Research ArticleOpen accessIn the abstractModeling the Evolution of Nitrate Pollution of Groundwater in the Plain of Western Middle CheliffNessrine Belmiloud, Naïma BettaharGroundwater constitute a potential source of drinking water supply and should, consequently, benefit from the necessary protection against the various forms of pollutions, particularly those diffuse of agricultural origin. The plain of Western Middle Cheliff which contains an important resource in groundwater supplying the whole population of the province of Chlef and contributing to the satisfaction of the need for … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 12 Jan 2016 · 7,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcological Studies of Epiphytic Microalgae and Epiphytic Zooplankton on Seaweeds of the Eastern Harbor, Alexandria, EgyptN. G. Shams El-Din, N. A. Shaltout, M. Z. Nassar, A. SolimanA qualitative and quantitative study on the epiphytic microalgae and epiphytic zooplankton were conducted in order to follow up their community structures on seaweeds in relation to some physico-chemical variables in the coastal waters of the Eastern Harbor of Alexandria. Water and macroalgal samples were collected seasonally during two years successively: Winter, summer, autumn (2012) and spring (2013). The collected … …American Journal of Environmental Sciences, Vol. 11, Issue 6 · 9 Dec 2015 · 7,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatus of Heavy Metals in Water and Sediment of the Meghna River, BangladeshMahmud Hassan, Mirza A.T.M. Tanvir Rahman, Badhan Saha, Abdul Kadir Ibne KamalThe pollution of river water and sediments by heavy metals has assumed serious problems due to their toxicity and accumulative behavior. The present study has been undertaken to assess the levels of heavy metals and the extent of pollution in the surface water and sediments from the Meghna river. Water and sediment samples were collected by the Standard Methods and, … …American Journal of Environmental Sciences, Vol. 11, Issue 6 · 24 Nov 2015 · 12,843 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of Pesticide Residue in Dams and Well Water in Jazan Area, Saudi ArabiaHasan Y. Al-Hatim, Deifalla Alrajhi, Abdul Jabbar Al-RajabThe application of pesticides indoors and on agricultural lands increased dramatically in recent years in the Jazan area (Saudi Arabia) to control termites and the vectors of diseases, such as Rift Valley Fever (RVF) and malaria. This practice increased the potential risk of pesticide contamination of surface water and groundwater. In this study, samples of 44 wells and 3 dams … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 3 Nov 2015 · 7,952 accessesView PDFCite

Research ArticleOpen accessIn the abstractCLIMATE CHANGE IMPACT ASSESSMENT ON WATERSHED HYDROLOGY: A COMPARISON OF THREE APPROACHESSomsubhra Chattopadhyay, Manoj K. JhaSeveral methods of impact assessment have been developed over the years which basically incorporate future climate projections of atmospheric-ocean circulation based climate models into the simulation of land surface hydrological processes. This study attempted to evaluate three methods of climate change impact assessment: (a) Frequency perturbation method, (b) direct method and (c) delta change method. A well-calibrated hydrologic model, Soil … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 27 Mar 2014 · 8,604 accessesView PDFCite
