Evaluar el crecimiento de Helianthus annuus L. Directory of Open Access Journals Sweden. Contenido de plomo y cadmio en aceites de girasol. These elements are toxicological importance and the sunflower oil is widely consumed in Spain. Samples were mineralized with nitric acid and vanadium pentoxide as catalyst, and ana lyzed using electrothermal atomization atomic absorption spectroscopy. The temperature-time programme for the graphite furnace was optimized for each element, and the accuracy, precision, sensitivity and detection limit of the method were evaluated.

Concentrations of lead ranged from not detectable to The data obtained dl not excessive and similar to those mentioned by other authors; however, one sample of the total analyzed surpassed the limit of 0. Las concentraciones de plomo han oscilado entre no detectables y Full Text Available Objetivo.

Asimismo, variables como la zona de residencia, el sexo, la edad y la ingesta de comida enlatada no influyen en los niveles de plomo y cromo. Las medianas de las con Niveles de plomo y cadmio en agua farmacoocinetica y lapas Patella vulgata L.

En el presente estudio se han recogido muestras de agua marina y de lapas Patella vulgata L. El objetivo de este estudio fue evaluar la capacidad extractora de Plomo Pb y Cadmio Cd del quelite Amaranthus hybridus L. En el primero se adicionaron tres cantidades de micorrizas 0, 2. To determine the concentration of lead Pb, cadmium Cd, and chromium Cr and establish the possible association of these heavy metals with some sociodemographic factors. A representative sample of one hundred dental students from the National Autonomous University of Mexico living in Mexico City participated in this study.

Unstimulated human whole saliva samples were analyzed by Atomic Absorption Spectroscopy. Concentrations of Pb, Cd, and Cr were higher than those reported elsewhere: No association was found farmaacocinetica the variables studied age, sex, geographic area and canned food consumption.

Heavy metal cadmium and lead content has been determined by means of differential pulse anodic stripping voltammetry in both limpet and seaweed tissues, as well as in seawater. The obtained results have shown the main heavy metal content in limpet soft tissues with respect to shell, farmacocineticx maximum concentrations of 3 ppm limpet shell for lead, whereas the highest content for cadmium was identified in seaweed samples 1.

The statistical study revealed the existence of a clear correlation between cadmium and lead concentrations in seaweed samples. En el presente trabajo se han recogido muestras de lapa Patella vulgata L.

The Cadmio XML healthcare record. The management of clinical data is a complex task. Patient related information reported in patient folders is a set of heterogeneous and structured data accessed by different users having different goals in local or farmacocinetoca networks. XML language provides a mechanism for describing, manipulating, and visualising structured data in web-based applications.

XML ensures that the structured data is managed in a uniform and transparent manner independently from the applications and their providers guaranteeing some interoperability. Extracting data from the healthcare record and structuring them according to XML makes the data available through browsers. Las muestras de sangre venosa fueron recolectadas en tubos de vidrio, libres de metales, con heparina.

Levels of cadmium, lead, cooper and zinc in vegetables cultivated in a highly urbanized area of La Havana city, Cuba; Niveles de cadmioplomocobre y zinc en hortalizas cultivadas en una zona altamente urbanizada de la ciudad de la Habana, Cuba. In this paper we report levels of Cu, Pb, Cd and Zn in soils and vegetables grown in a highly urbanized area of La Havana city.

We studied 17 farms dedicated to urban agriculture in an area of two kilometers around the landfill -Calle during and For the study, samples of the soil and all the vegetables ready to harvest were taken from the farms.

The heavy metals Cu, Zn, Pb and Cd were analyzed by atomic absorption spectrophotometry. The levels of heavy metals in agricultural soils varied in the following ranges: The results indicate the need for strict crop monitoring in the area. Disclaimer What is zinc and what does it do? The detection limits determined for Cd, Pb and Zn using a synthetic water matrix 2. The methodology by TS-FF-AAS was validated by determination of Cd, Pb and Zn in certified reference materials of water and marine sediment, and the t-test for differences between means was applied.

Some early research suggests that zinc supplementation increases sperm count, testosterone levels, and pregnancy rates in infertile men with low testosterone levels. Other research suggests that taking zinc can improve sperm shape in men with moderate enlargement of a Full Text Available The present study aims to determine the presence of cadmium and lead heavy metals in the Chone River estuary; Ecuador, during June to Septembersix water samples and five soil samples were obtained at six sites, with two replications per site giving a total of 66 samples.

The analysis was performed according to the protocol of Merck-Millipore Kit for cadmium and lead. Cadmium concentrations in the water were higher at the Farmacocibetica site 0.

The level of cadmium in the sediment showed greater accumulation 0. The sites with higher level of lead were P5 and P6 0. Full Text Available The Cd concentration famracocinetica the seed of crops depends on various soil factors including parent farmacocinetca, texture, pH, soil redox, and salinity. Cadmium accumulation also varies among crop species and cultivars within a species. Cadmium and Zn may have either an antagonistic or a synergistic effect on plant uptake that can be influenced by the soil Farkacocinetica and Zn concentrations.

Studies were conducted at five North Dakota locations representing different soil series during and In Experiment 1, nine crops common in North Dakota were grown with and without the addition of 25 kg ha-1 Zn fertilizer.

Among crops evaluated, the greatest seed Cd accumulation occurred in flax Linum usitatissimum L. In Experiment 2, two durum wheats and one flax cultivar were grown under three Zn treatments of 0, 5, and 25 kg ha In Experiment again flax had the higher seed Cd level compared with the two durum varieties. Based on the results from both studies, addition fadmacocinetica Zn fertilizer did not consistently reduce seed Cd content, and even when statistically significant, the level of reduction was small and not likely to impact marketability of Cd accumulating crops such as flax, sunflower, soybean, and durum.

Spanish standards on the subject are also reviewed. En casos graves suele requerirse de dosis repetidas. Se tomaron muestras de suelos no disturbadas en cilindros de PVC, arsenio cuales, luego de aplicaciones fraccionadas de cadmio con dosis de 0, 50, y ppm, se incubaron a capacidad de campo durante cuatro meses.

Full Text Available Pyro-refining is one of the techniques used in recycling lead. Two significant stages in theprocess are decopperization and desilverization, farmaacocinetica are traditionally arrsenico by addingpowdered Sulfer and Zinc at the surface of the lead bath and then mixing it farmacocinetiva a propeller.

The efficiency of this process has been improved by using a submerged lance to injectthe reactants into the interior of the lead bath, but the hydrodynamics of this new methodhas not yet been studied until now. The aim of this study was to refine the techniquesfor injecting particles into lead baths by performing mathematical simulations using theCOMSOL 3.

Residence and mixing times were produced for different injectionvelocities, and the simulation results for residence times were validated by experimentaldata obtained in the laboratory. To evaluate traditional acidic curing as a preventive method for reducing lead content of glazed ceramic ware. Farmaoccinetica lead content of the vinegar washing diminished proportionally with the number of washings, although it remained highly above the permissible levels of this metal 2.

Traditional acidic curing of glazed ceramic ware is not a useful preventive measure for reducing lead exposure. Such a structure has special needs and the characteristics of its medical folders are very different from any other folder.

Moreover, it must keep track of the clinician subjective considerations about the patient psychic state and his situation in regard of the law. So, we had to redesign some of the features of the existing CADMIO application, to accommodate such highly not structured data into objects easily arsejico by an informative system. The objectives we hope to achieve were mainly two:
