“…Temperature can decide the rate of biochemical responses in the aquatic ecosystem (Simon et al 2011). Water temperature of Al-Gharraf river ranges 17-33°C during the year of the study and there was a slight difference among stations but large among seasons reflecting the weather condition of the area.…”

Water quality of Al-Gharraf river, the largest branch of Tigris River south of Iraq, was evaluated by the National Sanitation Foundation Water Quality Index (NFS WQI) and the Heavy Metal Pollution Index (HPI) depending on 13 physical, chemical, and biological parameters of water quality measured monthly at ten stations on the river during 2015. The NSF-WQI range obtained for the sampling sites was 61-70 indicating a medium water quality. The HPI value was 98.6 slightly below the critical value for drinking water of 100, and the water quality in the upstream stations is better than downstream due to decrease in water and the accumulation of contaminants along the river. This study explains the significance of applying the water quality indices that show the aggregate impact of ecological factors in charge of water pollution of surface water and which permits translation of the monitoring data to assist the decision makers.

“…The time elapsed between collection and incubation of samples was not higher than 6 hours, aiming to prevent the occurrence of problems reported in ZANONI (1965), APHA (2012) and SIMON et al (2011), such as loss of viability of the sample (consumption of organic material).…”

Studies on the effects of temperature and time of incubation of wastewater samples for the estimation of biodegradable organic matter through the biochemical oxygen demand (BOD), that nowadays are rare, considering that the results of the classic study of STREETER & PHELPS (1925) have been accepted as standard. However, there are still questions how could be possible to reduce the incubation time; whether the coefficient of temperature (θ) varies with the temperature and with the type of wastewater and if it approaches 1.047. Aiming the elucidation of these questions, wastewater samples of dairy, swine and sewage treated in septic tanks were incubated at temperatures of 20, 30 and 35 °C, respectively for 5, 3.16 and 2.5 days. From the parameter of deoxygenation coefficient at 20 °C (k 20 ), θ 30 and θ 35 were calculated. The results indicated that θ values changes with the type of wastewater, however does not vary in the temperature range between 30 and 35 °C, and that the use of 1.047 value did not implied significant differences in obtaining k in a determined T temperature. Thus, it is observed that the value of θ can be used to estimate the required incubation time of the samples at different temperatures. C, e que o emprego do valor de 1,047 não implicou diferenças significativas na obtenção de k para uma determinada temperatura T. Assim, observa-se que esse valor de θ pode ser empregado caso se queira estimar o tempo necessário de incubação das amostras em diferentes temperaturas. KEYWORDS

“…BOD (Biochemical Oxygen Demand) is defined as the amount of oxygen required by aerobic microorganisms to dissolve organic matter in a sample of water. It is one of the most essential and widely used parameters for the most essential and widely used parameters for measuring pollutants and biodegradable organic compounds in water [14], [25], [17]. Low the BOD, higher the desirability of using for human use, like drinking & domestic purposes.…”

Abstract:The Kushiyara River basin is located in the north eastern region of Bangladesh. The aim of this study is to investigate the water quality parameters seasonal variation on the basis of physico-chemical analysis such as Temperature, P H , DO (Dissolved Oxygen), BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), TS (Total Solids), TDS (Total Dissolved Solids) and SS (Suspended Solids) in both rainy season and winter season for the years 2010 to 2013. The rainy season data is collected during June-July and the winter season data is collected during November-December for each of the year. Our ultimate outcomes will convey a sound message for the government body and policy maker to rules and regulation in order to keep ecological balance as well as save our environment. We therefore suggest wise management of anthropogenic actions in the catchment of Kushiyara River.
