title: Monitoring environmental levels of trace elements near a hazardous waste incinerator: human health risks after a decade of regular operations.
abstract: In 1998, we initiated an environmental surveillance program of the only hazardous waste incinerator (HWI) in Spain. The concentrations of a number of metals (As, Be, Cd, Cr, Hg, Mn, Ni, Pb, Sn, Tl, and V) were analyzed in soil and vegetation samples collected around the facility. Since then, periodical measurements of these same elements have been performed in both matrices. In 2009 and 2010, soil and vegetation samples were again collected, and the levels of the above elements were determined. In general terms, the temporal trends in metal concentrations were not homogeneous, showing significant changes between the baseline and the latest surveys. Metal levels in soil and herbage samples analyzed in the current survey were similar to recent data reported for other urban and industrial areas, being notably lower than the reference values set by national regulatory organisms. Moreover, more than 10 years after regular operations of the HWI, exposure to metals would not mean, either now or in past surveys, any carcinogenic or non-carcinogenic health risks for the population living in the neighborhood.
