  1. 1. Organohalogens in coniferous forest soil

    University dissertation from Linköping : Linköpings universitet

    Author : Olof Hjelm; Linköpings universitet.; Linköpings universitet.; [1996]

    Abstract : This thesis is focused on naturally produced organohalogens in soil. It was long assumed that organohalogens found in the environment were mainly of anthropogenic origin, but recent research has shown that large amounts of naturally produced organohalogens are stored in terrestrial environments.

  3. 3. The spectral reflectance of coniferous tree stands and of barley influenced by stress : an analysis of field measured spectral data

    University dissertation from Stockholm : Stockholm University

    Author : Johan Kleman; Stockholms universitet.; [1985]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; spectral reflectance; field measurement; middle infrared; crops; fertilisation; irrigation; coniferous forest; helicopter; measuring geometry;

  4. 4. Monoterpenes from the boreal coniferous forest : their role in atmospheric chemistry

    University dissertation from Stockholm : Stockholm University

    Author : Robert Janson; Stockholms universitet.; [1992]

    Abstract : The goal of this work has been to increase our knowledge of the role of the monoteipenes emitted by the boreal coniferous forest in atmospheric chemical processes. To this end, measurements of air concentrations and emission rates have been made in forests of Scots pine (Pinus sylvestris) and Norwegian spruce (Picea abies) at 4 sites throughout Sweden, during the summers of 1989 and 1990.
