Physicochemical and biological status of Aghlagan river, Iran: Effects of seasonal changes and point source pollution

Although the macroinvertebrates have been widely used as bio-indicator for river water quality assessment in developed countries, its application is new in Iran and data on the health status of the most ecologically important rivers in Iran is scarce. The present study aimed at monitoring and assess...
