  • Title: Concentrations of metals in soils in the neighborhood of a hazardous waste incinerator: assessment of the temporal trends.
    Author: Vilavert L, Nadal M, Schuhmacher M, Domingo JL.
    Journal: Biol Trace Elem Res; 2012 Dec; 149(3):435-42. PubMed ID: 22569806.
    Abstract:
    The concentrations of arsenic (As), beryllium (Be), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), antimony (Sb), tin (Sn), thallium (Tl), and vanadium (V) were determined in 30 soil samples collected in April 2011 near a hazardous waste incinerator (HWI; Constantí, Catalonia, Spain), which is under regular operations since 1999. The results were compared with those of recent surveys performed in the same zone, as well as with data from a background study (1996-1998). We also assessed the human health risks derived from metal exposure in the area under potential influence of the emissions of the HWI. Manganese was the most abundant element in soils, with a mean value of 316.4 μg/g, followed by Pb and Cu (mean values, 42.5 and 38.2 μg/g, respectively). In contrast, Sb, Cd, and Tl presented the lowest values (0.12, 0.27, and 0.29 μg/g, respectively), while Hg was below its limit of detection. In the period 1998-2011, only As, Cr, Sn, Tl, and V levels presented significant increases in soils. The estimated carcinogenic and noncarcinogenic risks derived from exposure to these metals from soils should not mean any special concern for the population living in the surroundings of the HWI.
