      Rhodamine B and Rhodamine WT are fluorescent dyes commonly used as tracers in hydrological investigations. Since introducing intensely red substances into rivers raises understandable doubts of ecological nature, the authors aimed at examining the influence of these dyes on small water fauna using bioindication methods.

Fluorometric analysis, or fluorometry, uses the physical phenomenon called fluorescence. Be- cause fluorescence is the outstanding property of all tracer dyes, a general understanding of the phenomenon is necessary to assure its proper use in any application of dye Size: 4MB.

Preface. The series of manuals on techniques describes procedures for planning and executing specialized work in water-resources investigations.

The material is grouped under major subject headings called books and further subdivided into sections and chapters; Section A of Book 3 is on surface-water techniques. The unit of publication, the chapter.

Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus.

The advantages of dye tracing are (1) low detection and measurement limits and (2) simplicity and accuracy in measuring dye tracer concentrations using fluorometric techniques. The manual contains necessary background information about fluorescence, dyes, and fluorometers and a description of fluorometric operation and calibration procedures as a guide for laboratory and field use.

Available in the National Library of Australia collection. Author: Wilson, James F. (James Franklin), ; Format: Book, Microform; 1 v.: ill. ; 28 cm. This manual describes fluorometric procedures used by the U.S.

Geological Survey in dye tracer studies to measure time of travel, dispersion, reaeration, and dilution-type discharge. The outstanding characteristics of dye tracing are (1) its low detection and measurement limits. The versatility of dye tracing is illustrated by examples of several other applications, including streamflow measurements, estuarine dispersion studies, herbicide tracing, and ground-water studies.

Many different substances have been used as tracers in hydrology. Some are File Size: KB. The procedures contained in this document are to be used when measuring dye tracer of various, aqueous phase environmental media in the field or on samples returned to the laboratory.
