Research ArticleOpen accessIn the keywordsAssessment of The Biological Integrity of The Native Vegetative Community In A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC. C. Galbrand, A. M. Snow, Abdel E. Ghaly, R. CôtéA study was conducted to evaluate the biological integrity of a constructed wetland receiving landfill leachate and stormwater runoff from the Burnside Industrial Park, Dartmouth, Nova Scotia. The biological integrity of the constructed wetland was tested in the second growing season using vegetative community monitoring. The metrics analyzed were species diversity, species heterogeneity (dominance) and exotic/invasive species abundance. There was … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 6,998 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHydraulic Flow through Engineering Bentonite-Based Containment BarriersEric Wooi Kee Loh, Devapriya Chitral WijeyesekeraThis paper presents the use of software modelling as a tool to study the impact of hydraulic "resistivity" on the contaminant transport through bentonite-based containment barriers. A sensitivity analysis on the predicted data was carried out by varying the boundary conditions as well as the hydraulic resistance to flow through varying contaminant transport parameters. Accordingly, both advective and diffusive flow … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 4 Nov 2015 · 6,703 accessesView PDFCite
Case ReportOpen accessIn the keywordsSteady State Groundwater Flow Modeling of an Ex-Landfill Site in Kuala Lumpur, MalaysiaMustapha Atta, Wan Zuhairi Wan Yaacob, Othman Bin JaafarEffective and rational management of groundwater resources require adequate information on the groundwater flow interactions with surface water and chemical species in the flow regime. The hydrologic conditions beneath the unlined ex- landfill site in Jinjang Kuala Lumpur were investigated to understand the groundwater flow and geochemical setting in which contaminants transport in the groundwater may occur in the ex-landfill. … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 30 Oct 2015 · 8,092 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPhysical Composition, Nutrients and Contaminants of Typical Waste Dumping SitesH. Meuser, K. S. Grewal, R. Anlauf et al.Problem statement: The composition of wastes is quite variable depending upon the generating source and mode of collection. Most of the material from the domestic activities will be organic in nature and contains essential plant nutrients, whereas the dumping material of commercial and industrial wastes usually contains appreciable amounts of heavy and potentially toxic metals and organic pollutants. Approach: Objective … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,753 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEstablishment and Evaluation of the Vegetative Community in A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC.C. Galbrand, A.M. Snow, A.E. Ghaly, R. CôtéA surface flow constructed wetland, designed to curve in a kidney shape in order to increase the length to width ratio to 5:1 was used to treat runoff from an industrial park. A natural wetland system located approximately 200 m downstream of the constructed wetland was selected to act as the vegetative community model for the constructed wetland. The selected … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Compost Production from Fruit and Vegetable Market Waste: A Case Study in Bagua, Amazonas (Peru)Juan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Wilfredo Ruiz Camacho, Juan Francisco Robles RuizInadequate management of organic solid waste in municipal markets represents a critical environmental challenge in tropical developing regions, where high humidity (>80%) and elevated temperatures (>25°C) accelerate decomposition, generating leachate and greenhouse gas emissions. In Peru, over 50% of municipal waste is organic, yet less than 20% is valorised through composting, highlighting a substantial technological gap. This study evaluated an … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 11 Aug 2026 · 1,262 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeaching of a Nigerian Refractory Gold Ore Using Aqua RegiaOluwasanmi Samuel Teniola, Abraham A. Adeleke, Simeon Ademola Ibitoye, Moshood Deinde ShituIn this research, refractory gold ore from Imogbara deposit in Iperindo area of Osun state Nigeria were collected systematically from various segments of the deposits at different depths to obtain a set of samples that truly represent the deposits. The 50 kg sample collected was subjected to panning in a flowing river to obtain about 1 kg-upgraded sample. The upgraded … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 13 Mar 2022 · 7,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractAir Quality Measurement at the Solid Waste Disposal of Matuail Landfill Site at Dhaka, BangladeshMd. Faruque Hossain, ASM Maksud Kamal, Abdul Halim Farhad Sikder, Zakia ParveenAn investigation was conducted to assess the air quality impact and possible health risk of solid waste disposal on surrounding environment of Matuail landfill site in Dhaka city. Three different locations were selected for soil and plant samples. Leachate samples were collected from active dumping area and fish samples from treated leachate pond. Seven different locations were selected for air … …American Journal of Environmental Sciences, Vol. 15, Issue 5 · 31 Oct 2019 · 8,348 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Household Wastes in D.R. Congo, a Case Study of LubumbashiMartin T. Mpinda, Sissou Zakari, Olusegun K. Abass et al.The insufficient supervision of household solid waste is a notorious problem in DR. Congo cities. Besides, solid waste management in Lubumbashi has been very rudimentary and unsystematic. This study aims to quantify and characterize the household solid waste in two Lubumbashi municipalities. For more than 50 years after independence from colonialism, the city trailed direct discharge of waste on exposed … …American Journal of Environmental Sciences, Vol. 13, Issue 3 · 10 Jun 2017 · 8,217 accessesView PDFCite
