    ABSTRACT This paper analyzes the metal pollution in natural, agricultural and mineral-industrial soils in the Sierra of Cartagena-La Union and its adjacent area. The analysis was conducted on 52 soil samples randomly selected and 23 samples from the bed of the channels draining to the Mar Menor and the Mediterranean sea. The results indicate high concentrations of metals that exceed, in many cases, the maximum allowable by the relevant laws of various countries, including Spain. Of note is the excessive contamination by lead (Pb) and Cinz (Zn) that doubles or even triples the maximum of the most permissive laws.
