In order to investigate the accumulation and bio-absorption of lead and cadmium in radish and cress, the present study has been conducted in a completely randomized design in three replicates in a hydroponic growing medium. The first factor includes the plant type at two levels (radish and cress), and the second factor is consisted of lead (Pb) (first experiment) at two levels (50 and 100 mg/L)...

The use of biosorbents for heavy metal removal has revealed enormous potential of algae for biosorption. The dried biomass of Spirogyra hyalina was used as biosorbent for removal of cadmium (Cd), mercury (Hg), lead (Pb), arsenic (As) and cobalt (Co) from aqueous solutions atdifferent initial concentrations of the heavy metals and contact time of the biomass. The results showed that highest amou...

From many years, it has been well known that the metabolism and toxicity of xenobiotics may be modified by various factors, including intake of bioelements and proteins as well as using stimulants, especially ethanol. Until now interactions of ethanol with drugs have been recognized relatively well. However, interdependences between ethanol and many xenobiotics, including heavy metals such as c...

Anthropogenic and agricultural activities are deteriorating drinking water quality of the Siling reservoir. Spatio-temporal variations and risk assessment of select heavy metals (Zn, Cu, Mn, Fe, Cr, Cd, and Pb) were investigated in water samples. During summer Mn (37.32 μg/L), Fe (41.0 μg/L), and Cd (1.18 μg/L) concentrations were higher in the water samples, while the concentrations of Zn (86....

Three consecutive years of field experiments were carried out to investigate the effect of different root-zone temperatures, induced by the application of mulches, on the concentration and accumulation of Cd and Pb and on bioindicators (chlorophylls, catalase, peroxidase and cell wall fractions) in different organs of potato plants (roots, tubers, stems, and leaflets). Four different plastic co...

Reactions of heavy metals with soil are important in determining metal fates in the environment. Sorption characteristics of two heavy metals, Cd and Pb, in three tropical soils (Mollisol, Oxisol, and Ultisol) from Puerto Rico were assessed at varying metal concentrations (0 to 1.2 mM) and pH values (approximately 2 to 7). All soils sorbed more Pb than Cd. Sorption maxima were obtained for each...

DETERMINATION OF Cd AND Pb IN FUEL ETHANOL BY FILTER FURNACE ELECTROTHERMAL ATOMIC ABSORPTION SPECTROMETRY. A method was developed for quantification of Cd and Pb in ethanol fuel by filter furnace atomic absorption spectrometry. Filter furnace was used to eliminate the need for chemical modification, to stabilize volatile analytes and to allow the application of short pyrolysis step. The determ...

BACKGROUND The determination of micro-, macroelements and heavy metals in the soil-grapevine-wine system is extremely important for the wine industry, the grape and wine quality, and also for consumer health. The quantitative analysis of 10 elements: Na, Ca, Mg, Fe, Cu, Zn, Pb, Cd, Ni, Co were made in soil at different depths and also in grapevines (leaves and canes). For grape juice and wine t...

In addition to the primary components of alloys, approximately 5% of the formulation may contain other metals, including lead (Pb), cadmium (Cd), arsenic, manganese (Mn), iron, phosphorus, and nickel. Workers in the foundries are exposed to several compounds; therefore, it is important to assess the levels of injury that may reflect an additive, synergistic, or antagonistic effect caused by the...
