Review ArticleOpen accessPhrase in the titleThe Synopsis of Environmental Heavy Metal PollutionAnyiam N. Donald, Pene B. Raphael et al.Heavy metal pollution continues to be a serious problem in the environment due to uncontrolled pesticide use, mining, foundry operations, smelting, fossil fuel burning and sewage sludge dumping. Mercury, lead, chromium, cadmium, copper and other heavy metals are non-biodegradable and remain in the environment in regions where human activity is prevalent. Heavy metal contamination is a serious hazard to all … …American Journal of Environmental Sciences, Vol. 18, Issue 5 · 7 Dec 2022 · 8,323 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleSpatial Distribution and Evaluation of Heavy Metal Pollution in Soil Based on Three-Dimensional Model and Kriging InterpolationBaoshun Liu, Yonghong Zhang, Jun Yao, Jian SuSoil heavy metal pollution is an important content for soil environmental governance. Based on the three-Dimensional (3D) geological modeling technology and ordinary Kriging method, this study described and analyzed the soil pollution status and spatial distribution characteristics of a site in Zhongshan, Guangxi. The results showed that combining 3D geological model and the Kriging interpolation method can well evaluate soil … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 2 · 10 Jun 2022 · 6,144 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA 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 accessEvery word in the titlePollution Characteristics and Sources Analysis of Soil Heavy Metal in Taoyuan Coal Mine of Suzhou CityHaimin SuSoil is one of the most important resources and an important part of ecosystem in the development of human survival. The purposes of this study are to investigate concentration characteristics and sources analysis of heavy metals in Taoyuan coal mine of Suzhou City. 30 soil samples were collected and characterized for metal concentration (Cd, Cr, Cu, Pb, Zn and As), … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 29 Jan 2022 · 5,914 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison 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 accessEvery word in the titleAssessment of Heavy Metal Cu, Pb, Cd Contamination in Dust in Zahedan City using Pollution Indices and GIS and Geo Statistics Technologies, Zahedan, IranKaveh Ostad-Ali-Askari, Hossein Gholami, Meysam Madadi et al.Assessment of heavy metal contamination is of great importance given its hazardous impacts on humans and the environment. Atmosphere is an important path for heavy metals transportation and plays a major role in the bioaccumulation of heavy metals in the environment. The present research aims to assess soil pollution to heavy metals of lead, copper and cadmium in Zahedan using … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 30 Dec 2020 · 6,860 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeasonal 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 accessEvery word in the titleThe Content of Heavy Metal in the Labu Riverbed Sediments: An Assessment of the Level of Pollution Applying Sediment Quality Guidelines and Geoaccumulation IndexAhmad Shoaib Jahesh, Sahibin Abd Rahim, Wan Mohd Razli IdrisRiver bed sediments from thirteen (13) sampling stations, from Labu River were collected in June and December 2014. The aim is to identify the source and ascertain the current levels of heavy metal pollutions. The selected heavy metals (Cr, Cu, Fe, Ni, Zn, As, Cd and Pb) were analysed by using Inductively Couple Plasma Mass Spectrophotometry (ICPMS). Metals were statistically … …American Journal of Environmental Sciences, Vol. 12, Issue 4 · 10 Aug 2016 · 7,402 accessesView PDFCite

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 keywordsUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,761 accessesView PDFCite
