    Sammanfattning : Vegetation plays an important role in the partitioning, transport and fate of hydrophobic organic contaminants (HOCs) in the environment. This thesis aimed at addressing two key knowledge gaps in our understanding of how plants exchange HOCs with the atmosphere: (1) To improve our understanding of the uptake of HOCs into, and transfer through, leaves of different plant species which can significantly influence the transport and fate of HOCs in the environment; and (2) To evaluate an experimental approach to measure fluxes of HOCs in the field.

  3. 2. Urban microclimate and surface hydrometeorological processes

    Författare :Christer Jansson; Per-Erik Jansson; David Gustafsson; Chen Delian; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CoupModel; ENVI-met; roughness sub-layer; urban heat island; Physical geography; Naturgeografi;

    Sammanfattning : The urban near surface atmosphere is of great concern since it affects the climate to which an increasing amount of people are immediately exposed. This study investigated the microclimate in central Stockholm in terms of the thermal conditions in the 0-2. LÄS MER
