Chemometric analysis of heavy metal content for various environmental matrices in terms of their use in biomass thermal processing

Abstract

Chemometric analysis was performed to determine the heavy metal content, such as Zn, Cd, Ni, Mn, Cu, Pb, and Fe, in 36 samples of Scots Pine taken from 9 locations within the Upper Silesian Industrial Basin. The samples, after being pre-processed, were examined for the above elements through the use of atomic absorption spectroscopy (AAS). The highest concentration of heavy metals was discovered in samples from Jaworzno. Based on the concentration assessment, the relationship between element quantity, sampling location, and matrix type has been determined, and definite element group co-existence has been confirmed and described. © Versita Sp. z o.o.
