2. 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; Chalmers tekniska högskola; []
   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

5. 3. Atmospheric Corrosion of Historic Lead Organ Pipes

   Author : Annika Niklasson; Chalmers tekniska högskola; []
   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

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

   Author : Ingvar A Bergdahl; Avdelningen för arbets- och miljömedicin; []
   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

7. 5. Biomarkers of fish consumption and risk of stroke or myocardial infarction

   Author : Maria Wennberg; Jan-Håkan Jansson; Ingvar Bergdahl; Maria Albin; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fish consumption; omega-3 fatty acids; eicosapentaenoic acid; docosahexaenoic acid; methylmercury; selenium; lead; cadmium; stroke; myocardial infarction; erythrocytes; food frequency questionnaire; Environmental medicine; Miljömedicin; Epidemiology; epidemiologi; hälso- och sjukvårdsforskning; health services research; medicin; Medicine; Environmental Science; miljövetenskap; näringslära; Nutrition;

   Abstract : The effect of fish consumption on the risk of cardiovascular disease has been extensively studied. Omega-3 fatty acids present in fish, namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been found to have beneficial effects through several mechanisms. In addition, selenium, an antioxidant, may be protective. READ MORE
