“…A total of 50 respondents who are directly and indirectly dependent on the river for their livelihood were surveyed from the study area. (Islam et al 2015a), which are mostly similar to the present study. Yasmeen et al (2012) found that the temperature of Buriganga River water in dry season complies with standard, which was found around 21.9 to 22.4°C; whereas in wet season, it was around 31 to 33°C, exceed the standard limit (20 to 30°C) set by DoE (2016).…”

The study was conducted to explore the physicochemical parameters of water, fish diversity andfisheries resources of Korotoa River at Bogura city of Bangladesh during July 2015 to February 2016. Thewater samples were collected from five sampling stations in the Korotoa River during wet and dry seasons.The results of the study showed that temperature, EC, TDS, DO, BOD, alkalinity, acidity and total hardnessof the Karotoa River water were 25.86ºC, 297.41 ?S/cm, 98.86 mg/L, 2.17 mg/L, 2.64 mg/L, 122.05mg/L, 3.28 mg/L and 75.59 mg/L, respectively. The DO and BOD contents of the river water were foundunsuitable for fisheries when compared with the standard of DoE. A total of ten fish species under six ordersand seven families were identified during the study period. The study also revealed that the most remarkablecause of water quality degradation of the river was waste dumping (58%) followed by urbanization and riverbank erosion. The water quality degradation (46%) negatively influenced the abundance of fish species. Theresults concluded that the water quality of the river is not favorable for production of fishes and other aquaticorganisms. The study suggested that the source of water quality degradation should be closely monitoredtogether with the industrial effluent and/or domestic sewage discharge should be reduced or stopped throughthe initiatives of the local government concerned to maintain sound and healthy ecosystem of the river.

“…The mean values of temperature, pH, TDS, EC were higher but DO, BOD were lower of the present study than the Buriganga river (Hasan et al, 2009). Islam et al (2012) investigated that temperature, TDS, EC were higher but pH, DO were lower in Dhaleshwari river than present study. Alam et al (2007) found the mean values of pH, DO, BOD and COD lower in the Surma river than the present study.…”

Abstract:The pollution of river water and sediments by heavy metals has assumed serious problems due to their toxicity and accumulative behavior. The present study has been undertaken to assess the levels of heavy metals and the extent of pollution in the surface water and sediments from the Meghna river. Water and sediment samples were collected by the Standard Methods and, processed and analyzed for heavy metals using Flame Atomic Absorption Spectrophotometer (FAAS). The mean concentrations of heavy metal found in the river water were in the order of: ). Pb and Ni were found below detection limit in river water. Based on the findings, the Meghna river water can be considered as unpolluted with respect to Cd, Cr, Mn and Zn, whereas concentration of Fe was above the standard value according to recommended standard guidelines. According to Sediment Quality Guideline (USEPA, 1989), sediments were not polluted for Cd, Pb and Zn; moderately polluted for Cr and Mn and heavily polluted for Ni. The sediment geo-accumulation index (I geo ) values showed no pollution for most of sampling sites for all studied heavy metals. Pollution Load Index (PLI) values showed that all the studied sampling sites were not polluted and on the other hand mean Contamination Factor (CF) values showed low pollution for all measured heavy metals except Ni which indicated moderate pollution. This study can be used as reference to monitor the quality of water and sediments of the Meghna river.

“…Islam et al [23] found DO ranged from 4.9 to 9.0, 4.1 to 9.8 and 5.7 to 7.3 mg/l respectively in monsoon, post-monsoon and pre-monsoon seasons and the samples were collected between 9:30-11:30 am. The main causes of lower DO value in the present study were the presence of organic matter in the water body, lack of sunlight in the morning (7.30-8.30 am), nutrients from induced fertilizers, human activities and other animal wastes.…”

The present study was undertaken to investigate some water quality parameters (pH, BOD, DO and water temperature), anion concentration ( 524to the users of the river water but also poses risks for the aquatic organisms especially fish of the water bodies. So the occurrence of high bacterial load concluded that the water of Dhaleshwari river is polluted and unhygienic for drinking and even unsuitable for domestic purposes without proper treatment.
