Research ArticleOpen accessIn the abstractVermicompost Incorporation into Soil Contaminated with Deltamethrin as an Attempt to Reduce the Toxicity Caused by this Pyrethroid: A Structural Study of SoilFernanda Benetti, Lívia B.F. Pigatin, Michelle M. Kanashiro et al.The use of vermicompost for remediating soil contaminated with the commercial formulation containing deltamethrin was proposed. Biotoxicity tests with the goal of evaluating the potential remediation degree of the vermicompost after its addition to contaminated soils were performed. The tests lasted 56 days and involved Eisenia foetida earthworms. Possible structural changes in humic acids from these soils were evaluated by … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 16 Aug 2017 · 7,165 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Heavy Metals on the Enzymatic Activity of Haplic Chernozem under Model Experimental ConditionsNatalia Gromakova, Saglara Mandzhieva, Tatiana Minkina et al.The biological activity of soils is an essential parameter of their ecological status. The anthropogenic Heavy Metals (HMs) disturb the normal functioning of soil biota and, hence, the entire soil system. The aim of this work was to estimate the toxicity of loosely bound HM compounds in Haplic Chernozem using parameters of cellulose-degrading and urease activities. Contamination of Haplic Chernozem … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 23 Jul 2017 · 7,994 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 abstractA Comparative Assessment of Heavy Metal Pollution in Soil using pH Enrichment Factor and Pollution IndexMichael Nwachukwu, Okoro Uwaezu, Ogbuja I. Ogbuja, Leonard NwosuMany researchers have described pH as heavy metals pollution indicator in soil, but no effort has been made to determine level or quantity of heavy metals that could be indicated by pH. This study measured in-situ soil pH values at Nekede motor mechanic village against the natural background values. We used readings obtained to compute pH enrichment factor (pHeF) at … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Apr 2017 · 7,974 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 abstractWastewater Treatment Plant Performance Inside Multi-Soil-Layering SystemLamzouri Khaoula, Mahi Mustapha, Masunaga Tsugiyuki et al.Wastewater effluent disposal is a challenge in Moroccan rural area. Wastewater treatment is the only suitable solution to overcome these environmental constraints. Technology such as Multi-Soil-Layering (MSL) system is one of the most appropriate solution for the treatment of wastewater for small communities in rural areas. The MSL system overcomes many of the deficiencies of conventional soil treatment systems such … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 1 Jan 2017 · 8,027 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling the Evolution of Nitrate Pollution of Groundwater in the Plain of Western Middle CheliffNessrine Belmiloud, Naïma BettaharGroundwater constitute a potential source of drinking water supply and should, consequently, benefit from the necessary protection against the various forms of pollutions, particularly those diffuse of agricultural origin. The plain of Western Middle Cheliff which contains an important resource in groundwater supplying the whole population of the province of Chlef and contributing to the satisfaction of the need for … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 12 Jan 2016 · 7,141 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Chernozem Contamination with Lead and Oil on the Abundance and Composition of MicroarthropodsSergey Ilyich Kolesnikov, Lidiya Sergeevna Samokhvalova, Maria Gennadievna Zharkova et al.Micro arthropods population reduced with increase in the amount of oil in chernozem. The same pattern was observed up to a certain concentration of lead in the soil (background + 250 mg kg-1) and then at high doses (+500 and +1000 mg kg-1) an increase in microarthropods abundance was recorded. Gamazid mites and acaroid-trombidi form complex mites proved to be … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 29 Apr 2015 · 7,598 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
