    Notes: Abstract  This study was conducted to determine the influence of root mucilage (RM) from Zea mays, polygalacturonic acid (PGA), and galacturonic acid (GA), on the adsorption, desorption, and exchangeability of orthophosphate (P) on a synthetic ferrihydrite in deionized water. The adsorption rate and affinity on the oxide decreased in the order P〉GA〉PGA≥RM. The results suggest that P and GA were adsorbed by ligand exchange on Fe-OH surface sites, while RM and PGA might in addition also be adsorbed by hydrogen and van der Waals bonds to the oxide surface. Whereas P and GA could be adsorbed at sites located inside the micropores of ferrihydrite aggregates, PGA and RM probably remained on the external surfaces because of their large molecular weight. The preliminary adsorption of organic compounds decreased the subsequent P adsorption. The larger decrease of P adsorption occurred when dry ferrihydrite powder was directly added to the RM/water suspension. This effect was due to the flocculation of ferrihydrite aggregates, which limited the transport of P to the adsorption sites. Preliminary adsorption of GA also decreased P adsorption, because both compounds competed for the same Fe-OH sites. The ability of the organic compounds to desorb P from the ferrihydrite was not very pronounced and decreased in the order GA〉PGA≥RM. The preliminary adsorption of organic compounds on the oxide resulted in an increase in isotopically exchangeable P in 300 min compared to the treatment without organic compounds. However, because of its higher affinity for the oxide surface, P exchangeability was not modified when P was added before the organic compounds.

    Description / Table of Contents: Résumé La cinétique de la formation et de la transformation des précipités de phosphate de calcium, obtenus en mélangeant de volumes égaux de solutions à 6×10−3 M de calcium total et/ou phosphate total est étudiée à 25°C. Les solutions de phosphate sont préajustées à un pH de 7.4. Les changements de pH et de turbidité des solutions sont suivis simultanément en fonction du temps. Les précipités sont isolés à des intervalles de temps variables et caractérisés par diverses méthodes physico-chimiques. Initialement un précipité avec un rapport molaire Ca/P de 1.5, amorphe aux rayons X et en diffraction électronique, est formé. Le spectre IR indique la présence de PO 4 3− et de HPO 4 2− . Après une période métastable, on observe la précipitation d'un matériel cristallin dans ou sur la phase amorphe. Vingt quatre heures après préparation de l'échantillon les précipités présentent surtout les caractères du phosphate octocalcique.
    Abstract: Zusammenfassung Die Kinetik der Bildung und Transformation von Calciumphosphat-Niederschlägen wurde bei 25°C untersucht. Es wurden dazu gleiche Volumen von Lösungen gemischt, bei einer Konzentration von 6×10−3M totales Calcium und/oder totales Phosphat. Die Phosphatlösungen wurden zuerst auf pH 7,4 eingestellt. Veränderungen des pH und Trübung der Lösungen wurden gleichzeitig als eine Funktion der Zeit aufgezeichnet. Niederschläge wurden in verschiedenen Zeitintervallen isoliert und mit verschiedenen physiko-chemischen Methoden charakterisiert. Am Anfang wurde ein Niederschlag mit einem molaren Ca/P-Verhältnis von 1,5, im Röntgenbild und in der Elektronendiffraktion amorph, gebildet. Infrarotspektren deuteten die Anwesenheit von PO 4 3− - und HPO 4 2− -Ionen an. Nach einer metastabilen Periode erfolgte ein Niederschlag aus kristallinem Material innerhalb oder auf der amorphen Substanz. 24 Std nach der Herstellung der Proben zeigten die Niederschläge in der Hauptsache die Charakteristiken von Octocalciumphosphat.
    Notes: Abstract The kinetics of the formation and transformation of calcium phosphate precipitates obtained by mixing equal volumes of solutions, 6×10−3 M in total calcium and/or total phosphate was investigated at 25°. The phosphate solutions were preadjusted to pH 7.4. Changes of the pH and turbidity of the solutions were followed simultaneously as a function of time. Precipitates were isolated at various time intervals and characterized by different physicochemical methods. Initially a precipitate with a molar Ca/P ratio of 1.5, amorphous to X-ray and electron diffraction was formed. IR spectra indicated the presence of PO 4 3− and HPO 4 2− ions. After a period of metastability, precipitation of a crystalline material within or upon the amorphous matter occurred. Twenty four hours after sample preparation the precipitates showed mainly the characteristics of octacalcium phosphate.

    Description / Table of Contents: Résumé Les surfaces d'émail dentaire sont confrontées avec des solutions de calcium et phosphate, qui y recirculent. Les réactions cinétiques au niveau des surfaces en calcium, phosphate, fluorure et ions hydrogène sont déterminées dans des solutions à concentrations en ions fluor constantes (0.012, 0.025, 0.050, 0.250 ou 0.500 mM/l) et/ou à pH constant (6.8, 7.0, 7.2 ou 7.4). Les vitesses de réactions des ions calcium, phosphate, hydrogène et fluorures augmentent dans les conditions suivantes: 1) augmentation de la surface d'émail, 2) augmentation des vitesses d'écoulement au niveau des surfaces, 3) augmentation du pH de la solution et 4) augmentation de la concentration en ion fluorure. Les vitesses presque proportionnelles des réactions mesurées simultanément indiquent la formation de minéraux apatitiques à la surface de l'émail pendant tout le temps de contact solide-solution.
    Abstract: Zusammenfassung Oberflächen von Zahnschmelz wurden mit konstant zirkulierenden Lösungen, welche Calcium und Phosphate enthielten, equilibriert. Die kinetischen Oberflächenreaktionen von Calcium-, Phosphat-, Fluori- und Wasserstoff-Ionen wurden in Lösungen mit konstanten Fluoridkonzentrationen (0,012, 0,025, 0,050, 0,250 oder 0,500 mM/l) und/oder konstantem pH (6,8, 7,0, 7,2 oder 7,4) bestimmt. Die Reaktionsgeschwindigkeiten dieser Ionen an der Grenze zwischen fester und flüssiger Phase erhöhten sich unter folgenden Bedingungen: 1. Vergrößerung der Schmelzoberfläche; 2. Erhöhung der Geschwindigkeit der der Oberfläche zugeführten Lösungen; 3. Erhöhung des pH der Lösung; 4. Erhöhung der Fluoridionenkonzentration in der Lösung. Die beinahe proportionalen Geschwindigkeiten der gleichzeitig gemessenen Reaktionen deuteten darauf hin, daß auf den Schmelzoberflächen während der ganzen Equilibrierungszeit Apatitminerale gebildet wurden.
    Notes: Abstract Surfaces of tooth enamel were interfaced with recirculating solutions containing calcium and phosphate. The kinetic interfacial reactions of calcium, phosphate, fluoride, and hydrogen ions were determined in solutions of constant fluoride ion concentrations (0.012, 0.025, 0.050, 0.250, or 0.500 mM/l) and /or constant pH (6.8, 7.0, 7.2, or 7.4). The rates of the calcium, phosphate, fluoride, and hydrogen ion reactions at the solid-solution interface increased under the following conditions: (1) increase of the enamel surface area; (2) increase of the rates of solution flow to the interface; (3) increase of solution pH; and (4) increase of the solution fluoride ion concentration. The nearly proportional rates of the concurrently measured reactions indicated the formation of apatitic minerals on the enamel surfaces throughout the time of solid-solution interface.

    Notes: Abstract Calvaria taken from mice aged 0, 1, 3 and 5 days were cultured for 48 h, in control medium (no added hormone), or in the presence of PTH (0.5 U/ml) or CT (50 mCl/ml). In the control group, there was a shift from net uptake of Ca and P (0- and 1-day bones) to net release (5-day bones). CT-treated bones of all ages took up Ca from the culture medium, but the percentage uptake declined with increasing age. Bones exposed to PTH released Ca and P to the culture medium, regardless of age. The changes with increasing age may be related to an increase in mineralization and other aspects of maturation in these bones.

    Notes: Abstract In 30 patients with chronic renal insufficiency (16 non-dialysed and 14 on dialysis) serum calcium, phosphate and alkaline phosphatase were determined and, in a crest biopsy specimen, morphometric determinations of bone qualities were calculated. A positive correlation was established between serum alkaline phosphatase, the osteoblast surface and the active resorption surface in both dialysed and non-dialysed patients. A positive correlation was also established between the osteoblast surface and the active resorption. In the non-dialysed patients a negative correlation was established between serum calcium and the osteoid surface.

    Notes: Abstract An active constituent of the leaves ofSolanum malacoxylon (SM) is shown to promote calcium resorption and citrate production in embryonic chick frontal bone culturedin vitro. When injected into rats, SM reduces the ATP content of liver and kidneys. This phenomenon may be related to the ability of SM to stimulate mitochondrial ATPase activity at pH 9.4. SM significantly reduces the concentration of phosphate necessary to alter the uptake of calcium and respiration of siolated mitochondria. The data suggest that SM influences calcium and phosphate metabolism by affecting ion movements into and out of mitochondria.

Les résultats de cette analyse indiquent que 50,8% des calculs sont composés d'un mélange d'oxalate de calcium et phosphate de calcium: 17,4% d'oxalate de calcium simple; 17,4% de phosphate de magnésium ammoniaqué, mélangé au phosphate de calcium et probablement aussi au carbonate de calcium: 4,4% d'acide urique et d'urate avec ou sans phosphate de calcium ou d'oxalate de calcium: 3,2% de phosphate de calcium: 1,0% de cystine et 0,2% (un cas) constitué de protéine. Sur 119 calculs, constitués d'oxalate-phosphate, les rapports de l'oxalate de calcium et du phosphate de calcium sont mesurés á l'aide des spectres infra-rouges et les rapports de 53 régions corticales de ces calculs ont été déterminés et comparés è ceux des régions nucléaires centrales. Il apparait ainsi que le noyau des calculs d'oxalate phosphate contient de plus grandes quantités de phosphate de calcium.
    Abstract: Zusammenfassung In Japan wurden die zentralen Nuclei von 500 Nierensteinen mittels Infrarotspektroskopie untersucht. Es handelte sich dabei um 421 Steine aus den oberen Harnwegen, 64 Steine aus den unteren harnwegen und 15 Prostatasteine. Die Analysen ergaben folgende Resultate: 50,8% der Steine setzten sich aus einem Gemisch von Calciumoxalat und Calciumphosphat usammen; 17,4% enthielten nur Calciumoxalate; 17,4% bestanden aus einem Gemisch von Magnesiumammoniumphosphat mit Calciumphosphat und vermutlich auch Calciumcarbonat; 4,4% enthielten Harnsäure und Urate mit oder ohne Calciumphosphat oder Calciumoxalat; 3,2% bestanden aus Calciumphosphat; 1,0% aus Cystin und 0,2% (ein Fall) aus Protein. Bei 119 Phosphatoxalatsteinen wurde das Verhältnis von Calciumoxalat zu Calciumphosphat aus den Kurven der erhaltenen Infrarotspektra bestimmt. Dieses Verhältnis wurde ebenfalls für die äußere Schicht von 53 solcher Steine berechnet und mit dem Wert der zugehörigen zentralen Nuclei verglichen. Aus diesen Resultaten geht hervor, daß die Nuclei der Phosphatoxalatsteine größere Mengen von Calciumphosphat enthalten.
    Notes: Abstract The central nuclei of 500 urinary calculi in Japan, including 421 calculi of upper urinary tracts, 64 calculi of lower urinary tracts and 15 prostatic calculi, were analysed by infrared spectroscopy. The results of analysis revealed that 50.8% of calculi were composed of mixed calcium oxalate-calcium phosphate; 17.4%, simple calcium oxalate; 17.4%, magnesium ammonium phosphate mixed with calcium phosphate, and probably also with calcium carbonate; 4.4%, uric acid and urate with or without calcium phosphate or calcium oxalate; 3.2%, calcium phosphate; 1.0%, cystine; and 0.2% (one case) were composed of protein. Of 119 oxalate-phosphate calculi the ratios of calcium oxalate to calcium phosphate were measured on the chart of infrared spectra, and also the ratios of 53 cortices taken from these calculi were measured and compared to the ratios of these central nuclei. The results showed that the nuclei of oxalate-phosphate calculi contained greater amounts of calcium phosphate.

    Paleohydrology of Andean saline lakes from sedimentological and isotopic records, Northwestern Argentina (2000)

    Notes: Abstract The paleohydrological evolution of several high altitude, saline lakes located in the southernmost Altiplano (El Peinado and San Francisco basins, Catamarca province, NW Argentina) was reconstructed applying sedimentological, geochemical and isotopic techniques. Several playa lakes from the San Francisco basin (26° 56′ S; 68° 08′ W, 3800-3900 m a.s.l.) show evidence of a recent raise in the watertable that led to modern deposition of carbonate and diatomaceous muds. A 2 m - long core from El Peinado Lake (26° 29′ 59′′ S, 68°05′ 32′′ W, 3820 m a.s.l.) consists of calcitic crusts (unit 3), overlaid by an alternation of macrophyte-rich and travertine clast- rich, laminated muds (unit 2), and topped by travertine facies (unit 1). This sedimentary sequence illustrates a paleohydrological evolution from a subaerial exposure (unit 3) to a high lake stand (unit 2), and a subsequent smaller decrease in lake level (unit 1). The δ13Corganic matterrecord also reflects the lake transgression between units 3 and 2. Although there is a general positive correlation between δ 18Ocarbonate and salinity proxies (Na, Li and B content), the large data dispersion indicates that other factors besides evaporation effects control chemical and isotopic composition of lakewater. Consequently, the oxygen isotopic composition cannot be interpreted exclusively as an indicator of salinity or evaporation ratio. The degassing of CO2 during groundwater discharge can explain the enriched δ13C values for primary carbonates precipitated. The carbon budget in these high altitude, saline lakes seems to be controlled by physical rather than biological processes.The Altiplano saline lakes contain records of environmental and climatic change, although accurate 14C dating of these lacustrine sediments is hindered by the scarcity of terrestrial organic material, and the large reservoir effects. Sedimentologic evidence, a 210Pb-based chronology, and a preliminary U/Th chronology indicate a very large reservoir effect in El Peinado, likely as a result of old groundwaters and large contributions of volcanic and geothermal 14C-free CO2 to the lake system. Alternative chronologies are needed to place these paleorecords in a reliable chronological framework. A period of increased water balance in the San Francisco basin ended at about 1660 ± 82 yr B.P. (calendar yr U/Th age), and would correlates with the humid phase between 3000 and 1800 yr B.P detected in other sites of the southern Altiplano. Both, 210Pb and preliminary U/Th dating favor a younger age for the paleohydrological changes in El Peinado. The arid period reflected by subaerial exposure and low lake levels in unit 3 would have ended with a large increase in effective moisture during the late 17th century. The increased lake level during deposition of unit 2 would represent the period between AD1650 - 1900, synchronous to the Little Ice Age. This chronological framework is coherent with other regional records that show an abrupt transition from more arid to more humid conditions in the early 17th century, and a change to modern conditions in the late 19th century. Although there are local differences, the Little Ice Age stands as a significant climatic event in the Andean Altiplano.

    Notes: Abstract  Mining of massive sulfide deposits in southwestern Spain extending back to the Copper and Bronze Ages has resulted in the pollution of the Rio Tinto fluvial-estuarine complex, the site of Columbus' departure for the New World in 1492. Additional sources of potential pollution include the large industrial complex at Huelva near the lower portion of the estuary. Extensive analysis of surface sediment samples and cores has established that there are no geographic trends in the distribution of the pollutants, which include Cu, Fe, Pb, Zn, Ti, Ba, Cr, V and Co. These data have, however, demonstrated that tidal flux within the estuary carries phosphorus and perhaps other elements from the industrial complex at Huelva to the tidal limit of the system, several kilometers upstream from the discharge site. Radiometric analysis of short cores shows that sedimentation rates over at least the past couple of centuries have been about 0.3 cm/year. These data and that from a single deep core demonstrate that the estuary was polluted from mining activity long before the large-scale operations began in the late nineteenth century.

    Description / Table of Contents: Résumé Les énergies de déplacement des ions F−, OH− et O2− dans la maille réticulaire des apatites ont été calculées en utilisant un modèle cristallin de Born. Une attention particulière a été apportée au déplacement parallèle de l'axe c par un mécanisme de lacune. Contrairement à la plupart des cristaux ioniques, la barrière opposée au déplacement est électrostatique plutôt que répulsive. L'énergie de déplacement d'un cristal donné est la plus faible pour F−, intermédiaire pour O2−, et la plus élevée pour OH−.
    Abstract: Zusammenfassung Die Bewegungsenergien von F−, OH− und O2−-Ionen im Apatitgitter wurden berechnet, indem ein Born-Modell des Kristalles verwendent wurde. Die Untersuchung wurde auf die Migration beschränkt, welche durch einen Vakanzmechanismus parallel zur C-Achse verläuft. Im Gegensatz zu den meisten Ionenkristallen hat die Migrationsbegrenzung eher einen elektrostatischen als einen abstoßenden Charakter. Es wurde festgestellt, daß die Migrationsenergie in einem Kristall am kleinsten für F−, dazwischen liegend für O2− und am größten für OH− ist.
    Notes: Abstract The energies of motion of F−, OH− and O2− ions in the apatite lattice have been calculated using a Born model of the crystal. Attention was confined to migration parallel to the c-axis by a vacancy mechanism. In contrast to most ionic crystals the barrier to migration is electrostatic rather than repulsive in character. It is found that the migration energy in a given crystal is least for F−, intermediate for O2− and largest for OH−.
