The impact of potentially harmful elements in stream sediments around active and abandoned artisanal gold-mining communities in Nigeria was assessed in this study in order to determine their level of contamination and evaluate the associated health risk. Thirty-fve (35) stream sediment samples were collected within an active mine (ACM-19 samples),...

Toxic metals exuding from mining remain a challenge to the environment and human health. This study investigated the distribution, contamination, toxicity, and potential risks of toxic metals in rocks, soils, sediments, and tailings from a typical Pb-Zn-F mineralization zone in Nigeria. In this study, 64 samples which include soils, stream sediment...

The overwhelming environmental significance of solid waste has attracted a lot of attention because of its leaching into groundwater through waste deposit. The study determines impact of leachate from a landfill site on the quality of groundwater sources in Shagamu, Southwestern, Nigeria. Twelve groundwater samples, (hand dug wells (7) and borehole...

This investigation was done to decide the concentrations, sources and potential risks of metals in media around Ijero area. A total of 80 samples including topsoils, sediments, tailings and whole plants were gathered from this territory while control samples were taken from zone with less human exercises. Samples were pounded, sieved and chemically...

Background. Exposure to heavy metals emanating from cement production and other anthropogenic activities can pose ecological risks. Objectives. A detailed investigation was carried out to assess the contamination and ecological risk of heavy metals associated with dust released during cement production. Methods. Sixty samples, including 30 soils an...

AbstractFormulae display:MathJax Logo? Toxic metals are deleterious to the environment. In this study, risks associated with metals in water from Anka area, Nigeria were unraveled. A total of 104 water samples were collected. The concentrations of metals were determined using high performance liquid chromatography–inductively coupled plasma-mass sp...

Background. Groundwater quality can be poor in Nigeria due to indiscriminate refuse dumping. Exposed dumps serve as point source pollution that discharge potentially toxic heavy metals into the environment. Objectives. The present research aimed to assess the impact of metal pollution on groundwater quality in hand-dug wells around an active dum...

In recent times, there had been reported cases of Pb poisoning in Anka gold mining area, Northwest Nigeria. Therefore, this study was carried out to determine the extent of bioaccumulation of heavy metals in the hairs and nails of children in the area. Forty samples (twenty nails and twenty hairs) samples were collected from ten boys and ten girls...

Geochemical assessment of groundwater was carried out within the basement complex of Ibadan, southwestern Nigeria, in order to establish the impact of urbanization on public health. Physical parameters were determined using insitu digital analytical instruments and samples that were collected were simultaneously analyzed. Geochemical analysis of gr...

Land reclamation is gradually posing negative impact on man due to unplanned urbanization. A study was carried out on impact of land reclamation through sand mining of coastal communities in Ikate and Ilubirin in Lagos, Nigeria. Ten waters (8 surface and 2 groundwater sources), 10 soil samples and air were collected and taken for analysis. Results...

Electrical resistivity investigation was carried out at Olabisi Onabanjo University campus, Ago-Iwoye, Southwestern Nigeria with the aim of evaluating groundwater potential and aquifer protective capacity of the overburden units in the area. The underlain rocks are predominantly porphyroblastic and banded gneiss, quartz-schist and biotite-hornblend...

The geophysical assessment of groundwater in Awa-Ilaporu, near Ago Iwoye southwestern Nigeria was carried out with the aim of delineating probable areas of high groundwater potential. The area falls within the Crystalline Basement Complex of southwestern Nigeria which is predominantly underlain by banded gneiss, granite gneiss and pegmatite. The ge...

Azimuthal cross-square array resistivity soundings were used to detect fractures and investigate the anisotropic properties of crystalline basement rocks in some parts of Eruwa, southwestern Nigeria. Resistivity measurements were taken at ten locations using an Ohmega terrameter. The technique involves the rotation of the electrode array in four di...

Rapid population in developing nations has imposed stress on groundwater resources, thus the need to assess physicochemical and bacteriological impact of microbes on hand-dug wells along some major markets in Ibadan Southwestern Nigeria. Water samples from hand-dug wells were measured sequentially, and total dissolved solute (TDS), pH, electrical c...

Pollution of groundwater has become a major environmental problem. Anthropogenic impacts on groundwater within different zones of Abeokuta, Southern Nigeria were evaluated. The study area was divided into four zones; Crowded, Market, Residential and Industrial areas. Groundwater samples were randomly collected from hand dug wells and boreholes and...

The need for assessment of suitability of groundwater resources for drinking and irrigation purposes become pertinent in the face of continuous increasing global pollution threats of groundwater This work assesses the physical and chemical characteristics of the local groundwater resources around Ago Iwoye, southwest, Nigeria, to determine its suit...

Arsenic, a toxic metal, can be sourced from both rocks and effluents, with its health implications; hence the need for geochemical evaluation of water sources to determine the level of arsenic concentration, and propose remediation method in case of future pollution of the metal in the metropolis. Thirty water samples were randomly taken in the stu...

Increasing the supplementation from 0 to 250 mgCu/kg with Copper sulphate pentahydrate, CuSO 4 .5H 2 O and Copper proteinate (CuP) increased hen day egg production and Haugh unit while the feed intake, feed per dozen egg laid decreased. Whole egg and egg yolk cholesterol concentrations were significantly lowered and more cholesterol was excreted in...
