Variations in the flow and pollutants concentrations during the day were monitored at the Main Outfall disposal station of the city of Lahore. The laboratory analysis of the wastewater samples collected at 2 hour interval on 5 th and 6 th May, 2009 for pH, temperature, alkalinity, hardness, Biochemical Oxygen Demand (BOD5), BOD5Filtered, Total Kjeldahl Nitrogen (TKN), Ammonia Nitrogen (NH3-N), ...

in this research, the groundwater quality of abhar plain was studied for drinking, domestic and irrigation uses. to assess the evaluation of hydrochemistry and quality, 26 groundwater samples were collected and analyzed for the physicochemical factors such as ph, electric conductivity (ec), total dissolved solids (tds), total hardness (th), na+, k+, ca2+,mg2+, cl-, so42-, hco3-, co32- during oc...

Abstract A total of seventy irrigation water samples were collected from Leh, Ladakh, India, to determine their hydrochemistry profile and quality for purposes. Water indices such as hardness (TH), residual sodium carbonate (RSC), potential salinity (PS), permeability index (PI), Kelly's ratio (KR), absorption (SAR), corrosivity (CR), chloroalkaline (CAI) measured. The Piper diagram, Durov's Un...

Water pollution and its consequences for humans agriculture compelled us to examine a variety of water quality indicators. We used testing methods, including the Wrinkler's method, EDTA procedure, pH meter, others. Ganges samples are analyzed their physicochemical properties. Throughout months April May 2010, were taken from several locations in around Kanpur. To determine importance indicators...

The early, highly time-variable X-ray emission immediately following GRBs exhibits strong spectral variations that are unlike the temporally smoother emission which dominates after t ∼ 10s. The ratio of hard channel (1.3-10.0 keV) to soft channel (0.3-1.3 keV) counts in the Swift X-ray telescope provides a new measure delineating the end time of this emission. We define TH as the time at which ...

The water quality represents the water’s physical, chemical and biological properties depends on environment, anthropogenic influences. Recently, river in Dehradun has subjected to immense pressure due contamination from indecorous land use urbanisation. In this study area, assessment is carried out with help of situ observations satellite surface reflectance October 2018 March 2019. Physicoche...

U-Th zircon SHRIMP and U-Th-total Pb monazite CHIME ages of 6 typical samples were established among different rock types outcropped into the Chah-Dozdan batholith from Iran. The zircon population displays simple internal structures in samples of the Chah-Dozdan batholith. The zircon crystals have well-preserved magmatic characteristics. In all population, the rims display younger ages than the...

AIM The study evaluates the microbial as well as physicochemical pollution of groundwater of Brij region of Uttar Pradesh, a major tourist destination in the country along with estimating the drug resistance evident in the isolated Escherichia coli. MATERIALS AND METHODS A total of 60 samples of groundwater were collected from six different sites and assessed for physicochemical (pH, color, t...
