Book Synopsis Selected Heavy Metals in Sediments and Biota from Desert Streams of the Gila River Drainage (Arizona) by : MA. Lewis

This book was released on 1980 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution and bioaccumulation of heavy metals in mine-polluted and nonpolluted desert streams was studied during 1975 and 1976. Heavy metal concentrations in reference streams were less than the detection limits; however, periodic input of mining and milling wastes increased the zinc, copper, manganese, and iron in receiving test streams to above this level. Copper and, to a lesser extent, managanese concentrations were higher in samples of sediment and biota collected from contaminated waters (P 0.05). The copper concentration was twelve times higher in biota collected from metal-contaminated waters than an identical species collected from reference areas. Fish viscera, fish eggs, and eviscerated fish in mine-impacted streams also contained a higher copper content. In contrast, concentrations of iron, cadmium, lead, and mercury were similar in all samples. The distributions of copper, manganese, and iron in the trophic levels were similar; consumer organisms concentrated less metal than did the sediments of primary producers. An exception was zinc, which achieved its highest concentration in the middle trophic levels. Higher copper levels in fish tissue did not effect length-weight relationships or condition values (P 0.05).

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This chapter shows the results of the determination of the levels of Copper (Cu), Iron (Fe), Magnesium (Mg), Manganese (Mn), and Cadmium (Cd) in sediments of the ,ÄúPalizada River,Äù; evaluated by atomic absorption. The results show high levels of Fe, Mg, and Mn concerning previous studies and are directly related to agricultural and livestock activities in the area. The metal-metal correlation analysis show significant values, suggesting that the generation source is the same. Some of the pollutants produced by industrial or population centers; end up in natural water bodies; by different physical processes, such as precipitation, complex formation, and others. These contaminants can bioaccumulate in aquatic organisms and reach humans through the food chain. Certain heavy metals such as cadmium (Cd) produced by human activities have been found in the oceans and the tissues of different organisms; which constitutes a risk for consumption; Cd is classified as an element that predisposes to the presence of Cancer. Therefore, the study of sediments is fundamental for determining the degree of contamination of an ecosystem.

Book excerpt: This study evaluated the use of statistical randomization tests in data analysis regarding heavy metals content in sediments from the Caí River basin (Brazil). During one year, four samplings took place at eleven sites in the Caí River and tributaries. The results showed significant differences between some locations, enabling spatial segregation of sites affected by natural and anthropic sources. Considering a significance level (?) of 5%, the control station, above polluted areas, showed the best quality; Caí River station after the mouth of Pinhal/Belo stream indicated influence from the industrial complex of Caxias do Sul region, as well as copper compounds use in vineyards; and the Cadeia and Forromeco streams showed effects of natural contribution from basalts and surface runoff on naked soils. For ?=10%, it was possible to identify chromium pollution by tanneries in the Cadeia stream. Long-term studies should be performed, since understanding temporal aspects such as alteration processes in sediments involves a much longer time scale.

Book Synopsis Environmental Impacts of Metallic Elements by : Muhammad Aqeel Ashraf
Download or read book Environmental Impacts of Metallic Elements written by Muhammad Aqeel Ashraf and published by Springer. This book was released on 2015-01-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a combined analysis of the geochemical, physio-chemical, biological and analytical techniques to provide a better understanding of the biogeochemical cycling of heavy metals in ex-mining areas. The findings presented in this book provide a basis for evaluation of the environmental impacts of mining activities, especially tin mining. The chapters provide a general picture of the land use, geography, concentration and chemical speciation of heavy metals in mining areas. The impacts of bioavailable metal species are supported by a detailed case study on Bestari Jaya. The book concludes with remediation methods along with classical and modern approaches, their limitations and economic feasibility.

Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

Book excerpt: ‘KUMBA AFRICA’, is a compilation of African Short Stories written as fiction by Sampson Ejike Odum, nostalgically taking our memory back several thousands of years ago in Africa, reminding us about our past heritage. It digs deep into the traditional life style of the Africans of old, their beliefs, their leadership, their courage, their culture, their wars, their defeat and their victories long before the emergence of the white man on the soil of Africa. As a talented writer of rich resource and superior creativity, armed with in-depth knowledge of different cultures and traditions in Africa, the Author throws light on the rich cultural heritage of the people of Africa when civilization was yet unknown to the people. The book reminds the readers that the Africans of old kept their pride and still enjoyed their own lives. They celebrated victories when wars were won, enjoyed their New yam festivals and villages engaged themselves in seasonal wrestling contest etc; Early morning during harmattan season, they gathered firewood and made fire inside their small huts to hit up their bodies from the chilling cold of the harmattan. That was the Africa of old we will always remember. In Africa today, the story have changed. The people now enjoy civilized cultures made possible by the influence of the white man through his scientific and technological process. Yet there are some uncivilized places in Africa whose people haven’t tested or felt the impact of civilization. These people still maintain their ancient traditions and culture. In everything, we believe that days when people paraded barefooted in Africa to the swarmp to tap palm wine and fetch firewood from there farms are almost fading away. The huts are now gradually been replaced with houses built of blocks and beautiful roofs. Thanks to modern civilization. Donkeys and camels are no longer used for carrying heavy loads for merchants. They are now been replaced by heavy trucks and lorries. African traditional methods of healing are now been substituted by hospitals. In all these, I will always love and remember Africa, the home of my birth and must respect her cultures and traditions as an AFRICAN AUTHOR.
