Abstract:

The copper uptake and toxicity of young and market-size tilapia, Oreochromis niloticus, exposed to copper sulP'hate were investigated. A series of preliminary experiments were conducted to provide requisite information for the final experiment. Preliminary experiments established uptake by the culture systems, feed and/or faeces, and. the impact of fish nutritional state on uptake. Other experiments established the median lethal concentration of copper to this species, an extrapolated minimal lethal concentration, and the optimum exposure duration and concentration for copper uptake.

Abstract:

Copper and Zn deficiencies of crops have been reported in various parts of the world. To prevent these deficiencies sulfate forms of Cu and Zn are generally used. In addition, Cu and Zn also are contributed to soils by manures, pesticides, and waste materials such as sewage sludge. An insufficient supply of Cu or Zn may reduce crop yield; whereas, excess Cu or Zn may be detrimental to both plant and animals. The field phase of this research was conducted on a Davidson silty clay to evaluate corn response to high levels of CuSO₄ and ZnSO₄ applications up to 338 kg Cu and 830 kg Zn ha⁻¹. The r

Abstract:

Wastewater has become a vital new supply for irrigation; however, concerns are mounting about environmental and health hazards related to heavy metals present in wastewater. Experiments were conducted to evaluate wheat ( Triticum aestivum L.) and buckwheat (Fagopyrum esculentum L.) uptake of copper (Cu) and zinc (Zn).<br>Some 15 plants per pot were allowed to establish themselves in the greenhouse for 4 and 6 weeks for buckwheat and wheat, respectively. Plants were then transferred to one of two growth chambers differing in the vapor pressure deficit (VPD), creating conditions for two d

Abstract:

For trace elements, such as copper (Cu) and zinc (Zn), the bioavailability of these elements, Cu and Zn, in biosolids is important because both are essential elements and both are potential contaminants when biosolids are land applied. A greenhouse study was conducted in factorial experiment based on a completely randomized design (CRD) with four replications on a soil treated with four rates of Cu (0, 50, 100, and 150 mg/kg) and four rates of Zn (0, 150, 300, and 450 mg/kg) on celery plants to investigate the distribution and mobility of these elements as well as growth and antioxidant change

Abstract:

Prion protein (PrPC) is a cell surface glycoprotein, anchored by the GPI to the cell membrane. It seems to be involved in some neurodegenerative diseases, but its physiological function is still undefined. Many cellular functions were proposed as PrPC roles, such as the modulation of several signal transduction pathways known to promote cellular survival and the protection against oxidative stress. Nevertheless, the main hypothesis on PrPC role is in copper homeostasis. Copper is an essential micronutrient (EMN) and all EMNs (vitamins and metals) are present in bodies and foods in micro

Abstract:

Copper oxide nanoparticles (NPs) are used in an expanding range of industries including a potential for agricultural applications as a fungicide. Accidental spills or misapplication of CuO NPs may lead to soil contamination. Plant roots exude a wide range of organic chemicals for bioprotection and to enhance bioavailability of nutrients. Many of these chemicals are metal chelators that may increase the solubility of CuO NPs, thus enhancing the impact of these NPs on plants. This work was directed towards understanding which plant exudates force increased solubility of CuO NPs and to determine

Abstract:

Polluted stormwater, if not treated, can compromise water quality throughout our hydrologic cycle, adversely affecting aquatic ecosystems. Common stormwater pollutants, copper and zinc, have been identified as primary toxicants in multiple freshwater and marine environments. For small-scale generators, stormwater management can be cumbersome and implementation of common BMPs impractical thus catch basins are popular though not the most environmentally conscious and sustainable option. This study aims to characterize the potential of a mobile media filter operation for the treatment and on-site

Abstract:

Iron and copper are essential for nearly all known organisms as they are utilised in a wide variety of enzymatic processes. In both prokaryotes and eukaryotes, the metabolism of both metals is often intimately and inseparably linked. The host environment is limiting for Fe and Cu ions and immune-responsive mechanisms have been identified that further reduce available iron upon infection. Therefore, for a pathogen to be successful it must possess mechanisms to acquire copper and especially iron from this hostile environment. Mechanisms that facilitate iron and copper uptake have been described

This study was designed to examine the influence of Cu deficiency on the binding, uptake, and degradation of apolipoprotein E-free high density lipoproteins (apo E-free HDL) in cultured rat hepatic parenchymal cells. The binding of apo E-free HDL during time course studies was slightly but significantly increased in cells derived from Cu-deficient rats. In saturation studies, the amount of surface-bound apo E-free HDL appeared to be saturable, although no difference was observed between Cu-deficient and adequate animals.

Abstract:

Our central nervous system employs strict regulation of the trace element copper, and dysregulation is implicated in the neuropathology of many neurodegenerative and neurocognitive diseases. Recent interest into the contribution of copper dysregulation to neurological disease has exposed our limited understanding of neuronal copper homeostasis. For instance, known uptake mechanisms do not completely account for cellular copper concentrations, suggesting alternate mechanisms remain to be found.

Copper (Cu) is an essential micronutrient for plants and many microorganisms, playing a key role in electron transport during photosynthesis, lignin formation and cell wall metabolism. However, when Cu is present at elevated concentrations it can cause toxicity with impacts on the growth, reproduction and survival of aquatic and terrestrial organisms. The biogeochemical cycle of Cu in aquatic and terrestrial environments can be influenced by numerous biological (e.g. root rhizosphere) and physicochemical (e.g. redox, pH) properties.
