  1. 1. Atmospheric Corrosion of Lead. The Influence of Organic acid Vapours and Inorganic Air Pollutants. A contribution Towards Understanding the Environmental Degradation of Historic Organ Pipes

    Author : Annika Niklasson; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organ pipe; formic acid; Atmospheric corrosion; lead formate; lead acetate; NaCl; lead; acetic acid;

    Abstract : This thesis presents different perspectives on the atmospheric corrosion of lead, aiming at a better understanding of the environmental degradation of historical organ pipes. Corroded organ pipes from the field have been analyzed and the environment inside the organ wind system has been mapped. READ MORE

  2. 2. Lead in blood. ICP-MS studies of lead in plasma, blood and erythrocyte proteins

    University dissertation from Department of Occupational and Environmental Medicine, Lund University

    Author : Ingvar A Bergdahl; [1997]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; distribution; plasma; blood; erythrocytes; lead-binding prtoeins; delta-aminlevulinic acid dehydratase; inductively coupled plasma mass spectrometry; ALAD; arbetsmiljömedicin; Occupational health; industrial medicine; Lead; toxicity; ICP-MS; Yrkesmedicin;

    Abstract : An inductively coupled plasma mass spectrometry (ICP-MS) method for the determination of lead in blood plasma has been developed. The detection limit was below 0.1 microgram/liter, and the precision 5%. There was no significant difference between levels in plasma and serum. READ MORE

  3. 3. The fate of airborne lead pollution in boreal forest soils

    University dissertation from Umeå : Ekologi, miljö och geovetenskap

    Author : Jonatan Klaminder; Ingemar Renberg; John G. Farmer; [2005]
    Keywords : Air pollution; lead; lead isotopes; peat; forest soil; forest plants;

    Abstract : Lead has a more than three-millennia-long pollution history in Europe. Metal production, burning of coal and use of leaded petrol resulted in a significant pollution of the atmosphere. As a consequence of atmospheric fallout, the Swedish boreal forest is strongly contaminated by airborne lead pollution. READ MORE

  4. 4. Atmospheric Corrosion of Historic Lead Organ Pipes

    University dissertation from Umeå : Ekologi, miljö och geovetenskap

    Author : Annika Niklasson; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atmospheric corrosion; conservation strategies; formiate; historical organs; organ pipe corrosion; lead; oak wood; formic acid; acetic acid; acetate;

    Abstract : The atmospheric corrosion of lead is investigated, with the aim to improve the understanding of the environmental degradation of historical organ pipes. Fieldwork is combined with laboratory investigations. The field studies included characterization of the organ environment and exposures of lead coupons. READ MORE
