Assessment of heavy metals in seasonal lakes near balloki head works and comparison of their water quality
Five seasonal lakes situated near Balloki Head Works near River Ravi in Qasur district, Punjab, Pakistan were studied for the comparison of their water quality and heavy metals contamination in water, sediments and hydrophytes of the lakes. In the assessment of water quality physicochemical parameters i.e. pH, Electrical Conductivity, Dissolved Oxygen, Salinity, Total Dissolved Solids, […]
Buccal deformities in Chironomid larvae (Diptera: Chironomidae) as an indicator Risk Assessment and Anthropogenic stresses of pollution in fresh water of the River Nile, Sohag Governorate, Egypt
Mouth parts deformities in chironomid larvae are considered as indicators of environmental stress in aquatic systems caused by water and sediment pollution such as heavy metals, pesticides as well as organic contamination. Fourth instar chironomid larvae were collected from two sites (SI and SII) located in the River Nile, Sohag Governorate, Egypt. The chironomid community […]
Quality Analysis of Potable Water at Dakshin Khan in Dhaka City, Bangladesh
The aim of this study was to assess the physiochemical and microbiological quality of DWASA supplied drinking water in Dakshin khan area, Dhaka, Bangladesh. A total of twenty one water samples in three groups were collected from DWASA water supply pumps, house taps and tube wells. The physiochemical properties i.e. Dissolved Oxygen, pH, Total Dissolved […]
Correlation between water quality and seagrass distribution along intertidal zone in Sarangani Province, Philippines
This study aimed to determine the correlation between certain properties of water quality and the distribution of seagrasses in the coastal areas of Glan and Maasim, Sarangani Province. Both sites have no previous correlation studies. At each site, three 50m transects were laid perpendicular to the shore with each transect having 11 quadrats at 5m […]
Evaluation of Drinking Water Quality in Urban Areas of Pakistan. A Case Study of Gulshan-e-Iqbal Karachi, Pakistan
A study was carried out to evaluate the quality of water supplied by Water and Sanitation Agency (WASA), Karachi. Gulshan-e-IQbal was selected for this purpose. Water samples from different source (12 houses) connections (one from each) were collected making a total of twelve sampling points. Physicochemical parameters (pH, Eh, turbidity, conductivity, temperature and total dissolve […]
Comparative Study of Three Commercial Strains of Saccharomyces for Enhanced Production of Biofuel Using High Gravity Molasses
The potential of different commercial strains of Saccharomyces cerevisiae was studied for enhanced production of bioethanol under high gravity condition. Three strains i.e. Rossmoor, Saf-instant and Uvaferm-43, were compared in order to select best commercial yeast that could be utilized on industrial scale for production of bio-ethanol. Osmotic pressure is one of the main stress […]
Impact of environmental conditions on the yield variability of durum wheat (Triticum durum. Desf) and its associated characters at Algerian semi-arid areas
The environmental stresses are most common in Algeria. Drought, cold and hot weather are often present. These production constraints are abiotic, they are combined together more aggravating the loss in crop yields, especially durum. Indeed, a study was conducted under different agro-ecological conditions in the 2010/11 year. The approach adopted has been characterized by integration […]
The reservoirs and potentials of perlite in Iran (A case study on perlite reservoirs of middle cenozoic volcanic zone of Mianeh in East Azerbaijan province)
Perlite is a type of volcanic stone with acidic composition which forms in water environment. It has a glass-like texture in which spherical shapes are formed (i.e. water content of 3 to 5 percent). Heating the perlite (700 to 1200 °C) contributes to its loss of molecular water content and increase of volume up to […]
Dominance and diversity of forest plant species growth on post coal mining soil in the Samarinda City, East Kalimantan Province, Indonesia
A post coal mining land contains soil physicochemical properties that are not suitable for plant growth as well as contained high heavy metal. Only resistance plants species would be able to survive in those conditions. Utilization of forest plant species to rehabilitate and remedy an ex-coal mining land at the same time supports biodiversity conservation […]
Surface water quality assessment in Gilan Province, Iran
Surface water in Gilan province is assessed in order to determine its hydrogeochemistry and irrigation water quality using 55 water samples. In this regard, concentration of major ions and physicochemical parameters including Ca2+, Mg2+, Na+, K+, HCO–3, Cl–, SO42- and CO2-3 pH, EC and TDS were determined. The average content of the major cations and […]
