Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

Download or read book Ecology of the Southern California Bight written by Murray D. Dailey and published by Univ of California Press. This book was released on 1993 with total page 952 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here is a benchmark study of one significant stretch of the Pacific Ocean, the Southern California Bight. Extending from Point Conception to the Mexican border and out to the 200-mile limit, these waters have never before been investigated in such detail, from so many points of view, by such an eminent group of scientists. The twenty-five expert contributors summarize everything known about the physical, chemical, geological, and biological characteristics of the area in individual chapters; the volume concludes with a synthesis of the information presented. In addition, chapters are devoted to the influence of humans on the marine environment and to the various laws and governmental agencies concerned with protecting it. Because Southern California is so heavily populated and because the ocean is a major recreational area for its people, the information in this unique volume will be invaluable for the region's planners and decisionmakers as well as for all those who study the globe's marine resources and ecology.

Download or read book Climate change Unpacking the burden on food safety written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-03-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is causing unprecedented damage to our ecosystem. Increasing temperatures, ocean warming and acidification, severe droughts, wildfires, altered precipitation patterns, melting glaciers, rising sea levels and amplification of extreme weather events have direct implications for our food systems. While the impacts of such environmental factors on food security are well known, the effects on food safety receive less attention. The purpose of Climate change: Unpacking the burden on food safety is to identify and attempt to quantify some current and anticipated food safety issues that are associated with climate change. The food safety hazards considered in the publication are foodborne pathogens and parasites, harmful algal blooms, pesticides, mycotoxins and heavy metals with emphasis on methylmercury. There is also, a dedicated section on the benefits of forward-looking approaches such as horizon scanning and foresight, which will not only aid in anticipating future challenges in a shifting global food safety landscape, but also help build resilient food systems that can be continually updated as more knowledge is assimilated. By building a more widespread and better understanding of the consequences climate change has on food safety, it is hoped that this document will aid in fostering stronger international cooperation in making our food safer by reducing the global burden of these concerns.

Download or read book Pollution of Water Bodies in Latin America written by Leobardo Manuel Gómez-Oliván and published by Springer. This book was released on 2019-11-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.
