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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. Early season BVOC emission for young potted Norway spruce (Picea abies)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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. READ MORE

  4. 3. The link between secondary organic aerosol and monoterpenes at a boreal forest site

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ying Zhou; [2017]
    Keywords : physical geography; ecosystem analysis; BVOC; SOA; Monoterpenes; temperature; relative humidity; wind; Earth and Environmental Sciences;

    Abstract : Secondary organic aerosol (SOA) plays a significant role in climate change by altering the global atmospheric radiation budget. Biogenic volatile organic compounds (BVOCs) are major sources for the formation of SOA. READ MORE

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

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Abstract : 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).

  6. 5. Investigation of possible non-additive behavior in the formation of secondary organic aerosol from a mixture of anthropogenic and biogenic VOC precursors

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : John Falk; [2014]
    Keywords : Volatile organic compounds; Biogenic; Anthropogenic; Secondary organic aerosol; Non-additive; Flow reactor; Scanning Mobility Particle Sizer; Earth and Environmental Sciences;

    Abstract : Secondary organic aerosol (SOA) mass yields were tested for six combinations of two anthropogenic volatile organic compounds (AVOC); m-xylene & toluene, and three biogenic volatile organic compounds (BVOC); α-pinene, myrcene & isoprene. The purpose was to investigate any non-additive results in SOA formation from mixtures of AVOCs and BVOCs by comparing experimental yield with corresponding two-product model yields. READ MORE
