Continuous Monitoring Of Volatile Organic Compounds In Air Emission Using Membrane Extraction Microtrap Gc System, Xin Zhang

Theses

A novel method for continuous monitoring volatile organic compounds (VOCs) in air at trace level is presented. A membrane module and a microtrap were used along with gas chromatographic analysis. The membrane module consisted of a bundle of silicone rubber hollow fibers and separated the VOCs from the gaseous stream. The microtrap which is a very small adsorbent trap played the roles of preconcentrator and injector. The VOCs selectively permeate across the membrane into a strip gas in the membrane module. Before entering the GC column, the VOCs are trapped and concentrated by the microtrap. Desorption of the VOCs is …

Determining Recreational Visitor Carrying Capacity: The Case Of Black Canyon At Lake Mead National Recreation Area, Kenneth C. Forman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lake Mead and Lake Mohave, created by Hoover and Davis Dams respectively, were combined, along with much of the surrounding area, into the Lake Mead National Recreation Area in 1964. The enabling legislation is specific about the duty the National Park Service has to the public to create and maintain this, and other, national recreation areas for the benefit of the visitors, the environment, and future generations. By investigating human impacts on the physical environment (water quality, litter, etc.) and by querying park users on their opinions (with respect to crowding, visitor behavior, etc.), insight can be gained about appropriate …

Use Of Riparian Vegetated Filter Strips To Reduce Nitrate And Fecal Contamination In Surface Water, Mark S. Coyne, Robert L. Blevins, Rebecca A. Gilfillen

KWRRI Research Reports

This research assessed fecal bacteria trapping in surface runoff by grass filters and their potential to enhance NO₃^- removal via denitrification. Grass filter strips 9.0 m long trapped over 99% of the soil in surface runoff in 1992. Fecal coliform removal was less than 75%. In 1993, 9.0 and 4.5 m grass filter strips trapped 99 and 95% of the sediment, respectively. Fecal coliform trapping efficiency was 90% in 9.0 m grass filters and 75% in 4.5 m filters. Fecal streptococci trapping efficiency was 77% in 9.0 m grass filters and only 56% in 4.5 m filters. Fecal …

Conference organizers and/or session moderators included University of Colorado School of Law professors David H. Getches, Judith Jacobsen, Lawrence J. MacDonnell, Teresa Rice and Charles F. Wilkinson.

Shifting policy objectives and management approaches for the public lands of the West are provoking heated debate about how these decisions should be made and implemented. Are these policy directions a reflection of the "New West" or are they, in fact, a declaration of "war on the West"? Somewhere between these polarities of view, efforts are underway to open dialogue and reach consensus.

This second annual western lands conference will explore federal initiatives …
