Abstract

A method was created for quantitative and qualitative analyses of different PBDE´s in various matrixes. A mixture of PBDE congeners was used to make calibration curves, and acetone and cyclohexane was used as solvents for the extraction. Analyses were performed using a GC-MS sector instrument. The method was tested on sediments from the Netherlands. Recovery tests were carried out on soil from Kroer in Ås.

Abstract

Forest owners get only a nominal pay when delievering forest residues for energy purposes. At the same time there might be negative environmental effects as nutrient loss and production loss. Compensation measures could be ash disposal and fertilization. This has a cost, but due to sustainability restrictions compensation measures might be seen as obligatory. Other negative environmental effects include possible effects on biodiversity and acidification. Positive effects include impact on GHG balance and reduced silvicultural costs. We study this problem from the forest owner?s view and from the society?s view in a cost-benefit context. The results vary with physical inputs as deposition and soil type and with assumptions concerning economic variables as shadow price of carbon.
