1. Phytoremediation of mercury by terrestrial plants
Sammanfattning : Mercury (Hg) pollution is a global environmental problem. Numerous Hg-contaminated sites exist in the world and new techniques for remediation are urgently needed. LÄS MER
2. Development of a Low Cost Remediation Method for Heavy Metal Polluted Soil
Sammanfattning : High concentrations of heavy metals in the soils have potential long-term environmental and health concerns because of their persistence and accumulation tendency in the environment and along the food chain. This study was aimed at studying the feasibility of heavy metals removal from the soil using plants naturally growing in the surroundings of selected polluted sites in Tanzania and soil application of the sorbent materials zeolite and autoclaved aerated concrete (AAC).

3. Phytoremediation of soil contaminated with per- and polyfluoroalkyl substances (PFAS)
Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) are anthropogenic compounds recognised for their persistence, mobility and potential toxicity. This thesis examines the efficacy of phytoremediation as a potential technique for managing PFAS-contaminated soil and groundwater. LÄS MER
4. Phytoremediation of soil contaminated with petroleum hydrocarbons and trace elements
Sammanfattning : The rapid urbanization and industrialization has led to an increase of disposal petroleum hydrocarbons (PHC) and trace elements (TE) into the environment. These pollutants are considered as the most toxic contaminants in the world due to their persistence in the environment, and the long range of toxicological effects for living beings. LÄS MER
5. Opportunity Windows and Added Value of Gentle Remediation Options for Contaminated Land Management
Sammanfattning : Well-functioning, healthy soils are increasingly recognized as vital to human well-being, but soil contamination impairs the capacity of soils to perform their essential functions and provide humans with ecosystem services (ES). Contaminated land poses risks to human health and the environment, which must be managed, but also constitute an important and underutilized land and soil resource for providing ES in urban areas through phytomanagement with gentle remediation options (GRO) – nature-based solutions using plants, fungi, bacteria, and soil amendments to manage risks at contaminated sites while also improving soil functionality.
