The levels of cadmium, copper and nickel in five different edible vegetables viz Talinum triangulare, Celosia trigyna, Corchorus olitorus, Venomia amygydalina Telfaria accidentalis, the soils on which they were grown from three industrial residential areas Lagos City, Nigeria, determined using atomic absorption spectrophotometry . results obtained for these heavy metals higher than those as a result pollution. Industrial area ranged between 1.13 1.67_g/g cadmium; 56.84 25.08_g/g 2.06 -...
In this article we present lead concentrations and isotopic compositions from analyses of cocoa beans, their shells, soils six Nigerian farms, manufactured chocolate products. The average concentration beans was </= 0.5 ng/g, which is one the lowest reported values for a natural food. contrast, products were as high 230 70 respectively, are consistent with market-basket surveys that have repeatedly listed in among highest all foods. One source contamination finished tentatively attributed to...
Globally, the available amount of freshwater is unevenly distributed due to problems associated with climate change, inefficient water management and pollution. This has led increased demand for worldwide. Heavy metals, in particular are a group pollutants (mostly from domestic, agricultural industrial activities) major concern aquatic environment their toxicity. Existing technologies heavy metals’ removal waters wastewaters often ineffective (especially at environmental levels), expensive...
In-vessel composting, a contribution to sustainable solid waste management, was conducted on source-separated materials generated in Abeokuta city, south-west Nigeria. Feedstock (household, agricultural and municipal waste) the resultant composts were chemically characterized using standard procedures. Identification changes microbial population during effects of composting volume reduction (WVR) elemental composition evaluated. Product performance plant growth metal uptake then assessed...
Abstract Laboratory investigations into the possibility of using local Nigerian clays in refining crude palm oil revealed that Okija clay may possess some potential as an adsorptive cleanser process. Activated bentonite was used standard comparison, and performance two natural clays, leached with various concentrations sulfuric acid, evaluated for their use alternative cleansers oil. Measurements peroxide values, para‐anisidine carotene content stabilities oils active oxygen method were...
Abstract Application of stable isotopes in soil studies has improved quantitative evaluation evaporation and other hydrological processes soil. This study was carried out to determine the effect tillage on evaporative loss water from Zero conventional were compared. Suction tubes installed for collection at depths 0.15, 0.50, 1.0 m by pumping with a peristaltic pump. Soil estimated using water. The mean isotopic composition 0.15 depth -1.15‰ (δ 18 O) -0.75‰ (δD) highly enriched compared...
This is the eighteenth annual review published in JAAS of application atomic spectroscopy to chemical analysis environmental samples. The follows on directly from last year's (J. Anal. At. Spectrom., 2002, 17, 284-317), and once again uses revised format which includes less tabulated material. It was recognized by group that some tables were becoming comprehensive this form information better more easily obtained using electronic searches. We therefore critically report most important...
Abstract Lacquered metal cans, green glass bottles, amber clear bottles and plastic filled with freshly produced Nigerian crude palm oil were stored in direct sunlight (40±1°C) the dark (27±1°C). Assessment of stability oils towards hydrolytic oxidative deterioration was made periodically by measuring free fatty acid, peroxide anisidine values over a period 98 days. The study showed that packaged recorded higher total oxidation than either lacquered cans or bottles. gave greatest protection...
Maize cob was used as an adsorbent in order to evaluate its potential for the removal of lead from aqueous solutions and effluents battery paint industries with Dowex (synthetic resin) control. Experimental data were analyzed terms Freundlich isotherm model. Equilibrium attained at 2 h adsorption rate constants maize dowex 7.26 x 10-2 7.58 min-1, respectively. pH value 6; shaking 150 rpm enhanced maximum by both adsorbents effluents. Optimal weight equilibrium Pb2+ solution 16 mg/L solution....
Breast milk is an essential source of nutrients and energy for infants. The study analyzed the levels essential, toxic rare earth elements in breast lactating mothers within Abeokuta metropolis.Thirty-seven (37) samples were collected with consents at Ogun State General Hospital Abeokuta. digested using standard method Inductively Coupled Plasma Mass Spectrometer (ICP-MS). data subjected to descriptive analysis.The results showed higher concentrations than mothers, where five metals: Ag, Ti,...
Balancing farming practices and environmental protection to promote human health
Heavy metal contamination of soil, water, and crops, their health impact on residents, is a persistent social issue, several studies have identified risks residents living near abandoned mines. In this study, the heavy concentrations in soil plants gold mines primary goldmine secondary goldmine, Ilesa-Osun State Nigeria latitude 7°, 27’N to 7°,35’N longitude 4°, 47’E 4°,53’E was investigated. A total 20 samples replicates two [both surface (0 to15 cm) subsurface (15 30 cm)] were collected...
