Abstract
- The Halda River is one of the most important natural breeding ground of carp fishes in South Asia as well as Bangladesh. The study was carried out to analyze the physico-chemical parameters of the effluent discharged by the Asian Paper Mill & the physico-chemical changes in the water of Halda River with the addition of waste water from the Asian Paper Mill. Water samples from the freshwater resources were collected from different points and tide conditions and at different seasons for continuous monitoring during 2011. The data analyzed in different methods were followed during the study period like Argentometric Methods (APHA, 1976) for Chloride determination, Standard Methods (APHA, 1976), Spechtophotometric methods for Nitrate and Phosphate determination, Winkler methods for Dissolved Oxygen analyzed. SPSS software was used for data analysis. Test of Significance (ANOVA) also done for statistical data analysis. The collected samples were analyzed for the following parameters: temperature, total suspended solids (TSS), total solids (TS), total dissolved solids (TDS), turbidity, pH, total alkalinity, chloride, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), nitrate-N, Phosphate-P. The mean values of parameters were Air temp.- 26.83 0C, Water temp.- 25.67 0C, TSS- 3.37 mg/L , TS- 837.95 mg/L , TDS -835 mg/L, Turbidity - 7.42 cm, Soil P H -7.72, Water P H -8.13, Alkalinity - 140.25 mg/L, Chloride -43.53 mg/L, DO- 2.55 mg/L, BOD5 - 277.42 mg/L, COD - 1077 mg/L, NO - - 0.19µgm/L, PO - - 0.08 µgm/L. The finding results shows the high values of T.S, T.D.S, D.O, B.O.D, C.O.D, Nitrate, Phosphate which is quite high with standards value for industrial effluent (EQS, 1991) for Bangladesh. The data showed the water quality slightly differs in monsoon and post-monsoon than winter season. Apart from destroying the quality of water, these hazardous chemicals from paper mills cause irreparable damage to the aquatic flora and fauna. Steps must be taken to save the Halda River from getting polluted from the industrial effluent
