  1. 1. Systems Perspectives on Modelling and Managing Future Anthropogenic Emissions in Urban Areas : Nitrogen, Phosphorus and Carbon Studies in Stockholm, Sweden

    Author : Jiechen Wu; Maria E. Malmström; Daniel Franzén; Daniel Müller; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Anthropogenic emissions; Urban development; Future; Substance flow analysis SFA ; DPSIR.;

    Abstract : Managing anthropogenic emissions in urban areas is a major challenge in sustainable environmental development for cities, and future changes and increasing urbanisation may increase this challenge. Systems perspectives have become increasingly important in helping urban managers understand how different changes may alter future emissions and whether current management strategies can efficiently manage these emissions.

  2. 2. Particle emissions from residential wood and biodiesel combustion

    Author : Robin Nyström; Christoffer Boman; Dan Boström; Markus Broström; Michael Strand; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Combustion; biomass; wood; biodiesel; particulate matter; emissions; aerosols; physicochemical properties; size distribution; PAH;

    Abstract : Emissions from anthropogenic combustion sources, such as vehicles and biomass combustion, contribute significantly to ambient particulate matter (PM) both on a local and global scale. Exposure to ambient PM and air pollution in general is linked to a variety of different health effects and it has been estimated that as many as 2. READ MORE

  3. 3. Application of Passive DOAS using Scattered Sunlight for quantification of gas emissions from anthropogenic and volcanic sources

    Author : Claudia Rivera; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; nitrogen dioxide; DOAS; gas emission; sulphur dioxide; volcanic; formaldehyde.; scattered sunlight; anthropogenic;

    Abstract : Monitoring of gas emissions from natural and anthropogenic sources is important due to the negative effects of these emissions on human health, atmospheric quality and ecosystems. Concern over air pollution has increased the need to develop measurement techniques suitable for gas flux determination. READ MORE

  4. 4. Reducing ships' fuel consumption and emissions by learning from data

    Author : Fredrik Ahlgren; Marcus Thern; Maria E. Mondejar; Cecilia Österman; Ann-Charlotte Larsson; Erik Dahlquist; Linnéuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shipping; energy efficiency; orc; machine learning; emissions; Sjöfartsvetenskap; Maritime Science;

    Abstract : In the context of reducing both greenhouse gases and hazardous emissions, the shipping sector faces a major challenge as it is currently responsible for 11% of the transport sector’s anthropogenic greenhouse gas emissions. Even as emissions reductions are needed, the demand for the transport sector rises exponentially every year. READ MORE

  5. 5. Characteristics of fresh and aged carbonaceous aerosol from anthropogenic combustion sources

    Author : Erik Nordin; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; biomass combustion; gasoline vehicle exhaust; polycyclic aromatic hydrocarbons; secondary organic aerosol; soot; mass-mobility relationship; emissions; toxicity;

    Abstract : Emissions from anthropogenic combustion sources, such as light duty vehicles and small scale biomass combustion, contribute significantly to ambient aerosol particle concentrations both on local and global scales. These emissions have controlling impacts on public health and global climate. READ MORE
