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 · 7,317 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Study of SEM-EDX and ICP-MS Detection Based on Gunshot Residue Originated from AK-47 and M16 RiflesYaowaluck Phermpornsagul, Suphareark Arepornrat, Worasit Palkawong Na Ayuthaya, Panya KhaenamkaewThis is a comparative study on Gunshot Residues (GSR) originated from AK-47 and M16 rifles by SEM-EDX and ICP-MS. The GSR samples were obtained from multiple body parts of the shooter (hand, cloth and helmet) with elapsed times, as well as from multiple shooting occasions. The SEM-EDX data established the different shapes and dimensions of the GSR samples and the … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 30 Apr 2020 · 8,753 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Risk Assessment of Coal-Ash-Amended Soil Based on Continuous Planting of PakchoiWenxuan Sun, Liyong Bai, Huihui Ji et al.The agricultural application of coal ash which contains a variety of chemical nutrients may also cause heavy metal pollution of crops and soil. In this study, pakchoi was cultivated for four consecutive seasons in pots of brown soil amended with fly ash or bottom ash. With subsequent plantings, the total concentrations in the four fractions of Pb, Cr and Cu … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 11 May 2021 · 6,864 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremedial Potential of Tagetes Erecta Under Mycorrhizal Inoculation in Heavy Metal Polluted SoilI.O. Aina, F.L. Amusa, A.D. Olasupo et al.Investigation of the growth of Tagetes erecta under different levels of contamination of Copper (Cu) and Lead (Pb) in the soil and effects of mycorrhizal species (Glomus mosseae) on Cu and Pb to identify hyperaccumulator plants in tropical environment that could be used in remediation of heavy metal from contaminated soils. It was a greenhouse experiment consisted of factorial combination … …American Journal of Environmental Sciences, Vol. 15, Issue 5 · 28 Oct 2019 · 7,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Seasonal Variations on Typha capensis and Heliconia psittacorum in the Remediation of Heavy Metals from Soil and WaterWiafe Samuel, Buamah Richard, Owusu MichaelDifferent plant species have been used in the remediation of different heavy metals. The performance of a macrophyte to remediate heavy metals may be dependent on a lot of factors which may include water chemistry, metal solubilityand temperature. The objective of this research was to ascertain the effects of seasonal variations on the remediation of heavy metals. To this end,two … …American Journal of Applied Sciences, Vol. 15, Issue 12 · 31 Jan 2019 · 7,791 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial-Dynamics of Trace Metals Accumulation and Physicochemical Characteristics in Ikpukulu-Ama Creeks, Rivers State, NigeriaDavies Ibienebo Chris, Khang Wen Goh, Davies Imachrist Ibienebo et al.The study examines the spatial-dynamics variability of water parameters and trace metal concentrations between January and June 2023 at the Ikpukulu-Ama sites of the Bonny River, Nigeria. Key parameters analyzed include temperature, salinity, pH, transparency, dissolved oxygen, and trace metals (Ni, Pb, Cd, Cu, Zn) across three sites. The highest temperature, 32.56°C, was recorded at Site 2, indicating potential thermal … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 29 Jul 2026 · 499 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotentiometric Biosensor for Highly Toxic Pb (lead) and Cd (cadmium) Detection in Milk Using Layer-by-Layer ImmobilizationZhainagul Kakimova, Klara Zharykbasova, Aitbek Kakimov et al.Milk contamination with heavy metals such as lead (Pb) and Cadmium (Cd) poses a serious threat to public health, particularly in industrial regions. To address the need for rapid and on-site detection of these contaminants, a potentiometric biosensor was developed for the quantification of Pb²⁺ and Cd²⁺ ions in milk and dairy products. The biosensor functions by measuring the change … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 8 Feb 2026 · 1,484 accessesView PDFCite
