Research ArticleOpen accessIn the abstractLong Term Ageing Effect on Physical and Shear Strength Characteristics of Oil Contaminated Sandy Soils of Al-Ahmadi Field in KuwaitHumoud Melfi Aldaihani, Fahad A. Al-OtaibiSerious environmental damage was caused to Kuwait when more than 600 oil wells were set alight following the 1991 Gulf War, leading to hydrocarbon contamination and a series of ‘oil lakes’ being created in the desert. The effects of these highly damaging actions are still detectable today, 27 years later. The main contribution of this paper is that the effects … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 1 Apr 2019 · 8,060 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Pollution by Heavy Metals in the Gold Mining Region of East CameroonDallou Guy Blanchard, Ngoa Engola Louis, Abdourahimi et al.The main objective of this study is to assess the level of heavy metals pollution in soil samples collected around gold mines located in Betaré Oya (BO) and Batouri (BA) in Eastern Cameroon. Elemental analysis of soil samples was carried out using Quant´X EDXRF spectrometer. Its sensitivity and accuracy were increased by using the Fundamental Parameter approach for quantification of … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 7 Nov 2018 · 9,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantile Regression Estimation Using Non-Crossing ConstraintsIlaria Lucrezia AmeriseIn this article we are concerned with a collection of multiple linear regressions that enable the researcher to gain an impression of the entire conditional distribution of a response variable given a set of explanatory variables. More specifically, we investigate the advantage of using a new method to estimate a bunch of non-crossing quantile regressions hyperplanes. The main tool is … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 15 May 2018 · 7,700 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Microbial and Heavy Metal Contents in Soils and Roots under Mangrove Forest Stands with Different Levels of Pollution in the Niger River Delta, NigeriaAroloye Ofo NumbereOil and gas exploration in the Niger Delta, has resulted to increased heavy metal contamination. It is thus postulated that increased heavy metal will lead to decreased microbial content in soil and root. To test this hypothesis ten replicates each of soil and root samples were collected from already established sites. Samples were sent to the laboratory for analyses of … …American Journal of Applied Sciences, Vol. 15, Issue 2 · 25 Jun 2017 · 8,177 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metals Content of the Grassland Soil around Katima Mulilo Municipal Solid Wastes Dumpsite, NamibiaJ. Abah, P. Mashebe, S.A. OnjefuThe effects of open wastes dumpsites on the immediate vicinity continue to generate safety concern. This study determined the levels of lead, chromium, cadmium, arsenic, nickel, cobalt, copper and manganese in soil samples collected at two depths: 0-15 and 15-30 cm within and around Katima Mulilo municipal solid wastes dumpsite and a control site. The samples were digested according to … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 18 Mar 2017 · 7,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Resistance Evaluation of Dry Subtropics Brown Soils to Heavy Metal and Oil Contamination by Biological IndicatorsSergey Ilyich Kolesnikov, Natalya Aleksandrovna Petrova, Kamil Shagidullovich Kazeev et al.Contamination of brown calcareous soils with Cr, Cu, Ni, Pb and oil leads to deterioration of their biological properties. There is a reduction in activity of catalase and dehydrogenase, an abundance of Azotobacter genus bacteria, cellulolytic activity and the length of radish roots. As a rule, there is a direct relationship between the content of contaminant in the soil and … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 5 Aug 2016 · 7,883 accessesView PDFCite
Research ArticleOpen accessIn the abstractLead in Meat and Meat Products Consumed by the Population in SlovakiaLukáčová Anetta, Golian JozefThe presence of heavy metals in food is the consequence of atmosphere contamination of polluted soil, waters and results in contaminated feed with heavy metals. The lead concentrations depend on the environmental conditions and the food production methods. The monitoring of lead concentration in meat is important for human health. The aim of this study was to determine the level … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 4 · 24 Dec 2014 · 7,926 accessesView PDFCite
Research ArticleOpen accessIn the abstractSPATIAL AND MULTIVARIATE ANALYSIS OF TRACE ELEMENTS IN THE SURFACE WATER AND DEEP SEDIMENTS OF FRESH WATER AQUATIC ECOSYSTEMKantha Deivi Arunachalam, Sathesh Kumar Annamalai, Kamesh Viswanathan Baskaran et al.The aim of this study was to assess the levels of various trace metals present in water and sediment of fresh water aquatic ecosystem during the post monsoon season. The study was extended to identify the trace metal contamination in the water and sediment samples collected along the shores of Lambapur and Peddagattu the tribal villages in India using an … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 26 Mar 2014 · 7,597 accessesView PDFCite
