Research ArticleOpen accessEvery word in the titleDetermination of Atmospheric Turbidity and its Correlation with Climatologically ParametersU. Ali Rahoma, A. H. HassanStudy of Atmospheric turbidity is important for purposes of meteorology, ecology, climatology and monitoring of atmospheric pollution. Linke Turbidity factor (LT) is commonly used to model the attenuation of solar radiation in the atmosphere. The probable dependence on the water vapor content of the relationship linking LT to Angstrom’s turbidity coefficient B, is discussed. In this study, a procedure for … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 6,986 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUrine Turbidity and Microhaematuria as Rapid Assessment Indicators for Schistosoma haematobium Infection among School Children in Endemic AreasHassan Adesola, Ntiaidem Uduak, Morenikeji Olajumoke et al.Problem statement: Urinary schistosomiasis is highly endemic in Nigeria and for effective control measure, an efficient, quick and yet cheap diagnosis should be integrated. This will ensure the proper management of infection due to Schistosoma haematobium in low resource communities of Nigeria. Approach: This cross-sectional study recruited a total of 456 (252 males, 204 females) school children aged 3-20 years … …American Journal of Infectious Diseases, Vol. 8, Issue 1 · 21 Mar 2012 · 9,093 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimizing Coagulation Process for Low to High Turbidity Waters Using Aluminum and Iron SaltsAkbar Baghvand, Ali Daryabeigi Zand, Nasser Mehrdadi, Abdolreza KarbassiProblem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity was added as kaolin. Optimization … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 21,079 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Simulation of 2_D Turbidity Currents and Wall JetM.H. Shojaeefard, K. Goudarzi, H. Ghasvari JahromiDense underflows are continuous currents, which move down the slope due to the fact that, their density are heavier than ambient water. In turbidity currents the density differences arises from suspended solids. Vicinity of the wall make density currents and wall jets similar in some sense but Variation of density cause this flows more complex than wall jets. An improved … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,034 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication of Polyelectrolyte in Turbidity Removal from Surface WaterA. H. Mahvi, M. RazaviOne of the most important treatment processes in surface water treatment plants is coagulation. Surface waters such as rivers and lakes contain suspended particles and turbidity. With the aid of coagulants, and by flocculation process, followed by sedimentation and filtration, these impurities can be removed from raw waters these days, besides conventional chemicals such as Alum and Ferric chloride, polymers … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 8,237 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSalinity, Temperature and Turbidity Structure in the Suva Lagoon, FijiAwnesh Singh, Than AungThe city of Suva is home to nearly a quarter of the population of the Fiji thereby placing a lot of anthropogenic pressure on its lagoon. The Suva lagoon (comprising of Suva Harbour and Laucala Bay) has been subject to substantial sediment inputs generated by erosion and human activities. Freshwater input into the lagoon comes predominantly from the Rewa River, … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 8,992 accessesView PDFCite

This study was conducted to find and determine the water quality at peat swamp forest of Batang Igan, Sibu Sarawak. This study presents a status on the water quality of peat swamp forest at the area. Approach: In-situ data … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 13,152 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRemoval of Hydrogen Sulphide from WaterS. Edwards, R. Alharthi, A.E. GhalyProblem statement: The concentration of H2S in groundwater is a significant problem in various areas across Canada. Hydrogen sulphide dissolves in ground water imparting undesirable taste and irritating rotten egg smell which makes it unpalatable. Ingestion of sulphides through drinking water can result in stomach discomfort, nausea and vomiting. Humans exposed to high concentrations of H2S for prolonged periods show … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 26 Aug 2011 · 15,123 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial-Dynamics of Trace Metals Accumulation and Physicochemical Characteristics in Ikpukulu-Ama Creeks, Rivers State, NigeriaDavies Ibienebo Chris, Khang Wen Goh, Davies Imachrist Ibienebo et al.The study examines the spatial-dynamics variability of water parameters and trace metal concentrations between January and June 2023 at the Ikpukulu-Ama sites of the Bonny River, Nigeria. Key parameters analyzed include temperature, salinity, pH, transparency, dissolved oxygen, and trace metals (Ni, Pb, Cd, Cu, Zn) across three sites. The highest temperature, 32.56°C, was recorded at Site 2, indicating potential thermal … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 29 Jul 2026 · 494 accessesView PDFCite
Research ArticleOpen accessIn the abstractWater Quality in Small-Scale Coffee Production Units, Amazonas, PeruEli Morales Rojas, Segundo Chávez Quintana, Magali García et al.The objective of this research was to determine water quality in small-scale coffee production units in the Amazon Region, Peru.
