  4. 8. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Sara Camiolo; [2021]
    Keywords : eutrophication; rivers; streams; phosphorus;

    Abstract : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.

  5. 9. Life cycle assessment of hybrid systems for rural electrification in Bolivia

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Sandu Seres; [2021]
    Keywords : Diesel; Stirling; Photovoltaic; impact category;

    Abstract : Bolivia is a developing country in South America. Many rural communities still lack access to electricity. The extension of the National Grid System to all rural communities is not feasible due to economic and topographic challenges as well as the environmental problems that may arise. To tackle these problems, Off-grid solutions are implemented. READ MORE

  6. 10. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Iwan; [2021]
    Keywords : Total Organic Carbon TOC ; Total Organic Nitrogen TON ; Land Cover Change; Sweden; WaterBase; Earth and Environmental Sciences;

    Abstract : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. READ MORE
