Effect of pollution of dissolved oxygen concentration in seer stream of Shivalik Himalayas

This paper addresses the effect of pollution on dissolved oxygen content (DO) in a Shivalik Himalayan stream during early hours of day in the summer season (May 2009-June 2010). The study showed that the dissolved oxygen in the stream is below 4 mg/L in a stretch of 2600 m and, therefore, water is not fit for public supply, bathing, wildlife and fish culture.
