Water quality assessment has been carried out in the Hakaluki Haor of greater Sylhet district during May, 2013 to February, 2014. Water samples were collected from 5 spots during 4 seasons and a total of 15 physico-chemical parameters were studied. Significant seasonal variation was observed in all seasons among physico-chemical parameters. pH values varied from 5.9 - 7.1, water temperature varied from 23.7 – 26.7OC, transference varied from 23-53 cm, TSS varied from 18.1-192 mg/l, TDS varied 25-193.5 mg/l, EC varied from 30-680 ?s/cm , DO content of water varied from 4.6 - 5.6mg/l, BOD varied from 0.2-2.614 mg/l, COD varied from 38-312 mg/l, NO3-N varied from 0.1-30.4 mg/l, NH3 varied from 0.9-2.18 mg/l, alkalinity varied from 12-42 mg/l and PO4 varied from 0.9 -13.4 (mg/l). Agricultural and inorganic pollutants have been observed as the main causes of the Haor water pollution.Jahangirnagar University J. Biol. Sci. 3(2): 67-72, 2014 (December)

Present study was carried out to determine the important physico chemical parameters of water of Tapi estuary in Hazira industrial area. Tapi estuary receives the inputs of organic matter and nutrients coming from the domestic wastewater discharges from Surat City, a textile hub as well as industrial effluents from Hazira, a major industrial Complex of Gujarat, India. Uncontrolled discharges of domestic wastes and industrial effluents have affected the estuary. Present study was carried out from June - 2011 to May 2012 to study the impacts of uncontrolled discharges on physicochemical characteristics of water. Samples were collected monthly in the morning during low tide to determine the important physico chemical parameters Viz. Turbidity, conductivity, total solid, total dissolved solid, salinity, pH, dissolved oxygen, BOD, COD, Calcium, chloride, sodium , potassium and nutrients like nitrate, nitrite and phosphate. Dissolved oxygen was found extremely low during the study period. High biochemical oxygen demand (BOD) and Chemical Oxygen demand (COD) showed that the water quality of estuary has been affected by industrial and domestic effluents.

Standard Level

Water samples were collected from three points of Louhajong river (Dighulia, Kagmari Bridge and Oloa) to see the seasonal variation in physico-chemical parameters. The results revealed that some of the parameters such as TDS, alkalinity and acidity have exceeded the standard level in dry season in all of the points, which are unsuitable for different purposes including fish culture. During dry and wet seasons the highest concentrations of BOD was recorded as 2.0 and 0.8 ppm at Kagmari Bridge (point-2) respectively. DO ranged from 1.4 to 3.1 and 2.4 to 3.8 ppm during dry and wet seasons. Maximum and minimum EC was recorded as 890 and 130 ?s/cm at Dighulia (point-1) during dry and wet seasons. The results suggest that at wet season Louhajong river may be suitable for fish culture and other purposes.Bangladesh J. Sci. Res. 28(1): 9-16, June-2015

The present study is carried out during the period of January, 2020 to December, 2020 to investigate seasonal variation of the zooplankton in Song river, Gularghati, District Dehradun. During study period total 22 zooplankton species were found belonging to different groups. Protozoa consist of 8 species, rotifera consist of 7 species, copepoda consist of 5 species and two species of ostrocoda. The number of zooplankton was highest in summer season followed by winter and monsoon season.
