemical Aspects of the Distribution of Polychlorinated Biphenyls in the Aquatic Environment written by RN. Dexter and published by . This book was released on 1979 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of polychlorinated biphenyl (PCB) compounds in Puget Sound is discussed in terms of the physical and chemical processes that influence their flow throughout the estuary. These data were used to examine the accumulation of PCBs in suspended phases and in lower trophic level biota. At the low PCB levels detected in this region, the data suggest that accumulation is predominantly governed by an equilibrium-partitioning mechanism. Support for the applicability of partitioning constants is presented, together with a discussion of their utility in describing the general distribution of PCBs in the aquatic environment.

Available in PDF, EPUB and Kindle. Book excerpt: The origins of this volume date back to the 1978 American Society of Limnology and Oceanography (ASLO) meetings in Victoria, British Columbia. Interest in the ecology of mysids, particularly Mysis relieta. was growing rapidly, so a meeting of active workers was held at the ASLO conference. Although the small group of researchers attending that first meeting were primarily North American and interested in Mysis relieta. the group quickly expanded to include researchers from every continent with interests in all aspects of mysid biology (see Appendix). The group, informally called the Mysid Research Group, formed to serve two basic functions·. The first was to facilitate communication among mysid researchers by publishing a member ship list and periodic newsletters. The second was to organize an international symposium on mysid ecology. After several false starts, a symposium was successfully held in conjunction with the 1981 ASLO meetings in Milwaukee, Wisconsin. The symposium lasted over parts of two days with an evening workshop the second day. Altogether, 1 poster and 21 oral presentations were given by 42 researchers. This volume is an outgrowth of that symposium and includes 15 of the papers originally presented at the conference. In order to make the volume as comprehensive as possible, contributions from individuals who could not attend the symposium were solicited. Thus, a total of 22 original contributions make up the present work.

Available in PDF, EPUB and Kindle. Book excerpt: Need-to-know information on the classification and identification of aquatic invertebrates. standard reference used by generations of professionals and students is the source for authoritative information on the natural history, ecology, and taxonomy of free-living American freshwater invertebrates. Completely revised and updated, this professional field guide features a wealth of new knowledge on invertebrate animal phyla covered in the previous edition as well as fully modified sections on the preparation of materials. Other important features of Pennak's Freshwater Invertebrates of the United States, Fourth Edition include: * Current taxonomical arrangements of all freshwater invertebrate animals, excluding insects * Improved graphical treatments and keys to identification, several provided by specialists * Photographs and color plates to aid identification * More than 300 line drawings, many new to this edition * Taxonomic keys carried uniformly to genus level in all but two phyla, with frequent references to species.

Download or read book Plant Response to Air Pollution written by Mohammed Yunus and published by John Wiley & Sons. This book was released on 1996-09-10 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air pollution poses a serious threat to human health and the environment worldwide. It contributes significantly to regional and global atmospheric issues such as global warming, acidification and depletion of the ozone layer. It affects every living thing, including all kinds of vegetation on which we depend for our survival. Although several works have appeared on air pollution, few, are able to provide the broad background that encompasses the whole gamut of plant responses to atmospheric insult. This multi-authored work integrates the varied plant growth responses to the pollution stress; the focus of the attention is plant rather than pollutant. This portrays a clearer picture of plant performance versus air pollution, and helps develop a better insight of the pollution-based disturbances at the different levels of plant life. The book shall interest both students and researchers of environmental botany and forestry as well as all those who love plants and have any interest towards global vegetation and environmental health.
