  1. 11. Chemical characteristics of atmospheric aerosols : the influence of natural and man-made sources and sinks

    Författare :Michael Norman; Jost Heintzenberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meteorology; Meteorologi; meteorologi; Meteorology;

    Sammanfattning : In order to improve the understanding of the climatic and environmental effects of atmospheric aerosol particles, knowledge about their sources, sinks, chemical and physical characteristics as well as transportation in the atmosphere is needed. This thesis examines the water-soluble chemical characteristics of aerosol particles and precipitation and their interaction with trace gases. LÄS MER

  3. 12. Bioremediation of Toxic Metals for Protecting Human Health and the Ecosystem

    Författare :Aminur Rahman; Abul Mandal; Jana Jass; Björn Olsson; Pawel Kaszycki; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heavy Metals; Pollution; Accumulation; Remediation; Human Health; Bacteria; Genome Sequencing; de novo Assembly; Gene Prediction; Biology; Biologi; Bioteknik;

    Sammanfattning : Heavy metal pollutants, discharged into the ecosystem as waste by anthropogenic activities, contaminate drinking water for millions of people and animals in many regions of the world. Long term exposure to these metals, leads to several lethal diseases like cancer, keratosis, gangrene, diabetes, cardio- vascular disorders, etc. LÄS MER

  4. 13. Safe Nutrient Recovery from Human Urine - System and Hygiene Evaluation of Alkaline Urine Dehydration

    Författare :Jenna Senecal-Smith; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Only 7% of the world’s wastewater receives tertiary treatment, while the rest is causing eutrophication, hypoxia and climate change through the plant nutrients found in excreta, particularly urine. If managed adequately, urine can be used as a fertiliser because it contains the same nutrients as the fertilisers used to produce food world-wide. LÄS MER

  5. 14. The Story of Phosphorus : Sustainability implications of global phosphorus scarcity for food security

    Författare :Dana Cordell; Stuart White; Jan-Olof Drangert; Julie Wilk; Johan Rockström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; global phosphorus scarcity; peak phosphorus; global food security; sustainable resource use; food production and consumption system; transdisciplinary; systems thinking; global fosforbrist; peak fosfor; global matsäkerhet; hållbar resursanvändning; system för produktion och konsumtion av mat; transdisciplinaritet; systemtänkande; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : The story of phosphorus began with the search for the philosopher’s stone, and centuries later the critical role of phosphorus in soil fertility and crop growth was highlighted. Eventually, phosphorus was implicated in the global environmental challenge of eutrophication. LÄS MER
