  1. 1. Metaller i Vombsjön - Mygglarver som bioindikator för miljöövervakning

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Siri Bengtsson; [2024]
    Nyckelord :Bioindicators; Chironomidae; Freshwater source; Lake Vomb; Metal concentrations; Pollution; Sediment sampling; Earth and Environmental Sciences;

    Sammanfattning : This study investigates concentrations of eight metals (Cu, Zn, Cd, Pb, Hg, Cr, Ni, As) in the freshwater resource Lake Vomb, located in the south of Sweden (Scania), and explores the potential use of deformed Chironomidae larvae as bioindicator. Sediment samples from six locations were analysed against threshold values from the Swedish Agency for Marine and Water Management and background values from the Swedish Environmental Protection Agency.

  2. 2. Microplastics in Scanian wetlands : Sege river & Kävlinge river

    Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

    Författare :Ludvig Stoltz; Pernilla Leijon; [2023]
    Nyckelord :plastic pollution; wetlands; microplastics; Scania; density separation; plastföroreningar; våtmarker; mikroplaster; Skåne; flotteringsmetod;

    Sammanfattning : It is estimated that 75 million tons of plastics waste is currently in the ocean and expects to increase in line with plastic consumption. Plastic items in natural or aquatic environments are fragmented into smaller pieces called microplastics. Microplastics can enter rivers and lakes through sewage water to end up in wetlands where they sediment. LÄS MER

  3. 3. Näringsämnen och metaller i sediment och blåmusslor från Hanöbukten - En analys av marin miljöpåverkan från massabruk

    Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Elvira Källberg; [2023]
    Nyckelord :Föroreningar; massabruk; blåmusslor; sediment; Earth and Environmental Sciences;

    Sammanfattning : The pulp industry is important for creating sustainable paper products and for the Swedish economy. However, the industry has historically polluted marine environments through its emissions. This study aims to analyse the effects of the pulp mill Södra Cell Mörrum on the marine recipient Hanö Bay in the southern Baltic Sea. LÄS MER

  4. 4. Deposition av Black carbon i sjöar efter den stora skogsbranden i Västmanland 2014

    Magister-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC); Lunds universitet/Miljövetenskaplig utbildning

    Författare :Danny Wong; [2023]
    Nyckelord :Black carbon; BC; climate; environment; wildfire; boreal forests; lake sediments; Västmanland.; Earth and Environmental Sciences;

    Sammanfattning : Black carbon (BC) is produced during incomplete combustion of Biomass and fossil fuels. BC and other carbonaceous pollutants have characteristics that affect the climate, environment, and human health. Historically, BC emissions have been measured and monitored in the atmosphere, and BC emissions to the air are quite well documented. LÄS MER

  5. 5. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :William Mörtsjö Zung; [2023]
    Nyckelord :;

    Sammanfattning : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).
