Pollution characteristics and water quality in the Visakhapatnam harbour
Abstract
The impact of organic pollution on the quality of waters in the Visakhapatnam harbour has been studied over a year at 8 stations. The enrichment of nutrients in these waters enhances the eutrophication. The construction of outer harbour retards the tidal flushing resulting in a greater stagnation of these waters. The distribution pattern of phosphate and ammonia indicates the flow of pollutant rich waters at surface towards the sea during low tide
