ASSESSMENT ON THE WATER ALITY AT THE MOTH OF PATHEIN RIVER AYEYARWADY REGION MYANMAR
Abstract
- The aim of this paper is to assess the water quality of Patheinriver around the river mouth and to evaluate the pollution loading and water quality criteria of Pathein river. In this paper, a total of 9 river water samples were collected near Payala Village in hot, rainy and cold seasons of the year 2014. Sampling sites were recorded with GPS detector. Some physicochemical properties (pH, DO, TSS, turbidity, chlorinity, salinity, total alkalinity, total hardness, BOD and COD)and nutrient levels (orthophosphate, organic phosphate, total phosphate, total nitrogen and chlorophyll a) were determined. Trace metals (As, Cd, Pb, Hg, Fe, n, Cr, Mn and Cu) concentrations of the river water samples were determined. (Based on DO (7.16-7.39 ppm),orthophosphate (0.15-0.24ppm) and total nitrogen(1.12-1.56 ppm) values, the river water near Payala village could be identified as low and medium nutrient enrichment, i.e., oligotrophic in hot season and mesotrophic in rainy and cold seasons.)
