Research ArticleOpen accessIn the keywordsDetermination and Source Apportionment of Selected Heavy Metals in Aerosol Samples Collected from SebeleAlfred Sello Likuku, Gilbert Kabelo Gaboutloeloe, Khumoetsile B. MmolawaBush fires and dust in the dry winter months establish moderately high background levels of aerosols. Emissions into the atmosphere by copper mines, coal mines and vehicular emissions are all possible sources of air pollution with heavy metals. Although there has been assessment and monitoring of heavy metals and their air pollution in other countries such as Brazil, Europe and … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 25 Apr 2013 · 7,441 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metals Content and Ecotoxicity of Sediments from the Congo RiverDidier Makonko Mabidi, Honoré Manyingu Mutwejile, Georgette Ngakiama Beni Ngweme et al.This research aimed to quantify the contamination of Congo River sediments by heavy metals and to evaluate their ecotoxicological effects in the municipalities of Maluku, Gombe, and Kinsuka, Kinshasa Province. Metal concentrations in sediments reached 340 mg kg-1 for Cr, 310 mg kg-1 for Cu, 826 mg kg-1 for Zn, 63 mg kg-1 for as, 1.9 mg kg-1 for Cd, … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 9 Nov 2024 · 6,046 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeasonal Variation of Heavy Metal Concentrations in Farm Soils of Sreepur Industrial Area of Gazipur, Bangladesh: Pollution Level AssessmentMd. Billal Hossain, Md. Nurul Islam, Mohammad Shamsul Alam, Md. Zakir HossenA study was conducted to measure the seasonal variation of different heavy metal contents in farm soils of Sreepur Upazila of Gazipur district and to assess their pollution level. Industrial affected and non-affected soil samples were collected from 5 locations in three seasons viz. pre-monsoon (April), monsoon (August), and dry season (January), thus a total of 30 soil samples were … …American Journal of Environmental Sciences, Vol. 16, Issue 4 · 6 Aug 2020 · 7,408 accessesView PDFCite
Research ArticleOpen accessIn the abstractReduction of Microbial Contamination of Outlet Waste in Urban Wastewater Treatment PlantsSona Pazdar, Saeid Eslamian, Hossein Gholami, Kaveh Ostad-Ali-AskariThe available research was managed to monitor the physicochemical and microbiological features of treatment plants. The wastewater treatment herb sewage is a straight pollution input source for anthropogenic pollution. The sediment information ideas to an urban drainage trench as a secondary point pollution source while the organotins information highlights the presence of other spread sources, special to this material. wastewater … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 18 Sep 2019 · 7,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractVirtual Assessment of air Pollution Dispersion from Anthropogenic Sudden ExplosionMarvel Lola Akinyemi, Moses Eterigho Emetere, Mojisola Rachel UsikaluThe control of air pollutants from anthropogenic sources seems almost impossible due to numerous influencing factors present in the atmosphere. In this study, we carried out a virtual mathematical experimentation using Math CAD, Mat lab and analytical approximation to estimate the dimensional impact of initial pollutant plume cloud from a sudden volcanic blast and the dynamics of its wind field. … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 9 Apr 2016 · 7,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Sewage Sludge in Agricultural Soil as Fertilizer in the Republic of Benin (West Africa): What are the Risks of Heavy Metals Contamination and Spreading?Fidèle Suanon, Lyde A.S. Tomètin, Biaou Dimon et al.Biosolids are the treated organic residuals, also known as sewage sludge, which are generated from domestic wastewater treatment plants. It is an organic matter and nutrients [phosphorous (P) and nitrogen (N)]-rich material. Due to these properties, it is has been reported to be a suitable fertilizer or soil amendment which can valuably replace synthesized NPK. Unfortunately, this matter is heavily … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 6 Jan 2016 · 14,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractPREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Seasonal Physicochemical Parameters in River UsmaA. I. Ugwu, R. J. WakawaGrowing populations may put stresses on natural waters by impairing both the quality of the water and the hydrological budget. Abuja, being relatively a new city and the new Federal Capital Territory of Nigeria, has scarce physicochemical data on its water resources that could assist in making robust decision in mitigating the impact of human societies on natural waters; which … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 20 Sep 2012 · 9,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractVertical Profile of C, N, P, K and Radionuclides in Soil Collected from Highland Tea Plantation AreasZaini Hamzah, Seh Datul Riduan, Ahmad SaatProblem statement: Cameron Highlands is a well known agricultural area in Peninsular Malaysia. Long term usage of fertilizer has caused accumulation of major elemental component in the soil. This accumulation will cause enrichment of the nutrient in the catchment located at downstream of the river through runoff. Approach: Two tea plantations on the upstream with hilly condition plantation were selected … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of the Water Quality Index of Otamiri and Oramiriukwa RiversA.N. Amadi, P.I. Olasehinde, E.A. Okosun, J. YisaProblem statement: The impact of anthropogenic activities on Otamiri and Oramiriukwa Rivers as a result of the increasing rate of urbanization in Owerri, Nigeria is of a great concern due to the fact that water from these rivers is the source of water distributed for public use. These rivers are of particular importance in the study of surface water pollution … …Physics International, Vol. 1, Issue 2 · 31 Dec 2010 · 8,546 accessesView PDFCite
