Abstract. Geochemical investigation of the soils around quarry and barite mine sites in part of Akamkpa and Biase area of Southeastern Nigeria, was carried out to assess the concentration and enrichment levels of some heavy metals and trace elements in the soils. The investigation involved the collection of fifteen (15) soil samples between the
1,2,3,4,5,, Nigeria.) ABSTRACT: Heavy metal, chlorophyll, vitamin and proximate composition of selected vegetables in Ishiagu, Ebonyi State Nigeria as influenced by quarry effluent discharge were screened. Fresh samples of vegetables were collected from farms around Ishiagu quarry sites. Heavy metals were analyzed using Atomic Absorption
It is concluded that quarry activities in Old Netim in Akamkpa Local Government Area of Cross River State has a significant impact on the level of heavy metals on crops around the area. This is a matter of great concern in view of the environmental and health implication, since man and livestock depend on these plant species for food.
Jul 02, 2017· 3.2. Mean Heavy metal concentrations in Solanum villosum Table 2 below shows that the pattern of heavy metal concentration displayed by vanadium, manganese, iron, cobalt nickel and mercury for Solanum villosum at the three sites is similar. The content of these metals in the Solanum villosum collected upstream was low. The levels increased to maximum in the vegetables grown next
Department of Crop, Granite Quarry, Heavy Metal Enrichment, Pollution Load Index, Transfer Factor, Bioaccumulation Nigeria is an old quarry opened in 1976 . for the supply of rock
This study determined the concentration of three heavy metals zinc (Zn), lead (Pb), and cadmium (Cd) in soil and in a woody plant species, Milicia excelsa, at Ishiagu quarry, Nigeria. The highest soil concentrations of Zn, Pb, and Cd in soil were obtained at 1 m from the quarry site. In M. excelsa, the highest concentrations of Zn, Pb, and Cd were 3.12–9.1, 3.9–6.01, and 0.51–1.12 mg kg

Download this complete Project material titled; Effects Of Heavy Metals On The Air Pollution Tolerance Indices ( Apti ) Of Five Medicinal Plants Growing Within Quarry Site In Ishi-Agu, Ebonyi State, Nigeria with abstract, chapters 1-5, references, and questionnaire.
A comparative study of the influence of heavy metals on soils and crops grown within quarry environment at Akamkpa, Cross River State was conducted in 2009 year. The study area was delineated into3 zones P1, P11, P111 based on the intensity of exposure to tailings, wind speed, wind direction and distance from the quarry. The selected sample distances were (0km, 1km and 3km as control).
It was this concern that informed the characterization of soils and crop plants in selected dump sites in Nigeria with particular reference to the heavy metal content, and the assessment of the potential of the crops to mine and deploy heavy metals to their edible portion. The result showed that soils in municipal waste dump sites are higher in
several points to capture the variability of heavy metals in various locations. The analysis focused on twelve (12) metals (Pb, Zn, Cu, Cd, Ag, As, Ni, Mo, Sb, Hg, Se, and Te). The heavy metals concentrations in soil were measured at surface and near surface depth and were found to be highest in the soil around the mine areas.
for the adsorption of heavy metals from polluted sites. In this study, a biosorbent based on zeolite and Penicillium simplicissimumwas was developed to clean up heavy metals from gold mine wastewaters. Several chemical processes may be involved in biosorption, including adsorption, ion exchange, co-ordination and covalent bonding.
Apr 01, 2019· Heavy metals can cause breaks in DNA strands, molecular cross linkage, mutations of genetic materials, oxidative stress and damage by ROS and free radicals, and functional and structural membrane disintegration, which all ultimately increase the phytoavailability of heavy metals and inhibit the growth of crop plants .
The determination of the impacts of marble mining on the environment in Igarra was carried out via the analysis of soil and water samples as geological medium. Seven soil samples, ten water samples and five rock samples were collected. The samples collected were subjected to petro-graphic and geochemical analysis. The mean concentration of metals in soil from Ekpeshi were Cd (3.254 mg/kg), Co
