Research ArticleOpen accessIn the abstractTraditional Aquaculture Practice at East Calcutta Wetland: The Safety AssessmentS. Raychaudhuri, M. Mishra, S. Salodkar et al.The current study is on East Calcutta Wetland (ECW) which is a model for multi-use resource recovery system with activities like pisciculture and agriculture. The entire city's soluble waste is disposed into the raw sewage canals which finally drains into the shallow, flat bottom fish ponds called Bheri. These sewage fed fisheries act simultaneously for the purification process like removal … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 9,436 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTrace Metal Mercury Levels in Residential Homes in KuwaitL. AL-Awadi, A. R. Khan, R. Al-KandariKuwait is an oil rich state on the northeastern corner of Arabian Peninsula and has faced the unprecedented man made environmental disaster in early 1991 of igniting over 600 oil wells those continually burnt for a period of over six months. The use of crude and heavy fuel oil in the power generating facilities has aggravated the pollution due to … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 6,827 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudies on Metal Microbe Interaction of Three Bacterial Isolates From East Calcutta WetlandV. K. Adarsh, Madhusmita Mishra, Sanhita Chowdhury et al.The present paper put forth the isolation and complete characterization of three bacterial isolates from different sites of East Calcutta Wetland (ECW). These isolates show tolerance to heavy metals like Ag, Al, Cu, Cr, Co, Ni, Pb and were found to be efficient metal accumulators as evident from Energy Dispersive X Ray Fluorescence (EDXRF) analysis and Transmission Electron Microscopy (TEM). … …OnLine Journal of Biological Sciences, Vol. 7, Issue 2 · 31 Dec 2007 · 9,423 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetoxification of Heavy Metal Contaminated SoilsFloarea Damian, Gheorghe DamianThe concentration of the heavy metals in the soils from the strong affected zones because of the mining and metallurgical industry, Baia Mare and Zlatna (Romania), is significant due to the high values of the contents and association of the four metals Pb, Cu, Zn, Cd. The efficacy of the natural zeolites in heavy metals immobilization from the studied soils … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 7,233 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffective Coagulation Technology for Treatment of Grease Filter WashwaterAbdel E. Ghaly, A. Snow, B.E. FaberThe treatment of grease filter washwater by chemical coagulation and sedimentation using different dosages of aluminum sulfate was investigated. Pollutant removal efficiency was measured in terms of total solids, pH and optical density. The process was found to be effective at the room temperature and the filter washwater pH (9.5). The optimum aluminum sulfate dosage was 2 g/L. The treatment … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 6,816 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of Fluoride and Other Ions on Algae and Fish of Coastal Water of Mediterranean Sea, EgyptM. S. Masoud, W. M. El-Sarraf, A. A. Harfoush, G. F. El-SaidSea grass, marine algae and fish samples were collected from the Egyptian coast of Mediterranean Sea during September 2000 and March 2001. The contents of fluoride and some interfering ions (calcium, magnesium, sulphate, phosphorus and some heavy metals) ions and their concentration factors were determined in the dried samples. Fluoride contents in macrophytes, algae, muscle of fish samples were ranged … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,265 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSupporting the Josephson Interpretation of Low Energy Nuclear Reactions and Stabilization of Nuclear WasteF. Osman, H. Hora, X. Z. Li et al.Brian Josephson appealed at the meeting of the Nobel Laureates July 2004 against the ignorance of physicist to the phenomenon of cold fusion. Though there are good reasons against many publications on this topic but not for all what was reported. It seems to be indicated to summarize the following serious, reproducible and confirmed observations on the reactions of protons … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,162 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPhytoremediation and Adsorption of Heavy Industry Emitted from Cement Industry through Plant Leaves, Case Study: Golestan Peivand Cement FactorySoleyman Ghorbanzadeh, Meysam Madadi, Sara Abdollahi, Kaveh Ostad-Ali-AskariCement factories are found to be one of the major causes of pollution. Cement mist and dusts depositions affect the photosynthesis, secretion and fertility of the plant. Increasing the concentration of airborne dust reduces photosynthetic potential in leaves, closes leaf stomatals and, in general, reduces the growth and fertility of plants. The purpose of this study is to determine the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 23 Nov 2020 · 6,438 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHEAVY METAL ANALYSIS IN RED OAK (QUERCUS RUBRA) POPULATIONS FROM A MINING REGION IN NORTHERN ONTARIO (CANADA): EFFECT OF SOIL LIMING AND ANALYSIS OF GENETIC VARIATIONAnh Tran, K. K. Nkongolo, M. Mehes-Smith et al.Understanding the dynamic of metals in soil and plants and population diversity in Northern Ontario is essential in determining progress toward ecosystem sustainability in reclaimed sites. The objectives of the present study were to assess the levels of metal content in soils and their accumulation in red oak plants from limed and unlimed sites. Genetic variation in red oak populations … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 25 Jun 2014 · 7,732 accessesView PDF Cite
