Research ArticleOpen accessIn the abstractAssessment of Constructed Wetland Biological Integrity Using Aquatic MacroinvertebratesC. Galbrand, I. G. Lemieux, Abdel E. Ghaly et al.A surface flow constructed wetland consisting of seven cells was used to treat the leachates from a decommissioned landfill. Wetland monitoring was performed by evaluating the treatment efficiency of the landfill leachate and the wetland biological integrity of the wetland. The water quality samples were analyzed for iron, manganese, phosphorus (orthophosphate), pH, dissolved oxygen (DO), nitrogen (ammonia, nitrate, nitrite and … …OnLine Journal of Biological Sciences, Vol. 7, Issue 2 · 31 Dec 2007 · 7,415 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Water Quality in RiversLiren Yu, N. N.B. SalvadorThis study reports a PC software, used in a Windows-based environment, which was developed based on the first order reaction of Biological Oxygen Demand (BOD) and a modified Streeter and Phelps equation, in order to simulate and determine the variations of Dissolved Oxygen (DO) and of the BOD along with the studied river reaches. The software considers many impacts of … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonitoring Water Quality Parameters of the Transboundry River NestosPsilovikos Aris, Margoni Sophia, Psilovikos AntoniosThe Nestos/Mesta river, shared by Greece and Bulgaria, needs monitoring system along its course for sustainable management and environmental preservation. Such a system, known as R.E.MO.S., was installed in the year 2000 and operates since then on a 24 h basis at a station in the river deltas channel. It records water level, water and air temperature, conductivity, redox potential … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethyltert-butyl Ether (MTBE) Degradation by a Microbial ConsortiumS. B. Mortazavi, A. Nikpey, A. Rezaee et al.Methyl tert-butyl ether (MTBE) is added to reformulated gasoline to meet the 1990 Clean Air Act directives. Widespread use of MTBE in gasoline has resulted in groundwater contamination. Because of its undesirable effects on drinking water and ecologically harmful effects, MTBE removal has become a public health and environmental concern. In this study, we have isolated a mixed bacterial culture … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,994 accessesView PDFCite
