- Abstract
In this article we report the relationships between heavy metals (Pb, Cd, Zn, Cu) in soil and settleable particulate matter using data from 6 yr at six different sampling points within Cartagena, a Spanish Mediterranean city. The use of enrichment factors and factor analysis allowed us to predict the major sources of these metals. Soils were classified as one of three types: soils from polluted zone L, soils from polluted zone Z, and non-polluted soils. Settleable particulate matter was also classified in the following three groups: Industrial zone, Urban zone, and Intermediate zone. Enrichment factors showed that soils from polluted zone L are enriched in Pb and Cd when compared with soils from polluted zone Z, and soils from polluted zone Z are enriched in Zn and Cu when compared with soils from polluted zone L. In this context, soils from polluted zones L and Z are identified as specific sources of metals in the settleable particulate matter samples. We also suggest the importance of anthopogenic contribution of metals to soil-enrichment from ancient times up to the present. This process was most severe during the XIX century, when our city suffered an important industrial development. The concentration of these heavy metals are also affected by regional meteorological conditions, which include scarce rainfalls and a significant wind dispersion of soil aerosols.
