Research ArticleOpen accessIn the abstractAssessment of Aliphatic Hydrocarbons in Sediments of Shatt Al-Arab River, Southern Iraq, North East Arabian GulfWisam Abdul-Ameer FaridShatt Al-Arab River is one of the important rivers for water supply, industry and irrigation in Basrah City, south of Iraq. It's also supply drinking water to users in the region. Despite the significance of this river, there is a lack of previous studies dealing with petroleum pollution especially for geochemical studies of organic matter in the river sediments using … …American Journal of Environmental Sciences, Vol. 13, Issue 6 · 29 Jan 2018 · 7,458 accessesView PDFCite
Review ArticleOpen accessIn the abstractCorrelation of Biodiversity of Algal Genera with Special Reference to the Waste Water Effluents from IndustriesRitu Singh Rajput, Sonali Pandey, Seema BhadauriaPollution is the introduction of contaminants, which cause adverse change, into the natural environment and mainly from external inputs like sewage, waste from industries, oil spills and agricultural use of pesticides. Anthropogenic activity-reflected in the use of toxic metals and organic pollutants-has increased levels of soil contamination and damage to aquatic systems. Ecosystems maintain water quality and withstand pressure from … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 9 Dec 2016 · 8,608 accessesView PDFCite
Review ArticleOpen accessIn the abstractEffects of Intermittent Artificial Circulation in Summer Months on Chlorophyll a Concentration in a Small Eutrophic ImpoundmentAnusha Balangoda, Shafiqur Rahman, G. PadmanabhanImpact of artificial circulation on total algal biomass (as chlorophyll a integrated over depth) in a small eutrophic impoundment in the Northern Great Plains, was monitored over three consecutive summers. Chlorophyll a concentration and nutrient concentrations were measured at depths along water columns under aerated and non-aerated conditions at four sampling locations. Aeration destratified the water column, which resulted in … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 14 Nov 2015 · 7,303 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Correlations Between Mercury Speciation and Dissolved Organic Matter in the Sediment of the Red SeaM. A. Wedyan, F. A. Ababneh, S. Al-RousanThis study addresses the correlations between Hg and organic matter in recent sediment; samples were collected from the Gulf of Aqaba, Red Sea coasts (oligotrophic regions) during 2010. In the present study TOC analyzer was used to determine Total Organic Carbon (TOC) and Total Nitrogen (TN) concentrations and the total amount of mercury (HgT) in sediment samples were analyzed by … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 21 Jun 2012 · 6,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Diatom Stratigraphy of Rawapening Lake, Implying Eutrophication HistoryTri Retnaningsih Soeprobowati, Suwarno Hadisusanto, Peter Gell, Atun ZawadskiProblem statement: The use of diatoms to reconstruct past ecological conditions in lakes is well established. Diatoms are microscopic algae that forms siliceous frustules which allow them to preserve well in sediments. Rawapening Lake is one of 15 Indonesian lakes identified as 2010-2014 National Priority Lakes. Naturally, Rawapening is a tectono-volcanic lake. In the early 1900s, the sole outlet of … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 15 Jun 2012 · 7,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractLimnological Studies on the Wetland Lake, Al-Asfar, with Special References to Heavy Metal Accumulation by FishGehan H. Fahmy, Adel A. FathiProblem statement: Al-Asfar Lake is one from the important shallow wetland lakes. It is located on the eastern region of Saudi Arabia, Al-Hassa Province. However, much of their limnology and its biotic information are still unknown to the scientific community. The study aims to follow variations in physico-chemical characteristics, phytoplankton and to determine the sort of pollutants such as heavy … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 31 Dec 2011 · 9,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecies Composition, Ecological Parameters and Seasonal Changes of Planktonic Ciliates Population in Bukan Dam ReservoirA. Mohsenpour Azary, F. Mohebbi, A. Eimanifar et al.Problem Statement: Since there is no evidence to identify present species in the Bukan dam reservoir, therefore, this study was conducted to provide background for fisheries purposes. Approach: The abundance and species composition of ciliates were analyzed in the Bukan Dam reservoir (west Azerbaijan, Iran) from January to December 2007. Surface water samples were collected at monthly intervals at two … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 7,784 accessesView PDFCite
