Research ArticleOpen accessIn the abstractUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,765 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolid Waste Disposal and its Impact on Surrounding Environment of Matuail landfill Site, Dhaka, BangladeshMd. Faruque Hossain, Esrat Jahan, Zakia Parveen et al.An investigation was conducted to assess the impact of solid waste disposal on surrounding environment of Matuail landfill site of Dhaka city. Three different locations such as current dumping, abandoned and its surrounded agricultural areas of Matuail landfill were selected for soil and plant samples, leachate from active dumping and fish samples from treated leachate pond. The Cu, Zn and … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 16 Nov 2018 · 12,702 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Level of Nicotianamine Synthase (NAS3) and Natural Resistance Associated Macrophage Protein (NRAMP4) Gene Transcription Induced by Potassium Nitrate in Trembling Aspen (Populus tremuloides)Karolina M. Czajka, Kabwe NkongoloChanges in gene transcription in response to excess metal concentrations have been reported in many organisms, including yeast, microorganisms and plants. Most investigations on the effects of nickel toxicity in plants use commercial salts whose effects have not been analyzed in detail. The main objective of the present study was to determine the effects of different doses of nickel nitrate … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 15 Jul 2018 · 10,885 accessesView PDFCite
Research ArticleOpen accessIn the abstractFruit Bio-Waste Derived Bio-Ethanol Production and Bioelectricity Generation as Renewable EnergyABM Sharif Hossain, Musamm M UddinBio-waste from food industry is a significant component to pollute the environment. Bioproducts like biomaterials, biofuel can be produced from biowaste and pollution can be reduced. The study was conducted to evaluate the quality of bioethanol production and investigate the bioethanol for bioelectricity generation using rambutan fruit biowaste. Bioethanol yield was the highest in 2 days incubation period of fermentation. … …American Journal of Environmental Sciences, Vol. 17, Issue 4 · 7 Sep 2021 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe interplay between Cadmium and Zinc Induced Developmental Perturbations and Apoptosis in Daphnia MagnaNaima Hamid, Siti Nur Airina Binti Ibrahim et al.Assessing combined toxicity provides a realistic and comprehensive approach to determining toxicological effects in aquatic species under environmentally relevant conditions. This study was conducted to understand the effects of single and combined metal mixtures on freshwater flea and Daphnia magna. Environmentally Relevant Concentrations (ERCs) of Cadmium (Cd) and Zinc (Zn) at a low dose (10μg/L) and high dose (30 μg/L) … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 11 Jun 2025 · 6,021 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Heavy Metals in Gadus morhua and the Associated Cancer RisksKayode Idowu Ogungbemi, Margaret Bose Adedokun, Josephine Nneamaka Onyeka-UbakaGadus morhua is a good protein source but some methods of its preservation can be a source of heavy metals contamination. Gadus morhua samples were collected from nine major markets for the identification and quantification of heavy metals. An Atomic Absorption Spectrophotometer (AAS) from an analytical and consultancy laboratory in the Department of Soil Resources Management, University of Ibadan was … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 2 Jan 2025 · 5,032 accessesView PDFCite
EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,527 accessesView PDFCite
Research ArticleOpen accessIn the abstractRisk Assessment of Heavy Metals in Fish in Saudi ArabiaOthman M. HakamiHeavy metals such as arsenic, cadmium, mercury and lead constitute a serious threat to human health. Generally, regular consumption of fish is recommended because it is a good source of omega-3 fatty acids, which have been associated with health benefits. However, flesh of some fish species contains heavy metals in high concentration, which may pose health risk for individuals that … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 3 Dec 2016 · 8,705 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Content of Heavy Metal in the Labu Riverbed Sediments: An Assessment of the Level of Pollution Applying Sediment Quality Guidelines and Geoaccumulation IndexAhmad Shoaib Jahesh, Sahibin Abd Rahim, Wan Mohd Razli IdrisRiver bed sediments from thirteen (13) sampling stations, from Labu River were collected in June and December 2014. The aim is to identify the source and ascertain the current levels of heavy metal pollutions. The selected heavy metals (Cr, Cu, Fe, Ni, Zn, As, Cd and Pb) were analysed by using Inductively Couple Plasma Mass Spectrophotometry (ICPMS). Metals were statistically … …American Journal of Environmental Sciences, Vol. 12, Issue 4 · 10 Aug 2016 · 7,405 accessesView PDFCite
Research ArticleOpen accessIn the abstractContrasting Effects of Metal Contaminations and Soil Liming on Cations Exchange Capacity and Global DNA Methylation in Betula papyrifera Populations from a Mining RegionGabriel Theriault, Kabwe NkongoloThe Greater Sudbury Region in Northern Ontario (Canada) has been one of the most contaminated regions in the world. Soil liming with dolomitic limestone applications has decreased significantly the level of soil acidity resulting in forest regeneration. This reclamation process does not affect the level of soil metal contamination but results in metals availability decrement. The coping mechanisms of birch … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 11 Apr 2016 · 7,539 accessesView PDFCite
