This study examines Pennsylvanian shales in Indiana as a potential source of selected critical elements: rare earth elements (REE), vanadium (V), zinc (Zn), arsenic (As), and cadmium (Cd). Widespread, organic-matter-rich marine Desmoinesian black are the main target, but other discontinuous shale horizons were also sampled 11 locations. In total, 39 samples analyzed this study. The early mature...

BACKGROUND Deficiency of macro and micro-minerals in the ration of dairy cows adversely affects growth, milk production and reproduction efficiency. It is essential to examine mineral concentrations in feeds offered to dairy cows in practical farms. METHODS Two villages from each taluka were selected at random for taking representative samples of feeds, forages and hair. Within the village, h...

This study aims to characterize salmonid manures and to determine their potential use in agricultural soils. Sampling was carried out below salmon and trout cages in farms located in lakes and in the sea in the South of Chile during 2002-2003. Manure was analyzed for macronutrients, micronutrients and heavy metals. Results showed a high variability between samples and differences between sea an...

Ag/Zn and Ag particles have been successfully produced from electrolytes simulating zinc process solutions containing a high concentration (65 g/L) negligible silver (0.5–50 ppm) using facile sustainable electrodeposition-redox replacement (EDRR) method. Results show that the particle size chemical composition of deposited can be readily controlled by varying operating parameters such as time a...

BACKGROUND Hoof lesions are very common among sows and have been associated with lameness, early removal and compromised welfare and productivity. Although housing conditions and management can have an external effect on hoof health status, the role of trace mineral intake is vital in developing hoof structure and integrity. Therefore, the objective of this study was to investigate the effect o...

A transformer fire occurred in a state office building in Binghamton, NY on February 5, 1981. Particulates from inside surfaces of ceiling panels on 16 of the 17 floors had concentrations of polychlorinated dibenzofurans (PCDFs) ranging from less than 1 part per million (ppm) to 1200 ppm while polychlorinated biphenyl (PCB) concentrations varied from 28 ppm to 23,000 ppm. In spite of the wide v...

in order to investigate the impact of foliar zn application in reducing the negative effects of water stress on bean growth and yield, a field experiment was carried out in the research field of ilam university in 2011. the experiment was arranged in split factorial based on a randomized complete block design with three replications. the experimental factors were water stress including water wi...
