Analysis of the total copper and zinc content of four species of talitrid amphipods, Orchestia gammarellus, O. mediterranea, Talitrus saltator and Talorchestia deshayesii throughout a complete spring/neap tidal cycle failed to reveal any significant effects of moulting upon body copper or zinc in any species. Moulting was synchronized to the lunar cycle only in T. saltator, taking place 5–7 days prior to a new moon. The fact that no significant changes in body metal concentrations took place with the moult cycle is discussed in relation to the use of talitrid amphipods in copper and zinc biomonitoring programmes.

Important biogenic elements of plants are zinc and copper, which come into them from the soil in the form of cations. Plants selectively absorb the elements they need in accordance with physiological and biochemical needs, as well as the characteristics of their vegetation. Copper and zinc are part of the enzymes that are necessary for the normal course of many biochemical reactions. Lack or excess of any chemical element causes a violation of the normal course of biochemical and physiological processes in plants. The paper presents the results of the study of zinc and copper content in the soil, as well as in the above-ground and underground organs of the studied plant object. Quantitative determination of zinc and copper was carried out on an atomic absorption spectrometer. As an object of study, a flower plant of the Gentian family (lat. Gentianáceae), genus Eustoma (lat. Eustoma), grade Aube Pink Picotee. Vegetation experiments were carried out on the basis of LLC "Greenhouse "Iceberg". According to the data, the content of zinc and copper in the organs of the studied plant decreases in a number of root – aboveground part – flower. In different periods of vegetation there is a different accumulation of copper and zinc in the aboveground and underground organs. The root of this plant performs a barrier function, blocking the flow of copper into the plant from the soil at 27 weeks of development. In this case, the zinc content in the root of the plant during this period increases significantly, but this figure in the above-ground part of the plant varies slightly. According to the calculated average value of the biological absorption coefficient, it can be seen that the accumulation of zinc in the plant occurs to a greater extent than the accumulation of copper.

ABSTRACT Hydrologic changes modify microbial community structure and ecosystem functions, especially in wetland systems. Here, we present 24 metagenomes from a coastal freshwater wetland experiment in which we manipulated hydrologic conditions and plant presence. These wetland soil metagenomes will deepen our understanding of how hydrology and vegetation influence microbial functional diversity.

BackgroundCopper is frequently used as an algicide, and copper ion generators such as the Aquascape IonGen claim to be safe for use in systems containing fish. In 2012, a die-off of koi (Cyprinus carpio) in a pond in Raleigh, North Carolina, occurred after the IonGen was added to the system.MethodsPhysical and postmortem examinations suggested that heavy metal toxicity was the likely cause of morbidity and mortality. This was supported by a heavy metal screening of the owners’ pond. Additional experiments were performed to determine if the IonGen produced toxic levels of copper and zinc.ResultsThe tank containing the IonGen had higher concentrations of copper and zinc, and copper levels exceeded those associated with toxicity in both hard and soft water.ConclusionThe results of this study indicate that ion generators might not be safe for fish, and copper should only be used as an algicide if concentrations are closely monitored.

Copper And Zinc

The extracellular haemoglobins of Lumbricus and Tylorrhynchus contain 50 and 61 tightly bound calcium atoms per molecule, respectively. In addition, they contain one to four tightly bound copper and zinc atoms. Although the role of the latter is unknown, that of calcium is probably structural, assisting in the maintenance of the native hexagonal bilayer structure.

An investigation was carried out to develop finger millet based nutritious cookies and their sensory and nutritional evaluation was carried out. Two types of cookies were prepared by replacing 30 and 50 % of refined flour with finger millet. Both types of cookies were found acceptable. Addition of finger millet flour increased the total mineral, fiber, calcium, iron, phosphorus, copper, and zinc content of cookies. Finger millet flour can be successfully substituted upto 50 % level for the development of nutritious cookies.

Abstract Field experiments determined copper and zinc content and accumulation in yellow lupine roots, stems, leaves, flowers, pods and seeds. The test factors included development stages (BBCH 65 and BBCH 90) at which harvest was performed as well as nitrogen doses (0, 30, and 120 kg·ha−1) introduced to the soil prior to sowing. A higher copper content (by an average of 20.9%) and zinc content (by 53.7%) were obtained in the whole mass of lupine harvested at the flowering stage compared to that at the full maturity stage. Yellow lupine fertilised with 120 kg N·ha−1 contained and took up more copper and zinc than both lupine cultivated without nitrogen fertilization and fertilised with 30 kg N·ha−1. The application of different nitrogen doses had no significant effect on the contents of the micronutrients in the seeds of the test plant. The amount of copper and zinc accumulated in the seeds was the largest following the application of 120 kg N·ha−1. Lupine accumulated the largest amounts of both elements in the leaves irrespective of the development stage at which the harvest was carried out. The bioaccumulation factor for copper and zinc was higher in the lupine harvested at the flowering stage than in the lupine harvested at full maturity, but it was not significantly determined by the applied nitrogen fertilization. The values of translocation coefficient for the tested heavy metals, usually higher than 1, indicate significant potential for their accumulation in yellow lupine biomass. Under conditions of an increased zinc content in the soil, lupine green matter harvested at the flowering stage contained an above-standard amount of this heavy metal and could not be used for animal feed.
