Sustainability of cities should largely be based on the ecological capital represented by vegetation, which constitutes an alternative for the study of environmental pollution. In order to determine the capacity of sulfur accumulation in tree species, samples of leaf material were taken from 225 trees located in the city of Chihuahua taking into consideration commercial and land uses, mixed and heavy industry and low and middle class residential areas. At the species level, quantities of sulfur exceeded optimal levels for their development. Using General Linear Analysis interactions between species, site and season were tested for sulfur content in each tree, determining a significant interaction between season and site factors (P<0.0235). These results provide data for urban environmental policies and the need for finding species that determine environmental quality. [ABSTRACT FROM AUTHOR]
