Research ArticleOpen accessIn the keywordsThreat of the Health Quality of Garden Produces Linked to Pollution by Toxic Metals on Some Gardening Sites of BeninKoumolou Luc, Edorh A. Patrick, Agbandji Lucien et al.Problem statement: Water and soil are vital resources used in agriculture. Current data establish a link between the pollution of soil, water and public health. For this reason, this study attempted to establish a link between the level of pollution of garden sites in lead (Pb), Cadmium (Cd) and Arsenic (As) and the health quality of vegetables grown there, through … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 23 Apr 2012 · 7,664 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 · 5,022 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeaching of a Nigerian Refractory Gold Ore Using Aqua RegiaOluwasanmi Samuel Teniola, Abraham A. Adeleke, Simeon Ademola Ibitoye, Moshood Deinde ShituIn this research, refractory gold ore from Imogbara deposit in Iperindo area of Osun state Nigeria were collected systematically from various segments of the deposits at different depths to obtain a set of samples that truly represent the deposits. The 50 kg sample collected was subjected to panning in a flowing river to obtain about 1 kg-upgraded sample. The upgraded … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 13 Mar 2022 · 7,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Heavy Metals Contamination in Controlled and Uncontrolled Landfill Soil, Ouagadougou, Burkina FasoBambara Telado Luc, Doumounia Ali, Kohio Nièssan et al.The study was conducted to evaluate the concentrations of heavy metals in landfill soils. The soils samples were collected in some selected landfill, at Ouagadougou. Determinations of heavy metal concentrations, calculation of contamination factor and pollution load index of heavy metal in landfill soil were undertaken. The atomic absorption spectrophotometer was used to determine the concentrations of heavy metals (Cr, … …American Journal of Environmental Sciences, Vol. 16, Issue 4 · 2 Sep 2020 · 7,311 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 abstractNew Golden Red Sodium Calcium Silicate GlassesWang Cheng-Yu, Wun Nuan-Xin, Ge Yi et al.Traditional golden red glasses were based on K2O-PbO-SiO2 composition system. In this paper, we reported new golden red glasses based on Na2O-CaO-SiO2 system without SnO2 and PbO in them. By using a spectrophotometer and chromamter color difference meter, it was found that the new glasses had similar optical properties to the traditional ones. The diameter of the gold particles in … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 13 Feb 2019 · 7,061 accessesView PDFCite
