Phytoremediation is a technique using the ability of plants to absorb pollutants in their biomass from contaminated soils and remediate it. The plants are then harvested and the soil gets purified. This method is more environmental-friendly than the normally used methods for soil remediation. Glasriket in Småland is an area with large amount of pollutants including arsenic, cadmium and lead. This area must be cleaned from these metals because of the high threat to the environment ant the health of people who live here.

Hemp is a versatile plant with many uses that has been around for thousands of years. The plant is highly adaptable andwill cultivate in almost any soil. It has excellent remediation properties and has shown to be relatively consistent when itcomes to crop yields. The aim of this literature survey is to examine how hemp can be used to be considered asustainable energy crop in Sweden through database searches and interviews. Hemps characteristics as an energy cropand its remediation properties is evaluated and compared with other plants that are used in Sweden.

Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.

Fytoremediering är samlingsnamnet på den marksaneringsmetod som utnyttjar växters förmåga att tolerera, extrahera, degradera eller stabilisera olika typer av föroreningar i mark och vatten. Att växters olika egenskaper genom historien använts för att utveckla och förbättra förutsättningar i bl.a. jordbruket är ingenting nytt. Vi lever i en tid där ett allt högre tryck på naturen och jordens resurser påverkas av att vi blir fler och fler människor som ska dela på dem. I våra postindustriella städer finns många restytor påverkade av de verksamheter som tidigare huserat där, med förorenad och förstörd mark som följd.

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.
