This book was released on 2013-07 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Government Printing Office (GPO) was created in June 1860, and is an agency of the the U.S. federal government based in Washington D.C. The office prints documents produced by and for the federal government, including Congress, the Supreme Court, the Executive Office of the President and other executive departments, and independent agencies. The Coastal Zone Information Center (CZIC) collection provides access to nearly 5,000 coastal related documents that the U.S. Government Printing Office (GPO) received from the National Oceanic and Atmospheric Administration (NOAA) Central Library. The collection provides almost 30 years of data and information crucial to the understanding of U.S. coastal management and NOAA's mission to sustain healthy coasts. This is one of their documents.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuaries are complex ecosystems that are composed of a number of sensitive and inter-dependent environments. An abundance of nutrients combine with the dynamic conditions to create some of the most productive environments on the planet. Almost 85% of the commercially harvested fish in the United States depend on estuaries and the surrounding coastal waters at some stage in their life history. Many estuarine drainage basins contain large quantities of agricultural acreage. Over 29 million pounds of active ingredient of pesticides are applied in coastal drainage basins in the United States each year. Studies have shown that the overall condition of the nation's estuaries is fair, while benthic condition is poor. Seventy five percent of estuarine sediments are contaminated with pesticides. Concentrations of pesticides in 30% of the estuaries exceed the levels that are known to result in ecological effects at least 10% of the time. There have been few comprehensive pesticide studies in estuaries to date. The Albemarle-Pamlico (A-P) Drainage Basin of North Carolina forms the second largest estuarine system in the United States and supports heavy agricultural production with high pesticide use. I evaluated measurement and modeling strategies to assess exposure in the A-P drainage basin. Atrazine and metolachlor were the most frequently detected pesticides in water samples that were collected in the A-P drainage basin in 2000 and 2001. Concentrations of these compounds exceeded both human health and aquatic life criteria in 2000. No toxicity thresholds were exceeded in samples collected in 2001. Due to the expense associated with field sampling and pesticide analysis alternative methods for estimating pesticide exposure have been developed, including fate models. The Exposure Analysis Modeling System (EXAMS) was modified to model the fate of pesticides, specifically atrazine and metolachlor, in a small tidal estuary of the larger A-P estuarine system. Based on the estimat.

Available in PDF, EPUB and Kindle. Book excerpt: The coastal tropics comprise some of the most sensitive and yet the most understudied ecosystems in the world. Coastal plains and river valleys are also home to agriculture on a vast scale, and it is not surprising to find that streams and rivers receive the majority of agricultural runoff, carrying the residues of insecticides, fungicides and othe
