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)

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.

Major Chemical

Analyses are presented of major chemical features of pans and lagoons in the sub-humid regions of Tasmania. The waters sampled are classed as fresh or saline, using a criterion which is a function of relative ionic composition. Saline waters are regarded as having ionic composition limited by the solubility of alkaline earth carbonates, and they have a composition akin to that of seawater. The fauna of salt pans is briefly mentioned. These analyses complete a survey of Tasmanian surface waters, and some relationships between ionic concentrations and other chemical parameters are reassessed for the entire salinity range (<10 ppm to > 200‰) of Tasmanian inland waters.
