Green Algae: Bioindicator of Water Quality in the Rivers, Neyshabur, Iran

In recent years, as water scarcity has been exacerbated, the focus on water resources management has been twofold. The optimal use of fresh water resources in each country requires the development of appropriate methods for monitoring and maintaining water quality. Industrial and agricultural activities are the main commercial activities that endanger the health of water resources due to the release of hazardous wastewater. Considering the limitations of common methods applied to assess the amount of water contamination, development of alternative approaches to measure the physicochemical properties of water has always been considered. Paying attention to the potential of algae communities in declaration of the level of pollution in water resources, they can be served as suitable biological indicators. In the present study, the release of garden wastewater to the river of Bojan village from the city of Neyshabur was carefully investigated. Effects of excessive nutrient supplementation such as Sequesterene resulted in 7-fold increase in the concentration of Fe+2 ion in comparison with the Control.It were significantly correlated with the changes in algal communities and their frequency of observation. The results of this study showed that the use of algal species as a suitable biochemical indicator could be useful for investigation the presence and concentration of pollutants such nutrients and iron ion, in particular. The results of this research could be used in better recommendations for gardening and more accurate management of wastewater entering the riverside.
