    Nickel-sensitive patients with vesicular hand eczema: oral challenge with a diet naturally high in nickel (1990)

    Notes: Oral challenge with nickel sulphate indicated that vesicular hand eczema in nickel-sensitive patients may be exacerbated by nickel occurring naturally in the diet. Twelve nickel-sensitive females with vesicular hand eczema were challenged with a supplementary high nickel diet for 4 days in a single-blind cross-over study. The diet had about five times the average nickel content of the daily Danish diet. An aggravation of the hand eczema was observed in six out of 12 patients on day 4 after the start of the challenge. By day 11, the hand eczema was worse in 10 out of 12 patients, and remained unchanged in two.

    Notes: [Auszug] Most of the tetraalkyl lead in petrol is decomposed to inorganic lead during the combustion in the automobile engine. Evaporation and incomplete combustion of leaded petrol, however, cause atmospheric pollution by organolead compounds. The 24 h mean value of volatile tetraalkyl lead is about 0.25 ...

    Notes: [Auszug] Intranasal species of trombiculids were first found by one of us while searching for pulmonary mites in rodents of Central Africa (Ruanda-Urundi and the Belgian Congo)1. A total of nine such species in four genera/subgenera (some of which are as yet undescribed), mostly related to Schoutedenichia ...

    Lead concentration in single hairs as a monitor of occupational lead exposure (1978)
    Springer
    International archives of occupational and environmental health 42 (1978), S. 69-81 
    Details
    ISSN: 1432-1246
    Keywords: Lead in hair ; Occupational lead exposure ; Permissible limits ; Screening methods

    Topics: Medicine
    Notes: Summary A rapid method for the analysis of 1-cm segments of single hairs has been developed. The hairs are washed with Freon TF in an ultrasonic bath and analyzed by electrothermal atomic absorption spectrometry. Due to diffusion of exogenous lead into the hairs the lead concentration increases along the hair shaft. Thus only the first 1-cm segment close to the hair root is used. In a reference population of 44 males no association was found between the hair lead concentration and age of the individual. Dark hairs tended to contain more lead than white hairs, but such difference was not apparent in occupationally exposed males. During four weeks blood and urine samples were collected from 87 males with occupational lead exposure, and hairs which had grown 1 cm during this period were then sampled and analyzed. The lead concentration in the first 1-cm segment of the hairs correlated significantly with the average lead concentration in blood and in urine, and δ-aminolevulinate in urine. Hair lead increases exponentially with increasing blood lead. A permissible limit of 60µg lead/100 ml blood corresponds to about 70µg lead/g hair or 3ng lead/cm hair. The analysis of single hairs for lead is recommended as a screening method.

    Seawater-sediment-basalt interactions: stable isotope (H, O) and elemental fluxes within the Ordovician volcano-sedimentary sequence of Erquy (Brittany, France) (1995)

    Notes: Abstract The Ordovician volcano-sedimentary succession of Erquy (northern Brittany) is made of immature sediments thermally metamorphosed at the contact of intruding basic sills. Pillow lavas constitute the upper part of the sequence. The trace element geochemistry of sills and pillow lavas suggests that they were derived from a tholeiitic source located beneath a passive margin. This volcanic sequence was metamorphosed under low to moderate greenschist facies conditions. In this study the direction and amplitude of chemical and isotopic fluxes in the basalt-sediment-water system were established and the oxygen and hydrogen isotope compositions of the aqueous fluid that reacted with the volcanic rocks were characterized. Cationic thermometry on chlorites and isotopic thermometry on plagioclase-chlorite pairs indicate closure metamorphic temperatures in the range 200–250°C for the basaltic sills. Stable isotope compositions of iron-rich chlorites (δ18O-5.5‰; δD from-60 to-50‰) and plagioclases (δ18O from +9 to +10‰) reveal that the source of the fluid was certainly seawater. The δ18O variations within the sills are strongly correlated with the rate of progress of the main metamorphic reaction:clinopyroxene+plagioclase+ilmenite → chlorite+albite+epidote+quartz+sphene that produced major element mobility at the scale of the volcanosedimentary sequence. Calculation of elemental fluxes by mass balance combined with oxygen isotopic compositions of basalts shows that the highest water-rock ratios (≥1) were at sill-sediment boundaries and within pillow lavas at the top of the pile. The volcanosedimentary sequence of Erquy was a net sink for Na and a source for Ca. No Mg uptake could be detected whereas the hydrothermal alteration of the sediments released Fe, Si, and K trapped by the volcanic rocks. The δ18O value of the fluid reacting with sills appears to have shifted no more than +4‰ after percolation at low temperature through immature sediments (δ18O≈12‰). The Erquy volcano-sedimentary sequence represents a marine hydrothermal system dominated by low-temperature exchange which allowed a general 18O-enrichment of the volcanic rocks and a 18O-depletion of sediments.
