The elements Fe, Cu, Mn, Zn, Cr, Ni, Pb and Cd were determined in the meat and skin of fish by Atomic Absorption Spectroscopy (AAS). The fish were grown in treated wastewater, Zayanderood river, and fisheries of Flavarjan and Babolsar. Arsenic and mercury in the samples were analyzed by Inductively Coupled Plasma Emission Spectroscopy and Cold Vapor AAS, respectively. The concentration of t...

Internal friction and ultrasonic attenuation peaks associated with diffusionless phase transformations in alloys, such as thermoelastic martensites and others, were reviewed. They were discussed from the stand point of (1) Understanding the mechanism of the phase transformations and (2) Developing new alloy materials of high damping capacity for application to noise and vibration abatement. Pha...

A field study was conducted to assess the agronomical performance of eggplant (Solanum melongena cv. Pusa Purple Long Hybrid-F1) grown in sewage sludge amended soil in rainy and summer seasons during two consecutive years 2012 and 2013. The results showed that sewage sludge significantly (P < 0.05/P < 0.01) increased the Organic Carbon (OC), sodium (Na + ), potassium (K + ), calcium (Ca 2+ ), m...

1. Sheep fitted with a rumen fistula and either a re-entrant cannula at the proximal duodenum or a re-entrant cannula at the terminal ileum were given twice daily 480-520 g dry matter as fresh perennial ryegrass, or white or red clover. Flows of digesta were corrected to 100% recovery of chronic oxide. 2. The quantities (g/24 h) of zince and cobalt leaving the stomach were significantly greater...

the increasing need for water in the arid areas of the world has resulted in the emergence of wastewater application for agriculture and landscape. using treated wastewater in agricultural irrigation can provide more adequate supply of high quality water for human consumption, but their heavy metal applications effect must be regulated to ensure no physiological problems for both the plant and ...

BACKGROUND Previous studies indicated that the iron (Fe)/manganese (Mn) ratio in forage of sheep was significantly higher on scrapie-afflicted farms than on farms in other scrapie categories. This study was conducted to examine whether Fe and Mn in forage of sheep varied in general according to the scrapie status of different areas in the country. Copper (Cu) and zinc (Zn) were also included be...

The aim of this trial was to study the concentration of zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), selenium (Se), cobalt (Co) and iodine (I) in milk and blood serum of lactating donkeys, taking into account the effects of lactation stage and dietary supplementation with trace elements. During a 3-month period, 16 clinically healthy lactating donkeys (Martina-Franca-derived population), ...

The technique of DGT (diffusive gradients in thin films) using three diffusive gel thicknesses was applied to estimate the mobility and bioavailability of heavy metals in sediments and porewater of Lake Taihu, China. The DGT results showed significantly positive correlations between Co, Pb, Cd and Mn, and Ni and Fe concentrations in porewater. Cu and Zn showed a significantly negative correlati...
