Heavy metals accumulations at Dam basin originated from mining sites through erosion and water transportations find themselves in a soil, bodies plants contaminated soil their roots those that settle on the get to animals organs. This study explored concentration of these heavy levels present rice grown vicinity Dam, which were compared with [1] maximum recommendation safer for human ingesting....

Heavy metals in outdoor and indoor airborne particulate matter (PM) and dust in different residential built environmentsat two rural and one urban site in Pakistan were analysed. An eight stage non-viable impactor (Thermo Fisher Scientific Inc., USA) loaded with EMP 2000 glass microfiber filter papers (Whatman, England) was used to collect airborne PM.The indoordust samples (settled dust) were ...

The genus Alyssum (Brassicaceae) contains Ni hyperaccumulators (50), many of which can achieve 30 g kg(-1) Ni in dry leaf. Some Alyssum hyperaccumulators are viable candidates for commercial Ni phytoremediation and phytomining technologies. It is not known whether these species secrete organic and/or amino acids into the rhizosphere to solubilize Ni, or can make use of such acids within the soi...

The present study investigates the accumulation of vanadium, iron, and nickel in different depths of soil in collection sites of oil sludge, in Masjed Soleyman Oil and Gas Exploitation Company, located in Choob Sorkh Region. To conduct the research, four sampling points have been selected at the mentioned site, with one sampling point chosen outside the site, as the clean area. Soil sampling ha...

Concentrations of seven heavy metals (Cd, Cr, Cu, Hg, Ni, Pb, and Zn) and one metalloid (As) as well as various parameters (pH, organic carbon, granulometric analysis and cation exchange capacity) were analyzed in 77 soil samples collected in the mining areas of La Zanja and Colquirrumi (Department of Cajamarca) and Julcani (Department of Huancavelica). Our study proposed geochemical baseline v...

metals sorption on solid phase from solution is one of the most important chemical processes controlling their bioavailability in soils. nickel (ni) sorption characteristics in 20 calcareous soils of iran were investigated in a range from 5.87 to 751.23 mgl-1 ni concentration in solution using sorption isotherms. ni sorption isotherm exhibited strong nonlinear behavior for all soils. the result...

Assessment of the ecological quality of theMinho estuary (Northwest Iberian Peninsula) based on metal concentrations in sediments and in Corbicula fluminea The concentrations of metals (Cd, Cr, Cu, Fe, Ni, Pb and Zn) in sediments and the soft tissues of Corbicula fluminea from the Minho estuary (Northwest Iberian Peninsula) were determined to assess the spatial variation of metal bioavailabilit...

The present study evaluated and compared the effects of SRI 63-441, a potent platelet activating factor antagonist, superoxide dismutase (SOD), an oxygen free radical scavenger, and ibuprofen, a cyclooxygenase inhibitor on hepatic function after 90 minutes of warm ischemia. After warm ischemia, livers were harvested and underwent 90 minutes of warm, oxygenated, sanguinous perfusion on an isolat...

The objective of this study was to investigate bioaccumulation of nickel (Ni) and vanadium (V) in clams living in different salinity regimes along the Saudi coast of the Arabian Gulf. Several hundred clam (Meretrix meretrix), sediment, and seawater samples were collected from 12 locations. Concentrations of Ni and V were determined in these samples using an inductively coupled argon plasma anal...

Angus and Angus x Limousin cross steers (n = 182; initial BW = 309 +/- 27.8 kg) were used to evaluate the influence of an estradiol-trenbolone acetate implant (containing 24 mg of estradiol and 125 mg of trenbolone acetate) on production efficiency and carcass traits when administered at specific stages of growth. Treatments were 1) control, no implant (NI); 2) early implant (EI) on d 1 (BW = 3...
