    New study on simplified probabilistic models for predicting phytoextraction timeframes of soil contaminants

    Researchers at Swedish geotechnical institute and Chalmers have published an article in Environmental Science and Pollution Research.

    A study shows that in addition to contaminant stabilization, amendment with biochar and peat can increase N retention while improving microbial capacity to perform important soil functions.

  3. 9 October 2023 Johan Anderberg, CEO of SGI, renewed the agreement alongside Dr. Hidenori Takahashi of PARI.

    SGI collaborates with Japan on soil stabilization from a sustainability and lifecycle perspective

    SGI was visited by the Port and Airport Research Institute (PARI) from October 3 to 5. During the visit, our collaboration agreement was renewed, allowing SGI to further enhance its expertise in soil stabilization.

    There is a high risk of landslides along the Göta River, which can affect both society and individuals. The Swedish Geotechnical Institute is working to reduce the risk of landslide along the 93 kilometer long river.

    New report on landslide risks in a changing climate

    SGI has mapped the risks of landslides along the Swedish river Ångermanälven. The report with maps presents a comprehensive overview of the risk of landslides in the current climate and in the climate of the future.

    Landfill sites can utilize ashes from grate-fire incineration plants for ex-situ stabilization at negative cost, thus preventing PFAS contaminated leachate waters

    Exploring the assessment of ecotoxicity in soils using batch test combined with biotic ligand models

    The results indicate a strong pH-dependent toxicity of the free metal ions in the soil extracts. Using pH-adjusted Cu2+ and Zn2+ concentrations in soil extracts, the toxic responses in spiked soils and field-contaminated soils were similar. This indicates a potential for the calibrated models to assess toxic effects in field-contaminated soils. Consequently, evaluation of a standardized 0.001 M CaCl2 batch test with a simplified BLM can provide the basis for an easy-to-use tool for site-specific risk assessment of metal toxicity to soil organisms.

    Evaluation of direct or indirect methods for assessing the presence of quick clay has been evaluated

    Landslides may cause severe destruction that affects both the individuals and functions vital for society. Direct or indirect methods for assessing the pres-ence of quick clay are evaluated in this study. A combined use can be used for a more cost-effective future planning and decision-making.

    Creep should be included to provide better agreement with the in situ meas-ured settlements and pore pressures

    In the north part of Sweden along the Gulf of Bothnia coastline, organic fine-grained soil is the dominating soil type. Long term field measurements and model predictions suggest that creep should be included to provide better agreement with the in situ measured settlements and pore pressures.

    The charge- and concentration-dependent sorption behavior of a range of PFAS compounds in three organic soil samples has been investigated

    Organic matter is a key component in soils for the sorption of per- and polyfluoro-alkyl substances (PFAS). This study investigates the charge- and concentration-dependent sorption behavior of a range of PFAS compounds in three organic soil samples.

    Intensive Cl cycling in soils

    This study reveal intensive Cl cycling between organic and inorganic forms in forest humus layers, while long-term Clorg accumulation seems more linked with overall deep soil organic carbon stabilization. Thus, humus types and fac-tors affecting soil carbon storage could be used as indicators of potential Clorg formation and accumulation in soils.

    A large number of polycyclic aromatic compounds revealed

    New publication that demonstrates the benefit of combining targeted and non-targeted chemical analysis with bioassay analysis to assess the diversity and effects of PACs at contaminated sites.

    A new wave data is made available

    A 40-year wave dataset, from 1979 to 2019, is made available through an open-access data portal. The wave model domain encompasses the Baltic Sea, Öresund, Kattegat, and Skagerrak.

    Pyrite cinder investigated using a combination of complementary techniques

    This is the second publication in a study of a 60-year-old pyrite cinder deposit in Bergvik, Sweden. A comprehensive mineralogical characterization and speciation of sulfur, Pb and Zn have been carried out.

    Water levels are changing – build wisely!

    We know that heavy rainfall can cause flooding along watercourses and in low-lying areas. We also know that storms can cause flooding and erosion along the coastline and that sea levels are slowly rising. As conditions change, we need to re-think our land-use practices and plan our communities to make them safe and livable for future generations as well.

    Dispersion paths for contaminated sediments investigated

    Two newly published articles present the possibility of dispersion and possible dispersion pathways for contaminants from fibrous deposits.

    Ten national risk areas have been identified

    In a new report, the Swedish Geotechnical Institute (SGI) and the Swedish Civil Contingencies Agency (MSB) have identified ten areas with climate related risks for landslide, flooding and shore erosion.
