Description

Algae and bacteria form the base of the aquatic food chain, and disturbances affecting these organisms have ripple effects up the food chain. Many dyes used in the textile industry are water soluble, difficult to remove from effluent, and enter river systems intact. Although many studies have been undertaken to determine the best ways to remove dyes from textile effluent, few studies have identified the detrimental effects of these dyes once they reach the waterway. This study utilized substance diffusing substrata to identify the effects of textile dyes on algae and bacteria communities, using changes in dissolved oxygen concentrations as a proxy for production and respiration.
