Monitoring metals in the population living in the vicinity of a hazardous waste incinerator: levels in hair of school children.

摘要: Hair samples of 134 school children (12-14 yr old) living in three residential zones the vicinity a new hazardous waste incinerator (HWI) (Constanti, Tarragona County, Catalonia, Spain) were analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) for arsenic (As), beryllium (Be), cadmium (Cd), chromium (Cr), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), tin (Sn), thallium (Tl), and vanadium (V) concentrations. These concentrations compared with those obtained baseline survey performed same area during period construction HWI. Current mean ranged from values under respective limit detection (As, Be, Cd, Tl, V) to 0.70 0.86 microg/g Hg Pb, respectively. In comparison survey, levels Cr, Mn, Ni, Sn showed significant reduction, whereas similar. No differences observed according sex children. However, some noted, especially Pb respect specific zone residence. general terms, current metal hair are similar or even lower than recently reported number industrial areas various regions countries.
