  1. 1. Refining the particulate matter airway deposition arising from indoor cooking-related biomass combustion for children in the Haramaya district in Ethiopia

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Kasper Malmborn; [2023]
    Nyckelord :Air pollution exposure; charcoal; wood; animal dung; low-income setting epidemiology; Technology and Engineering;

    Sammanfattning : Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. LÄS MER

    Sammanfattning : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. LÄS MER

  7. 5. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sanna Sahlin; [2021]
    Nyckelord :Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. LÄS MER
