Defining potential valuables through the characterisation of lake sediments: case study in Arkelstorp bay, Sweden

Abstract

Highlights Lake sediments were characterised in their nutrient content, and it was found that the material could be an interesting source as a replacement for mineral fertilizer. Sediments contained no elevated amount of metals, but the cadmium content could limit the use of the material as fertiliser in agriculture. Sediments were analysed for organic contaminants, and none were found.
