  3. 2. Acidification trends in Swedish lakes : an assessment of past water chemistry conditions using lake sediments

    Författare :Tom Korsman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palaeolimnology; acidification history; alkalization; acid deposition; land-use; lake sediments; near infrared spectroscopy; diatoms; multivariate calibration; Sweden;

    Sammanfattning : This thesis presents temporal perspectives of lake acidification in Sweden. Sediment records have been used to study timing, trends and causes of acidification, and two different techniques for assessing past lake-water acidity are presented. LÄS MER

  4. 3. HNO3-Induced Atmospheric Corrosion of Copper, Zinc and Carbon Steel

    Författare :Farid Samie; Christofer Leygraf; Carlos Arroyave; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nitric acid; deposition velocity; mass transport; air velocity; relative humidity; Chemistry; Kemi;

    Sammanfattning : The role of nitric acid (HNO3) on the atmospheric corrosion of metals has so far received little or no attention. However, the last decades of decreasing sulphur dioxide (SO2) levels and unchanged HNO3 levels in many industrialized countries have resulted in an increased interest in possible HNO3-induced atmospheric corrosion effects.
