Research ArticleOpen accessIn the abstractRecovery of Lead(II) from Aqueous Solutions by Zea mays Tassel BiosorptionCaliphs M. Zvinowanda, Jonathan O. Okonkwo, Nana M. Agyei et al.Problem statement: Major adsorbent materials used in heavy metal ion removal from polluted aqueous streams are expensive and difficult to regenerate. In this study, the possibility of using Zea mays tassel, as an alternative low cost biosorbent material to remediate heavy metal pollution was investigated. Lead (II) was used because of its wide application in industrial products and well documented … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractConcentration of Zn, Cu and Pb in Some Selected Marine Fishes of the Pahang Coastal Waters, MalaysiaB. Y. Kamaruzzaman, M. C. Ong, S. Z. RinaProblem statement: Heavy metals constitute one of the most hazardous substances that could be accumulated in biota. Fish populations exploited by man often live in coastal area environments that contain high levels of heavy metals, coming from human activities such as industrial and agricultural wastes. A problem to deal when using fishes as biomonitors of heavy metals is the relationship … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 10,011 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuitability of Using Phragmites australis and Tamarix aphylla as Vegetation Filters in Industrial AreasWafa’a A. Al-TaisanProblem Statement: Many soils of different areas of the world are subjected to heavy metal pollution due to human activities especially the industry. These metals are hazardous to human health and could affect ecosystems. Toxic metal pollution in water and soil is a major environmental problem and most conventional remediation approaches do not provide acceptable solution, hence the studies of … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metals Analysis and Sediment Quality Values in Urban LakesAboud S. Jumbe, N. NandiniProblem statement: The objective of this research was to evaluate the degree of heavy metal contamination in lakes and the extent to which the sediment quality of the lakes of Bangalore city has deteriorated. Approach: In this study, heavy metals such as Cd, Co, Cu, Cr, Mn, Pb, Ni and Zn in lake bed sediments were analyzed using comparative sediment … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 9,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of Metals (Pb and Cu) Contamination in Bottom Sediment from South China Sea Coastal Waters, MalaysiaM. C. Ong, B. Y. KamaruzzamanProblem statement: The accumulation of metal contaminants in sediments can pose serious environmental problems to the surrounding areas. Trace metal contamination in sediment could affect the water quality and the bio-assimilation and bioaccumulation of metals in aquatic organisms, resulting in potential long-term implications on human health and ecosystem. Approach: About 154 bottom sediment samples were collected using Smith McIntyre in … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,995 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Methylene Blue from Aqueous Solution onto a Low-Cost Natural Jordanian TripoliAtef S. ALzaydienProblem statement: It is well documented that lead is one of contaminants of industrial wastewaters and its pollution exists in the wastewater of many industries. As a result, recent research has focused on the development of cost effective alternatives using various natural sources and industrial wastes. In this setting, the use of low-cost agricultural materials, waste and residues for recovering … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,949 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Typical Case Study: Solid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanThe current environmental concerns have forced developed and developing countries to reduce air, water and land pollution for sustainable growth. Solid refinery waste is cocktail of hydrocarbons, water, heavy metal and fine solids and is substantial in quantity. The principal processes of waste management focus mainly on waste source reduction, reusing, recycling, composting, incineration with or without energy recovery, fuel … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 9,773 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHeavy 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 · 6,052 accessesView PDFCite
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 · 6,443 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Heavy Metals on the Enzymatic Activity of Haplic Chernozem under Model Experimental ConditionsNatalia Gromakova, Saglara Mandzhieva, Tatiana Minkina et al.The biological activity of soils is an essential parameter of their ecological status. The anthropogenic Heavy Metals (HMs) disturb the normal functioning of soil biota and, hence, the entire soil system. The aim of this work was to estimate the toxicity of loosely bound HM compounds in Haplic Chernozem using parameters of cellulose-degrading and urease activities. Contamination of Haplic Chernozem … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 23 Jul 2017 · 7,996 accessesView PDFCite
