Chemical and magnetic properties of wood biomass growing in different environmental conditions

The data contain results from chemical and magnetic analyses of ash samples obtained from the combustion of wood biomass in a laboratory muffle furnace. The analyzed biomass originated from nine tree species growing under different environmental conditions (bedrock, soil, waste, dust deposition). Samples of wood, bark, and small twigs were analyzed. The aim of the study was to determine how environmental growing conditions influence the ecological quality of potential fuels derived from wood biomass.
