  1. 1. Investigation of Potentially Toxic Elements in Agriculture Soil : Greenhouse and Open-field Farming in Türkiye

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Furkan Özkan; [2023]
    Keywords : Agriculture; Fertilizer; Organic Farming; Potentially Toxic Elements PTE ; Tarım; Gübre; Organik Tarım; Potansiyel Toksik Elementler PTE;

    Abstract : Greenhouse food production has intensive fertilizer practices, and it leads to contamination in the soil and food chains. This study investigated the potentially toxic elements (As, Pb, Zn, Cd, Cr, Cu, and Ni) (PTE) in agriculture soil and their bioaccumulation by dragon fruit and banana. READ MORE

  3. 2. Characterizing particulate carbon using dielectric property measurements

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Madeleine Syk; Joakim Vollmer; [2018]
    Keywords : black carbon; elemental carbon; carbonaceous aerosols; soot; fullerene C60; multiwalled carbon nanotubes; mesoporous carbon; impedance; dielectric; snow melting; capacitance; waveguide;

    Abstract : Interest in effects of carbonaceous particles in the atmosphere has recently taken an upswing due to knowledge of how these particles affect our environment. Carbonaceous aerosols are characterized by their dark color, giving them the ability to absorb both incoming and outgoing radiation of all wavelengths in the atmosphere. READ MORE

  4. 3. Extended phenotypes in the canopies of Norway spruce

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Christofer Johansson; [2016]
    Keywords : extended phenotypes; Cinara spp.; Picea abies; associated organisms; C:N ratio; growth rate; aphid abundance;

    Abstract : The extended phenotype may help us understand how genetically determined trait variation in foundation species can influence associated organisms. Today, there is no existing demonstration of how genetically determined trait variation in Norway spruce (Picea abies) may affect associated organisms in tree canopies. READ MORE

  5. 4. Biophysical changes following landscape restoration : in Changting model restoration site in Fujian province, southern China

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Martin Ewertson; [2016]
    Keywords : afforestation; biomass carbon pools; carbon and nitrogen in soil; broadleaves enrichment; eroded red soil;

    Abstract : China has promised to tackle climate change by decreasing its emission and promote carbon sinks primarily by forest plantations and restorations. There is a growing debate about the impacts of large-scale restorations using few fast-growing species on the kind of ecosystem we are creating and its adaptation to the future environmental conditions.

  6. 5. Determination of dioxins in Cretaceous strata from the South of Sweden. : Can the environmental anthropogenic pollutant dioxin be of natural origin ?

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Kelly GUILBOT; [2012]
    Keywords : old clay layers; octachlorodibenzo-p-dioxin; high resolution gas chromatography-high resolution mass spectrometry; analyzer-isotopic ratio mass spectrometry; isotopic dilution.  ;

    Abstract : Eleven sediment samples from different geological layers and four fossils from the South of Sweden were collected and estimated to be 80 million years old (approximately late of Cretaceous period). The samples were analyzed for polychlorinated dibenzo-p dioxins (PCDD/Fs) to investigate whether these samples are likely to contain dioxins from a natural formation. READ MORE
