To evaluate the effectiveness of various organic or inorganic fertilizers on the growth and physiology of Chrysanthemum morifolium (an important ornamental plant) the current research was conducted in a completely randomized design. Seedlings were treated with vermicompost (0 and 40% w/w of soil), nano-chelated zinc (nano-Zn) (0 and 0.1% (w/v)) or ZnSO4 (0 and 0.2% (w/v). Sprays of nano-Zn or Z...

Assessing the availability of dietary micro-minerals is a major challenge in mineral nutrition fish species. The present article aims to describe systematic approach combining different methodologies assess zinc (Zn) Atlantic salmon (Salmo salar). Considering that several Zn chemical species can be an feed, it was hypothesised influenced by feed. Thus, this study, first protocol about how extra...

Groundwater and surface water were collected using trace metal clean techniques from the upper glacial aquifer of West Neck Bay (Shelter Island) in eastern Long Island, NY, during the late spring and summer of 1999. The collection sites on Shelter Island are located in an area that is primarily residential and believed to have uncontaminated groundwater. Ultrafiltration was used to size-fractio...

The aim of this investigation was to determine the occurrence of As, Cu, Cr and Zn in the soil at an abandoned wood preservation unit and to examine some possible extractants for the contaminants in the soil. The mean As content of the contaminated surface soils (0-10 cm) was 186 mg kg(-1), where as the mean concentrations of Cu, Cr and Zn in soils from the contaminated area were 26, 29 and 91 ...

In this research work, the original 45S5 bioactive glass was modified by introducing zinc and/or strontium oxide (6 mol%) in place of calcium oxide. Sr was added for its ability to stimulate bone formation and Zn for its role in bone metabolism, antibacterial properties, and anti-inflammatory effect. The glasses were produced by means of melting and quenching process. SEM and XRD analyses evide...

Platinum mines produce large amounts of inorganic tailings containing high levels metals which are disposed on disposal facilities (TDFs) and there is no information available their possible effects the surrounding terrestrial environment. The aim this study was to do an earthworm bioassay soils along a gradient from TDF over period 28 days in terms growth, reproduction metal accumulation. Afte...

The pyrolytic carbon of polymer adsorbent resin (SAP) is used as a waste source, which can be porous network via pyrolysis to remove surface sodium carbonate and other substances. In this paper, ZnFe2O4/nitrogen-doped composite was prepared using the template method. Through high-temperature carbonization crystallization inorganic elements, morphology showed uniform load characteristics. This w...

The effects of mine drainage on 2 bacterial processes were examined in Rocky Mountain streams affected by mine drainage. Thymidine incorporation into bacterial DNA was measured as an index of bacterial production, and nitrification was examined because it is sensitive to a variety of stressors. These processes, as well as pH, concentration of dissolved Zn, and deposition rate of metal oxides, a...
