Heavy Metals In Crops From Quarry Sites In Nigeria . 2019-6-24grown in areas near quarry sites take up heavy metals. Upon consumption of these crops by man, there is accumulation of the metals in the body system and such buildup may reach very harmful levels 6. This is the major cause of heavy metal toxin in man.

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
heavy metal sources, their accumulation in the soil and the effect of their presence in water and soil on plant systems. The aim of this work therefore, is to determine the content of heavy metals in vegetables from a suspected contaminated site of irrigated farmlands around Barnawa area in Kaduna City.

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 depth of 15 30 cm.

Oct 24, 2017 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

toxic heavy metals within the surrounding environment of quarries and serve as reference point for future studies and comparison. This study assessed the levels of Pb, Cd, Cr, Cu, Co, Mn, Ni, Zn, and Fe in topsoil samples of a major limestone quarry in Oluyole Local Government Area, Oyo State, Nigeria.
Heavy metals in soil Statistical analysis of the concentration of heavy metals in the soils (dump sites and control) is presented in Table 1. Table 1:Heavy metals concentration from solid waste dump sites in Eagles island, Eneka and Bundu water side and control sites in Norwan, Ndele and Choba farmlands.(Mean ± SD, N=3). As compared
Apr 18, 2020 Quarry activities are creating diverse stress on biological resources in the rural areas where most of them are located globally. In this study, the effect of quarry activities on elephant grass (Pennisetum purpureum) leaves and soils around Onigambari Forest Reserve, Oyo State, Nigeria, were investigated. Soil and samples of elephant grass (Pennisetum purpureum) leaves were collected from
Aug 01, 2012 This study assessed lead, cadmium, and nickel level in food crops, fruits and soil samples from Ohaji and Umuagwo and Owerri in South Eastern Nigeria and estimated the potential health risks of metals. Samples were washed, oven-dried at 70–80°C for 24 h and powdered. Samples were digested with perchloric acid and nitric acid. Metals were analysed with Unicam Atomic

mean concentrations of heavy metals from at least 5 sam-pling sites, and Cref indicates the evaluation criteria values [21]. The adopted evaluation criteria for this study was the recommended values for agricultural soil by the Canadian Council of Ministers for the Environment [22], as Nigeria has no stipulated guideline for heavy metals in soil.
