Assessment Water Quality and Seasonal Variations Based on Aquatic Biodiversity of Sundarbans Mangrove Forest, Bangladesh

Author(s): Md. Nazim Uddin, Md. Shamim Reza, Nasimul Jamil AHM

This study examines the seasonal variation and asses surface water quality of Sundarbans Mangrove Forest in Bangladesh. The statistical analysis ANOVA was used to explore the seasonal variations among three seasons. Water quality and seasonal variation were assessing by measured twelve physico-chemical parameters like Temperature, EC (Electrical Conductivity), pH, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Salinity, Total Alkalinity, Total Acidity, Free dissolved CO2, Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD) and Chemical Oxygen demand (COD).  The values most of the water quality parameters indicate that the sundarbans aquatic habitat is at suitable range for aquatic species but have a little concern about Salinity values. During study time low level of BOD and COD value indicates that the organic waste pollution was insignificant in the Sundarbans water. The statistical analysis ANOVA shows a significant seasonal variation among three seasons at 0.01 levels of significance.
