Environmental contamination is a global concern today and the level of contamination continues to grow due to rapid population growth, increased industrialization, aggressive agricultural practices, and other anthropogenic activities. There are several conventional methods which involve physical and chemical processes such as excavation, soil washing, chemical oxidation, thermal treatment etc. These conventional methods require the use of energy and heavy equipment which make them to be expensive and unstainable. Phytoremediation, the use of plants to remediate contaminated sites, presents promising potentials such as being eco-friendly and cost effective, especially with sites of low or moderate contamination, though more research is required to investigate and support the evidence of its benefits. Despite its promising potentials, the practice of phytoremediation has received less attention, probably due to lack of knowledge of its efficiency. The choice of plants used in phytoremediation is, among other factors, an important aspect in planning and implementing phytoremediation projects. In this master thesis, data from various pot and field studies about the potential of different plant species, were gathered and used to develop a searchable database. The database is intended to facilitate plant selection and serve as a guide to practitioners, researchers, and other non-practitioners in planning an efficient and effective phytoremediation project. In addition to data obtained from literature review, a survey was conducted among stakeholders and experts in Sweden to incorporate their inputs in the development of the database. The data collected from various studies indicate that there are more studies on phytoremediation in Europe and North America. The literature review also showed that most of the studies are being reported in scientific articles. The database is projected to subsequently serve as a national repository of phytoremediation data for Sweden.
