This study was focused to assess the contamination status of heavy metals in sediments, and human health risks associated with fish consumption from western Nigeria offshore Gulf Guinea. Triplicate samples demersal marine species sediments were collected five stations (fishing ground) analysed for [mercury (Hg), cadmium (Cd), lead (Pb)] metalloid [arsenic (As)] using ICP-OES (inductively couple...
2014 We analyse several amorphous Pd1-xSix alloys obtained by simulation. The metalloid atoms environments can be studied in the same way as that described in the first paper of this series. The main part of this paper is devoted to the evolution of the density as a function of the concentration. In order to interpret the values obtained by the simulation, we develop two models : the first one ...
Glassy Pd85 xCuxSi10P5 (x 1⁄4 5{12 at%) alloys with a supercooled liquid region ( Tx) of 51–73K were synthesized despite the low metalloid content. The glassy Pd79Cu6Si10P5 alloy exhibits the largest Tx of 73K in the present alloy system and its critical diameter for glass formation reaches 5mm by copper mold casting. For the bulk glassy Pd79Cu6Si10P5 alloy, the Young’s modulus, compressive yie...
The present investigation assessed the effects of a metalloid (arsenic) and two heavy metals (cadmium and mercury), on the growth and metal accumulation in two medicinal plant species, artichoke (Cynara scolymus L.) and Savory (Satureja hortensis L.). The experiment was conducted hydroponically in spiked solution with different concentrations of arsenic (0, 20, 100, and 500 µM), cadmium (0, 10,...
Varied environmental compartments including soils are being contaminated by a myriad toxic metal(loid)s (hereafter termed as "metal/s") mainly through anthropogenic activities. These metals may contaminate food chain and bring irreparable consequences in human. Plant-based approach (phytoremediation) stands second to none among bioremediation technologies meant for sustainable cleanup of soils/...
