16. Tillage effects on soil respiration in Swedish arable soils
Sammanfattning : The amount of carbon (C) present in soil is greater than the sum of C present in terrestrial vegetation and the atmosphere combined. Small changes in soils can therefore affect atmospheric CO₂ levels and ultimately the global climate. LÄS MER
17. Risk assessment of erosion and losses of particulate phosphorus : a series of studies at laboratory, field and catchment scales
Sammanfattning : Phosphorus (P) losses from agricultural land are considered a major contributor to eutrophication in many aquatic ecosystems. Areas more vulnerable to losses of P need to be identified in order to effectively apply mitigation measures aimed at reducing total loads of P. LÄS MER
18. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements
Sammanfattning : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. LÄS MER
19. Stabilization-solidification of high water content dredged sediment : Strength, compressibility and durability evaluations
Sammanfattning : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. LÄS MER
20. Soil Management Strategies to Establish Vegetation and Groundwater Recharge when Restoring Gravel Pits
Sammanfattning : The removal of vegetation and overburden changes the naturalwater purifying processes and thus decreases the groundwaterprotection in gravel pit areas. The sand and gravel depositsusedfor aggregate extraction in Sweden are also often valuablefor extraction of groundwater as a drinking water resource. LÄS MER
