Assessment of water quality in terms of physico-chemical parameters of Bhitarkanika mangrove system, Odisha, India

Abstract: 

The present study is aimed at assessing the physico chemical characteristics of water samples collected from the mangrove forest in Bhitarkanika. Mangrove forest is a component of wetlands that has been recognized as one of the most productive ecosystems. Physico-chemical analysis of water samples of Bhitarkanika mangrove forest, Odisha, India, was studied for a period of one year during January 2013 to December-2013. Atmospheric and surface water temperatures (◦C) varied from 19◦C to 33◦C and 22◦C to 29◦C respectively. Seasonal variations of different physico-chemical parameters investigated were as follows: pH (6.70 to 8.40), dissolved oxygen (3.25 to 8.58mg/l), biological oxygen demand (0 to 20.0 mg/l), electrical conductivity (56 to 290 μmho/cm), potassium (0.18 to 6.32 mg/l), calcium (2.32 to 48.24 mg/l), magnesium (0.82 to 119.5mg/l), sodium (4.32 to 342.06mg/l), bicarbonate (7.32 to 60.24mg/l), carbonate (BDL), chloride (4.64 to 362.40mg/l), sodium absorption ratio (0.62 to 842mg/l). A seasonal variation of these parameters was observed throughout the  study period  and  monthly comparisons were  made  as  monsoon, pre-monsoon and  post- monsoon.
