Abstract
The objective of this study was to determine the As and Sb contents in soils from the Murcia Region of Spain and the possible
relationship between the mineralogical composition, soil properties, and As and Sb concentrations. In this study, 490 samples were
selected from areas with different characteristics in order to study As and Sb variability. Results show that As and Sb concentrations
are positively correlated with the phyllosilicate and quartz content but negatively correlated with the calcite content. The generic
reference level (GRL) for these elements was determined according to the Spanish legislation. Established GRL values vary
according to the established mineralogical groups, suggesting that GRL has to be determined considering the lithological
characteristics of the study area
