This book was released on 2009-01-29 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with many aspects of the physical and chemical limnology of the Salton Sea, California’s largest lake and a lake that may soon to be the object of a multi-billion dollar restoration project. Formed in 1905 by an accidental breaching of outtake structures on the Colorado River, and maintained since then by large and steady inflows of agricultural wastewaters, it has long served as an important habitat for fish and waterbirds and as a major recreational area for people. Highlly eutrophic and with a salinity that is steadily rising and now nearly 50 g/L, it is a lake in great trouble. Most fish species have disappeared, and large fish and bird dieoffs have been common in recent decades. Many of the papers in this volume represent studies undertaken with the aim of informing the re-engineering of this ecosystem so that its value to wildlife and man can be restored or enhanced.

Download or read book Ecotoxicology and Temporal Trends of Arsenic and Selenium in a Saline and Eutrophic Lake in California written by Marie Françoise Moreau and published by . This book was released on 2007 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Salton Sea, the largest lake in California, receives the vast majority of its inflows from agricultural and municipal wastewaters released from increasing activities in its watershed. This saline and eutrophic lake is, nonetheless, extremely valuable as wildlife habitat and for recreational activities, therefore the impacts of contaminants on this ecosystem and human health have been of concern for decades. To address this concern, we: (1) evaluated human and wildlife toxicological risks based on contaminant concentrations measured in tilapia (Oreochromis mossambicus) and proposed safe consumption limits for anglers; (2) extended this evaluation to two other abundant fish species present in the lake, namely bairdiella (Bairdiella icistia) and orangemouth corvina (Cynoscion xanthulus); (3) assessed the long-term temporal changes in selenium and arsenic concentration in fish fillet from the Salton Sea and proposed a plausible biogeochemical cycle for both elements in order to explain these changes. Both Se and inorganic As concentrations were found to be elevated enough to be of potential concern for the health of anglers. With regards to the potential impact on fish and piscivorous birds, we could not conclude whether concentrations of As pose a threat to the fish and piscivorous birds. Se concentrations could be elevated enough to negatively affect fish health, reproduction and immune systems of piscivorous birds, but definitive studies are lacking. A General Linear Model (GLM) was constructed to test whether As and Se levels changed over the last twenty years in fish from the lake. The model revealed that Se concentrations decline significantly at an overall annual rate of 3.9 percent while As concentrations increased significantly at an estimated annual rate of 11.7 percent. Finally, we presented a set of mechanisms to explain the changes in As and Se concentrations within the lake. We conjectured that rising salinity and anthropogenic eutrophication of the lake have resulted in an increase in frequency of anoxic events in this polymictic lake, consequently favoring the development of conditions conducive to the precipitation of Se into and concomitant release of As from the sediments, thus influencing the bioavailability and bioaccumulation of the trace elements.
