Resumen:
Heavy metals in street dust represent a risk to the human health due to
their toxicity, persistence and bioaccumulation. Using the US
Environmental Protection Agency (USEPA) assessment, here, we review the
human health risks of such dust world-wide. The street dust in such
cities is contaminated by As, Cd, Cr, Cu, Hg, Mn Ni, Pb and Zn beyond
the median levels of the world soil background values. Among these
elements, the median values of the hazard risk indices (non-carcinogenic
risk) are highest for As, Cr and Pb and the median values of the risk
indices (carcinogenic risk) for As are in the tolerable risk range for
children and adults and in the case of Pb, the median value of the
carcinogenic risk indices are also in the tolerable range for children.
We emphasize that the level of heavy metals in street dust pose a
considerable risk to the human health and require monitoring and
approaches to reduce such toxic levels.
