“…Living organisms, especially aquatic life, function best in a pH range of 6.0 to 9.0. Higher alkalinity levels in surface waters will buffer acid rain and other acid wastes and prevent pH changes that are harmful to aquatic life (Kabir et al, 2020). The alkalinities of sample water for the four stations were within the range of 35 to 190 mg/L.…”

This study was conducted to determine the suitability of water quality for fisheries management in Kaptai Lake from February 2019 to January 2020. Results showed that the temperature, transparency, TDS, pH, DO, EC, alkalinity and hardness were 20.9 to 31.8°C, 17 to 303 cm, 40 to 105 mg/L, 6.82 to 7.96, 6.1 to 7.65 mg/L, 75.33 to 172.33 µS/cm, 37 to 83 mg/L and 35 to 190 mg/L, respectively. However, nutrients as NH3, NO3-, NO2-, PO43- and SO42- were 0.01 to 0.05, 0.03 to 2.21, 36 to 96, 0.01 to 0.04 and 0.3 to 1.9 mg/L, respectively. Chlorophyll a and trophic state index (TSI) were 0.70 to 2.12 µg/L and 27.43 to 37.79, respectively. Study revealed that SO42-, DO and TDS were higher than the standard of ECR. On the other hand, NH3, NO3-, NO2-, PO43-, temperature, transparency, pH, EC, total hardness, total alkalinity, Chlorophyll a and TSI were within the standard levels. Concentrations of NO3-, NO2-, PO43-, Chlorophyll a and TSI (CHL) showed no significant variation with seasons. Conversely, TDS, transparency, EC, alkalinity, hardness, and SO42- were lower in monsoon compared to pre-monsoon and post-monsoon seasons. Besides, temperature, NH3, DO and TSI (SD) were higher in monsoon season. Results concluded that the Kaptai Lake is in mesotrophic condition with TSI (CHL) less than 40, and prominently there was a positive relationship between Chlorophyll a and Trophic State Index (TSI). In this regard, major nutrients and Chlorophyll a concentration in the Kaptai Lake may have an impact on the aquatic environment.

As the population grows and the uncontrolled industrialization, urbanization rises as well, it is high time we should give proper attention to the fact of river pollution in our country which is deploying harmful impacts both on human health and environmental, aquatic ecosystem. A plethora of studies have been done on different aspects of river water pollution. In this paper a thorough discussion regarding this fact has been presented compiling a number of important studies on it. Major causes behind this pollution have been mentioned widely, like improper management of industrial and sewage effluents. However, to detect this contamination in the major rivers of Bangladesh, various studies have been done to see the physicochemical properties of the water, such as pH, turbidity, color, odor, DO, TOD, COD, TSS, EC, dissolved metal, and other chemical and bacteriological substances etc. The microorganisms within the water are the prime sources to cause different water borne diseases like Diarrhea, Cholera, Scabies and Asthma. To find out the remedies to this problem, urgent emphasis should be given on preventive measures and to take appropriate steps to halt and improve the existing pollution of the rivers. A lot of water treatment systems are being practiced throughout the world to restore the health of the rivers as well as to reuse the waste water. Though the systems are not much popular in Bangladesh, the government should facilitates the practice of them extensively and strengthen the laws against environmental pollution.

“…The Shitalakhya river ran almost parallel to the Brahmaputra and after passing by Narayanganj district, it joined the Dhaleswari river. The Shitalakhya river, an urban river of high economic importance in Bangladesh, is prominently affected by harmful elements from innumerable sources and act as a sink of pollutant [15][16][17][18].…”

Four central rivers of Bangladesh were selected for this research. The name of the rivers is Buriganga, Dhaleshwari, Shitalakshya and Meghna. The Electrical Conductivity (EC), pH, Total Dissolved Solid (TDS), and Salinity of the four river waters were evaluated. The EC values of the water of the Buriganga, Dhaleshwari, Shitalakshya and Meghna rivers were found to be 366.0, 299.2, 290.4 and 130.8 µS/cm respectively. Similarly, the pH values of 7.67, 7.38, 7.30 and 7.18 were found for the river waters of the Buriganga, Dhaleshwari, Shitalakshya and Meghna respectively. The EC and pH values were found higher for the Buriganga river water than that of the other three river waters. The TDS and salinity of the Buriganga river water were found 180 mg/l and 0.72% respectively. On the other hand, the TDS and salinity of the Meghna river water was found lower compared to the other three rivers. From this research, this is clear that the quality of the Meghna river water is much better than the river waters of the Buriganga, Dhaleshwari, and Shitalakshya. The quality of the Buriganga river water was found inferior. Dhaka city, the capital of Bangladesh, stands on the bank of the Buriganga river, and as a result a large number of unban waste goes directly to the river Buriganga. As a result, the water of Buriganga became polluted. This investigation proved that the Meghna river water quality is still much better and suitable for many applications.
