  1. 1. BVOC emission variability for Norway spruce (Picea abies) in Hyltemossa, Sweden

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Alexandra Arnsteg; [2022]
    Nyckelord :BVOC; isoprene; monoterpenes; induced emission; light dependency; temperature; Norway spruce.; Earth and Environmental Sciences;

    Sammanfattning : Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack.

  3. 2. Estimation of the potential BVOC emissions by the different tree species in Malmö

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Larissa Lisa Gesa Scholz; [2019]
    Nyckelord :BVOC emissions; isoprene; monoterpene; air quality; Malmö; Earth and Environmental Sciences;

    Sammanfattning : BVOC emissions from trees contribute to ozone and secondary aerosol formation and therefore have an impact on air quality. The two most abundant BVOCs emitted from trees are isoprene and monoterpenes. LÄS MER

  4. 3. Early season BVOC emission for young potted Norway spruce (Picea abies)

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Erica Jaakkola; [2019]
    Nyckelord :Physical Geography and Ecosystem analysis; BVOC; Norway spruce; PTR-TOFMS; photosynthesis; Earth and Environmental Sciences;

    Sammanfattning : Biogenic volatile organic compounds (BVOC) are emitted naturally from the biosphere to the atmosphere and are a part of the global carbon emissions. BVOCs are contributing to around 5-10% of the total net carbon exchange to the atmosphere. LÄS MER

  5. 4. Is there new particle formation in the marine boundary layer of the North Sea?

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Natalia Kelbus; [2014]
    Nyckelord :Geography; Physical Geography; aerosol particles; new particle formation; nucleation; particle size distribution; NanoMap; Science General; Earth and Environmental Sciences;

    Sammanfattning : The effect of aerosol particles on climate and the human health emphasizes the necessity to focus on the research about aerosol particles. Aerosol particles emitted due to anthropogenic activities increase the scattering and absorption of solar radiation in the atmosphere which leads to an increased cooling of the climate (direct effect).

  7. 5. Biogenic volatile organic compound emissions from Willow trees

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Md. Ahsan Mozaffar; [2013]
    Nyckelord :atmosphere; Salix; Willow; biogenic volatile organic compounds; Isoprene; climate; BVOC; geography; physical geography; Earth and Environmental Sciences;

    Sammanfattning : In August 2012, emissions of biogenic volatile organic compounds (BVOCs) from willow (Salix) trees were measured in Lund, southern Sweden. Sweden has more than 16000 ha of short rotation willow plantations for biofuel production and willow trees are suspected to emit substantial amounts of BVOC to the atmosphere. LÄS MER
