Research ArticleOpen accessPhrase in the titleSpatial-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 · 494 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleValidating Trace Metals Levels in PM2.5 Aerosols from Indoor and Outdoor Polluting PremisesA. H. Bu-Olayan, B. V. ThomasProblem statement: Our studies revealed high trace metals concentrations in PM2.5 aerosols from Residential Buildings (RB-I) and enclosed Car Parks (CP-I) indoor than in outdoor Residential Buildings (RB-O) and Car Parks Outdoor (CP-O), indicating possible dust accumulation in confined premises from six Kuwait Governorate areas. Approach: Trace metals in PM2.5 was high in the sequence of Bed Room (BR) >kitchen … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,381 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleGeochemical Distribution of Trace Metals and Assessment of Anthropogenic Pollution in Sediments of Old Nakagawa River, Tokyo, JapanH.M. Zakir, Naotatsu Shikazono, Kazuo OtomoThe geochemical distributions of cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn) were examined in sediments collected from Old Nakagawa River (NR), Tokyo, Japan. A widely used 5-step sequential extraction procedure was employed for the fractionation of the metals and the concentrations were measured in the liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS). The association … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,453 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTrace Metal Effect on Hydrogen Production Using C.acetobutylicumHisham Alshiyab, Mohd Sahaid Kalil, Aidil Abdul Hamid, Wan Mohtar Wan YusoffThis study was carried out to study the effect of trace metal addition for hydrogen production The results show that this bacterial need a selected nutrient with selected concentration. The optimum parameters for cultivation were at initial pH of 7.0 and temperature of 30°C. Trace metal addition to the new medium showed that only iron enhanced the H2 yield. The … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 7,635 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTrace 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 PDFCite
Research ArticleOpen accessPhrase in the titleAssessment of Camel Meat Pollution with Trace Metals in Desert Area of Basra ProvinceSarmad G. Mohammed, Hassan T. Abdulsahib, Ibrahim M. Jasim, Mushtak T. JabbarProblem statement: This study investigates the possibility of the camel meat pollution in south of Basra province (Iraq). Trace elements concentrations (Mg, Fe, Pb and Hg) were determined from different tissues of camel (neck, shoulder, plate, leg and loin) from two location in Basra governorate, Safwan and Al-Zubair. Approach: The study focused on the assessment of camel meat pollution on … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 27 Oct 2011 · 8,300 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTrace Metals Co-Toxicity in Hard Body Structures of Liza klunzingeri (Mugilidae: Perciformes) Mullet FishA.H. Bu-Olayan, B.V. Thomas, S.M.H. Al-HusainiThe possibility of inorganic pollutants causing stress to the marine ecosystem instigated us to conduct eco-toxicological tests on the predominant trace metals (Cu, Zn, Pb and V) in commercial important fish. Among the four metals, V had the lowest observed effect concentration (LOEC: LC15) at 6.3 µg L-1. Toxicity tests (96 h) using Multi factor Probit analysis revealed V (6.3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,514 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLevels of Trace and Other Selected Metals in Mixed Teff Grain SamplesAbraha Gebregewergis WeldehawariaTeff (Eragrostis tef (Zuccagni)) is a hugely important crop to Ethiopia both in terms of production and consumption.

Research ArticleOpen accessIn the keywordsBaseline Concentrations of 11 Elements as a Function of Land uses in Surface Soils of the Katangese Copperbelt Area (D.R. Congo)Martin T. Mpinda, Tresor N. Kisimba, Theodore M. Mwamba et al.The Katangese Copperbelt Area (KCA) located south-eastern of D.R. Congo presents high concentration of Metal Trace Elements (MTE) due to a rich natural geochemical background and intense mining activities. However, the lack of data on specific baseline concentrations makes it difficult to assess and monitor the environmental quality of soils in the region. In this study, 11 MTE were measured … …American Journal of Environmental Sciences, Vol. 17, Issue 6 · 3 Jan 2022 · 7,126 accessesView PDFCite
