  1. 1. Air quality around preschools in Gothenburg: an evaluation of measurement methods

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Emma Forsmalm; [2023-06-21]
    Nyckelord :low-cost sensors; passive diffusion samplers; pick-ups and drop-offs; regulatory measurements;

    Sammanfattning : In this study the air quality around four different preschools, chosen to represent different local traffic environments, was measured and the measurement methods used were evaluated. The aim was to compare the information retrieved using different methods, discuss the possible applications of them and finally see if more specific activities, in this case pick-ups and drop-offs, could be seen in the data retrieved.

  2. 2. Freight Transport in the Car-Free City : Towards a more sustainable urban freight sector

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Melisa Marta; [2023]
    Nyckelord :Car-free city; sustainable urban freight transport; urban consolidation center; cargo bicycles;

    Sammanfattning : Freight transport of goods is an indispensable part of everyday life. Without it there would be no delivery of products such as food, water, construction material, technology, furniture, clothes and society, as we know it today, would collapse.  However, there are more and less sustainable ways of transporting goods.

    Nyckelord :;

    Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER
