Trace elements in the environmental media contribute to toxicities of different types. Their presence arable pedosphere is a human-health risk factor. This study focused on Vicia faba represented by two Tunisian varieties bean (Mamdouh) and (Badii). The objective was analyze effects lead, copper cadmium their growth, chlorophyll-content carotenoids-content, as well bioaccumulation translocation...

Nitrate in serum and urine was assayed by a modification of the cadmium-reduction method; the nitrite produced was determined by diazotization of sulfanilamide and coupling to naphthylethylene diamine. After samples were deproteinized with Somogyi reagent, the nitrate was reduced by Cu-coated Cd in glycine buffer at pH 9.7 (2.5 to 3 g of Cd granules for a 4-mL reaction mixture). The reduction f...

catharantus-roseus is a medicinal and ornamental plant with growing attention toward its economical value. to determine cell viability based on trypan blue  and  mtt assay, cell suspension from callus of catharantus-roseus were treated with different concentrations of cadmium-nitratee for 1, 3 and 6 days.  also cell suspension was used to investigate the cell morphology for a period of 3 days u...

The title compound, [Cd(C(2)H(3)O(3)P)(H(2)O)](n), was obtained from vinyl-phospho-nic acid and cadmium nitrate. The vinyl groups project into the inter-lamellar space and the structure is held together via van der Waals forces. The Cd(2+) ion is six-coordinate and the geometry is best described as distorted octa-hedral, with O-Cd-O angles falling within the range 61.72 (13)-101.82 (14)°. Five ...

A sequential injection analysis (SIA) system for the simultaneous determination of nitrite, nitrate, sulphate and phenolic compounds, in wastewaters has been developed. The nitrite determination is based on the Griess-Llosvay reaction. Nitrate is previously reduced to nitrite in a copperized cadmium column and analyzed as nitrite. The sulphate determination is based on the turbidimetric determi...

in epidemiological study of esophageal carcinoma which was conducted in nov.1966 in iran, the incidence cases in the east area of mazandaran (hottan-gharagol) specifically in the torkaman region was noticeable. the frequency of the disease was gradually declined from east to west for instance in gillan (pamsar-kyasara) the incidence was low. since 1968 a joint-iran (institute of nutrition scien...

Forty domestic and imported brands of bottled water were purchased in Manitoba, Canada and examined for total dissolved solids (TDS), chloride, sulfate, nitrate-nitrogen, cadmium, lead, copper, and radioactivity. The samples showed great variation in quality, and some exceeded the Canadian Water Quality Guidelines for drinking water for TDS, chloride, and lead. Carbonation, ozonation, and type ...

Cement-based wasteforms are among the most commonly used waste disposal and site remediation options. However, concrete knowledge of the processes controlling long-term performance of the wasteforms is lacking. This research evaluates the effect of carbonation on cementitious wasteforms. Wasteforms were reacted with carbon dioxide for a prolonged period and then subjected to leaching tests. Ion...
