Research ArticleOpen accessIn the abstractComparability Assessment of Polycyclic Aromatic Hydrocarbons Tissue Load in Some Fish: Implication on Reciprocal Synergism and Risk AssessmentVictor Eshu Okpashi, Ogugua Victor Nwadiogbu, Joshua Parkar Elijah et al.Six years after oil spill occur in Qua Ibeo river, environmental monitoring was set out to investigate residual petroleum compounds (PHCs) that are bio-accumulated by fish. Bio-concentration of residual Polycyclic Aromatic Hydrocarbons (PAHs) in fish tissues was determined in six fresh fish species. Twelve water samples were collected from Qua Ibeo river 1 KM apart. The screening was conducted using … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Apr 2017 · 7,543 accessesView PDFCite
Review ArticleOpen accessIn the abstractThe Status of Pollutants in the Three Gorges Reservoir Area, China and its Ecological Health AssessmentChun-Jiao Lu, Dan Luo, Muhammad Junaid et al.The Three Gorges Reservoir Area (TGRA) stretches along the Yangtze River from Jiangjin District, Chongqing to Yichang, Hubei in China. Since TGRA is the main source of drinking water and fresh fishery in China for millions of people, both researchers and the government have concerns for environmental pollution and ecological security in the TGRA. This review highlighted the status and … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 28 Sep 2016 · 7,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentifying Nutrient Contributors in North Carolina’s Coastal Plain Blackwater RiversNarayan B. Rajbhandari, Sushama Pradhan, Mauro Di Luzio et al.The goal of this study was to assess potential nitrogen and phosphorus contribution from point sources and non-point sources in North East Cape Fear River (NECFR) watershed in North Carolina. A watershed scale hydrologic model, Soil and Water Assessment Tool (SWAT), was used to quantify Total Nitrogen (TN) and Total Phosphorus (TP) loadings to North Carolina’s Coastal Plain Blackwater Rivers. … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 5 Nov 2015 · 7,393 accessesView PDFCite
Case ReportOpen accessIn the abstractSteady 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 · 8,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpacts of Large-Scale Stormwater Green Infrastructure Implementation and Climate Variability on Receiving Water Response in the Salt Lake City AreaChris York, Erfan Goharian, Steven J. BurianThis study evaluated impacts of Green Infrastructure (GI) as a stormwater management practice on return flows and the further Implications of climate variability. The goal was to create a model to explore the impacts that bioretention and Rainwater Harvesting (RWH) representing GI had using goldsim and Stormwater Management Modeling (SWMM) software. The software was used to represent impacts that climate … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 20 Oct 2015 · 9,275 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Converting Tropical Peat Swamp Forest into Oil Palm Plantation on Water QualitySeca Gandaseca, Noraini Rosli, Mohd Hanafi Idris et al.Peat swamp forest is a unique forest and wetlands ecosystem that recognized as one of the most important reservoir of biodiversity and water resources protection. Rapid development particularly for development, agriculture and plantation in peat swamp forest (PSF) area had given negative impacts to its ecosystem included degradation of its water quality. This study was conducted to determine water quality … …American Journal of Applied Sciences, Vol. 12, Issue 8 · 3 Sep 2015 · 7,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Land Cover on Streamflow Variability in a Small Iowa Watershed: Assessing Future VulnerabilitiesKeith Schilling, Matthew Streeter, Kasey Hutchinson et al.Agricultural expansion and urbanization, coupled with climate change represent major threats to the sustainability of river ecosystems and infrastructure. In this study, we evaluated how subbasins with different dominant land covers within the 27.5 km2 Clear Creek, IA watershed affect key hydrologic indicators. Hydrologic output from two stream gages and a calibrated Soil Water Assessment Tool (SWAT) model were used … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 6 Jul 2015 · 8,374 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaccumulation and Tissue Partitioning of Endosulfan by the Red Hybrid TilapiaDwight E. RobinsonThe frequent use of endosulfan in agricultural activity on steep slopes in Jamaica and subsequent contamination of rivers by the residues resulted in a need to assess the levels of bioaccumulation of sub-lethal doses of the insecticide in river fauna using Tilapia fish as a test subject. Bioconcentration of α- and β-endosulfan by the Red Hybrid Tilapia, from 0.0075 mg … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 29 Jun 2015 · 7,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Soil and Water Assessment Tool Model to Estimate Sediment Yield in Kaw LakeD. Alemayehu, R. Srinivasan, P. DaggupatiKaw Lake is one of the reservoirs built by the Army Corps of Engineers in 1976 for the purpose of flood control, recreation, water supply, navigation and fish and wildlife conservation. The Arkansas River flows from Colorado and Kansas before reaching Oklahoma. As it passes through these states, the water carries various kinds of pollutants such as metals from mine … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 16 Dec 2014 · 8,276 accessesView PDFCite
