The Effect Of Azo Textile Dyes On Gross Primary Production And Community Respiration In An Artificial Environment, Theresa L. Petzoldt
The Effect Of Azo Textile Dyes On Gross Primary Production And Community Respiration In An Artificial Environment, Theresa L. Petzoldt
Honors Theses
Azo dyes are the largest category of textile dyes in production today, with over 100,000 tons of dye produced yearly in the United States. Ten to fifty percent of this dye is not fixed to the fabric during the textile production process, and is therefore discarded as effluent. Because dye waste is difficult to process in wastewater treatment facilities, it is important to understand how this waste affects aquatic systems using a whole ecosystem approach. This study used an artificial stream to model the effects of four azo dyes on benthic biofilm production and respiration. Dyes were found to have …
