  1. 1. Temporal trends of 4-Hydroxychlorothalonil in maternal serum samples, 1997-2015

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

    Författare :Elin Wällstedt; [2023]
    Nyckelord :Biomonitoring; human exposure effects; environmental exposure; fungicide; pregnancy; pregnant women; chlorothalonil; CHT; 4-hydroxy-chlorothalonil; 4-OH-CHT; Earth and Environmental Sciences;

    Sammanfattning : Agricultural fungicides are extensively used for infestation control, resulting in residues of these compounds in food. Human exposure to environmental contaminants might occur via different routes, such as inhalation, skin contact, or ingestion. Exposure to several pesticides has been associated with adverse human health outcomes. LÄS MER

    Sammanfattning : Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A.

  7. 5. Economic Situation of Indigenous People in Bangladesh: A study on the Chittagong Hill Tracts

    Kandidat-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Abul Hasnat Mohammed Alamgir; abul alamgir; abul alamgir; abul alamgir; [2021]
    Nyckelord :The Chittagong Hill Tracts CHT of Bangladesh was full of natural resources like water; river; forest; agriculture; land. Various agencies like government and non-government local; national; and international have undertaken and implemented development programs in the CHT at different times encompassing those natural resources to develop the CHT economy and contribute to the overall economic situation. Even though; the economic situation of the indigenous people in CHT remains unchanged and more than eight hundred thousand indigenous people in CHT are presently living with an imbalanced economy; poverty and hunger; low income; unemployment. A political agreement and the peace treaty has been signed in 1997 to end human life; restore the CHT indigenous people’s economy as well as establish peace in CHT. This study has collected both qualitative and quantitative data from primary and secondary sources to see and analyze the present economic situation of the indigenous people in CHT after this peace accord. Key Words: Chittagong Hill Tracts; Bangladesh; Indigenous People; Economy; Peace Accord; Social Sciences;

    Sammanfattning : The Chittagong Hill Tracts (CHT) of Bangladesh was full of natural resources like water, river, forest, agriculture, land. Various agencies like government and non-government (local, national, and international) have undertaken and implemented development programs in the CHT at different times encompassing those natural resources to develop the CHT economy and contribute to the overall economic situation.
