Leachability of arsenic and lead from autoclaved aerated concrete (Siporex) in a landfill at Näsudden, Skelleftehamn. (English)
Abstract [en]

The expansion of an industrial area in Näsudden, Skelleftehamn, will require extensive groundwork. An old landfill in the area, partly consisting of autoclaved aerated concrete (siporex), is intended to be used for constructing the new industrial site. The conditions for how the material can be used is, however, controlled by a variety of parameters. This is a part study of the evaluation of how the masses should be treated. The purpose of this study is to evaluate how the presence of siporex affects the mobility of arsenic and lead in the landfill area. Soil and groundwater samples from 10 sample points from the landfill area were collected and analyzed for its metal content. The results were used for calculating the solid/liquid partition coefficient (Kd) for the desorption of samples with or without siporex. Results indicate that the mobility of arsenic is higher in the samples with siporex due to the higher pH in the leachate. No correlation could be found between the influence of siporex and mobility of lead in this study. Further studies are needed in a controlled environment to assess how siporex affects the mobility of arsenic and lead.
