Abstract The presented research was conducted in 2018–2019 the Peshawar Valley, Pakistan, to study for first time effect of water quality on spatial distribution charophytes. A total six taxa charophytes were found at 41 sites Valley along banks seven rivers, 16 streams and two wetlands: Chara braunii C.C.Gmelin, C. connivens Salzmann ex A. Braun, contraria Braun Kützing, globularis Thuiller, v...

Sanganur canal is the major open drainage system which has intricate linkage with storm water supply, domestic sewage and industrial effluent disposal. Water samples from various stations were collected and analysed for physicochemical parameters to assess the water quality of the Sanganur canal system. The study revealed that physicochemical parameters like pH, EC, TDS, DO, BOD, COD exceeded t...

landscape characteristics and land use patterns of watershed demonstrate extension, distribution, density and abundance of human interference. these factors can affect water quality of adjacent aquatic systems within a watershed. land use changes have caused various environmental problems for zayandehroud river,turned it as a sink of pollutant. therefore this is investigated that how would land...

Water is essential for living organisms their survival. Access of adequate and safe water a basic need human beings. In adequacy unsafe supply may cause various health problems. This study was designed with view to assessing physicochemical properties drinking collected from different restaurants at Mymensingh sadar. this case, electrical conductivity (EC), total dissolved solids (TDS), pH, oxy...

AlGaN layers grown directly on sapphire typically experience fairly strong biaxial compressive strain [1] which leads to a large number of threading dislocations (TDs) — mainly misfit TDs. These mainly occur in the form of edge/mixed type TDs. They cause very broad asymmetric high resolution X-ray diffraction (HRXRD) reflections, e.g. (102)reflexes [2]. On the other hand, screw/mixed type dislo...

Textile dye industry waste is one of the most serious problems in the environment. The dye wastes are severely deleterious to surface water bodies. The present study was an attempt for the assessment of different physicochemical parameters such as pH, temperature, Electrical Conductivity (EC), Total Solids (TS), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Dissolved Oxygen (DO), ...
